Can't get GPS to work...on CM7 - myTouch 4G Q&A, Help & Troubleshooting

All,
Been on CM7 since build 32 and cannot get GPS to work. I believe I got it to work twice. I have tried everything from deleting the SPL lines from gps.conf, and downloaded GPS Status and nothing worked. I have gone as far as to doing wipes between nightly builds fresh install and still nothing. It's driving me crazy.
Any info would be great! Thanks!

I had the same issue. What actually worked for me was I just let it sit for twenty minutes searching for GPS and eventually it found it on it's own and has been working with no issue since. Although when it did find it at first it had me in a location jumping from street to street but it eventually locked into my position.

This should be moved to the Q&A sub forum. I'll request that.
------------
For me, the usual process has been to enable the GPS and then reboot as I'm heading out the door to the car. Reboots seem to have been the key.
But on #39, even that has not worked. There were a number of GPS related patches yesterday, so I'm hopeful that the nightly was built before all of the commits hit the source tree and #40 will fix it.
I've asked in the main thread about it. Its possible others with #39 have functioning GPS, and the restore procedure I use after installation may have hosed something.
Symptom: GPS Status shows no sats, and never receives sat information. A-GPS reset/reload has no impact.

Ok, so you saying install #40 and see what happens? I'm still on #38, guess I'll update tonight.
Thanks!

Yes, according to the CM7 nightly thread tonights build should address the GPS issues people are seeing. Try it out.

[FIX]GPS Dropout Fix

If you're having problems with your GPS continually dropping out, particularly on the new Gingerbread release, try downloading GPS Status from the App Market and reset your AGPS data.
In GPS Status,
hit [Menu],
then [Tools],
[Manage A-GPS state],
[Reset],
Optionally you can [Download] for new A-GPS data
I tried it on CM7 nightly 36 and apparently I'm getting quicker locks.
[Update 01]
Apparently, that first method works for some, but not all. There is a second method, but it requires you to be on a Sense Rom (Stock HTC based). I'll add it here. More people say that this works better, but I was reluctant since I was already on an AOSP Rom (CM7), so I would have to flash back to a Sense Rom.
You will need your MSL code for your phone
Using a Sense Rom,
go into the Phone Dialer,
and Dial ##GPSCLRX# (##4772579#)
(Reboot)
Here is the original post by SantinoInc: GPS Fix (GPS Reset)
Were you driving? That has been stated numerous times to only work while not moving. Or to only work for a short period. I did the ##GPSCLRX# fix and have not had to worry since. Getting down to 6m accurate whole driving.

Please forgive my ignorance, but how do you type letters on the dialer? I tried using the number key with those letters (works out to ##4772579#) which didn't work. So I feel appropriately humbled. How does one run that code, please?
GPS Status works fine, but I only use it for this; so, if I can not have another app on my phone that would be great.
Thank you for your time.

I was also having GPS problems with the CM7 ROMs. I restored a Sense ROM and ran the fix using the dialer, then restored my CM7 ROM and my GPS worked perfectly. However, I just flashed to the lated MIUI ROM and now my GPS is taking a long time to lock. Had maps open for 10min on my drive into work before it locked on. It did eventaully lock but it doesn't seem to work as well as it use to. Wondering if this is a MIUI thing??
Im in Japan on a seasonal stanby for three months
so i dont have service, just paying 9$ a month
Im trying the ##GPSCLRX# on a sense rom so i can switch over to a 2.3.3 rom
I put in my MSL and did the reboot
i opened maps and have been waiting for around 30 mins for a lock
and NOOO success
It just will not lock!
Is it because im on Seasonal standby?? and not using phone service
My GPS is on and im using wireless networks turned on
its still moving around not locking
ahhhh!!!
My gps would not lock and the icon would just disappear after a few minutes. I was able to get it to lock using the steps for 'GPS Status' app, but I had to do it again the next day. But after closing out of all the apps, the gps icon was still there and would not go away.
There was no need to start another thread on the GPS fix; it's been posted for quite awhile now.

No, even from Japan with no service you should be able to get a lock. In fact you should be able to get a lock from anywhere with NO data at all, but you do need a data connection to download the map data and see a map overlay of where you are (obviously), and also you need data in order to download the GPS "cheat sheet" A-GPS data. But it sounds like you have other problems, perhaps your ##GPSCLRX# code didn't take. Did you reboot all the way through? try it three times in a row and make sure that you do NOT use any app that can access the GPS device after the last reset before flashing an AOSP rom. That includes the market, the web browser, maps, latitude, navigation, etc. After the second time you reset it, try shutting it off entirely in the control panels.
GPS fixed on CM7
Hello,
I tried everything said in forums about gps fix but I had no gps on CM7 nightly and had no problems in sense roms. I do not remember where I found someone recommending a kernel for gps fix and another people said ##GPSCLRX# solution should be apply 3 times in a row to be effective, so I tried both, I have gps working perfect on CM7 but I cannot say which method was the solution.
This is what I did:
- Made a backup, of course.
- In Ginger-AleV2 (sense rom) I dialed ##GPSCLRX#, then enter my MSL, reboot automatically. Returning from boot I repeated this step other 2 times.
- Go to recovery (I have Amon-RA 2.3) and restored my CM7 nightly #86, then I flashed #87 (in same session, just wipe cache & dalvik before), then flashed GoDm0de-v8 kernel (in same session too).
- Reboot and checked GPS, working perfect since more than 8 hours.

after you do the gpsclrx command and it reboots you NEED to open the google maps or similar software, let it lock and track for a few minutes, then reboot and nandroid back to cm7
Just for giggles, leave your GPS on when you flash CM7. That was what finally worked for me.

GPS Aids - Need feedbacks

Hello there!
I'm getting reports about "GPS Aids" not working with Vibrants. Some users with Galaxy S phones and GPS drivers from Vibrant got the same problem.
The app it's on the market. So the first test will be install it and tell me if it is working or not.
Regards...
Original post at > http://forum.xda-developers.com/showthread.php?t=955395
Went onto market, searched for and downloaded the app.
It wouldn't download the GPS aids... it kept saying "connection detected" then it was unable to downlaod the data.
When I enabled the root option (brute force) it finally worked.
Testing GPS now, will update/edit with results.
Maybe you should try the Themes and apps section, not trying to be a mod Just saying it might help get you more testers.
Okey.. I have a user in the spanish forum with a Vibrant. And the native mode it's working fine for him. Will ask for ROM version. Thankyou Bignjuicyjc
@Bignjuicyjc are you using a different GPS driver from stock? Like the captivate driver?
Hello I tested it out the other day. currently am on trigger v2.1 (froyo). Installed it, popped it on with default settings and tried out gps test app. Normally I eventually see 11 sats in my area Minneapolis,MN USA. With aids I saw 3 and never locked on.
So went into the setting of gps aids and deleted gps data and forced it this time around. Same deal: takes 3x as long to find any satalites, finds 1/4 the amount of sats and never locks on. In google maps/navigation my locations was off by almost 2 miles. Rebooted and deleted gps data and tried gps test again. Same results.
Had to delete data, uninstall the app and restart my phone before I could lock onto anything again. Some people in the vibrant community say this has helped them alot. And then theres people like me where it made it worse. Hope that helps.

Install/Uninstall don't change nothing. I think that it is something related to the GPS driver using in ROM. Do you know if your ROM is using a captivate driver? Or other different from stock?

I too am using Trigger... but V2.5 which if I'm not mistaken uses Masters GPS fix.
But then again, I also used Samsung GPS restore app from the market AFTER i had flashed Trigger.
It seems since using Gps Aids the GPS is "seeing" more birds but not locking on to any.
Will continue to test.
does this work on Samsung Galaxy 3 GT-I5800?
Does this GPS Aids works for my Samsung Galaxy 3 GT-I5800 mobile phone?
This phone is Android 2.1.
This phone's GPS currently does not function well. It is very slow and take forever to get any GPS reading, is any.
If I to apply your GPS Aids to my phone and it is not the correct patch for this phone, is there anyway I can go back to the original firmware?
Thank you.
I loaded it last week on my Vibrant, it works.......... No Big Great difference since I have Masters GPS fix previously installed, but it does work and the locks are about 10 sec faster
Tried it and installed and downloaded properly on first try. Didn't see much difference at first, but when I went to visit friends in the middle of nowhere, I got locks when my gf's captivate couldn't. It didn't show up in the market for her captivate, but I sent the apk by email, installed it and it also got the gps to lock in. So here's two votes for it working.

Flash it thru Clockwork Recovery
I've had mixed results. It works for some customer roms and not others. It is confirmed working on Bionix and Auxura, but I didn't have good results with Trigger for some reason. Thanks for the app. I'm locking on 6/13 satellites indoors and 11/13 outdoors.
Feedback: Last week. I installed GPS Aids on my Vibrant and it downloaded the file and appeared to work quite well. But, 2 days ago, I developed a problem with something not related, and had to do a factory reset. Since the reset, I can not download the file. I keep getting a messaging saying it can't download Xtra and to try again later.

Somehow my GPS stopped working

Had been running 7.02 and then updated to 7.03 the other day. I had an occasion to use the GPS yesterday, and it refuses to get a gps lock. GPS Status show 11 sats, yet it never locks. I did the old CM7 > CM6 > CM7 trick and it will lock once, and only once. (this was after turning GPS off and then back on)
Any clues?

You definitely dont need to do the cm6 fix, that was only for if your gps wouldnt turn on at all. It didnt have anything to do with it getting a lock or not.
Using gps status: Menu>Tools>Manage A-GPS state>Reset.
Menu>Tools>Manage A-GPS state>Download.
Also, do you have your Data connection turned on? Or wifi? If you try to get a lock without one of those turned on it can take quite a while. And try to get your lock outdoors and without moving until you get your initial lock.
If that doesnt do it for you I would first suggest re-flashing a fresh download of 7.0.3.
And finally, which radio are you running? The originaly 2.1 or the updated 2.2 radio?

Thanks for the response:
I have tried the A-GPS reset and data, without any help.
This fails with either WiFi on or off and out and about ( in car)
GPS was working on my phone with 7.02, but in between the last time I used it, I had installed Tasker and updated the radio (I was getting lots of dropped calls on my morning route) and upgraded to 7.0.3. Restoring my Nandroid 7.0.2 does not resolve the issue, so I do not believe that it is a 7.0.3 thing. I guess I can back the radio update out and see if that was it, not sure if that made any reception difference anyway.
Thanks,

yea try reverting the radio image and let us know if that fixes your issue. Ive seen other posts from people having issues with the newer radio image. Ive not personally had any issues but every piece of hardware is different.
How do you revert back radio images? I have this problem too sometimes. I just exit GPS Test and start it up again and it finally finds my position after I was already connected to satellites.

This is a typical Q&A thread, which is in the wrong forum. I'll move this to General.
I'm also having GPS issues but mine when I'm using it if I make a turn the arrow will stay facing the same direction (if I'm facing north and turn east it still faces north) but if I'm at a stop light sometimes it fixes itself I'm using cm7 rc4 I had to the original cm6 back to cm7 GPS fix. It work for along time flawlessly nvr had any issue till now. I haven't updated the radio either

GPS never works after Froyo

hi all.
Ever since I went from Froyo to Gingerbread-based ROMs (and since then to ICS) my GPS has never worked.
AngryGPS doesn't find a single sattelite after 15 minutes, it just like the GPS is dead.
All ROMs I try claim to have a good working GPS, however none actually works.
The GPS lock icon, which should be blinking, is there but not blinking.
Since most people claim to have a working GPS with ICS, could it be a problem with the phone itself?
(I always try the GPS after a reboot)
Thanks for your help.
Been having the same issue, i have tried tens of solutions and flashed tens of fixes, i even opened it to try to fix it and it still doesnt work like its suppose to. Google maps never get my accurate location, its usuallly about a mile off, mapquest however is able to give me turn by turn navigation albeit its often late in its guidance. Very frustrating.

Well, I do use ICS passion right now and I did use eugene's kernel at some point in the past (maybe with MIUI, don't exactly remember).
Anyway none of them had working GPS.
My phone was manufactured at July 2010. Could it be some old revision with GPS problems? Although I did apply the hardware fix back when I was using 2.2, which did help back then.
This is why I'm sadly back onto 2.2. GPS still sucks but better than on GB.
I did everything possible to get GPS to work on GB. I've done the hardware fix, I've flashed everything possible, and the only time it worked was after each reboot, and only then temporarily.
Agree 100%
GPS in ICS is flaky. It usually works right after reboot then it's a gamble. A few times it would work for me for a day, sometimes second run of GPS Test doesn't bring GPS icon up at all.
To make things worse, external GPS support is equally bad. I have a feeling it uses the same driver/daemon.
Obviously there's either not-so-compatible driver in kernel or the API is broken.

Try a app from the market called GPS Aids. It does help for me.

Unfortunately the "donate" version does nothing but ask for donations.
I would kick in something if it actually worked, but not on speculation.
GPS at least sort of worked with stock (whatever was on the phone when I got it used) but never at all with any CM build, including with various fixes applied. It at least sort of worked with Onecosmic's ICSSGS, at least once, maybe with some fix or other applied.
A quick update : Turns out, I need two conditions for the GPS to work:
1. The phone needs to be after a reboot, so it didn't go to deep sleep
2. Data connection (WiFi / 3G) should be enabled before you try to get a lock. Even when you use a satellite-only location! I think it downloads the satellite data from the internet. When you get a lock, the data connection can be disabled.
This is the only way I could get my GPS to work in ICS. Even in ROMs that promise the deep sleep problem was fixed.
Cyanogen never let me down, I was usually using some kernel that a worked with the ffc mod, but I literally never had a problem. Also try any miui with angry GPS

I did the this (kept stock kernel though) and flashed the files from this post...
http://forum.xda-developers.com/showthread.php?t=1550327
The trick that worked for me was to get a GPS lock as soon as the phone boots up but before the screen shuts off (see Post #26 by dark79 in the above link). Usually takes about 30secs to look but works great even after deep sleep.

GPS Problems with CM13

Anyone else having problems with GPS on CM13? Seems like no matter what I do I can't get the GPS to work right with any navigation app I've tried. When using Maps, it finds my location, but when I actually nav to my destination and start moving my location jumps around sporadically and it causes me to go off course and get all screwed up. I've asked about it in the actual ROM thread and have messaged the dev directly and I'm getting nothing. If anyone else has/had the same issue and knows a solution please advise.
I'm currently running [ROM][CM13][6.0.1_r72][VZW][OTA-Updates] Temasek's UNOFFICIAL Build V12.2. I clean flashed the latest update to start fresh. This solved the crazy battery drain problem that dirty flashing the latest update had caused, but the GPS is still whacked.
Thanks.
Did you ever find a fix to this? I just flashed build 12.3 20161220 on my N900V and it's unable to see any GPS satellites.
Won't matter, Cyanogen and CyanogenMod will be shut down as of Sunday.
