I was using my GPS (Navigation) today and I was using GPS Status to get a lock, then open Navigation and for ~5 minutes the app would have a lock and then it would say "Searching for GPS" and would not lock again unless I opened GPS Status. The status bar icon would stick or not show at all, very finicky. Never happened before, but I was lucky I had already downloaded amazinglarry's flashable GPS partition wipe, I flash it, reboot, start GPS Status and then Navigation and a repeat! same crap again.

So, I come in this thread, see yours and others comments, and this is my new process:

uninstall GPS Status

reboot into recovery wipe cache, dalvik, and flash amazinglarry's zip

boot phone and wipe Maps data

Now, on my 15 minute ride home the Navigation app maintained constant accurate GPS.. I will continue to test this week on longer drives, but I'm strongly leaning towards that you are correct, GPS Status isn't playing well with CM7 on DZ
[G2 and Desire Z General] trjcasper:
Thanks for this. Fixed my gps not locking on. :)
[G2 and Desire Z General] xsteven77x:
Well i think we all have learned the lesson. CM7 AND GPS TOOLBOX DO NOT MIX. DO NOT USE. PERIOD. Our phones work well without the need to supplement all the "xtra" data and such. I as many other have had other phones were using these types of apps were a necessity, but that is just not the case with our phones :)
[G2 and Desire Z General] FiveInline:
After this operation, it took ALONG time to get a fix the first time, but now it seems pretty fast.

So, hope that this fixed my slow gps lock i have sometimes!
[G2 and Desire Z General] crachel:
subsequent testing on longer car rides, and I'm still getting the waiting for GPS/dropped GPS connection/stuck status bar icon even with GPS Status & Toolbox long gone.. back to the drawing board.

On next stable CM7 release, I will full wipe/and test and see if I can narrow any other apps down
[G2 and Desire Z General] killswitch11:
OK so I've been having GPS issues for a long long time now. I flashed CM7 when it came out and it pretty much disabled GPS completely. I flashed a new radio and it seemed to improve things a lot. I did install and use GPS Status and noticed that I'd have to reset the AGPS data and download again pretty regularly to get things to work. For a while. I flashed the newest radio and things went to crap. So I went back to the previous one.

I am now at CM 7.0.3 and have gotten rid of GPS Status. What I have noticed is it takes a long time to lock but usually does... eventually. If I pull up Maps, I'm fine. If I try and use Navigation, it will work for a few minutes, then freeze and state "GPS signal lost". Very unstable. I also have the GPS icon getting stuck on the notification bar even when off. I've tried uninstalling/reinstalling Google maps and done all of the above, plus the wipe_efs data many times. Anything I'm missing? Is it down to a full wipe and reinstall?
[G2 and Desire Z General] crachel:
There is a very general GPS bug fix in 2.3.4 that was listed as a Nexus One problem. The reported problem reads like what we are experiencing, so hopefully it helps us out here. I'm mobile right now so i dont have the link
[G2 and Desire Z General] killswitch11:
Hopefully! What is weird is pretty much everyone else's GPS issues seem to have gone away by now. So I'm thinking GPS Status might really be toxic in a CM build, period. I also wonder why Maps seems to work OK, but Navigation freezes and loses signal. Frustrating. I'm about to go out and check it again now that I reflashed the previous radio and installed 7.0.3. In no joy there, I guess I'll be looking at a wipe and maybe even a new ROM. (Looking at Xboarder56's stock Gingerbread build)
[G2 and Desire Z General] nordvik:
I didnt manage to get contact or something whwn trying to do the fix via pc.

So i tried the 2. way.

Downloaded an emulator, and started typing. After writing the first line i got this message:

/dev/block/mmcblk0p13: write error: No space left on device

6145+0 records in

6144+0 records out

after the second line i got this message:

/dev/block/mmcblk0p14: write error: No space left on device

637097+0 records in

637096+0 records out

after typing reboot i got the message: not permitted!

What to to then?

That is for Vision aka tmobile G2 and HTC Desire Z, not Inspire! Consider youself lucky if your phone still works as you are messing with commands that could brick your phone with a single typo. Don't install/flash roms and files or enter commands not meant for your phone.
[G2 and Desire Z General] meepmopmop:
So what do we do? The steps on the first page are confusing!!!
[G2 and Desire Z General] EdKeys:
IF you have a G2 or a Desire Z, download the vision efs wipe tool from this thread and flash it through recovery:

[G2 and Desire Z General] Mr21er:
I was having the same issue and I used amazinglarrys g2supper wipe and then reinstalled rom and it fixed my problem ..... I did not have to flash radios
[G2 and Desire Z General] Malobestino:
I would like to thanks because i've managed to get the GPS working on my DHD even if I'm so noob.
[G2 and Desire Z General] xsteven77x:
It has been proven beyond a shadow of a doubt its toxic!

For all still having issues, did you do the efs wipe? That seems to fix everyone...
[G2 and Desire Z General] killswitch11:
I did the efs_wipe several times. Both manually through emulator and flashing the ZIP via recovery. No dice. I took the plunge, did a superwipe, and flashed the leaked Gingerbread build from Xboarder56. Very stock compared to CM but nice and fast. Will post tonight after I test GPS navigation. (No more GPS Status!!!!)
[G2 and Desire Z General] killswitch11:
GPS working great...! Fast lock, stable for the whole car trip. (All whopping 15 miles of it...) But that's a definite improvement over CM7. This stock 2.3.3 build is pretty impressive so far.
[G2 and Desire Z General] dunes20:
Had a similair issue use g2 superwipe and reload pc10 img if you are messing with that. If your not sure what radio go to settings-about phone-software and than look for your radio in one of the radio threads. I personally use .17 which is a newer one and it is great for gps and data.
[G2 and Desire Z General] EdKeys:
I put a copy of the flashable version in my dropbox. This is for a Tmo G2 or a Desire Z (Vision) only so all other lurkers beware.

I have the 26.04.02.17 radio, with CM build #65. This fix did not work for me. Interestingly this radio worked just fine with the CM 40 builds, gps worked great then all of the sudden it stopped working altogether. I'm not certain at which build it happened.
[G2 and Desire Z General] odin13:
So this works for Desire HD??

I just flash the zip from the first post??

Thnx in advance!
[G2 and Desire Z General] Simer03:
so did anyone else notice that when flashing this thru recovery, it puts these two files in your sd card, something with 13 and 14 in it!?!? what is that??

Worked on my HTC Desire Z with CM7 7.0.3 radio 26.03.02.26M, GPS now works!
[G2 and Desire Z General] xsteven77x:
Not having any problems, but just curious. What would we actually do with the part 13/14 backups? Are we ever gonna really need them? Have yet to read of an instance where the backups are necessary.

THANK YOU!!!!
[G2 and Desire Z General] SNadler:
Will this tool work on all android phones?

I have an Inspire also, Is GPS set up the same way?
[G2 and Desire Z General] MidaZtheBeast:
HELLP!! lol

ahh!!! this is my EXACT problem right now. except im using a nexus one. Just says searching for gps forever. im currently running cm 2.3.4 nightly#70 but the problem started when i first flashed cm 7.0.2. I get a grey navigation icon while its searching but it never finds. funny thing is, its finds my location fine, but navigation never works. just searching for gps forever. any hope for a nexus one user over here?? Ive tried the few suggestions in here i deemed safe to try.
[G2 and Desire Z General] xsteven77x:
You need to find out what partition on your phone the radio/gps cache is stored. Wipe it. That is the same type of idea of what we are doing here. Hopefully that helps get ya going in the right direction.:o I would also recommend trying to back it up first if you can. I'm also sure some dev with the know how could write a very easy script for you so that you can't mess it up. But it would obviously have to be someone familiar with the nexus setup. Good luck!
[G2 and Desire Z General] erouz:
guys i try this metod to fix my DHD but after write all this command in terminal.

i get information "successfully wiped partition 13 and 14."

but then when i want reboot i get information "not promitet"

what to do now??
[G2 and Desire Z General] petarpLab:
ctrl+d to exit the adb shell, then 'adb reboot'
[G2 and Desire Z General] erouz:
but that what U write is from adb shell on PC not from DHD terminal application.

or is no difference??

sorry for noob questions.
[G2 and Desire Z General] petarpLab:
ah, ok

then simply exit the terminal and reboot the phone by hand lol

i also have few minor weirdnesses in terminal, one of which is exactly "not permitted" reboot
[G2 and Desire Z General] erouz:
i was do that.

but worse is that my gps still not working.

i try one more time.

tks any way.
[G2 and Desire Z General] petarpLab:
did you change radios?

if you did and you didn't replace certain libs in /system/lib, gps will mos likely not work, even if you efs wipe.
[G2 and Desire Z General] petarpLab:
or the opposite - if you flashed a new rom (its libs are comming with it) and remained with the old radio.
[G2 and Desire Z General] erouz:
yes i was but i flash RIL whit machet to my ROM as well no help.

GPS can find the satellite but losing it and than find again.

it another evening i waste for try fix that.
[G2 and Desire Z General] petarpLab:
from what i can see from comment 241 here: http://code.google.com/p/cyanogenmod/issues/detail?id=2090

there's another lib that should be replaced - gps.vision.so
[G2 and Desire Z General] erouz:
it is interesting ideal but not for DHD and it for CM7 so still i need to looking for some thing else.

but tks for searching if i find some thing I will post too.
[G2 and Desire Z General] petarpLab:
what is called gps.vision.so should be similar, but with the bolded part replaced by your phone's generic name.
[G2 and Desire Z General] erouz:
i thing is sort it.

is not as fast as was originally but works.

i will check that on the rout in tomorrow

i was install radio than new rom for that radio and look like is fine now.

tks for U help.
[G2 and Desire Z General] SNadler:
Does anyone know if this will work on an inspire 4G?
[G2 and Desire Z General] dyndragon:
I'm on CM7.0.3, 12.52. 60.25_26.08.04.30 Radio, tried the EFS wipe, froze GPS status app (does it really need to be uninstalled? Or just not running it is good enough?) and I still get intermittent GPS signal loss, even though the GPS icon is solid. The only way to get it back is to restart the nav/map app, or disable and then reenable GPS in android settings.

Really bothersome...it seems to happen most frequently when i switch apps away from the nav app while navigating, and then switch back.

any more ideas?
[G2 and Desire Z General] erouz:
what navigation U use??

i was struggle for a 3days whit GPS. and problem was whit AURA 2.X.X

app was working but lost signal all time.

i was install one from android market and then i discover that problem was navigation soft not my GPS.
[G2 and Desire Z General] dyndragon:
I'm just using google maps and google navigation.
[G2 and Desire Z General] crachel:
I have same issues, so I just fully wiped with SuperWipeG2 + efs wipe and I am not installing any apps other than Maps and am going to test on the way home today. Will report back this evening.
[G2 and Desire Z General] dyndragon:
Ok, so I think I fixed my issues.

I am on the latest gb leak radio .30

I took the RIL and gps.vision.so from the leaked gb rom and pushed them to my phone

Then I ran the gps efs wipe zip and formatted cache.

The first gps lock took a loooong time, but after that very fast and stable. In fact, I travelled for more than an hour actively switching apps and tasks, sleeping the display, etc and it was fine and never lost gps lock. By the first 20 min I usually would have needed to reset gps, but not now!

Looks like the RIL and gps libraries have something to do with this for sure.
[G2 and Desire Z General] Thasgolas:
gps question

How reliable should I expect the gps to be - in other words, if it seems to sometimes have problems locking in on a signal, am I having a general problem or is it just not the best gps-capable device in general?

sorry if I sound stupid - haven't had much luck with phone-based gps in general so far.
[G2 and Desire Z General] dyndragon:
You should expect phone GPSes these days to be reliable. If it can't lock in a signal on a modern phone, you should expect it to be a software problem. Most phones these days use the same chips, so it tends to be the software implementation that is problematic--and even then, not common (unless you own a samsung...). That's my opinion anyway.
[G2 and Desire Z General] dyndragon:
By the way, even the GPS icon weirdness (staying on when GPS is not on, blinking when it is locked, etc) is even gone with the pushing of the two .so files from the leaked GB rom.
[G2 and Desire Z General] crachel:
SuperWipe + wipe efs + install nothing but Maps and still get 3 or 4 minutes of Navigation working and then failing. GPS icon sticks in status bar too. going to try new radio and perhaps dyndragon's .so file suggestion
[G2 and Desire Z General] killswitch11:
I think the problem may be CM7. I could be wrong... all I know is I had the same issues. GPS icon staying stuck on notification bar, Google Maps able to locate me but Navigation crashing constantly after a minute or two of use, taking forever to lock, etc. I did same steps as you... Superwipe, EFS wipe, flashed a few radios, re-flashed CM 7.0.3.... all that.

Then I tried a different ROM (which you can see in my sig) and GPS problems are gone. Works like a champ now. It's a shame since I really like CM builds but there is ALWAYS at least one major function not working well that keeps me away. I have high hopes for the next major CM stable release but not holding my breath.
[G2 and Desire Z General] dyndragon:
as i said--specifically, the pushing of the radio ril.so and gps .so files were the things that fixed the problem that I was having. Merely flashing the radio or wiping EFS or superwiping G2 did not fix my problem. only when i pushed the matching .so's to /system did my GPS issues go away.
[G2 and Desire Z General] crachel:
Thanks, I hadn't considered to even check CM's Issue Tracker.. I did find the issue though here http://code.google.com/p/cyanogenmod/issues/detail?id=2090

and see dyndragons comments.. I will be downloading this leaked ROM, yanking those libs and pushing.
[G2 and Desire Z General] killswitch11:
Is this the same a RIL-matching? I saw this suggested for matching a new radio to RILS but OP also suggested not trying this for CM and other custom ROMS. Is adb required? I don't know much about this stuff so just curious.....
[G2 and Desire Z General] dyndragon:
Yes, same as RIL matching with the addition of also matching the gps.vision.so binary in /system/lib/hw
[G2 and Desire Z General] crachel:
Ok, I did the process you outlined (I posted what I did here) and 3 attempts at using Navigation were successful. So, I'm about 90% sure this is fixed. I will keep testing on longer trips.

Just to recap.. for me a SuperWipe + efs wipe + install no apps other than Maps upon a fresh install and my Navigation was still failing. Only after SuperWipe + efs + fresh install + matching RIL and lib file from leaked Gingerbread coupled with Radio 26.08.04.30 has my Navigation app worked correctly.
[G2 and Desire Z General] dyndragon:
Excellent. What im going to do now is install the GPS status app that everyone seems to think corrupts the GPS data somehow. I do find that the GPS does take a bit more time to lock if it hasn't been started up in a while, which I did not have issues with when I had GPS status installed.
[G2 and Desire Z General] crachel:
well... crap. on the way home for lunch I used Navigation and about half way here, the GPS signal dropped.

so, unless someone can tell me why I shouldn't, I'm going to flash that stock TMOUS gingberbread ROM that RMK cooked and convince myself that CM7 is the problem
[G2 and Desire Z General] TobiS87:
Ok... I am in the same situation as most people here.

I am currently running MIUI Ganii's Mod v5.8 and surprise, surprise: GPS does not work. I downloaded GPS Essentials. GPS finds like 5-8 satellites and sometimes I even get a lock after like 4 minutes when I lay the phone on a straight surface but when I move the phone it loses the lock.

Also, when I get the lock the accuracy is pretty poor... it's alsways about 40-50 meters.

So here is what I tried: Wiping EFS, pushing gps.vision.so, matching RILs. The matching RILs thing was not the best idea because then I wasnt able to call anyone - so i restored my backup.

I dont want to flash a radio, because it's too risky in my eyes. So... anybody got any further ideas in bettering the GPS locking and accuracy?
[G2 and Desire Z General] killswitch11:
Well you could try another ROM! Seems to be the consistent fix here. CM7 GPS did not work. Running a rooted stock build and now GPS works great. Flashing a new radio can improve things too and it's not really risky if you do it right. I could link you to a page with all the radios and very simple instructions. All the radios have been tested and verified, and you simply flash them from the bootloader. Takes seconds and safe.....
[G2 and Desire Z General] dyndragon:
For the record, I have installed GPS status after fixing my GPS as detailed before, and I have had NO problems. Downloading the AGPS XTRA data did NOT corrupt my EFS and did not cause my GPS issues like I was having before. I don't think the GPS Status app has anything to do with this...
[G2 and Desire Z General] TobiS87:
Ok, after further investigation I discovered that when I hold my phone just with two fingers at the trackpad and not with the whole hand the signal increases and I get a faster lock with an accuracy of like 5-10 meters. So I guess the signal is just weak. Is this a software or hardware issue?

Perhaps the general GPS signal in this region is just pretty weak. I'll be on this.

GPS cant find any satellite

Hi,

I have HTC Desire HD and using ARHD 5.1.7 ROM and 12.54.60.25U_26.09.04.11_M2 Radio.

I tryed everithing. installed FasterFix and set my region, turned off "Fast boot" under "Settings" ---> "Power" and rebooted the phone, wiped the EFS data and nothing. When I did all above at first time my GPS started to work for 1 day and then stoped, so i did full wipe and reinstalled ROM and Radio and backed on all mentioned but didnt help.

Could someone help/advise how can I back GPS working?

Hello, is it safe to run these commands again? Here is my situation, I was running cm7 nightly 28(I think) and I used these commands, that got my GPS working perfectly(lock on in a few seconds and great accuracy), last night I restored my original nandroid sense, factory reset, and flashed cm7 nightly 91, and my GPS is slow to lock on and out by kilometers. I want to run these commands again, but need to make sure they are safe first

Which leaked gb rom did you get the files from? I dl'ed the original posted by football and found .img files which I didn't know how to extract. Then, I dl'ed one of the other "GB leak" roms that was supposedly not significantly modified and unzipped the two files from there. This morning, I put the new files in the right directories in my G2, wiped efs data and tried a Runkeeper run. The GPS wouldn't get a fix until I opened google maps. This is the way my GPS behaved prior to today. I'll keep testing, but I wanted to know precisely which leaked GB rom you used. ---thanks

I've tried .16, .17, .30.. all with EFS wipe and fresh CM installs (both 2.3.3 & 2.3.4) each situation slightly different but with the same end result, Navigation app losing GPS connection. I tried matching and not matching RILs on .17 and .30.

Sometimes, the Nav app works 2 or 3 times for 15 minutes and I think its fixed, but the next time after about 3 minutes, stuck GPS icon with "Searching for GPS.."

At this point, I'm just gonna carry my N1 and order a GSII :p

Hi all...

Been having issues even after wiping the efs partitions.

Gps starts but then locks up again.

Have found a temporary solution.. (for me at least) .. if I pull down the notification bar.. and simply toggle gps off and then back on.. it then works for the whole trip!

Problem is.. it needs toggling every time.

Hope this helps someone else!
[G2 and Desire Z General] crachel:
I switched to Virtuous G-Lite v1.0.2 on Thurs and have used the Navigation app extensively without fail (probably half a dozen times, once for over 30 minutes). CM would fail typically after ~ 3 minutes

So, my NAM Desire Z running CM 7.0.3 officially is immune to efs wipe (with SuperWipe + fresh install). I will be keeping my eyes on the CM commits and hopefully something appears to address this, but for now I'm on G-Lite
[G2 and Desire Z General] dyndragon:
I've been using the GPS status app ever since this last post and haven't had any issues. GPS status is not the culprit in my opinion. It's unfortunate that others are still having problems after EFS wiping and matching RILs and gps.so files to their radio...I have no comment on that though. It worked for me.
