Gingervillain GPS problem

Hi,
I am having trouble with GPS on my desire since installing gingervillain. On both versions 1.4 and 1.5 GPS just doesn't seem to be working at all. I've tried a factory reset from the recovery menu and have tried re-applying the zip file but with no luck. GPS is enabled but I don't even get an icon on the status bar at the top when it is supposed to be searching for a signal.
Thanks,
Chris

Reach for the skies
Go outside of your house. Point your phone to the sky. Your position should should showing on your GPS.
Or it could be the program itself? Try different gps using apps like maps, facebook places etc etc.
Also do post what radio you're currently using on your phone. It could help people diagnose your problem better.

Tried outside and using gpstest off the market with no luck. I don't usually have any problem with gps inside my house anyway. I don't even get an icon in the status bar at the top it's like it's not working at all. And before anyone says yes it is switched on! My current version is:
32.49.00.32U_5.11.05.27
Any help would be much appreciated!

You must have the worlds strongest GPS in your desire. In normal ones, you need to be outside with the phone pretty much able to see the sky. On top of that, ideally it will need to be a clear sky.
Turn on GPS, open up Google Maps / your Navigation software (while outside). On my phone it only used to show the GPS icon in the task bar when a program was running that could use it.
Alternatively download GPS tools from the market (I forget the exact name).
If your GPS is indeed stuffed, take your phone back (if its under warrantee).
My GPS died on my phone. Completely. And before that it kept rebooting the phone. Had to take it back.

Same here too
Hi
very interested in this thread as my GPS worked fine until I installed Gingervillain 1.4 last week and then updating to 1.5 on Friday
Radio : 32.48.00.32U_5.11.05.14

I downgraded to GV 1.0 and my GPS was working ok again. I heard there was a known GPS problem fixed in GV 1.6 so I upgraded but the problem returned unfortunately. Any ideas?

Update the kernel with Villain set up, it cured my GPS problem.

GVChangelog:
Version 1.6:
* Fixed GPS problem (Thanks to CM Team)
+ kernel update defo works.

Hi,
Could you advise how I go about that? I thought the Kernel was updated as part of the gingervillain setup anyway?

Well I've had more fun with this! I just couldn't get GPS working on anything other than GV 1.0. I completely wiped my SD card and re-formatted the EXT3 partition. I then installed the stock RUU at which point GPS was predictably working. I then went through the flashing process of GV 1.6 and GPS was working this time. It was fine for a week or so but then the GPS stopped working again! I'm thinking it must be something to do with the dalvik cache now, that's the only reason I can think of for the GPS to stop working. I'm running out of patience with GV now so does anyone have suggestions for another stable 2.3 ROM I can move onto?
Thanks again,
Chris

[Q] No GPS Sat fix without Data Connection (aGPS)

Hi there,
first: sorry for the 1.000.000th thread about the GPS sat fix on the DEFY, but I have tried several ROMs now and still have not found the solution for my problem.
The problem is: my DEFY does not get a GPS sat fix when data connection is turned off (e.g. roaming or turned off manually). In GPS Status I see up to ten satellites (in grey or sometimes yellow colour) but even after hours I do not get the fix. When I turn on the data connection (either 3G or wifi) I get the fix in few seconds.
I have tried several ROMs now from Froyo, over Gingerbread to now CM7 RC0, but all show the same behaviour. I have recently downloaded the GPS fix from this thread: http://forum.xda-developers.com/showthread.php?t=953630 but it did not help at all.
I have deleted the /data/location folder, reseted the aGPS data several times, nothing got better.
I feel like sending the DEFY in for repair but then Motorola will check it with aGPS and send it back unrepaired because everything works.
So, if anybody has a solution or hint I woul appreciate it very much.
Thanks in advance...

HMM !
Same problem here

it is true, without agps data, very difficult to get fixed. That's why we need agps.

I have CM7, with GPS Monitor Free and AngelDeath's GPS fix 1.2.zip installed, I am able to get GPS lock in couple minutes without any Data (on fresh restart).
Give it a shot

GPS Monitor does not solve the problem
Hi there.
@teruyume
GPS Monitor did not help, it shows the same behaviour as GPS Status. Finds many satellites but does not fix!
Can anybody check if he has data in the folder /data/location ? I deleted it as stated in the FAQ for CM7 and the folder is not yet recreated. Might this be a hint?
I really cannot tell what the problem is: good reception (10 satellites) but no fix.

I have also been having trouble with GPS on the Defy. It will get a fix very quickly but moving the phone will cause it to lose its fix. It will go from having a lock on 8/10 sats to 0/1 to 4/5, etc. It won't hold the lock for long. I tried AngelDeath's GPS fix 1.2.zip and that helped speed up fixes, but it still drops the fix if the phone is moved at all.
@hartmuna
I made a backup of /data/location and then deleted its contents (not the folder itselft). Then I got no lock at all. I rebooted the phone and it automatically repopulated the folder and began performing the same as it did before. You might want to create the /data/location folder and just leave it blank, then reboot the phone and see if it will populate it again.
I also took a look at location.cfg and noticed a lot of settings in there that might be worth tweaking, but I have no idea what they all mean.

I found the data/location folder with terminal,don't know why it doesn't sure vida astro. deleted it again but that doesn't solve the problem.
I think I might give official gingerbread 2.3.4 a chance after the weekend. hopefully this will help?!?
Does anybody have experience with the leaked 2.3.4 and gps?
Sent from my MB525 using XDA App

I also had little problems to have the fix. And when I got (after several minutes) it loses during driving. The accuracy was too bad.
on CM7 rc1v2.

Anybody without GPS problems?
Hey guys, still no solution here. Tried every ROM out there.
One question: is anybody out there who does not have any problems with GPS fix without aGPS?
I am thinking of sending the DEFY in for repair...

With JBoogie3's blurry ginger rom I got 5 satellites used in fix in less than a minute (without internet). Try this rom before sending the DEFY in service.

same problem here, using last nighly and the problem still ocurrs, tried GPS-fix from angelofdeath but stil imprecise.
No solutions so far?
--
ive tried the GPS Monitor , he shows the lock, satellites, etc.. but, the gps with a "4 meters precision" put me on another street insted of mine, a mistake of ~50 meters (shows me on a paralel street instead of mine)

My standard Defy (still on Eclair) does fixes without Agps/data connection but after a trip of say 1000 km it can take up to 15 minutes to get a fix.
It also seems to help when I reset the Agps data first through GPS status (app).

GPS fix when not applying the UPDATE.ZIP
News from my side: I updated to CM 7 RC1v2 and this time did not apply the UPDATE.ZIP for my country described in this thread: http://forum.xda-developers.com/showthread.php?t=953630
And after few minutes I finally got a fix without aGPS data!
So my suspect is now the modified gps.conf. The original one is very short a has basically just the reference to the NTP and google aGPS server. The modified has far more lines that I have not yet studied in detail.
So, I will check the line of the gps.conf and try to find out what affects the GPS of the DEFY no to work...
Greetings from a happier DEFY user

That is good news. Would you be willing to copy/paste what is in your gps.conf file so that I can try updating mine without reflashing CM 7 and see if that solves my problem?

Sure, you will find the original.zip with the not modified gps.conf and then I installed the europe.zip from the above mentioned thread.
So far I am able to get a fix but for my patience it takes much too long. I am afraid that the GPS antenna of the DEFY is crappy.
Will do some more testing, any additional info is very welcome...

[Q] GPS fix problem in Cyanogen 7.1

Hello seems that a lot of people have this problem in 7.1 release. I read a lot about how to fix it but nothing works on my DHD, Should I downgrade to the previous stable release of Cyanogen? Can someone recommend a rom that is good out of the box? Thanks

The GPS problem usually happens when the ROM is not properly flashed or flashed without Wiping data properly, You can use FasterFix and GPS status aps from market to test and see if you get any GPS signal.
I'm using RCmiX 4.0 Gingerbread 2.35 with sense 3.5, the GPS lock works good in this, previously I was using ARHD 6.3.1 This rom was locking GPS under 5 seconds for me [ When I was outside and there was a clear sky view ].
If you are going for any of these two above ROM make sure you Wipe data properly / Factory Data Reset.

Maybe the antenna contacts are oxidized (another very common DHD issue).

I never managed to get a good gps signal on cm 7, or a good (non-grainy) camera. I use it daily when running, keeping track by cardiotrainer. Tried everything i could find. Switched to ARHD; problem solved. I hope it will be fixed some time, i liked cm.

Yeah the gps is a problem with cm7. You can usually use faster fix, gps status and gps fix to get a lock, but then if you are using it for navigation or similar gps tracking apps, the lock is lost after a few minutes.
The solution is to quickly switch the gps on and off whilst in the application that requires the lock and after having gained a lock, and then it should stay locked for the duration of your journey or whatever you are using it for.

Yet another uncommon GPS problem

Okay, this seems just another common GPS problem with a DHD. But I find it intriguing.
It happens to me since I bought the phone, second hand.
I've already made the mod to the antena (soldered wire) and use the AGPS Patch and FasterFix to choose the server. Nothing solved it.
So, when the GPS works, it works really fine, no abnormal signal loss, not too much lag.
Note that it only works fine when I turn data ON, so it can download agps info.
There comes a day when I turn data on, go outside, turn Sygic on (or other gps program), and no satellites at all. GPS Status indicates the same.
I can go for more than 15 minutes without gps fix. It can go for longer, but I don't have the patience. I reset the AGPS info with GPS Status and download a fresh one and the problem remains.
If I restart the phone, 99% of the times, it solves the problem.
Now, I found out that a program called Quick Reboot (https://play.google.com/store/apps/...Glub3NvZnQuYW5kcm9pZC5RdWlja1JlYm9vdEZyZWUiXQ) avoids me having to restart the phone. Plus, GPS Doctor is quite efficient too.
So, I have to run Quick Reboot, then GPS Doctor, then Sygic or other Nav Program. Not very handy, if you're already driving...
Now, what on earth is this?
Hardware seems fine, because it doesn't fail, for example in a 300 km trip. If it gets a fix, it stays on nicely.
It sounds a software problem, deep in the OS itself.
I'm on Android 2.3.7, CM 7.2, but tested this on various CM based roms, ICS, rooted OEM ROM and it behaves the same.
If anyone can help... or share experiences... Any devs?
Thanks

I dont think it is going to get any better than that. I have the same experience as well with ICS ROMs. However, some ROM's dont do it so often.

i have same issue on default rooted rom wwe3.12.405.1.....
it may be problem with some specific models or all od dhd series
and its very random and happens on trips mostly
agps /wifi/mobile data nothing fixes it
restart fixs issue instantly ...
once after restart gps gets fixed it works perfectly ...

I have this exact same problem, and I'll try your tip for using the Quick Reboot app.
I'd also recommend the app AGPS Injector which enables you to start GPS based apps e.g. navigation etc. 'via' AGPS injector. It automatically downloads AGPS info before starting the navigation app. You can even create homescreen shortcuts for navigator apps which do it all with one click. Perfect!
I'm going to try combining this with a Quick Reboot using Tasker, again so that it does it all with just one click. I'll report back if it works.

Yep, automated steps would be great, like:
auto data on / agps injector / auto data off / run gps program
or even
Run Quick Reboot / quit Quick Reboot / auto data on / agps injector / auto data off / run gps program
:silly:

Just got a total GPS blackout an hour ago, and the combination Quick Reboot + AGPS injector (bought the full version) didn't worked for me, despite 5 or 6 atempts.
Then gave up and just went for a try with Quick Reboot + GPS Doctor and got it working without rebooting. :good:

Sounds like I need to try GPS Doctor. I've had good success with AGPS Injector. For me, I spent ages trying to find an app which gave the same results as using the AGPS reset and download in GPS Test, and that did it. Maybe there's some regional variation.
Do those apps just force a download of the links in the gps.conf file?
Have created setups using Tasker which I'll try tomorrow. Also found the app Fast Reboot which does a similar thing to Quick Reboot, so I'll compare the two.
Sent from my HTC Desire HD using xda app-developers app

Yes, could be a regional variation.
Don't really know what the AGPS info download does.
I've used that Fast Reboot Pro program, but didn't do the trick for me.

Losing GPS signal while navigating

Hi,
I have a strange issue with my Gnex.
I used to run CM11 nightlies on my device, but I noticed that the device loses GPS signal while navigating (using Waze for example) and then it takes like 3-4 more minutes (if at all) to recover the signal.
So to test it, I flashed stock back (rom, recovery, kernel).
but I still have this issue. I cannot navigate 5 minutes straight without losing the GPS signal.
I tried to run GPSFix, but it didn't really help.
Any idea/suggestions what can I do?
thanks guys!

Is your device activated on a cell network? Gnex by default has assisted gps, so it needs a data connection to establish a fix. What you describe could happen as you leave Wi-Fi, have no signal, and it takes 3-4 minutes to grab the gps ephemeris data from satellites. Just a guess.
If this isn't your problem, have you tried using GPS status and toolbox app to Resetand redownload agps data?

Hey, thx for the reply.
Yes, I have a 3G connection and WIFI turned off.
I tried the toolbox, used it to reset data etc - but it didn't help

Well, the only way to truly know would be to flash a stock image and see if that works. If it doesn't, then you have a hardware problem.

Give GPS Test a go (search on Play store, I can't put external links here, it's the one from Chartcross Limited). It helped me a lot some time ago when I had your same problem.
