Defy CM7 RC1.5 GPS Problem

Hi There
I've been using CM7 RC1.5 for at least a week. Everything works smoothly, much better than the crappy stock ROM does, except for the GPS.
Whenever I try to locate myself with Google Maps by GPS, the GPS fails to locate. The GPS is fully functional with the stock ROM and I have no idea what the problem really is.

I haven't tried RC1.5 yet, but I was having the same problem with CM7 RC1. I tried everything and couldn't get the GPS to work. Finally I flashed a nightly build of CM7 (8/17) and it started working again. I would start there and see if you can't reverse engineer the problem.

Use this fix : http://forum.xda-developers.com/showthread.php?t=953630
Flash it in custom recovery
Basically all it does is edit /etc/gps.conf to include time servers for your region from here http://www.pool.ntp.org/en/

Thanks
The issue has been fixed

a similar problem with the GPS was not fixed pravarth's link
i flashed CM 7.1.0 stable and the device just doesn't get my location using the GPS.
Apps like GPS Status and GPS Test plus give no results on GPS satellites found .
Any ideas ?
PS : it's defiantly a ROM problem. On Miui, GPS tracking was working. The only difference was that on MIUI, GPS apps will often reboot my phone.
Thanks.

GPS problem is fixed in my case after choosing my region from the Baseband Switcher.
Now i get some results in GPS status.
Orange Romania worked for me after choosing Central Europe, Hong Kong, Taiwan, Arabia, France, nordic 3.4.x, UK 4.5.1-85

My GPS problem is persisting.
I`m using CM7 RC 1.5, applied the patch for my country, changed the baseband still no luck.. .
If someone can help me, i`ll appreciate it. Thank you in advance.
Edit: I`v solved my problem using this http://forum.xda-developers.com/showpost.php?p=18777808&postcount=1150

[FIX][20-NOV] Omega v33.1 and v33.2 (+stockXXELK4) GPS fix

**Symptom**
Loosing GPS fix on I9300 after 20sec-20mins on latest XXELK4 / Omega v33.1+v33.2 ROM mainly in case of 1st lock on more then >10 satellites.
**Possible solution**
Flash in CWM this one for fixing the GPS issue on Omega v33.2 (tested on 33.1 and was working).
**How it's done**
I simply took all related GPS files from previous Omega version where GPS was working fine and replaced them.
**How to install**
Simply via CWM and perform eventually permission fix after (just for case)
**Result**
Before I was loosing all GPS satellites in 20-30sec, now it looks stable, locking up to 15(17max) satellites
**Which solution I tried before and didn't help**
FasterGPS, setting the parameters
Reflashing Omega on Omega (noWipe)
Reseting aGPS data, downloading new one
Installing another modem, now I'm on I9300DDDLJ1
Turning off GPS, Google location, location via Wifi, rebooting phone and re-enabling again.
Wiping cache + Dalvik-cache + Fixing permissions (after this step I had to reflash no-Wipe the ROM)
Flashing another kernels - stock, GalaxiSih, now I'm on Boeffla-Kernel
**Warning**
Be sure you have nandroid backup and/or reflash no-wipe in case of troubles (wasn't however observing any issues by myself so far).
**Where you can use it ?**
Tested so far on Omega v33.1, confirmed working on Omega v33.2 as well including some other XXELK4 stock/custom based ROMs
Not needed for Omega >=v33.3 or patched stock ROM XXELK4
**Just press THANKS if it worked**
Thanks to Omegas Team.

All you need to do to fix is flash a different kernel

Incorrect. Lots of people running 4.1.2 on various kernels and still facing the same problem. Myself included having tried 3 different kernels.

Not helping. Already tried. This is nearly annoying like the hello hello bug. Not all got it and every phone needs a different fix.
Edit: Tried the fix before and don't work for me. Can't get no fix after flashing but it could also related that I got a custom kernel installed. You say you on custom kernel too. Did you flashed the video fix?

No, just Omega, custom Kernel and then this simple fix. Wait for the 1st fix, also be connected to data/Wifi. Best for testing is GPS test.
*sorry* I just flashed also another modem just prior to that fix, see 1st post...however when I flashed different modem before I was trying to fix GPS issue, it didn't help at all

Don't know for sure but think maybe the video fix who install the old libs brake GPS again but I'm not sure. As I wrote in omega thread. After dirty flash it works perfect even with custom kernel and after installing the video fix it brake down again.

It's working so far.
I haven't flashed fix video but installed siyah so sooner or later I'll need the video fix.
I'll let you know how it goes.

Tried all what you have said you had tried and also no luck - still having GPS problems.
Installed the fix.
Before installation, using Waze, I used to get a fix within 5 seconds, and then I used to lose the signal after 3-5 Mins. max.
After installation - got a fix same within ~5 secs, and I kept it on for about 10 mins and I had no signal loss.
I will try it further on my way home (about 20-30 min drive) and post results.
Thanks alot - hope this might just do it!
***EDIT***
Drove 20-25 mins home - all working fine.
Will do more testing tomorrow, but looks like this is the fix, for me anyhow.
Big thanks!

Work for me.
This fix work for me. Test during 40 min of navigation .I´m on Omega 33.1 with video fix and Kernel Perseus 26.1
Will test again on the end of the day.

Small report:
Today morning I use GPS (Waze and Be On Road) to navigate to my work (15km).
Lost signal every 3 - 5 minutes. Strange.
In my work I flash your fix.
Navigate (Be On Road) approximately 15km to customer and 15km to work. Working absolutely good.
Thank you.
I will test later much more and report again.
Update1: On the way home from work gps navigation (Be On Road) work like a charm. I am lucky
Update2: Today on way from home to work, working very well. Thank you. Now I vote for YES

Hi my friend. But suddenly your fix work here. Did another full wipe. Installed my usual stuff and got no fix. Then I thought I try again your zip and it works for now. Will test how long but really hope that's it.

Not sure i tried this one, but just flashed it and will try in about 2 hours and will report back.

For me it's working now.. I'm on Omega 33.2 and latest Siyah
tapatalked via SGS3 on OMEGA and Motomoto00

Oke, just had my 25 minutes drive.
Flashed your zip before went on the road, double checked that Use wireless networks was enabled again, this afternoon i disabled it and gps worked again.
And from work to home, not one single drop off gps noticed using Sygic.
Also watched carefully to Sygics speed meter and it was corresponding with the speed i actually drove, not going from 30 to 100 i saw yesterday before gps broke down.
Looks your file did it for me.

[Q] codefireX - SR12 GPS issue

Hi,
i install code fire SR12, It's very faster than the SR6, but i have an issue with the GPS.
It can't use Google Maps or Navigation.
I have :
12.65.60.29U_26.14.04.28_M
I did the AGPS PATCH too
Are they something to test more?

Have you tried all suggestions in third post of the cfX thread?
A few tips there, and links to give more detailed explanations. Do them all, until you get it working.

Hi guy's,
Thanks for your help SSamiK.
I tried
- Flashing A-GPS patch ==> not working
- GPS Status&Toolbox ==> not working
- Test with another Radio ==> it's WORKING
I change my radio from 12.65.60.29U_26.14.04.28_M to 12.69.60.29_26.17.14.11_M
i used this link http://forum.xda-developers.com/showpost.php?p=9891581&postcount=3
i find here in jellytime developpement code that we have to use the last version of radio 12.69.60.29_26.17.14.11_M
For me in Europe the radio 12.69.60.29_26.17.14.11_M work fine with CodeFireX SR12

Radio Update Worked Finally

CM12 Official Nightly Lollipop GPS Not working.

I am running the latest nightly from https://download.cyanogenmod.org/?device=t0lte
I have TWRP 2.8.5.0 installed as my recovery.
In order to test your GPS you need to change the following setting. (Otherwise clever stuff happens and your location is guessed from wifi/cell tower locations)
Menu==>Settings==>Location==>Mode==>Device Only
My problem is that none of the nightlies seem to have a working GPS. This can be seen by installing one of the many GPS Test Apps (GPS Test, GPS Status& Toolbox), they will never get a fix.
Is there any known fix for this?

I faced the same problem with you,it seems lost some api about GPS.
But I don't know how to fix it.
I hope one day CM team can fix it as fast as possible

So I havent found anything yet but it seems that some of the unofficial CM12 ROMs have got working GPS (Device Only)
http://forum.xda-developers.com/galaxy-note-2/development-n7105/rom-unofficial-build-linaro-t2997775
I have no clue how they have done it though.

Fixed the GPS by applying the ROM fix in this thread

GPS Fix
http://forum.xda-developers.com/moto-g/help/guide-fix-gps-cm12-t3084705

In this case the fix has now been added to the CM Official Nightly.
It was related to a missing driver which is what my previous link pointed to.

Signal drop on CM13

Hi, i'm using Temasek's CM13 and i noticed the cellular network lost its signal every day. Is there any way to fix/prevent it? Or solve it when it drops signal. I'm fixing it by turn on airplane mode, restart, turn off airplane mode, restart, turn on airplane mode, then off again (long procedure), so if there is any way to fix it faster, plz tell me.
My phone: Z008, Temasek CM13, OctoDex kernel 5.0

Please dont open new threads for old bugs.
Qick search on Temasek (or CM13) ROM thread.

I know my question have been asked for hundreds times, but i see the changelog of the rom says "on 9th July fixed signal lost issue", but i'm on the newest build (10th July, Z008), so it have to be fixed, but i'm still have that issue

Understand.
But the right thing to do is to report on apropriated thread - the official CM thread - and, in this case, the issue will only be solved when the asus blobs are fully merged into CM kernel.

It only solves signal drop issues for several people. For me, flashing or not doesn't have any impact if Indosat SIM card is active: Signal could suddenly loss and I need to take a full reboot to recover.
