[GPS Scripts][APR.25.2011 1.2 FINAL RELEASED!] GPS Notice of Error Post#1 EAST COAST

15.July.2011: Please follow this link: GPS Mis-Naming & GPS Lock Times EAST COAST ONLY.
An error was caught by Firemanj79 that could affect GPS Lock times for people living on the East Coast.
Greetings All,
I would like some people to beta test something I have been working on in the HD2 forum, which I think will benefit MOST people. I cant guarantee it will work for everyone. I started this project in the HD2 forum because the GPS drivers are not complete with agps support, and made a new gps script to aide in helping lock times to be quicker, and to lock onto more sats. Which has been successful.
I have an Aria that I had laying around and my daughter wanted to use, so I decided to let her use it, which I just rooted, flashed a stock att rom, and upped the radio to current, then installed gps status and tried testing the gps. I was getting 2 sats with difficulty, after I replaced the gps.conf file, my lock time shortened very quickly and instantly had locks to 9 sats.
So even though I know the file is universal and just about any android phone can use this, I would like if people could try my file and post results here to see if it helps people with trouble with their GPS and even if you dont have trouble, if you just want to try it.
Most from what I see only get a lock to 4 or 5 sats, seems 9-12 is unheard of. The files are in CWR so flashing it through recovery should not be a problem. If you want you can just pull the gps.conf file from the zip and adb push the file. The link obviously is in my Signature, but just to make it easy:
Instantaneous GPS Fixation CWR v1.2 USA & INTERNATIONAL COMPLETED!
Of course by the name, I have made files for the USA broken down into 6 regions, and I also made files for 62 countries.
If it works for you, please hit the Thanks button, do not fill the posts up with Thanks thats what the mods made a button for. If you feel the urge to donate, please feel free coffee does wonders.
But I am more then happy just to give back to XDA with what I can. If any Dev's wish to use any of my files, you may do so as long as credit is given where credit is due.
1.2 has been released!

Thanks for this post...and obviously, the work you've done. I travel 100%; GPS lock speed is something I notice on a weekly basis... new city... leaving airport rental car facility... "which way to the hotel" ?
Keep up the good work.

Tested with Gene's 2.2.2 and CM7 Stable + Ladios' kernel + old gps libs - Very fast lock times on both.
Lock times from a reboot & data cleared
CM7 - 12 sec.
2.2.2 - 9 sec.
Smooth reboot after flashing on 2.2.2
CM7 after flashing restarted 5 times from the HTC white screen (I thought it was going to boot loop but it didn't) and booted fine.

I received an error code 0 when trying to flash the North America file to my Aria. This usually means that the edify update binary is not correct. I then replaced it with the binary from the current CM7 and it started to flash, but then errored out with a "Mounting SYSTEM mount () expects 4 args. got 3.
Looking at the script it should probably be:
mount("yaffs2", "MTD", "system", "/system");
instead of mount("MTD", "system", "/system");
Maybe it is just me, so maybe someone else can try North America on their Aria.

Got a double post. Anyways, after an initial lock in under 1 minute indoors, subsequent locks are under 5 seconds. I am located in Costa Rica.

I flashed the newer updates 3.22.11 from further down in his thread. It has the US broken down into regions. Maybe those work better???

Dunno, I flashed the North America because I am in Costa Rica. I looked at the newer ones and the update-script is formatted the same. Maybe I am chasing something that wasn't broke, but all I know is that the first one without mods gave me an error and wouldn't flash.

my location started to jump across the city and back

I dont know if it makes any difference, but these are obviously for an HD2, maybe the scripts are different in the Aria? Honestly they all work with CWR in HD2, but if you are having trouble like I said, you can just take the gps.conf file from the zip, and either adb push the file, or mount the system in CWR and copy the file over. I copied the file over in CWR mounting the system through droid explorer.

drowningchild,
Thats a bit odd, try rebooting and see if that might help, I know the file gets read at the very beginning of boot up during the white htc screen. But it shouldnt make you bounce all over the place.

Works great for me!!! the gps now locks in 10 sec aprox! i use the South America script (im in Argentina), I have to push via adb... the flashable file dot work in my Aria... Exelent work!!

fedealf,
There is a specific zip for Argentina that I made. I am going to be update the post shortly and link all the ones that are not in the main post. but in case you want to try Argentina here is the link Argentina.zip

Dude this is great. INSTANT Gps fix. Running stable CM7 with Ladios Kernel.
I don't even have to run this RC4 'fix'. I love you.
Edit : tried to use navigation and it said I was on a different road than I was on.
Getting locks, but not where my location is. Reset AGPS using gps status.
Edit 2 : Went to navigation and it locked on my house this time. I rebooted. Shows correct direction and road.
Thanks bud

Would love to test if I could download it, keeps telling timed out. southmidwest

Plumberchuck,
Since you said south mid west I wasnt sure what you were referring to, so I added both to this post, let me know how it works for you.
All the files are hosted on my webserver, I dont know why some have trouble, I can tell you that for some reason it will not allow you to download the file if you are trying with the phone, it has to be from a computer, dont know why though.

You rock man! for argentina to, thank you very much!! later i tell you how it works.

dead links?

^^^^ you've got to download from a pc. Not your phone.
Sent from my Liberty using XDA Premium App

Sorry area lost power today, try again, everything is back and running.

Thank you, I was on my comp and could download everything but the link, don't know why am loading zip tonight will let you know tomorrow how it works for me.

[Trick] Speed Up Satelite Fix for GPS on Android

Guys,
I decided to write this because a lot of us here still facing GPS issue on their device. I almost give up on my HTC Desire HD because of the GPS problem. After I find this trick, now I realized that HTC devices have one of the most brilliant GPS hardware. It always get a location lock within 5 - 15 seconds.
This trick not only to speedup the satelite fixing. Some also found that it increase the reception (strong signal even during cloudy, light raining, and inside building's window). I am one of this case .
Here is the tricks. It is tested on HTC desire HD, SGSII, and speculated to work on most Android device (Please note that it is in sequential order):
Requirements:
Rooted Device
File Manager: e.g. Root Explorer
1. Searching for NTP server information
Go to http://www.pool.ntp.org/en/
At the right side of webpage, there is "Active Servers". Go in and look for the setting of your 1)region and 2)country
For example, one's region is Europe then you write down the NTP server for that: 0.europe.pool.ntp.org; 1.europe.pool.ntp.org; 2.europe.pool.ntp.org; 3.europe.pool.ntp.org
Then the servers for your country from the list down there and click the link(Example: Switzerland — ch.pool.ntp.org; 0.ch.pool.ntp.org; 1.ch.pool.ntp.org; 2.ch.pool.ntp.org; 3.ch.pool.ntp.org
The "Italic" words are the information you need to jot down for later use
3. Modify the gps.conf file (Most Crucial Stage)
Copy the codes in grey box (in first post) to a notepad, then change the extension name from .txt to .conf then copy to your phone
Use file manager to copy to this location: /etc/gps.conf and replace the original gps.conf
Open and Edit the gps.conf using rootexplorer or others file managers
Change the COUNTRY and REGION in following lines with the info you got from the website just now. Keep other values unchange unless you know what it is. Example of REGION such as NorthAmerica, Asia, Africa, Europe.
Your new gps.conf should look as below:
NTP_SERVER=0.COUNTRY.pool.ntp.org
NTP_SERVER=1.COUNTRY.pool.ntp.org
NTP_SERVER=2.COUNTRY.pool.ntp.org
NTP_SERVER=3.COUNTRY.pool.ntp.org
NTP_SERVER=0.REGION.pool.ntp.org
NTP_SERVER=1.REGION.pool.ntp.org
NTP_SERVER=2.REGION.pool.ntp.org
NTP_SERVER=3.REGION.pool.ntp.org
NTP_SERVER=COUNTRY.pool.ntp.org <-This is changed from the top line to here. It may works better if we put it here.

Tool available in market for free, please donate so developers are encouraged for better release in the future[/B]
Open app> tools> manage A-GPS state>Reset
Open app> tools> manage A-GPS state>Download
Optional restart device (not compulsory)
Use GPS status to start fixing satelites
Your satelite fixing speed should VERY FAST now
After get a successul GPS Lock, open your GPS applications and use like normal (e.g. Copilot, Sygic, or TomTom)
Extra Suggestion: Please make sure your GPS is enabled before your device is turnoff or restart. It won't actually use GPS unless you open map-related app or google.com.
CAUTION!!!: DO NOT use fasterfix after this. It will overwrite all the content in gps.conf​

[Update: 17 August 2012]
Sometime even my phone won't work consistently. It won't able to get fix within 30seconds everytime. And i found this tool can be very very help to make sure my agps 95% up to date and thus has the best performance.
The tool is called "Leo AGPS Injector" developed by Tytung. Please click thanks or consider donation on the following post to thanks for the developer - Tytung. I have no credit at all for this tool. I just share it.
Here is the link http://forum.xda-developers.com/showpost.php?p=16384028&postcount=1907
Step to use the tool:
Install and place the widget on your home screen
Ensure your GPS setting is on
Make sure you're conencted to Internet / Mobile data
Press on the widget to inject AGPS data
Now you're good to go. The internet can be turn-off now. and your gps should work well
Note: I noticed once i connect to a big internet network (such as my university internet network). My GPS won't work anymore.
This is what i do to make it back to normal:
Connect to Mobile data (3G) and use "Leo GPS injector"
if it is still not working, i switch to airplane mode and back to normal mode again, then repeat step 1
And i notice, it works better if you use mobile internet, rather than fixed source internet at home. This is just what i feel, not necessary true.
Please post your feedback to let others know it works on your device model
Please click "Thanks" if you feel this post is useful for you​

Thank you very much for this post.
Fortunately I've never had a GPS issue on my DHD, but still I would love to "fully" understand your solution ...
If it is possible, can you please explain what exactly these settings do, or can you post some links where I can find some extra info regarding these settings and their "ïmpact" for my DHD ..

Do you want me to put permissions on a settings selection in the "Settings - Location" options ?
Sorry if my question is unclear, but I'm a bit puzzled by that part of your solution post.
AGAIN !! Thanks for the nice post and great effort .. Much appreciated !!

Should we be removing extra lines at the top if we have less NTP servers available? For example, Canada only has 1, so should I be copying that multiple times or just put it in once?

Yes. Remove the extra lines if you need less servers for your place

Hi Wacco,
That's rw--r--r things was an typo mistake, I will removed it. Thanks for pointing it out.
Unfortunately, a friend of mine send the file to me. He said all the descriptions are as per in the comment (#). I think he said he extracted from the firmware of a GPS system in my country. And i wasn't expert in GPS things, I afraid I'm not the right person to answer you Perhaps some experts may drop by and asnwer you question soon. I also wanted to know the details too

The app faster fix will not work for me in my sgs2 it just shows a black screen is this step needed or can i miss it out?

Please ignore my nooby type post before i needed to upgrade my busybox duhh

This works like a a champ. Best GPS lock time I've ever had!
Thanks a bunch.

Tried it on my Motorola Atrix and it didn't make an improvement but it wasn't a detriment as well. Granted, my office is a cable head end with satellites and ****loads of cable equipment which may interfere.
I'm sure it will probably help if anything though. Thanks for the tips!

Yes. The surrounding is very influential to the working of GPS.
My car's windows are tinted with silver chrome tint. I nearly cannot get a single satellite fix inside my car.
But the GPS just work like charms in my bro's car with normal tints.
This trick mainly is to help users with slow GPS fix, it is not a magic
THe main idea is hope that before users mess with the risky fix (e.g. messing with hardware: physically adjust the antenna), they can try these low-risk tweak. So that they won't broke their device.
And most of the time, it is software issue, rather than hardware

What roll does Fix it Actually play?
What roll does Fix it Actually play since we are replacing the GPS.conf file anyways?
About to try on a Toshiba THRiVE Tablet will let you know if it helps...
UPDATE: I think it made it REALLY WORSE...2 mins and no fix

when we upgrade our ROM (for ex from ARHD 5.2.6 to ARHD 5.2.7) , do we need to redo this ? or we only redo it if we fully wipe before ROM install ?
cheers

If you look at the comments in the script it's self explanatory.

Hi mate, I really not sure cuz I always do a clean flash. Maybe you can share with us when you upgrade your ROM. And a quick way is to save your gps.confirm file in sdcard. Then replace the one after flash (if the flashing revert it back to normal).

If you willing, please keep and try for few more days (keep your agps data updated via downloading tru gps status frequently). Cuz one of my friend also didn't work immediately but a few days after that.

Am i missing something..i run fixit.apk, that is an installed program...not a script...then i replace a bunch of text in gps.conf...again not a script...what im asking is what does fixit.apk do...i could replace the gps.conf file without fixit.apk

Hm... In my tweak, the first step is to download, install, and run Fasterfix (not Fixit, i not sure whether they did the same thing or not). But i didn't mentioned that it is optional to use the faster fix or not. I suggest to run, to be a safer step. Yes, it will write the gps.conf (but currently not sure whether the app change other things or not until i verify with the app dev). So i just keep the whole process that i gone through to make my gps works

AOSP GPS Issue - Discussing which Sense rom to flash FROM.

So I recently decided to switch to ThunderShed 1.5 from Infected Eternity, and the GPS was not working whatsoever. I spent the better half of the weekend flashing different sense roms to see what would yield a working GPS. (Performing the GPS lock in sense, then flashing immediately to ThunderShed)
I think I have achieved somewhat of a successful case, so I decided to share in case anybody was wondering.
Case 1:
Infected Eternity Sense 3.5 -> Thundershed
No working GPS, icon does not appear even after extended time.
Case 2:
Stock .5 and Thunderstick -> Thundershed
Random GPS fixes. Sometimes it would work, sometimes it doesn't. Takes a random amount of time before deciding to work.
Case 3:
Finally, BAMF Forever 1.10/1.11 -> Thundershed
First lock takes a little bit (with no icon), but after the first lock, GPS works after that without reboot. (Locking varies between position and conditions)
So there you have it. It took me a while to find a working BAMF Forever to flash from, but you can find it on their team BAMF website.
Does anybody have any other experience with this?
Edit: Also, I'm using the latest leaked radios from OpenMobile and was always using bundled kernels...

I've had luck flashing from both stock .9 and Bamf SoaB to Liquid 3.2 and getting a GPS fix. Regardless of the rom the first lock seems to always take a while, but after that it seemed quite a bit quicker.
Edit: This is all using the .9 OTA radios and kernel (except for the Imoseyon LeanKernel in Liquid)

gps.conf
Instead of flashing different Sense roms replace /system/etc/gps.conf with the stock file or run FasterFix from the play store, which is just as good.
The one that comes with ThunderShed 1.5 points to non-functional NTP servers and missing xtra.bin files.

[Q] Slow GPS fix

Hello ,
I have a problem with my optimus 3d p920 .
It seems to get a very slow GPS fix .
I been searching alot but not realy found a fix .
Can someone point me in the right direction ?
i am on XPlay3D v2.0 rom with baseband l6260_modem_sic_01.1042.00 accoring to system info of phone
.

Im having the same issue

I think it depends on the ROM settings and maybe even the build.prop file in /system/
I am using Prometheus ROM v1.4 with stock+ kernal and my GPS locks VERY quickly. I usually leave GPS enabled anyways which probably helps once its locked the first time.
I have been on other roms that takes FOREVER to lock onto GPS as well and if I recall correctly, I think some of Meemos roms had that problemf or me too.
Sorry I can't be much more help than that. My suggestion: try other roms and see how they do.

What I use and I must say with success is a little apk called GPSFix.I start gps module from drawer, then start the gps fix, wait for about three secs till morr sattelites are shown then start my navigation program. Doing so in about 20 secs maximum, usually I get a 12 secs, I do get a fix.Anyway for me it works.

Where do you get that ?

Check your NTP setting in:
system/etc/gps.conf
In the line:
NTP_SERVER=(you must set your closest location)
And change SUPL_PORT= to 7275
Search for your closest NTP server in www.pool.ntp.org

I found out that the GPS fix speed is ROM and/or settings dependent. For example, all the Froyo stock roms were much faster to get a GPS fix (10-20sec) comparing with the Gingerbread stock roms (45-90sec). The same applies to custom roms as well.
I would not recommend getting the GpsFix as suggested because it comes with tones of spam as you can see on the comments. Instead you could use the much more popular and with many additional features GPS Status & Toolbox.
Also if you don't want to change your NTP settings manually as suggested above, you could do it with an app called FasterFix.
I have to say though that even if the above apps could help decrease a few seconds from your GPS fix time, the most important for that is the ROM that you are using. I think it's unacceptable for LG to break the GPS fix on GB roms (together with other things) while it was working perfectly fast on Froyo.
I just made a comparison of O3D with the 6 times cheaper ZTE Blade with the app GPS Status. For O3D it took 75sec to fix and it fixed on 5/7 satellites. ZTE Blade made a fix in 11sec on 12/13 satellites!

Hello ,
Flashed XBSA V21E P920 and it seems much better , bt im gonna test more .
Thx for the help .

You might be right even if the spam that I get is not generated by GPSFix. But even so we're talking about offline navigation, so there won't be any data connection so no spam.Even so you can use some ad blocker program, starting from rom toolbox lite, just to name one.

Check your NTP setting in:
system/etc/gps.conf
In the line:
NTP_SERVER=(you must set your closest location)
And change SUPL_PORT= to 7275

Yet Another GPS Fix

This may or may not be "snake oil," but it may help the GPS lock time.
The attached secgps.conf adds the following lines to the "stock" version.
Code:
NTP_SERVER=north-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
It includes an NTP server (for North America, if you're elsewhere, you can check the NTP Pool page) and XTRA servers. I don't know if the SGS4G proprietary driver (and no, Aries doesn't have an open source one that I know of) can take advantage of them, but at least the information is there now.
After removing the .txt extension, install as
/system/etc/vendor/samsung-agps/secgps.conf
Ownership is root:root
Permissions are 644
The location may be different for anything except Team Acid's current ICS ROMs
(This was posted prior to the release of the Aries kernel)
These ideas came from the Crespo4G secgps.conf

I think (think) that this GPS fix only works for people who lives in America I really dunno if this would work in other continents still thanks jeffsf
Edit: nvm didnt saw your hiperlink

This seems to work well for me. I don't have hard evidence but it seems like it's working better.
