Odd GPS issues

OK, so I've dug around the forums and have yet to really find anyone who had a similar issue and wasn't able to fix it with either FasterFix or GPSStatus so thought I'd start a new thread. If anyone knows this answer and knows it's in another thread then let me know and I'll shut this one down...
Anyways, the issue in a nutshell is that Maps refuses to work without "Wireless Networks" being checked (it throws up an error that tells me to turn on My Locations or to turn on either "Wireless Networks" or "GPS satellites" even though GPS sats is checked in the settings) and even then the accuracy is horrible (on tower-based, which is more or less to be expected since it's a triangulation, I believe), Navigation/Locations will both get a location but it appears to be "Wireless Network" based, GPSStatus shows a max of only 3/3 sats even outside on a clear day but no other app sees those even those 3 sats. I basically think my GPS chip is locked up. (Is that even possible?)
The GPS issues started one night on CoreDroid's V5.0 after working for quite some time on CD's various builds, including working on 5.0, so I flashed up to 5.1 and still no-go. Wiped everything, reflashed 5.1 and still nothing. Moved over to RCMixHD 5.9 and it still acts up. It used to be that I could uncheck "Wireless Networks" and it would just bounce off of the GPS sats but now nothing seems to see the chip. I've wiped everything, reflashed numerous times, flashed a new radio (the latest Mar leaked GB radio), gone inside, outside, around the house, around the town, etc etc etc, cleared the Maps cache, uninstalled/reinstalled Maps, reinstalled Locations several times, reset the GPS state with GPS Status, redownloaded the GPS data w/ GPS Status, changed out the gps.spade.so file in CoreDroid 5.0/1 with one from the Inspire Dev Forum (I think, may have been General) that modded files based off of FasterFix files that were supposed to fix the GPS if FasterFix doesnt (the files worked for a whole one test...then everything quit working right again) and I've reset the NTP to North America's server via FasterFix and STILL nothing. I'm getting rather frustrated at this point and any help would be appreciated. Thanks guys!

How about flashing back to stock Rom?
Sent from my calculator

What would the advantage be? I mean I've already flashed different ROMs and gotten the same issue so part of me doesn't care to flash another couple of times but another part of me wonders why it'd help any since it's just going to be overwritten when I flash back to RC or any other custom. Will flashing to stock somehow reset the GPS. I know flashing to stock is generally one of the first suggestions but I've always wondered how it actually helps. Guess I'm off to hunt down the stock on my computer while I wonder lol...thanks

Did you use RUU to get back to stock Rom and radio? RUU does more than just flash the Rom. It flashes the radio to stock. Only reason I'm saying this is cause someone else had Gps issues and when they went to stock unrooted, everything worked as it should.

Do a forum search for inspire RUU. Should come up.

Awesome, thanks. I was unaware that the Inspire had an RUU. Well, most RUU's I've run across have been packaged into a program like ODIN but I think I can do the RUU manually via ADB. Hopefully they have a program out, though. Think all my stock stuff has been done via ADB and the Hack Kit so I'll dig around for an all-in-one program. Thanks!

Sadness...no such luck even on RUU stock.

Just curious, what method did you use to do this?
Is this the same one you used?

I have been having similar GPS issues on my stock Inspire. After a long HTC customer service call, I was advised to do a factory reset on the phone. Voila, the problem appears to be solved. I now get 8 or 9 satellites and lock in about 30 seconds. Also, after this reset, my battery life is much better. So, I am not sure what bug I eliminated in the factory reset, but I accomplished something. What would affect both battery and GPS? I know this is not the same as for a rooted phone, but perhaps there is some connection. By the way, just what SNR do users with solid GPS performance get on GPS Test? I never get SNR over 25 on any satellite, whether indoors or out...

HtcOmega,
I helped another person with an inspire, so maybe it might work for you too, Try the link in my sig and see if replacing the gps.conf with one of mine may help you. It has been very successful so far, it might help with your dilema as well. And if your going to ask whats different about mine then fasterfix app, the answer is alot.
Let me know.

I was having the same issue as HtcOmega and decided check out your link. I must say that my GPS is working as it should now. Takes at most 30 seconds for a lock without the case on. I flashed the north america zip instead of choosing the north east version. Is there any reason why you wanted people to choose their specific region?

Primarily the reason is I broke up the USA into 6 regions and made a script for 62+ individual countries because I am not using the generic ntp servers from the pool, these are ntp servers specifically for that location, and by narrowing down the location and not using a general ntp it should make lock times faster. If you read the thread for the most part quick reading you will see that the NA script is made primarily for people who travel to many places frequently and do not want to keep changing scripts, as well as people in the common wealth countries would use the NA script.
I am currently testing out 1.2 with a handful of beta testers to see if the new script can be a little more consistent, there are new commands in the new script, which is phase one at least for the HD2 since the HD2 is a prt and lacks the support for true agps.

Google Maps can't get lock on GPS after upagrading to CM 7.0.2

Hello,
I upgraded to CM 7.0.2 and can't get lock on GPS when using google maps navigator. I tried using GPS Status and reseting GPS data, using MSL Reader does not work since Inspire is not CDMA which reader seems to work with. GPS Status and GPS Test work at locating GPS satellites.
Did anyone have the same issue and found fix for this?
thanks!

Try being less of a jerk please.
While those scripts do help some, it's not the end all be all fix.

I was in your situation... somewhere along my happy flashing i lost my gps capabilities. I decided on cm7 but still had a broken gps. I flashed that script using cwm and now my gps is perfect, better than any gps from my previous phones. I do suggest downloading gps status after you flash those scripts. It'll download some agps data and hopefully your gps will lock on flawlessly from than on. Good luck.

Thanks guys! Will try using the script.

For the person that said he flashed the script and it worked flawlessly on CM7, which one did you actually flash? South East or North America...
I was in the same position before with CM7 and GPS acting up....did both of those and nothing changed really...
now i just freshly re-rooted my phone after having my parachute savior of going back to ATT STOCK completely...(saved it since i know if all else fails i can always go back and go back to the drawing board)...
I want to carefully chose my roms and also i would like to go back to radio that i originally had...so that's my next step.

[Q] GPS not working

I have an inspire 4g on Att. running android 4.0.4, redemption 1.1. i have tried all the different gps installs in rom tools for att, generic and stock gps and rebooted after each change. however my phone still will not connect to a gps sat. it will not see any and therefore cannot lock. anyone have any info that may be of any help.

Slow
I'm running Android 4.0.4 with the C&C ICS rom and although my gps works I've noticed that it is very slow when trying to find my location in things such as Maps. Is there something to flash or update to get it working/improve performance?

Either hardware fault or improper aGPS settings.

Bad gps on SynergyROM

Hey guys is me again lol. I just flashed the newest SynergyROM update ( 1.7 ) and my gps doesnt show me at the correct location. It keeps moving around my area, mostly 3 to 4 blocks away from me. i didnt mind that however when i go on navigation, the directions are incorrect due to the location being wrong. Is there a fix for this? I did a full wipe before installing just like instruction on the thread and i installed it after going back to stock and rooting.

Have you tried the Synergy thread? A lot has been discussed about GPS issues.

i did check it and tried going to stock and then back to synergy and still same issue.
Edit: I just started reading many of the comments and i guess i will wait for the next update. Battery life is too good to quit the rom.
Thanks for the reply

From what I read about it, and I've been following the thread because I use Synergy, its possible that it is a hardware issue. Or its possible that you need to Odin back to stock and start over. I've been flashing and reflashing Synergy since 1.0 (or maybe it was 1.1) and haven't had much in the way of issues, GPS works fine.
I'm on one of the nightlies right now, have you tried using the current nightly? Not sure what else I can suggest, I'm pretty new to it all really.

hope this gets fixed

If you flash back to stock does GPS work fine
Ive seen a few posts that gps doesnt work and they have been told flash back then flash rom, but my question is when back to stock does gps work then? if not maybe its the phone its self
I have not had any problems even VZW can find me if i turn gps off

This may not the best route, but it has worked for me so far:
I'm also on v1.7 (Odined back to stock unrooted; rooted via GS3_debugfs-root_r2; CWM 6.0.1.0; clean v1.7 install with data/cache/dalvik wipes) and this is what I did when I initially flashed and noticed GPS locking issues:
1. Toggled GPS
2. Went outside & launched GPS Test
3. Updated AGPS
4. Once the "In Use" # of satellites in GPS Test showed 2 or more I launched Google maps and got an immediate lock.
Since the initial flashing of v1.7 when I have GPS locking issues:
1. Toggle GPS
2. Go outside and launch GPS Test.
3. Once the "In Use" # of satellites in GPS Test show 2 or more I launch Google maps. I usually then get an immediate lock. I also verify with Waze.
I noticed that if I keep GPS on, then I don't have to launch GPS Test to get a lock. However, if I turn GPS off and toggle it back on right before I need it, my GPS lock takes longer. If I'm waiting past 30 secs for a lock, I just launch GPS Test and wait for the "In Use" number to populate before going back to Maps or Waze

Is your Wifi on? Sounds strange but the same thing was happening to me and it said turn the Wifi on and I locked in after being 3 blocks off

I actually got my gps problem fixed. I odin back to root66 and did a factory reset there and ran maps, the gps was working fine. Then i upgraded to the newest synergy and gps is working fine as well. I did a full wipe before going to synergy.

[Q] GPS locks, then gets stuck - Lollipop/CM12 issue?

Using Google Maps with Lollipop CM12...Has anyone had the issue where they can get a GPS lock, Google even gives you the ETA of your destination, but as you drive, you lose your lock and Maps gets stuck - thinking you're on a random side street nearby while you're actually moving on course? I am using Location in high accuracy mode. I'm running the official 4.4.4 firmware posted by @Tigerstown too. Never had this issue before. Ideas anyone? Thanks!

I have had this issue before. Not on cm cause I don't run that. I'm trying to think of what ROM this was on...I tried all the lock tricks I know. My maps did the same thing as yours. Only choice I had was not to run that ROM..if you get it figured out but I don't know what you can do I didn't try let me know

It looks a lot like this problem : http://forum.xda-developers.com/google-nexus-5/help/gps-dropping-signal-ota-lollipop-update-t2951515
(Also reported in AOSP : https://code.google.com/p/android/issues/detail?id=81140 )
Sadly it seems this problem has not yet been solved/acknowledged by Google...

Well that sucks, I'm looking for a fix to it. Preferably a fix that does not involve returning to stock, then reflashing to CM after I get a lock, and hoping the planets were lined up perfectly.

This issue has been fixed for me for quite some time now. Which device and ROM are u running? And are you 110% sure that you're using the latest firmware?

I got it fixed. Try though, and yes I'm absolutely positive that the firmware is up to date. It happened because I was messaging with a room that used a f2fs /system position, and CM needed it to be ext4, so it was formatted before installing. I just installed a known functional ROM, then installed CM with /system left as is. No Isadora since aside from CM using a newer recovery, and forcing it on us now.
