[Q] GPS problem - very strange

I have a GPS problem, and despite reading a number of the threads in the forum and trying the usual fixes (downloading GPS Status, clearing downloaded data, re-downloading A-GPS data, factory reset, upgrading to 2.3.3 etc...) I still figure out what's wrong.
Symptoms are:
I do have a GPS icon in the task bar in the apps where I would expect it appear
I never get a lock
Both GPS Status and GPS Test seem to indicate I have *no* signal from any sats
I am outside when I try this
aLogcat seesm to show no NMEA data, though I've never read a logcat entry for working GPS, so I'm guessing a bit here. It does show GPS start up and shutdown lines however
It didn't work in 1.84, when I downgraded, and it still doesn't work in 2.3.3 - seems to be version independant!
Does anyone have any bright ideas? It's really irritating. As a side note, the phone isn't rooted (as I forgot to S-off when I upgraded to 2.3.3) though it could be downgraded fairly easily if there was a good reason to do it...
Thanks!

If it has never worked and you have wiped the device, re-installed etc....
Then I would guess that it may be a defective unit...

1. are you running custom roms? if so which?
2. have you updated your radio and made sure that the RIL is matching?

1. Nope. The stock 2.3.3 RUU and before that the UK T-Mobile Stock 1.84 ROM.
2. Stock only, so standard RIL.

That is my fear. It did work when I first got it, but it now doesn't on any ROM. Unfortunately I can't quite work out what changed...
If this is the problem, does anyone know a way to get back on the T-Mobile official ROM so i can take it back to the shop?

Hi there, Your best bet would be to try and downgrade, root and flash a matched ROM, RIL & radio to retest. This happened to me a while back and this was the only thing that sorted it. CoreDroid has been particularly good for GPS on my DHD, hope this helps

Yeah - I tried the Coredroid rom - no dice. Think that confirms it's hardware. Back to stock and then back to the shop for this one.
I heard rumours that early DHDs were flaky for GPS. Guess that confirms it for me...

Had exactly the same problem with mine after using the gingerbread ROM from here http://forum.xda-developers.com/showthread.php?t=1056329
Are there different versions for different countries? Maybe this only works in the US or something? I'm guessing here!
Are there different stock ROMS for different countries/ networks? I didn't write down the version numbers before updating

GPS Partial Functionality Issue solution

My GPS stopped functioning in the correct manner on my Wildfire S A510a.
It may have been happening previous to my upgrade to Jikantaru XE Asian ROM or it may have happened after. I can't really say.
I tried everything including loading my base Bell Mobility rom and replacing the gps.conf file in system/etc to no avail.
It would work in google maps it seemed but in nothing else and applications like Wifi Finder, CoPilot Live, GPS Stats, etc simply wouldn't see the GPS and complain that it was off regardless of the toggle switch being on.
Also the GPS taskbar icon would not show.
I was running HBOOT-0.90.0000 and RADIO-7.46.36.14M from the stock bell rom.
I had an idea and first double checked that the stock RUU from Sasktel was for a GSM phone and it was.
I created a rom for it from the exe and flashed it to the phone, upgrading the HBOOT to 1.30.0000 and the RADIO to 7.47.36.19M.
When I booted into the stock Sasktel I had working GPS!
After doing so I reinstalled Custom recovery and rooted the phone again then restored my NANDROID backup of the XE rom and re-inserted the SD card that went with it.
The result?....
Working GPS again.
Hopefully this helps those with buggy or not working GPS.
------------------------------

I think I have a quite similar problem, but I don't know if I have an hardware or a software problem.
I read about fixing throu .conf modification, but my situation is that neither "Root System" software detect my gps hardware..
I was thinking about updating radio driver, but I don't understand if it's possible without flashing with a new rom or not..
If yes, where can I get the update.zip?
Now I have RADIO-7.46.35.08
Thanks a lot

I had the same problem after switching roms, google maps fine but no other gps apps that were installed had a gps fix. Tried everything to fix, in the end did a fresh install of navigation apps deleting the data folders then everything was fine again.
Maybe it needed different config files as i went from htc rom to cm7

[Q] BlackIce 1.27 GPS lost lock

Since I changed to BlackIce 1.27 from RcMix3D4.0 I have been able to get near instant GPS locks, but after 2-5mins I lose GPS in google navigation. If I restart the program it works again for 2-3mins...
Things I have tried:
Changing the GPS settings in IceTool & using GPS stats to download new gps data
Full wipe and fresh re-flash
Differnet RILs from Icetool
Flashing several different agps builds
What I would like to try:
Can I flash the gps.spade.so from one of my working ROMs (RCMix3D4.0, HTC Froyo, ARHD6.3.1) to BlackIce 1.27?
I am loving this ROM, I have my battery and performance just where I want them so I really don't want to change it (or change it as little as possible).
Thank you in advance for your help.

have you tryed flashing the gps and see if that helps you

this is a problem for every CM7 based roms.
the only way for it to lock all the way to ur destination is by...
(when GPS stops moving)
1. turn off GPS
2. turn on GPS

You are absolutely certain that you've turned on GPS in the location and security tab
in 'settings' ? I've had a similar issue with Blackice with Navigon, and it turned out that
i needed to turn on GPS for localisation on street level.
After that no more issues.

Problem is fixed but I'm not sure how.
I restored my RCMix3D 4.0 backup copied system/lib/hw/gps.spade.so to SD. Restored my Blackice 1.27 copied the file from the SD to the system/lib/hw.
It didn't work straight away so I re-flashed AGPS found on Xda (thank crypted). Now no loss at all, and quick lock times.
Strangely before multiple attempts of using AGPS did nothing..
My main initial question was really can I copy gps.spade.so across? What dose it do?

Again the GPS problem

Howdy,
So I'm another user having problems with GPS on my HTC Wildfire. I tried pretty much everyhing. Flashed all different radio versions via Recovery, fastboot and Android Flasher. Also I installed the agps patch. None of these solved my problem.
Before doing all this I had no GPS status bar icon at all. Now at least I have an icon showing me that he is constantly searching for GPS.
I also used GPS Test to clear and update AGPS but no luck.
Finally I tried several custom ROMS, from CM, to Splashmod and rempuzzle and all of them have this problem. So it's ROM independent.
What else can I try?

Fasterfix and gps essentials are the 2 apps that helped me fix my gps once.. and i had even used the agps patch by crypted for more accuracy

If you did all the above really clean - I mean with formatting/wiping/factory resets etc. it could also be a hardware problem in the end. But from my experience there are just a lot of pitfalls why solutions won't work.
The fact that you didn't get the icon show up before but now it does looks to me that it's not a hardware problem. My suggestion would be to reflash either the radio and the ROM again - but as clean as possible.
- look into "The Complete Wildfire Index" thread (in "General") pick the radio in the middle and flash that first
- do a clean wipe of at least the system partition, cache and dalvik-cache (I also do "format system" and sometimes a "wipe all/factory reset" to be sure and it couldn't hurt to wipe data also - your decision)
- flash the ROM you want to use
- flash gapps
- reboot and look what it does (this most likely won't do at that point)
- flash the newest of the 3 radios afterwards and see if this helps
--- Edit --- to flash two different radios is a dirty trick to remove leftovers or problems because wiping or formatting doesn't touch the radio --- EDIT ---
For testing GPS I suggest GPS Status from the market (best tool in my opinion). You could delete ags data as well with it.
The agps patch (I'm using it too) is just for optimization (to get faster responses) - it won't help if your GPS doesn't work at all.

Hello guys,
I finally resolved the issue and realised that GPS was working all the time well. However, I always tried to search for a signal inside a building in front of my computer and was not aware of the fact that the signal might be too weak to be received from within inside...:silly:
Anyway, the flashing method apparently did the trick!
Cheers

[Q] GPS not working after new ROM(s)

Hi,
I wanted to use my old HTC One V as a bike computer and remote for my Panasonic camera, but the GPS wont work anymore! All GPS apps/tools show the GPS as enabled, but they cant find any satellites, not even after hours of searching. I tried the following steps to resolve the problem to no avail:
- Went back to stock, relocked the phone, uninstalled the old TWRP recovery, installed two different RUUs, but the problem persisted, everything else works
- Went back to fully modded, installed four different ROMs, newest TWRP recovery, unlocked the phone, etc., still no GPS
- I tried the Ignorance v5 ROM, stock RUU, and CM11, 12 and 13 (everytime I used the correct kernel/boot.img)
- The phone didn't have a SIM-card, so I tried my working SIM, but still no GPS
- GPS was working when the phone was stock and also the Ignorance v5 ROM. After I lent it to a friend, I made a factory reset and wanted to try newer ROMs, thats when the GPS stopped working.
Now my questions are:
- Is there a way to view debug information on the phone, if there is an error? Like more infos, then the standard GPS apps give me.
- Should I check the installed radio and does an RUU overwrite the radio? Does the radio even interface with the GPS hardware?
- Maybe someone has a ROM-Backup with working GPS that I can try to put on my device?
- Is there a way to test the GPS antenna? WLAN, bluetooth and GSM works normal.
I will upload a screenshot of the fastboot screen ASAP.
Kind Regards
