[Q] CM7 Evo GPS Fix - EVO 4G Q&A, Help & Troubleshooting

So i was looking for way to fix the gps on my Evo 4g running CM7 RC4 and i came across this fix:http://www.reddit.com/r/Android/comments/fzqnc/evo_cyanogenmod_7_gps_fixprls_and_htc_sense/
If i back up my rom and then flash the Fresh Rom fix the gps and then flash back to my back up, will i lose my apps? More importantly i do not want to lose my progress in Angry Birds. Thanks

yeah you can use nandroid for this fix. Just warnen ya though, that's what I did initially and I've been having trouble recently. I just fresh formatted everything today.

Nandroid backup your current setup, flash the Sense Rom, do the fix, then nandroid restore. You can always use Titanium Backup to backup your apps + data in any situation. As long as you backup Angry Birds with TB, you can restore your progress.

Also, try GPS status in market. I'm running cm7 rc4 and get perfect lock after doing this.

What's strange is that GPS Status has worked for me so far, but it doesn't work at all for my brother running an Evo, exact same parameters.

I can confirm that GPS Status did not work for me. I'm running CM7 final and I'm still getting flaky GPS. It locks for a second, then turns off. It will turn back on after a few minutes, lock, and turn back off.
So I tried GPS Status and cleared the GPS cache and downloaded the A-GPS data, etc. Same thing. Even in the GPS Status app, the GPS turns on, find a lock, then turns back off.
Therefore, I grabbed MSL Reader, wrote down my MSL code, flashed Sprint Lover, and while in Sprint Lover, turned on GPS, got a lock, performed ##GPS fix and entered MSL code, rebooted, tried GPS again and it worked, updated PRL while I was in Sprint Lover, and everything worked. Then wiped everything, flashed the new CM7 final and can confirm (though limited testing) that GPS is working now as it should. It doesn't flake out on me anymore. I'll test it on my way home tonight.
Hope this helps...

Yep, this works. The GPS Status app never worked for me, but flashing back to SL, performing the GPS fix, and back to RC4 worked. Now on CM7 Final, GPS is working OK.

When you restore your nandroid backup, everything will be exactly like it was, but you can backup your apps with titanium to be sure.

worked 4 me mahalo

Running decks 1.1 and tiamat 4.0.1. GPS status fixed all my problems.

Excuse me im sorry if im ignorant, but what is Sprint Lover?
Thank You!

It is a Rom that looks just like the factory Sprint rom with some tweaks. Here is a link.

Hi folks,
I am running CM7 stable and I had the GPS problem big time. It wouldn't work at all.
I read this post and tried out the fix.
I flashed Koni Elite III ROM, booted it using amon ra, updated prl, then profile, did the ## Gps fix as linked above, checked GPS on the sense rom and it was working, went back into recovery and reflashed CM 7 from nandroid backup, didnt wipe anything, and all is absolutely great again, the GPS locks instantly and Google maps and navigation works fine and dandy....... easy 10 minute fix.

+1 yup, this works all the time.

All I did was turn off "allow mock locations" and rebooted the phone. GPS Status now gets a near instant fix and Google Maps works again. Not sure if it will work for everyone but it sure is easier than having to fiddle with the software.

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

Whats your GPS status?

there have been pletny of GPS threads, obviously. but im wondering what you guys did to fix yout GPS on cm7? my gps worked in the past, but recently when i flashed RC4, the GPS stopped working. and i flashed the latest nightly and it is not working as well. i just baffles me because it worked in earlier builds, and you would figure it would work in more stable builds.
so.
what have you guys done to fix your GPS/what nightly are you on?
As an avid Foursquare user I use GPS every day, several times a day, these GPS issues are the main reason I'm still on the stock ROM.
i know what you mean. my GPS works on sense based roms, which is great. im not sure whyyyy its not working on CM7.

First things first: No indicator on notification bar when starting GPS traffic assist application?
Then you are living under a rock or having bad reception. Go outside. Using some kind of widget which uses GPS also and has a on/off switch in it? Try switching off and reboot. It simply should work with the latest nightlies. Try reflashing and fix permissions. Do not wipe your entire phone before flashing.
Doesn't work for me either with RC 2 or RC 4. I've tried some of the fixes out but no joy. I know how to use it and it works fine when I go back to stock. Issue is definitely with my CM 7 install. I'm hoping for a solution soon as this my only issue, but it's a big one for me.

That's right, yours is working fine. If the GPS is "broken", you won't have any activity on GPS Status. No green dots for the satellites on the round display, and no bars on the bar graph below that. Those will be blank, and you never get lat/long coordinates
It's still working for me on RC4, but locking takes about a minute, whereas it was almost instant on stock.
CM7 definitely does something to gps, very weird how everyone is getting different results.

had problems with gps locking on stock radio with cm 6.1.1 after flashing .27 i get almost instant lock in the house, that did not happen with stock rom or radio.
but my wifes with stock radio and rom did that from the box
both g2
GPS doesn't work at all for me in CM7-RC4 (I mean nothing, no signals or indicators or anything). Works fine in CM6.
I believe I'm currently running the "stock" T-mo OTA radio 12.28b.60.140eU_26.03.02.26_M and haven't tried a different one. Think changing that might help? I don't understand why some people have it working with this radio but not others.
Edit:
OK, I got it working. I had first installed CM7-RC4 using clockwork recovery (in the boot menu) after wiping out the stock ROM. GPS didn't work so I installed CM6 using ROM manager. GPS worked. I then installed CM7-RC4 using ROM manager and voilà, GPS works in CM7-RC4 now. I have no idea what the difference is.
Try .27 worked for me on cm 611 , just flashed the new one, works great, satellites get higher value on GPS test

Sorry, didn't see your post after mine. I edited mine to show that I got it working simply by downgrading to CM6 then upgrading to CM7. Could be a ROM Manager thing or maybe something left over from how CM6 configured the hardware, or who knows.
I do wish CM7 was more stable though, seems kind of wonky.
I had the same problem with CM7. Download gps.vision.so from either nightly #4 or nightly #34. Open up adb:
adb remount
adb push gps.vision.so /system/lib/hw
adb reboot
GPS should work after that.
Radio .26, CM7 RC4, flashed also the "auto-patcher" that patches files to your ROM based on what radio you have.

[Q] Gps only works with Wifi On and Netflix says to be deactivated and napster too.

Hello, I have already searched the threads and cyanogenmod website. It seems it must be hardware issue or drivers, from what I can gather. Although my gps used to work perfectly before. I was on cm7.03. gps worked perfectly to 2m. Then flash sprint lovers. Then back to cm7, I had dowbgraded prl in sprint lovers, but updated before going to cm7, as well as sense gps fix, ##clrgpsx# fix. I would get the 1000meters gps reading. Rebooted back to sense and did fix 5 times no change. Even after dalvik and reflash. I then turned on wifi and it reached to 20m and sometime 10m. So I went back to cm hoping it would be better. I did and when on gps only 1000m and with wifi (not connected) 10-15m. I used to get 3m with only gps, not sure what happened. Any ideas? Thanks in advance
Netflix, I had netflix working on my evo with cm7 and sprint lovers, went back to cm7 and now I get device is not activated. I went to netflix and deactivate 3 evos and nook color. But now I still get same error. I cannot activate it because there is no code to enter online and netflix app doesnt provide one. Any ideas?
Napster, I have 2 phone using this account, but Everytime I reflash I am not able to download to phone, after 3. Is there any way to prevent this. Last time I had to call them and they reset it. Its just that I flash alot. I tried restoring with Titanium and keeping data still needed to call.
Thanks again.

[Q] GPS doesn't work after flashing ROM

I finally rooted and flashed Joel's Sense 3.5 ROM. I've flashed it 3 times now, every time doing a full wipe in between, but I can never get the GPS to work. It says it's on, but never gets any signal. I've tried disabling/re-enabling, airplane mode toggle, *288, GPS Status clear/download AGPS data, everything that I could find online. Finally I just restored to stock/pre-flash and GPS is back working.
Any ideas why GPS would stop working? Did I miss something?
Clearly I didn't pay enough attention, because there's a link for NilsP's GPS fix on Joel's site. Flashed that fix and all appears to be well again.
It's been my experience that Dinc 1 doesn't handle 3.5 ROMs well. I tried a ported evo 3D rom, and acted "buggy" for me.

[Q] GPS not working. I tried EVERYTHING!!!

Hello! I know this is a common thread, but i'm desperate!
My GPS is not locking at all, i left the phone for 10 to 20 minutes and i got nothing...
I'm using the CM10.1 MoDaCo ROM, but i tried so many ROMS, fixed configuration files, walkthroughs, etc, but none of them seem to work.
I'll list all the methods that i try so far.
1) Flash a fixed configuration file
2) Change the ROM: i tried with the stock 4.2.2, CM10, CM10.1 Nightlies, CM10.1 Experimental, MoDaCo CM10.1
3) Flash different radios. I live in Chile, so i tried UGLL1 and UGKL1
4) Clear data of Google Services Framework, restart, etc
5) Used FasterGPS to set my location in the right area
6) Used GPS Status to improve AGPS
7) Change the build.prop file
I tried every method and the combination of them, but nothing has worked for me so far....
The GPS is very important for me because i use it to track my rides with Strava, and since the GPS is not working, i cannot start the application...
I really need help...
I use a Galaxy Nexus Maguro without Wallet and live in Chile. I cannot tell exactly when the GPS started to fail, but at least in the stock 4.1.2 it was working perfect, so i guess it started failing when i updated to CM10 and then to CM10.1.....
Ok try this if you haven't.
In settings turn off all location. Reboot
Make sure location reporting is still off.
Clear data on Maps force stop maps
Reboot
Clear data on maps and force stop again
Enable location
Get gps lock with maps or easy gps.
Might not work but I have had your same problem and this fixed it .... good luck

Hi!
Thanks for your answer, but unfortunately i've already tried this method with no succeed. I tried again but it didn't work...
Thanks anyway, i'm going to try to roll back to stock 4.1 (because the GPS was working with that version)
and if it really works i'm going to upgrade to 4.2 to see if i can find the error...
If someone else can give me a solution i'll appreciate it!

I already tried, but with Android 4.2.2 and it didn't work.
Before i flashed the 4.2.2 i was using stock 4.1 without problems, so i believe, and hope, that this is a software issue in the 4.2.2 update...
I'm going to try it now and i let you know.

My GPS got worse after upgrading to 4.2.2. Lock takes much longer and finds less satellites
- wore out your welcome

Well, i returned to Stock Android 4.1.2 using Fastboot, but the GPS didn't work either... So i updated via OTA to 4.2.2 and the GPS didn't worked again...
But i noticed that the Nexus S belonging to my sister, wich uses CyanogenMod 10, is not working either!
So i have a doubt now: Is it possible that CyanogenMod could have ruined our GPSs? If i erased everything via fastboot, is it possible that some remains of CyanogenMod could still be breaking my GPS? Or are our GPSs, strangely, broken at the same time?!
Please Help!!!

Out of my realm of expertise, but I imagine the sirf chipset is not user serviceable. Your best bet would be Samsung factory service. I'm sorry.
Well, after giving up on trying to solve my GPS problem, it fixed itself.... i know that sounds weird, but the only thing that i did was update the CM10.1 to the latest RC2 and the problem was fixed, at least partially. Now it can find some satellites and it takes like 100 seconds.
The Gnex GPS isn't the best one, so it behaves a little weird some times, but at least is fixed now...
I really don't know what could be the problem, because i tried with almost any Rom, officials and no-officials...
Finally, the CM10.1 RC2 fixed my problem, hope this could help someone else.
Enable wifi & mobile network location in settings
Should be some code in 4.2.2 that prevents you from getting AGPS data if you disable the said option.

The problem is fixed now, but i tried everything, from rolling back to 4.1 official to 4.2.2 official, CM9, CM10, CM10.1, AOKP, etc. So i really don't know what could be the problem. I also tried the solution that you told me, but that didn't work either.
Right now, with CM10.1 RC2 my GPS is working great and i'm able to use Strava again.
I've been having the same issue. I'm running a Stock Verizon Galaxy Nexus, on my third one now. I have tried everything from apps, to resets, to disconnecting the gps, and nothing seems to work. It just seems to take forever to get a GPS lock, sometimes I just have to reset it. Not sure the issue, and I can't seem to find anyone with answers either. IDK if anyone found anything??

Cold start gps can take up to 20 minutes outdoors with a clear view of the sky if you don't have current agps data. Thereafter, you should have quick starts for a day or two.
Is your data working properly? Do you have sync settings turned off?

My data is working just fine, I actually have great 4g where I'm at, and all my sync is turned on. I've never had GPS problems with any of my other phones. I had an EVO 3D, and it worked great, cold starts would take seconds to find GPS.

And you have certified that all the gps settings/permissions are turned on? Even in the Google settings app?
Since you are stock, it might be helpful for diagnosis to preform a factory reset.
Edit - I see on another thread that you have already performed a factory reset. Next step would be to flash the factory image and see if that helps.

Thanks, I'll have to look up and see how to do that without root and boot loader unlocked, this is my third Galaxy Nexus from Verizon, they keep replacing it and I keep having the same issue
And yes all setting have been turned on, kind of driving me nuts
I'm sorry for you. it must be very frustrating.
As far as flashing an official factory image, I think you can do it unlocked if you have adb set up. Or use a toolkit, unlock, flash factory, relock (or not, why not keep it unlocked?)
