GPS Fix and CM7 - EVO 4G Q&A, Help & Troubleshooting

I've tried CM7 and gingerbread-deck 1.2s on my EVO but the GPS will not maintain a fix. If I use a sense rom it works fine. I've read that this is a hardware related issue for some folks and is caused by kernel issues. Anyone know if applying a different kernal - I'm considering Savagegen 2.2. would resolve the issue?

There a million and one ways to fix GPS issues on a AOSP ROM. A little reading in the related threads and you should find them. You just gotta find the one that works for your phone.

I've heard flashing over to a Sense ROM and doing ##GPSCLRX# will fix it.

I tried all of the fixes for Cyanogen and Decks and some would seem to work with various apps but then fail as soon as I used Google Navigation.
I would even have a GPS lock on Google Maps and then as soon as I switched to Nav it would get lost.
Back to a Sense ROM and it works fine, but I think it is something with the App.
Does your GPS issue happen across all apps?

I've tried flashing over to a Sense ROM and doing ##GPSCLRX# but when I dial the ##GPSCLRX# I get a recorded message that the number I've dialed is not a working number. I've read many posts that suggest this solution and advise it works. Not sure why it won't work for me. But I'd much rather be on an AOSP vice sense rom and will continue to search for a fix.
Thanks

I say go with the Nexus S 4g. Gps works perfect
Pure 100% working aosp

You have to get the MSL reader app to dial your MSL number and make sure the GPS is on when you do this. It worked perfect for me the first time I did it and m GPS has been flawless ever since.

[GUIDE/FIX] Potential fix for GPS issues with some ROMs

If your GPS isn't working with your new ROM, then try this method. It has worked for me for every ROM I've used with a problem connecting to GPS. I've seen the problem posted in several ROM threads, and instead of posting it in each one and having it get lost in the hundreds of pages of posts, I figured I'd start a new one which might be searched for a little more easily.
- Open 'Settings' and go to 'Applications'. Choose 'Manage Applications'.
- Choose 'Running Apps'
- Find the 'Maps' app and open it. Click 'Force Stop' and choose 'Clear Data'.
- Go back to your app drawer and open 'Maps'. It will have you check off the disclaimers. Close it after you have done this.
- Open your 'Navigation' app and check off the disclaimers there. It should connect after that.​
Like I said, this has worked for every ROM I've tried with a problem connecting to GPS. I don't know why it works, but it does.

Didn't solve my GPS issue...which is that it doesn't toggle on what so ever.
Each new nightly I flash, I have to push an old gps.vision.so in order to get my gps to toggle on and off again.
Thanks anyway.
edit: No app on the market will make my GPS work...That is the type of GPS problem that I and some others are having.
try install the gpxfix or gps status from the market.. work well for me..
Same here...this didnt help.
Also installing GPS status did not help either.
As discussed in the nightlies thread, Cyanogen presumeably updated a crucial library responsible, among other, for GPS functionality which requires the/a new radio.
This also could explain why some users while having identical devices to other users do have GPS while others dont. They simply did upgrade the radio already earlier while the ones which are stuck with a bon-working GPS didnt and are still on the original radio, an "old" one in regards to the prerequisites of the "new" library added to the build.
Makes sense?

Yep...this is 100% correct.
And for what its worth, I went a head and flashed the new radio again just too see if in fact it does fix the GPS and yes it does.
Back to the T-Mobile US OTA radio and the gps.vision.so from Nightly #4 or earlier.
not 100% correct, i have the new radio and still have the gps problem... i've seen at least one other person with the same.
But i'm using a Bell Desire Z, maybe thats why

Did you happen to use the app 'GPS Status' to check your gps after you upgraded? If not, what was the first gps application that you opened after you upgraded to CM7, if you can remember?
Scratch that....just reflashed the radio and nightly 13. Gps works a charm now! Thanks

Im on the stock ROM and have a problem. I think the GPS on these phones are messed up big time. Here is my problem.
stock rom with ota update and ota update radio= no GPS AT ALL it will just stick there blinking tryin to get a fixed signal but it wont! Happens in alll my GPS app not just maps.
So I downgraded my radio to the pre-ota one and GPS gets a fix but takes a minute or so.. after that I can leave the app and come back and itll refix itself within 5 seconds (what it should be normally).. So even downgraded I still have slight issues with gps.. plus for some reason if I loose signal for more than 5 mins on this radio it wont ever get a signal unless I reboot.
Im going to try your method but dont think itll work since my problem is not Maps specific.
EDIT: this seems to have worked, even on my the ota radio. I just dont understand why Maps would break GPS for all apps. Funny things is when something like this usually happens I clear app data but didnt do it here because it was all my GPS apps.
I'm glad it has worked for a couple people anyway. I don't know what the problem is that causes this, but it has worked on the ROMs I've flashed, so I figured it might be a good step to take before updating radios and things like that. Just in case the solution is as simple as just stopping Maps and clearing the data... If you have done more modification to your phone beyond just flashing ROMs, then this may not work for you since the problem may be bad radios or other issues. If you are just a ROM flasher without tweaking too much else, then this may solve your problemo.

I used to not have GPS issues either - european Desire Z btw - having said that, CM7 #14 breaks with that uuhm... tradtion. It's the first build giving me no GPS unless a new-ish (the 26.04 and 26.06 works) radio is flashed.
So wat is the new radio, I recently flashed a different radio but I'm not sure if its the latest radio out. Thx

[Q] Any ROM recommendations with WORKING GPS?

I'm kinda at the end of my rope trying to find a non-stock ROM that doesn't break GPS. I've tried several so far. I can't use any CM7 ROM or anything based off CM7, as GPS is useless. Recently I tried MIUI Bulletproof and loved it, but sure enough, GPS would lose signal during GPS Navigation. The only ROMs that consistently have fully functional GPS for me are the rooted Gingerbread official release and some variations like G-Lite.
There's nothing wrong with these ROMs, but I'd like to run something that has the insane speed and increased functionality that the awesome devs here and elsewhere create. It just get frustrating finding a cool new ROM, loving all the features, then finding that, as always, GPS constantly drops connection or fails to lock at all. I've done all the tricks like efs_wipe and even a proposed workaround bug fix in the General section, but no joy as of yet. So I'm back to vanilla 2.3.4. Nothing exciting, but GPS is flawless. Anyone have any tips of ROMs I may have not tried where I can get best of both worlds? Figured it won't hurt to ask.
Interesting. I'm running CM 7 and my GPS has been working fine. Assuming you did a full wipe between installs and all that recommended stuff?
Yup, I always do a Superwipe+ that does a good scrub as well as wipes the efs partitions. Plus I manually wipe the Dalvic cache. From what I've gathered, random G2 users just cannot avoid GPS problems running anything that isn't stock. CM7 and MIUI give me major GPS woes, whereas stock ROMs give me no issues whatsoever. I've been trying to get to the bottom of this since January and not much luck.
Are you sure u got no hardware problems with ur phone/gps?
My gps is working very good @cm7!
I got the same issue you said with me hd2... gps got lost, never found gps, phone freezes @navigation...
The end of the story was that my hd2 has to be repaired by HTC.

I feel like you're not going to get anywhere with this, since you've obviously tried ROMs that work fine for others. I had problems with GPS on CM7 before, but a efs wipe (and performing Superwipe+ thereafter) fixed any and all issues. The only thing I can think of is to try CM7 nightlies off of CWM (a few user reviews under each) instead of the release. I'm on nightly 204, and everything from GPS, to performance, to battery life is flawless. There's always the option of getting the G2 replaced and trying again.
Good luck!

Well, he did say he has flawless GPS on stock 2.3.4, so we can safely rule out actual issues with hardware.

Exactly. Since GPS works perfectly with stock ROMs, I have to rule out hardware problems. If it was a problem across the board, I'd already have a replacement in hand. The only thing I have not tried yet is RIL matching. Can anyone link me to it? I know the dev who had it up on these boards left XDA and took all his stuff with him. Not sure what it involves or if it may potentially help, but maybe worth a shot. I've tried flashing a few different radios and am now on the "official" radio that came with latest OTA update.

Doing the efs wipe should fix gps problems
Post on ril matching http://forum.xda-developers.com/showthread.php?t=902752 another idea is the change the gps.config file to the US server

Also if using superwipe+ there is a new version with support for 4ext partitions

Thanks for the links. I've tried efs wipe several times. Done it manually via terminal emulator and flashed the zip/superwipe+. I'll look into the RIL matching. The GPS config options appear to be specific to Verizon and the Samsung Captivate, so not sure if that one is an option for me. Thanks again for linking me to all this.

Changing the GPS server should work for any ROM,Im using unity and in the uk so not carrier specific just a matter of opening a file and changing the server values,
Luckily I've never had any serious problems with my GPS so I'm running out of ideas,there is also an app called GPS status is useful but if wiping the efs data is not helping then not sure if the app will help,best of luck finding a solution
You should check out the latest "unofficial" ILWT CM7 212b by tsubus. He includes an option to use stock HTC GPS drivers. I updated my radio to. 30, and flashed 212b (which includes the efs data wipe) and my GPS works flawlessly now. Highly recommend it. Link is in my signature.
All features are now part of/options in version 213, and all subsequent releases. Seriously, it's worth a shot...

[Q]GPS Not Working

Hi,
My GPS stopped working.
After much research and several tests, changing radio\RIL, stock rom.... could not get the GPS working.
Some time ago, after a long time just picking up one satellite, now does not get any.
Is there any tool or application to test the hardware?
Thanks.
rom do you use?
I noticed this with CM7.1.
The stock rom I tested was the latest 2.3.5 OTA.
Try this: http://forum.xda-developers.com/showthread.php?p=17081413
Hi,
I tried this with the stock rom and did not work.
I tried with CM7.1 and still not show any satellite.
Sugestions?
Just for the record:
Radio - 27.14.04.28_M
Have the same issue
I like Cyanogen 7.1, but it seems that the gps doesn't work on DHD. Too bad, because it is a really good rom. I have radio 26.10.04.03_M. The same thing as described by others happen:
I turn on the gps, it start searching, and then it stops and the icon disappears even that the gps is still showed as being turned on
My case is different.
Worked for me several months without problems, and fast.
But stop working.
Someone?
I've tried modifying hardware (antenna), changing to stock rom, tried some different radios, editing gps.conf....
I do not know what else to do.
Anyone know some software to test the GPS hardware?
Have you tried changing the NTP servers?
Changing the NTP servers is part of the link spikey001 posted.
Have you tried flashing agps? I haven't got a thread to point you too but there is one in the DHD ROM section. There are about 6 different gps things you can flash, hopefully one of them will work.

You mention that your GPS used to work. Have you recently dropped your phone? It's possible that the GPS antenna contacts might not actually be making contact anymore (either through trauma or just plain old age)? If none of the SW fixes get your GPS working then perhaps you might actually have to do a HW mod?
See this thread for a HW fix: http://forum.xda-developers.com/showthread.php?t=1318892
Don't worry, it's not as scary as it looks!
Hi,
sounds like what mine did.
Tried software and even made the fysical contact better for the gps-module itself.
No luck.
The solution for me was to buy a new gps-module on ebay for 5-10 us$.
Worked like a charm.
Good luck!!
Thanks for all the help.

I've tried the agps reset/download and no luck.

The phone did not fall, just stopped working.
I've tried the HW fix but did not work, still no satellites.

[Q] GPS problem in ILWT CM roms

I really like ILWT cm7 rom, but the thing is I can't get gps to work in it. In all other roms gps works but not it this one. Before flashing rom I have used supervipeG2+4ext, and I have tried several radios with no luck... And I have also tried different settings in ILWT.txt file. + I have flashed and downloaded rom several times so I don't think that it is a bad file/flash. Any ideas how to get gps working?
The following AGPS patch gave me much faster GPS lock on ILWT. But I've never experienced no lock. It went from taking a minute or 2 to lock, to now getting GPS lock within seconds (sometimes less than 5 seconds). I flashed the "Google Specific" build.
forum.xda-developers.com/showthread.php?t=1472870
If you haven't seen the following thread, it may also be helpful. I can't vouch for it at all, as I haven't tried it. I know its been a known problem on CM7 build for some people, for as long as I can recall. But I've personally never had an issue on various CM7 and ILWT builds getting no GPS lock whatsoever.
http://forum.xda-developers.com/showthread.php?t=1028405
The issue has been discussed in various other threads, too. So just do a search. Have you searched the ILWT thread in particular?
Ok I am going to try those later today or tomorrow... And yes I have tried to search, and found few posts with same issues, but didn't find solutions for the problem.

[Q] SlimKat GPS bug

Hi,
I`m not allowed to comment on the dev thread so I`m doing it here...
I love slimroms and I`ve been using it since SlimBean is out there, thanks for everyone doing the hard work!
Since I updated to SlimKat, my GPS doesn`t work, no satellites reception at all. I tried to look for errors over adb and saw that the error is No XTRA servers available...
Just to confirm, I flushed few other CM roms and GPS is working perfectly in these, so the problem is in SlimKat only.
I saw few references in the dev thread but nobody said anything about possible solution.
Would be happy to go back to SlimKat once this problem solved.
Does anybody else have this problem? Any solution?
Thanks.
Any answers? Solution? Anyone?
Can anyone take a working GPS code from any of the other CM roms?
Still doesn't work on new build 2.4
see attached logs.
yeah, this is broken for me too. if i have data and wifi on i can still get a location fix though in the city, but not outside of the city.
GPS Location not working SGH T989 Slimkat
I am having the same issue on my T989, and am looking for a possible solution. I've enabled high accuracy and even enabled the wifi and what not. However, I still cannot get a location. I'm gonna have to switch to another ROM until the issue is resolved, but I don't really want to So if anyone from anywhere can help me fix this issue, It'd help out a lot...
i am having the same issue, can't patch agps too having status 0. it doesn't work when i try copying that files in /etc myself
GPS + Camera issue
Other than the GPS issue, what about camera? The camera does not work for me in Hangouts or Skype (SlimKat).
No camera and no GPS. Try carbon Rom 4.4.2 if you want those to work. Just as smooth.
Sent from my SAMSUNG-SGH-T989 using xda app-developers app
Yeah there really is no point in these posts because even the developer has established that SlimKat has issues with T989 thus the reason there have been no further builds since 2/3. If people are still going to use it anyway then they accept the consequences of doing so. Not ripping anybody but these questions keep popping up all the time. Use another ROM if you want GPS & camera, there are no ifs, ands or buts about that.
