AGPS PATCH
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
List of officially supported devices is at the bottom of this post.
Use this if you're having GPS issues (unreliability, no functionality, etc.)
This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)
Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.
Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.
Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.

Rules For Posting Questions:
Read the Notes Section first. I will refuse to answer questions that can be answered by some reading. If it is based upon something in the Notes Section, REFER TO THE NOTE when asking.
Answer the following questions: What ROM you are using?, What kernel are you using?, What GPS apps you have installed?, Where is your general location?, Are you using a case?, Has your GPS worked fine before?, Does it work fine with some apps and not others?, What else happened around the time your GPS stopped working? -AND- Have you reviewed the Notes Section?
DO NOT criticize the user of custom third-party NTP pools and xtra.bin data as dangerous. You obviously HAVE NOT read the Notes section OR reviewed the concurrent branch 2.x to discover it offers the standard NTP pool and Qualcomm-based xtra.bin server.
Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.
NOTES Section:
This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

Thanks Section
While this has gone a long distance since its inception, I want to still send thanks to Angeldeath for permitting me to take his early work and start tweaking it for HTC Inspire 4G users. This inevitably led to what we have here today.
Thank you to all those who joined and participate in the testing community. Without their help, I couldn't get enough data to know how well this works on different devices and in various regions of this planet we call Earth.
Thank you eagleeyetom, husky69, and tamagotono for their work in building an ADB pushing environment for Windows and for Linux respectively.
If you are happy with the patch and find this thread useful, please consider pressing the "Thanks" button on any of my posts on this thread. You may also consider rating this thread with five stars if you're satisfied. You may do so just below "Search This Thread" on the right-side at the top of this post.

REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
Currently, this is tentative support.
Tentative support is based upon reports from users of this device who decided to use the patch and report back on their own.
Reports indicate great success.
Holy crap I literally locked on in less than 5 seconds. Also it didnt take a few seconds after that to "correct" like it used to. I use MyTracks daily and I this will be a big help! Thanks!
Also, I had to use the alternate CWM 3.x file to flash. Worked great and flashed in less than 10 seconds.
CM10 11/25 Nightly
Be careful with this on the Blaze. The blaze uses a 2nd GPS configuration file called loc_parameter.ini as well. That is where the AGPS settings are defined, as well as some of the hardware settings.
I would recommended modifying the gps operation mode flag in that file from 'standalone' to 'speed' or 'accuracy'.
The only parameter I would change otherwise is the NTP server(s)... and I think those are still in gps.conf
If you have trouble locking on, just get GPS Test from Google Play and choose Update AGPS from the settings menu. After that, GPS fixes will be much quicker.
Our device uses both GPS and GLONASS (the Russian equivalent to GPS), so the standard tweaks that work in other devices may not work as expected on the Blaze.
Just some cautionary 2 cents from someone who's done a fair amount of GPS tweaking

I wouldn't touch the NTP servers as my Notes discuss. And, if someone is so fearful of using my DNS pool of Stratum II servers, I would suggest using the 2.x branch which still uses the NTP.ORG server pool. However as I proven, NTP.ORG sucks for mobile network devices as it relies on a lot of people who provide an NTP server on a home cable connection, etc.
GLONASS is not affected whatsoever by this patch.
RE the flags you mentioned above, that might be useful if it's a ROM related matter.
This has saved my phone, seriously. I could NOT figure out why my phone refused to use GPS and not the cell towers in a certain spot where I live.
Using the ADB Google patch made my GPS work better than I have ever seen. Been two weeks now and has locked on within 5 secs, up to 9 (that I have seen) satellites .
Again ty for posting this.
I second that this is awesome!
I used the 3.x CWM Flashable Google Specific and now my phone (Samsung Blaze, CM10 11/25 nightly) gets a fix in about 2 seconds on 12 satellites inside the church where I work (3 foot thick granite walls)!
Thanks muchly!
One question- will I have to reflash this every time I flash a new nightly ROM ("dirty" flash), or will this stay until I do a full wipe?

Yes anytime u flash a new rom u have to reflash any mods uve flashed to change it the GPS.conf file is in your ROM and it says this in the OP if u would have read it
I'm not a Dev, I just flash alot!

Rules For Posting Questions:
Read the Notes Section first. I will refuse to answer questions that can be answered by some reading. If it is based upon something in the Notes Section, REFER TO THE NOTE when asking.
Answer the following questions: What ROM you are using?, What kernel are you using?, What GPS apps you have installed?, Where is your general location?, Are you using a case?, Has your GPS worked fine before?, Does it work fine with some apps and not others?, What else happened around the time your GPS stopped working? -AND- Have you reviewed the Notes Section?
DO NOT criticize the user of custom third-party NTP pools and xtra.bin data as dangerous. You obviously HAVE NOT read the Notes section OR reviewed the concurrent branch 2.x to discover it offers the standard NTP pool and Qualcomm-based xtra.bin server.
Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.
NOTES Section:
This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

Thanks Section
While this has gone a long distance since its inception, I want to still send thanks to Angeldeath for permitting me to take his early work and start tweaking it for HTC Inspire 4G users. This inevitably led to what we have here today.
Thank you to all those who joined and participate in the testing community. Without their help, I couldn't get enough data to know how well this works on different devices and in various regions of this planet we call Earth.
Thank you eagleeyetom, husky69, and tamagotono for their work in building an ADB pushing environment for Windows and for Linux respectively.

Notes and Info post
Post consolidation. I'm keeping this post open in case it's needed later.
Works well for me, especially considering it's overcast and I'm inside. Good work!
crypted said:
I will fluff this post out in due time.
Angeldeath made a great series of AGPS patches which essentially updated the gps.conf to speed up the locking process. However, those scripts are based upon regions for USA and no general support for North America.
I have created a patch that will allow for quick GPS locking across North America. I'll keep working on this as necessary to tweak it for our Inspire 4G devices.
HOWTO INSTALL:
1. Download the patch
2. Boot into CWR
3. Mount /system/ partiction
4. Flash the patch
5. Reboot

Thanks to Angeldeath for permitting me to take his work and start tweaking it for Inspire users across the continent.

AngelDeath already has a generic North America script in the OP of his thread (called North America.zip) which is what I used on a 2900 mile round trip to the Grand Canyon/Las Vegas with great results. Are you saying yours is better? If so, I'll give it a shot.

This is old. It doesn't have any of the truly necessary components. In his version terms, you're using version 1.0 which is defunct and was never updated. He is on version 1.2 with specific USA regions only for North America.
What I did was take relevant 1.1 and 1.2 pieces and combined that into a North America generic version instead of having to flash a new region every time I traveled three states away.
Also, I have the intention to keep testing and removing/adding chunks to get it more Inspire 4G friendly. As he said, his was for HD2 but works on other devices.
I just flashed this and it works just as well and locks just as fast as the other GPS fix. Biggest thing I did was to uninstall Google maps and then reinstall in again from the market.
Since then mine has locked each and everytime with in 5-20 seconds.
If you end up traveling, you will notice a difference especially if you're using scripts designed for a specific region. The point of this is to do away with the need for region-specific flashing when traveling. Also, I'm tweaking for our particular device while I go along.
GPS Fix App I have been working on
I have been collaborating with alienmind and AngelDeath and have come up with an app.
This will modify regions on the fly or restore stock settings or do all of the US territories.
@crypted I will pm you the link to the source to do what you like with it!
This won't require any terminal changes for regions as its a quick generic patch. It's good for basic users until angeldeath finishes his app. He and i thought this a good release to do.

Ahh I see. Very good, I will start using your fix! Based on the feedback in this thread, it sounds like you've got a winner. I've updated the GPS fix in my sig to reflect this thread instead of AngelDeath. Keep up the good work kind sir!
Wow this gps.conf file is great. I just locked onto 10 satellites with my case on. Normally I have to take my case off to be able to lock onto 10. Previously, with my case on I used to get 7-8 satellites, sometimes 9 but never 10. Good job crypted.
Glad to hear it's working. If anyone else has success with it, let us know. Shouldn't be many issues with this puppy...
Sent from my Inspire 4G using XDA App
This thing worked wonders for me. I've been having a hard time with my gps lately.. Having a hard time getting a lock and keeping it locked on. This caused me to get an instant lock. Thanks a ton!
Good deal. This is a great starting point for those wanting a one-time (per ROM flashing) fix.
However, flappjaxxx and Angeldeath are working on a GUI on-the-fly app to be released officially at some point down the line. Currently, it is based on region-specific gps.conf's. I think flappjaxxx will be using this gps.conf for a general North America patch in it.
My wife hated it when I said she'd have to change her GPS patch when she landed in Boston... She isn't techie and the thought of it not "just working" was problematic. My patch is a good fix to end that nagging nightmare!!!!
Edited the first two posts. I included an extra gps.conf to flash alongside the AT&T stock file. Also, I added results that have been observed.
This is great, pretty much sending me back to the drawing board with my app!
Great job. Just out of curiosity, this should cover Canada, Hawaii and Alaska as well?
My GPS has never worked better by the way!
It should work in Canada for sure. It should also work in Mexico and several other "North American" countries.
I'm not certain about Hawaii or Alaska and would need someone out there to test it. However, in theory it should work just fine.
In fact, it should work all over and not just in North America. But, the Inspire 4G is an AT&T phone which to me means it would typically be found only in North America unless someone's traveling abroad with one.
Someone with a DesireHD could flash this and try it in Europe or elsewhere and report back.

Wouldn't you need to tweak the file for European values?
Sent from A Van Down By The River!
Well, I'd want to know where I'm starting at if I were to do that. There isn't much point in tweaking files without knowing what the situation currently is and where it needs to go.
Again, this is really aimed at Inspire users at this point. But, we can do something for others if we get some results thrown this way.
Worked well for me - as good as (maybe a bit better than) AD's southeast conf file. Great fix!
AGPS Patch DesireHD 3.1 & 2.2 | GET BACK TO RAPID GPS LOCK, CAN LOCK ONTO MORE SATS
AGPS PATCH
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
List of officially supported devices is at the bottom of this post.
Use this if you're having GPS issues (unreliability, no functionality, etc.)
This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)
Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.
Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.
Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.

Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.
NOTES Section:
This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

Notes and Info post
Post #2 has been consolidated. Keeping this post open, though.
cool, I'd like to try out the DHD version when it comes out. I can't stand the GPS on my phone.
It's being tested now. Hope to release tomorrow or Thursday at the latest. Want all the beta opinions back first!
Sent from my Inspire 4G using XDA App
Officially released! Lot quicker beta tests! Everyone said it worked perfectly and gave great results.
Start flashing and have fun!
ROM devs use it!
One user has stated in a private message:
"I added your worldwide and north America configs to my app and they both work good for me but even though it is on the fly a reboot is required for best results. Also the first lock every time I change it takes a little while but after that first lock, every lock afterwards is almost instant"
Two ROM devs are baking this into their next releases.
FYI: I use Virtuous Unity 2.35 right now and it works perfectly.
works fine on my DHD with miui 1.9.2 and lordmod kernel
Hi,
i have no changes (CM7 lastest NB & LordMod 7.1 Kernel).

If you'd like to see if you will individually receive better results and if this patch is working, do this:
1. After you install the patch, reboot.
2. Install GPS Status from Android Market
3. Run GPS Status for about 5 minutes so the device can learn GPS satellites in your area.
4. Reboot again. Rerun GPS Status. It should be almost instant results...will be same with all apps.
Typically, I enable a GPS Status setting to keep the backlight on the whole time while testing. I like to see it actually working.
What people don't realize is that aGPS requires a bit of device learning to be very efficient.
Hi,
the behavior is like without the patch, a placebo effect.

As I have observed, there are some people who have great devices and great locations already. So, it won't be of help to everyone.
But for those of us who have the worst luck, it is a gold mine!
Thanks for trying it.
It is working perfect in Macedonia.. The www one.. I'm using MIUI and for the first time in months i have 7 sats in 5 secs.. i had 2-3 in 20min scan..
Thanks..

hi, i wellcome every effort on improving gps as i already did this myself (in my rom): you have there many settings i do not know and am curious on testing them.
but i also want to give out a waring about this one:
INTERMEDIATE_POS=1
me (being in germany) and some others (being in uk) had many trouble with this setting. when i had this i got a lock in 2sec but it wasn't a real lock. actually it wasn't locked to a signle satelite!
it caused only trobule. djscurf for example had regular gps drops during navigation until i removed it.
i just want to point out the experiences. if you post such stuff like a general soluttion you should only include general save options. maybe make that optional.
p.s. as far as i know ACCURACY_THRES does not make any sense without INTERMEDIATE_POS=1
It Works !!!!!
i am getting a quick location fix and an accurate one too!!!
Sorry, but what's the difference with the Angel Death patch here: http://forum.xda-developers.com/showpost.php?p=11342772&postcount=1 ?
Your patch looks like a copy of its /etc/gps.conf....
But I am maybe wrong...hope so !!??!!

It's heavily updated compare to regions vs continents vs this being worldwide unlike his.
He likes this one.
Oh and I removed internal bin usage as it slows the lock.
And more was and will be done.

well do so. but i already went through what you are
sadly the settings do not work worldwide the same. some are no problem but others can cause serious trouble depending on the region. it kinda sucks to debug that when it's running fine on your device
Since it works for most countries so far I can build a patch for duetchland only. Private message me suggestions and we can test together.

err, i have reprots of issues with that setting from germany, uk, spain, and sweden or norway (can't remember).
to be honest i very doubt that this setting works without flaws for most countries. and considering what i actually does it is not recommended anyway.
this setting tries to use different location ressources while you do not have enough gps satelites available. so it actually fakes a satelite lock! depending on your region and on your rom this could prevent the phone from searching further for satelites.
but anyway, everyone can try it. and if it works fine. i just wanted to note that here in case people get problems, to know what to look for.
edit: don't get me wrong. i wasn't asking for a patch for me, as i already have my on gps fix conf which till now has no problem reports anymore, since i removed that mentioned setting
AGPS Patch Desire S 3.1 & 2.2 | GET BACK TO RAPID GPS LOCK, CAN LOCK ONTO MORE SATS
AGPS PATCH
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
List of officially supported devices is at the bottom of this post.
Use this if you're having GPS issues (unreliability, no functionality, etc.)
This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)
Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.
Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.
Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.

I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

* I do not officially support all devices that this patch is known to work on at this time. You may private message me your success story for official support considerations.
Thanks Section
While this has gone a long distance since its inception, I want to still send thanks to Angeldeath for permitting me to take his early work and start tweaking it for HTC Inspire 4G users. This inevitably led to what we have here today.
Thank you to all those who joined and participate in the testing community. Without their help, I couldn't get enough data to know how well this works on different devices and in various regions of this planet we call Earth.
Thank you eagleeyetom, husky69, and tamagotono for their work in building an ADB pushing environment for Windows and for Linux respectively.
If you are happy with the patch and find this thread useful, please consider pressing the "Thanks" button on any of my posts on this thread. You may also consider rating this thread with five stars if you're satisfied. You may do so just below "Search This Thread" on the right-side at the top of this post. Donations are appreciated (See last NOTE)
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
Currently: this is a tentative supporting thread for my aGPS patch. Assuming more report success, I will start officially supporting this device.
Please let me know your success rates. Thus far, a few people have sent me messages and emails stating that this patch works great on this device.
As such, I'm thinking it would be good to provide this officially for this device.
This has been used on over 40 devices successfully. I don't offer official support for all devices. Rather, I offer official support once users convince me to do so for that particular device. That happened here.
Statistically, here is part of my post from mid-December on all official threads:
So, let me give you a general update directed to those 3.x trunk users:
My server has automatically generated an xtra.bin file for your GPS excitement 3,980 times since September 26th when the first beta went online to test it out.
My server attempts to build a new version every 30 minutes. Depending on what it can decypher from other xtra.bin sources, it provides a totally fresh xtra.bin approximately every 1.2 hours.
My server has served up over 500,000 xtra.bin files to users like you on XDA since v3.1 was released.
My server continues to provide a reliable NTP pool to v3.x users by directing your phones to a handful of RELIABLE and FAST-RESPONDING NTP servers around the world. This ensures you can travel and not have to switch NTP pools.

EPIC! Only 4 letters. It gets the signal and my position in a couple of seconds! Thanks crypted, many many many thanks!! You deserve more than my comments
I'm also getting gps fix in a few seconds on desire s, which didn't happen till now even with tweaked gps.conf... But one strange thing, gps status or locus can't see gps satellites, but they get gps fix...

Could be just a reading error between the legitimate reading and what's being shown by the app.
Are you getting an accurate location, say in Google Maps or other apps?
If not, try an Alternate build.
i had problem with very slow GPS fix on my ROM(older custom - virtuous ROM). im going to install MIUI ROM tomorrow and test it with and without this fix.
is there any user experience with MIUI ROMs?

All that I can recall with MUIU has been user reports that it's amazing on that ROM. Those were Inspire4G/DesireHD users though.
Working great with Reaper, always had to get a fix with gpsfix and be half way down the street before Runkeeper was ready, now it picks up as soon as I go out of the door.
Tested further and I'm getting wrong data. GPS fix in 2sec, but position somewhere in ocean near Africa instead of Europe. And it doesn't find right coordinates even after some time. I'll test another build as you suggested.

Installed 10 min ago. Seems to be working great, running Virtuous Quattro Beta 8.
Thanks!
I'm also using Virtuous Quattro (from this morning) and can report that it worked great for me - tested before flashing and had 1 satellite and no lock after 3 minutes (after using fasterfix for uk.ntp), after flashing the standard Google specific build I had 6 satellites showing in GPS Status and a lock within 20 seconds.
If I have time later I will test it with the CM9 build.
Thanks!!!!

The first series of questions were rather important. They were:
Can you be more specific?
What is it doing and not doing?
What are your surroundings like?
If removing the case does not work, the ROM your footer discusses is one that I feel was discussed in the Notes Section. It may be that you're suffering added injury from a ROM that doesn't have aGPS data properly enabled in its code. You could do a Nandroid backup, flash another ROM, and find out. Why do I say this ROM? Your footer states its a CM7-based ROM the Notes Section discusses how some CM7 builds were very, very badly made.

All are flashable via CWR (the Recovery flashing method) assuming your Recovery software is Clockwork Recovery or EXT4 Recovery.
If you want to flash it via Clockwork Mod, an App, you use the CWM verisons.
I think the guy is running the Endy ROM not cm7 as it says in his sig. I will try and test Endy 3.3 tomorrow maybe.
In the mean time I have to say this patch made a massive difference to me, I thought desire s GPS problems were hardware related but now my GPS works perfectly, it is fantastic, hopefully not just placebo due to clear cold weather here.
AGPS Patch HTC Desire 3.1 & 2.2 | | GET BACK TO RAPID GPS LOCK, CAN LOCK MORE SATS
AGPS PATCH
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
List of officially supported devices is at the bottom of this post.
Use this if you're having GPS issues (unreliability, no functionality, etc.)
This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)
Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.
Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.
Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.

Rules For Posting Questions:
Read the Notes Section first. I will refuse to answer questions that can be answered by some reading. If it is based upon something in the Notes Section, REFER TO THE NOTE when asking.
Answer the following questions: What ROM you are using?, What kernel are you using?, What GPS apps you have installed?, Where is your general location?, Are you using a case?, Has your GPS worked fine before?, Does it work fine with some apps and not others?, What else happened around the time your GPS stopped working? -AND- Have you reviewed the Notes Section?
DO NOT criticize the user of custom third-party NTP pools and xtra.bin data as dangerous. You obviously HAVE NOT read the Notes section OR reviewed the concurrent branch 2.x to discover it offers the standard NTP pool and Qualcomm-based xtra.bin server.
Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.
NOTES Section:
This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

Thanks Section
While this has gone a long distance since its inception, I want to still send thanks to Angeldeath for permitting me to take his early work and start tweaking it for HTC Inspire 4G users. This inevitably led to what we have here today.
Thank you to all those who joined and participate in the testing community. Without their help, I couldn't get enough data to know how well this works on different devices and in various regions of this planet we call Earth.
Thank you eagleeyetom, husky69, and tamagotono for their work in building an ADB pushing environment for Windows and for Linux respectively.

This is tentative support for this device. I have had a a number of people giving nothing but positive feedback for this device.
Let me know how it goes!
Using ICS 0.3.6 BETA I think it helped get a lock on GPS for navigation.
So thanks!

Those beta ICS builds are risky business for gps right now. I'd say a 80% success rate at this point just because of build issues...
Glad it seems to be working! I'm sure it'll be even better once the build get more finalized.

I just flashed the Google Specific CWM flashable zip. I've got the 5.0.2.0 CWM, running Mildwild 2.3 CM7.1 Nightly mod (S-OFF).
It seems like the GPS signal got a little bit more precise, I can't say it got ALOT better, but it did not get worse... I tested google maps before and after. The lock was faster and more precise than before the patch.
I'll have to test it at different locations (currently I'm just sitting at work) to get a clearer difference.
GREAT work by the way!
EDIT: it seems like I've gotten even faster lock after downloading assisted GPS data with the 'GPS status' app. Locks 95% correct position in only few secs!
It works pretty well on the Desire. Was going to add the patch and credits to my ROM, but had to pull my latest update for some other reasons.
Swyped on my Htc Desire running on Supernova Extreme - Gingerbread goodness with 2 GB of Internal memory
Yes, really works with Desire
I can connect at 10 sats in less than 10 seconds... nice!!
Thx
this patch should have been on the desire a long time ago, when i tried it about two weeks ago i was surprised to get a fix sitting in the middle of my living room in less than 1mn when it used to take 10mn even placed by my window thank you
I've been grabbing this from the p500 section for a while. Its no different per device, so its always worked on the desire. This is just at clone of the other thread.
Can confirm it works nicely on CM7.1 Nightlies and ICS.
Works perfect on my desire, fast and precise.
Thanks!

Which version did you use then on your ROM?
Wow! What a difference. Before I installed this, my maps and sportstracker app had trouble with gps. I was kind of "jumpy" in maps and sportstracker had trouble setting a start position. But now gps-lock is almost instant! Must admit I was a sceptic to gps scripts before. Now I'm proven wrong. I'm running Sandvoids ICS-rom. But had same issues on cm7.1.
Thanks for a great solution!

Can confirm that this is working on Desire. Installed Google Specific build as recommended, and it's working perfectly. GPS lock is definitely quicker and more accurate - I even managed to get a GPS lock from indoors, which my Desire never managed before.
I'm using Runnymede AIO v5.0.4 ROM, btw, in case anyone else using that ROM should want to try this out.
I had pretty good GPS coverage, (Melbourne Australia.) 8 of 12 sats and 6 metre accuracy with a hook up time of about 7 seconds. I flashed the google flashable file, this halved the hook up time and connects to 100% of days with an error as little as 3 metres.
HTC desire, great patch.

sounds obvious but tried a reboot or something? how about another GPS app?
sorry for my bad English
I don't know what different between 3.1 & 2.2?
is it mean my android version or just a patch version?

yup, rebooting changes nothing and as a matter of fact, it completely broke my data connection
AGPS PATCH
REVIEW THE WHOLE THREAD BEFORE POSTING QUESTIONS.
List of officially supported devices is at the bottom of this post.
Use this if you're having GPS issues (unreliability, no functionality, etc.)
This patch provides a worldwide solution to GPS issue for multiple devices. Using a general ROM without this has resulted in 10+ minutes of GPS delay. Also, GPS lock kept being lost. By using this patch, most people experience a GPS lock within 10 seconds (2 - 20 seconds range can be expected). Typically, a device using this patch will lock onto 7 - 9 satellites. Users have reported up to 11 satellites being locked at once. Without this patch, the average satellite count is 4.
HOWTO INSTALL: (Remember to make a backup. See Notes section for what this patch does.)
Method 1:
1. Download the "ADB Push Installer". This contains all versions for the latest build and old v1.3 versions.
2. Extract the files into a specific folder.
3. Plug your device into the computer and get it ready for adb pushing. Nothing out of the ordinary required.
4. Open the batch file called "ADB Installation Script - RUN THIS" if you use Windows. Otherwise, run the Linux SH script if you use Linux.
5. Select the version you want from the list.
6. Follow the prompts to reboot. You're done.
4. Review the NOTES section.
Method 2:
1. Download the patch
2. Copy all file(s)* into /etc/ of the system (not sd-card) using ES File Explorer, Root Explorer, or some other form. You must have SYSTEM set to Mounted and Root enabled. Check your explorer app's SETTINGS to do this.
**Files will be: gps.conf & SUPLROOTCERT -OR- only gps.conf for NO-SSL builds.**
3. Reboot the device
4. Review the NOTES section.
*Files are located in the /system/ folder of the ZIP. Do not copy the other directories or folders.
Method 3 (easiest if you use a compatible version of CWR or CWM)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
If you receive "(Status 0) Installation aborted" this Method will not work for you. Use one of the other methods.
5. Reboot the device
6. Review the NOTES section.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery. The Google CWM Flashable Build has binaries known to work with CWM on the X8. It may work on other devices. Please message me your success if you try and flash with recovery version and phone model as part of the message.

Rules For Posting Questions:
Read the Notes Section first. I will refuse to answer questions that can be answered by some reading. If it is based upon something in the Notes Section, REFER TO THE NOTE when asking.
Answer the following questions: What ROM you are using?, What kernel are you using?, What GPS apps you have installed?, Where is your general location?, Are you using a case?, Has your GPS worked fine before?, Does it work fine with some apps and not others?, What else happened around the time your GPS stopped working? -AND- Have you reviewed the Notes Section?
DO NOT criticize the user of custom third-party NTP pools and xtra.bin data as dangerous. You obviously HAVE NOT read the Notes section OR reviewed the concurrent branch 2.x to discover it offers the standard NTP pool and Qualcomm-based xtra.bin server.
Don't indulge yourself in ignornat posts. Provide information that may be relevant to helping. Simply stating "this stopped working" or "I can't get it to work" helps nothing and only annoys other readers AND those who may be willing to help you just will not do it.
NOTES Section:
This patch will work with virtually all Qualcomm, Android phones and has been reported to work with other chipsets as well. That means hundreds of devices could see a benefit to GPS performance from this patch.
This patch has various objectives to ensure stability and efficacy with GPS. Locally, the patch will replace your /system/etc/gps.conf and your /system/etc/suplrootcert if you have this file. You can compare the difference in what you have to this one to get an idea of all the changes. V3.1, onward, contains section descriptions for variables in use. Most notably, starting with v3.1 the aGPS Patch uses my own central NTP DNS pool and my own central xtra.bin server by default. The xtra.bin does have fallback servers should mine fail. But, that is very, VERY much an unlikely scenario. These two imperatives allow for better stability and speed by providing top-rated NTP servers and prime-routed network access to transmit the xtra.bin to your phone.
I recommend the GOOGLE BUILD of all trunks. However, you can use any build with any phone. You may have good luck with specific builds that do not fit your phone or carrier criteria. If you're curious, test it and see.
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
Remember, this has to be reflashed when you update or change ROMs.
Short patch history: The 1.x trunk only flashed a modified gps.conf file which relied solely on Qualcomm and NTP.ORG. Starting with 2.x, a gps.conf and a matching SUPLROOTCERT file for SUPL server authentication is included. The 3.x trunk offers the same as v2.x but adds better sourcing for NTP data and for the xtra.bin file; it utilizes my own server to do so.
Why toss out SSL?Whether or not you have a current SUPL certificate is questionable. Some have expired. Some will expire soon. Either way, the servers may provide SSL access without proper certificates depending upon configuration. That aside, I have found that SSL and secure communications over data networks slows the response times. I see no reason to use SSL for location information. If someone has a logger to obtain your location, SSL will not assist in stopping it. The bad app will continue to obtain your information by "stealing" it and you have more problems than a simple SSL-SUPL communications leak.
NO-SSL Builds will not have a SUPLROOTCERT because these builds do not use SSL. The SUPLROOTCERT is a certificate used for authentication of SSL connections. There is no need for this file for the GPS at this point.
IF you have issues with v2.x or v3.x, your ROM might require more variables. Try the old worldwide v1.3 version in this instance.
IF you still are facing issues, it might be that your GPS hardware is very much outdated. Try any "Alternate" build to see if this helps.
CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
Reports indicate that this patch DOES WORK with the next iteration of Android, Jelly Bean. This patch has worked from Android 2.2 (Froyo) up through Android 4.1 (Jelly Bean). Therefore, it works with all iterations on the market. I will remove support as soon as it is confirmed to NOT work with a new version of Android.
Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
Your phone "learns" about the individual GPS satellites. This is part of the aGPS design. Don't be surprised if the first time you use GPS Status that it takes 20+ seconds to "lock".
I have read a lot that indicates that it is best to let your GPS run using any application for a while to "learn" aGPS information. I let GPS Status run for about 10 minutes (it has an option to disable the screen timeout, which I do) each "first time" to learn. I say each because I test a lot of tweaks and fully reset/delete GPS cached information to start retesting.
Remember, this has to be reflashed when you update or change ROMs. Each ROM will have its own gps.conf, normally not suited to all devices.
I use GPS Status to test my signal strength. It isn't 100% accurate, but it gives a very good sense of how the GPS is performing.
If you're wondering why GPS is slow on certain apps? Or, you show up as on a street when you're 6 meters away from it? Well, those apps process GPS data differently which is out of anyone's control except the app developer. Certain apps will force your location to a street until you pass the app error threshold. Food for thought.
DO NOT USE ANY OTHER GPS FIXING APPS with this patch. If you do, and you still have problems, I cannot help you. A number of these Apps will overwrite what my patch does dynamically.
Variables are described starting in v3.0. Open up gps.conf in a text editor to read about what variable sections are for. It isn't in-depth, but should be enough to help you get a general understanding.
Still having weak GPS reception? Take your case off. Cases have been known to affect signal, though some argue against it. Personally, I get 3 more sat's when I remove my case.
There is a reported variable that can cause some GPS units not to work as well as it should with this patch. This is very odd as it's hit-and-miss and only seems to cause problems on less than 10% of handsets. This doesn't mean it screws up anything! It's possibly an older piece of GPS hardware incompatible with this variable. Have no fear, v1.2 will remove this variable for the worldwide version. This issue is more prone to occur in DHD.
Tried taking the battery out for 30 seconds? Some have reported that their phone required the battery to be removed. First, power off the device. Second, remove the battery for 30 seconds. Third, put it back in and give it a try. I cannot explain this except for possible cache clearing.
Some Inspire 4G and DHD devices have hardware problems. There is a known problem that the spring connectors to the GPS antenna sometimes are out of place or quit touching. http://forum.xda-developers.com/showthread.php?t=1101066 provides a video on self-repair.
An error in flashing this patch means that this method will not work for you. Use one of the other methods for flashing this patch. Don't ask why or for a fix. There are hundreds of variations of recovery systems and update binaries. I do not have the time or desire to support them all. This is why I describe other install methods. Reference error: E:Error in /sdcard/android apps/agps.patch.google.build.nossl.v3.1.zip (Status 0) Installation aborted.
Location is way off? Like, not near you at all? This means your GPS is not actually being used. Try the following to resolve it: Goto Settings -> Locations and disable ALL options. Reboot into recovery. Clear Cache and Dalvik Cache. Reboot normally. Go back to Settings -> Locations and only enable GPS. Reboot once more and try your GPS again. If this didn't work, did you read all of the Notes such as the one about the battery or RIL?
Donations: If you wonder why I asked for donations, it's simple. Users of v3.x are gaining extra, noticeable benefit over v2.x. This comes at a cost to someone. I pay the bills to provide a reliable data setup to transmit the xtra.bin data file and to provide the top NTP SERVERS in one DNS pool. To help keep this going, I just ask for the user to consider a donation. Nothing more, nothing less. Thank you for your consideration.

If you read the entire OP, the TF101 is a supported device....
@All A user requested I look into patching this device. Do not use the Prime's thread to download from. This is a unique patch for the TF101.
If all works, feel free toe donate.
ASUS never really repays, but they might end up ripping this one too and incorporating parts of it into another firmware update as they did for the Prime. Or, they just happily and coincidentally did that... Who knows. :laugh: I asked them for a free dock. I didn't get anything. Thanks ASUS for ripping people's work.
Worked extremely well for me. Got locked on to like 6 satellites.

good to see you brought your gps mod here!
i love it
I'm on RaymanFX 5.1.0 Jellybean ROM
This worked AMAZINGLY well. This was taking forever to get a satellite.. ANY satellite.. Literally took me 5 min to get a fix.. I flashed this and then loaded GPS essentials.. I had 11 Satellites almost immediately.. I had a fix by the time I made it to my back yard because I wanted to to see how quick it was back there..
I certainly will test this tomorrow as I use GPS on here ALL THE Time.. pretty much ever time I get in the car.. (I get lost easy. Don't judge me
Amazing patch.. Wow... HUGE improvement.

Thanks so much for this! I am using Revolver 4.2 as my daily driver. I was in the basement with no sats received before patching, and Revolver is very good with GPS. After the patch I got 6 sats in the basement and lock in under 10 secs.
WOW! AGPS on TF101 finally! :victory:
Method 3 works perfectly.
Working on SL101 too. Right now i got 2 satt
I'm on raymanFX's JB 5.1.0 ROM and flashed this along with making some permission changes in init.ventana.rc and now seeing 8 or so satellites right away and getting a fix in seconds. Thanks for the great job.

Works like a charm on TeamEOS #65!
I'm glad everyone's off to a good start.
You may notice a warmer backside with this in use. It's because the GPS is actually being used.
Thanks! Working on Megatron v1.1.6 / Guevor's 21.5 kernel. Will report back. :good:

I predicted that companies would get wiser and start providing properly built stock ROM's for GPS usage. That was incorrect. I'm willing to research and work with people to bring more devices into the fold.
There have been millions of downloads of my personal xtra.bin data and tens of millions of queries submitted through the DNS pool I maintain for Stratum II time servers. I lost track of the number of ROM's that have incorporated this patch. In fact, v3.x began 11 months ago and has brought worldwide help to the masses.
And remember, I don't have to release new versions of this patch locally because it has been so fine-tuned. But, I'm always working on the xtra.bin data almanac and the Stratum II time servers to keep this thing going strong.
To the few that have donated to support the many, thank you very much. If anyone would like to continue to support this project for growth in more devices and continual data provisioning, please consider donating as well.
