[Q] GPS repair on CM7 - Any good repair shops? - Desire Q&A, Help & Troubleshooting

Hey you guys
I need some help with my HTC Desire.
A while ago my GPS stopped working. It won't get a fix no matter what I try, in any app (maps, GPS test etc).
I've since rooted it and now using CyanogenMod 7. It's still not working. I assume it's a hardware malfunction. The GPS hasn't worked since my screen was replaced a few months ago by HTC.
My question is:
1. Is there anything left for me to try??
2. Does anyone know any repair places that will
a: fix my rooted phone with my CM7 ROM?
b: do it pretty quickly in a few days tops?
I would love to know if I can fix it. Many thanks to everyone that's read my post.

Send it to HTC to get it repaired. Just remember to use an RUU

Download an app called GPS status and toolbox.
Reset the GPS and download the data (using that app).
I found it helped mine.
I have a slightly different issue.
Helped with the locking though.

Im running cm7 rc1 and Im having problems with GPS not working.

Desire Froyo 2.2 update. GPS fix issues.

Hello All.
I know this has been covered a little before through the search but im still after some advice.
I "upgraded" from my n85 to the HTC desire last week. I imediatly got the 2.2 update on there OTA and all was well and good. However i appear to be having issues with regards to getting a gps fix.
A-GPS apears to work fine and i can get a position on googlemaps within a a min. All well and good if it actually showed my proper location. So im sat there waiting for a gps fix. I.e. last night i was sat there for 10 mins on the moors in the car, frweezing my knackers off, and still nothing!
Sooo
if i reboot the phone i can get a gps fix within a min or so. But i have to do this if i want to use the gps which seems a bit rubbish to be frank and ive got the iphone boys laughing at me because theres fixes straight away.
So what am i doing wrong? how can i get a good fix from the off? Its spoiling anotherwise good phone.
I have this problem in Google Navigation also. As you say, after rebooting the phone it finds a fix pretty much straight away.
This is my biggest annoyance with the phone right now and I hope they fix it soon. Prior to 2.2 I didn't have this problem at all so I am sure it is a software problem.
Hmm i'm afraid there is nothing really to fix. My Desire gets a GPS-Fix out of any situation straight away within 3-5 seconds (outdoors of course)...
Maybe a different radio would sort out this problem? I`ve heard talk of different radios being better for some and not for others, Trial and error I supose.
O and my GPS fix seems rather slow too.
I also have significant delays in getting a GPS fix. I do not recall if it was the same behavior before I did the HTC OTA FroYo update.
I also notice that I never get very good "signal strength" (as measured with the app GPS Test) from any of the satellites, even when I DO have a fix.
Hello.
I recently bought a secondhand HTC Desire and I am having the same issue.
It has stock 2.2 on it and it can not get any GPS fix whatsover.
I have tried rebooting, taking sd card out and back in, taking sim card out and back in, etc. without any luck.
I have tried apps such as GPS Status, GPS essentials and GPS Test and they all either are stuck at searching for ever or show 0 visable and 0 used satellites.
How can I fix this issue? It is rather important. If I install one of the various custom 2.3 ROMs will it fix the issue?
There isn't Desire with vanilla Android. If it has stock FroYo, then it's custom ROM.

Sorry, my mistake.
I meant it has the official 2.2 Froyo with HTC Sense as far I can tell. The previous owner must have upgraded it to that.
Anyway, is there any way to get my GPS working?
Try to root, s-off then update the radio to the latest. Search the forums for info on how to do that. It's rather easy if you're a little versed with computers.

Done. Still doesn't work.
That's weird. It may be a hardware issue, then. Get GPS Status from the Market, install it and see what's going on under the hood. Does the phone "see" the satellites but can't get a fix or does it not "see" any satellites at all?
its not difficult understand if there is an hardware fault or not
run the latest froyo ruu, go out of ur house, enable internet connection, enable gps, open gmaps...after few seconds u should get ur exactly position with a possible error of 1/2 meters
if even after some minutes, and even in different locations/city, it doesn't show ur correct position, call htc and sent it to service with warranty.
solved
0 satellites seen and 0 satellite fixes.
According to the previous owner it didn't have the GPS problem before the 2.2 ota update, which would make me think it is software related.
Never trust the seller. Of course he/she will not admit that the product they've sold you has/has had issues. I would return it, to be honest.

[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.
tags: gps not working, gps won't connect, gps issue, broken GPS
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] Can't use GPS?

Hi everyone, i've been having problems with my GPS on my HTC Desire a8181 here and I just don't dont understand why.
The phone I had before (HTC Touch Diamond 2) had GPS as well and although it wasnt as powerful a phone as this baby, it actually got the job done for me.
My phone is rooted and "S-OFF"ed.
I bought this phone and since the day i got it i couldn't get GPS to work... ever!
I am using the LeeDroid 2.3d rom
I have tried all of the roms and just can't get it to work.
I even changed the gps.conf file to the asia pool as I am located in Bangladesh.
I get 0 views and 0 locks on GPS test
I would really appreciate any type of help as I have done everything i could to get it done, and paid a lot of money to get this phone!
Thanks in advance!
If it never worked it's most likely hardware related. Did it work on stock unrooted rom?
If not, Ruu and send back to hTc.

Yes you can use gps but depend upon the version and screen resolution.
If you download high resolution application it wan't run. and it also depends upon the version.
Well i never really tried it on stock, but im guessing the gps.conf file in the stock is going to be set to the europe pool while im in asia =/ so i don't think its gonna be any better
? I used gps test and gps status... and i don't think it has to do with the resolution??

Problems with google maps, he remains paralyzed searching gps..

like the thread title says i have this problem.. my google maps is always "searching for gps" in the Navigation function
few threads ago i was posted a problem with GPS STATUS or GPS TEST...
They were not finding any satellite...
later with the help of @superstick1 & @blbean i was fixed it... now these apk finds even 7 satellites!!!!(often LOL)
but Navigation continues without work.... some suggestion?
i was tested:
1-reinstall the apk. (not fixed my problem)
2-erase data caché OF THE APP only (not solved my problem)
3-fix gps sat. with gps status(not solved)but 5 satellites found...
4-use FASTERFIX.apk and then restart my machine (not solved)
EDIT: ufff! i´m desperate more tries:
5-flashed another recommened rom from coredroid thread: 12.28g.60.140f_26.05.05.27_M3 (orange uk)but its weird because i´m living in spain (orange es) (NOT SOLVED MY TROUBLE)
6-flashed another kernel: from leedroid 2.2.9 to my current BUZZ 1.3.8.3 1.2 GHZ MAX(NOT SOLVED)
I AM GRATEFUL FOR YOUR HELP BOYS (OR GIRLS )
Have you tried using a different rom and/or kernel?

i tried that @lordvimes was recommended me, change the kernel but the problem persists now i have buzz kernel 1.3.8.3 version
Hi SERGI.3210
We meet again. Lol. I notice from my own experience that if we often reboot our phone, the GPS state will be restarted. And hence it will take some time for the GPS to work again.
For example, I have once flashed LeeDrOid' v2.2.2 in the past few months(first time), and I got a fix very quickly. It will be within 5-15 seconds? At most it will take is 30 seconds. However, after I reboot for whatever reason(I forgot, but I am not flashing anything else), and the GPS takes more time to get a fix again. The situation got worsen when I am in the car to get a fix. Took about 5-10 minutes??
But after some time, tolerating such slow fix(I know, its annoying) it suddenly get back to normal again. Which means I can get a fix very fast again.
Many has recommended the use of GPS Status app to clear A-GPS data and then download them back again. It works for them it seems, but in some to a large extent, it did not really work for me.
Maybe you can try Ulysee Gizmos app from the market? It has the capability to download A-GPS data as well. Recently I try using it and it seems to fix my problem once again. When was it? Last two days ago. Lol. Now it still work fine. Hopefully this continues.
I am still use GPS Status to get A-GPS data. Which means I am using both of them at the same time. Probably both apps does fires out some solutions? Haha. Me not sure but you can try.
Cheers mate. =)

hey buddy!! how are you?!
okay i´m going to test this:
-1-clear A-GPS data of the gps status.apk AGAIN....if not solves:
-2-download Ulyse gizmos.apk and try it...if not solves:
-3-I will go to area discovered to trying... if not solves... maybe i will go to reinstall the all the apk relationed with GPS..and if it not solves that
-4-I believe that I will think of burning my DHD.. lolololololol
thank´s for you usefuls posts man..
see you soon here
EDIT: i tried to install another GPS NAVIGATOR (sygic) BUT THE PROBLEM PERSISTS... i´m really sure that the problem its that my device finds gps when he wants And if it is clouded less still
I am fine here thanks. Getting ready for work now.
In your case, the problem is nothing to do with the navigation software but your GPS cannot get a fix. It may due to hardware failure.
If the situation persist, probably you should consider sending your device to HTC for a check. But make sure you turn back your phone into normal state first. (i.e. unroot your phone)
i pretty much have the same problem ...
5+ mins to lock my position ..
RcMixHD 5.5 and a changed radio... i will just burn it..

edit:i´m going to try CM7.0.2 and test gps again but i´m Considering to take it to the technical service....
So you finally got a fix? Congrats!
Yea, try to send it to HTC for a check. By the way, again, remember to unroot your phone first before sending to them.

good night buddy!!!!
i have soo good noticesx100000000000
THAKE THIS:
gps status:found 8 or 9 sat.
fixed in 62 segs.
google maps:working perfectly!
finding gps at the moment
15 meters position error max. (better than my htc hero)
THE MEDICINE:
1--Though I feel sorry very much I had that flahs another CUSTOM ROM
2--Then I´VE flashed the recommended radio and was foun 3 or 4 sat...
3--and the most important: flash the RIL for this radio in this moment i was found 8 or 9 sat.!!!
the only one thing that i don´t like (nothing nothing) is the custom rom:
RCmix 6.1.0.1 (ported from desire s)
i´m COREDROID LOVER and RCMIX seems too simple but i preffer the good performance before beauty things...
Nevertheless when it does a few kilometres and tested well the GPS I will try with Leedroid (froyo) to see if I obtain the same results
Good for you buddy!
Usually if you got a fix pretty quick, it will have errors ranging to 30-50 meters(that is from what I obverse based on my device that locks within 5-15, max 30 seconds). Then it will adjust overtime. Well, still better than doesn't get a fix at all.
Hmm.. RCMis HD6.1.0.1? The Evolutionary Sense ROM? I have not try that yet.. plan to try after my exam. Currently concentrating on my exam for this month. Also quite satisfied with my current flashed LeeDrOid v2.2.3 ROM now. Lol.
Probably will be trying Miui too. I would prefer staying with Sense ROM as there is unlikely to have Premium Navigation in Non-sense ROM. If I would to try other GPS apps, I will have to pay for it. Premium Navigation is free for life for me in Malaysia + Singapore. Also finding addresses with it is easier, unlike other GPS app.(i.e. cannot search address). Probably due to the names of addresses here. Here uses Malay names and not English.

Evo 4G GPS issue

So about 4-5 months ago, I became frustrated with the GPS woes on my otherwise perfectly operational Evo 4g and went ahead and bought a "refurbished" Epic 4g instead. I miss my Evo 4G like crazy and with work slow for the next couple weeks, I decided to revisit the issue to see if i can maybe fix the problem and re-activate my Evo 4G.
I am a relative n00b but know enough to have exhausted every possible solution I could find using the "search" function. GPS Status AGPS resets, ##GPSCLRX# fixes, as well as pretty much every single driver fix listed here: http://forum.xda-developers.com/showthread.php?t=1132412
thinking back to when the issue began, I think what I did was install a CM7 AOSP ROM over my then stock-rooted ROM, when the GPS didn't work, I kinda freaked out and nandroid flashed back to what i had before but the GPS issues persisted.
I thought about unrooting completely back to stock but if the GPS is the only thing not working, I'm wondering if that would even fix the problem.
It could be a kernel issue perhaps? I'd be more than happy to provide any info/screenshots/logs that might be helpful.
Any thoughts/suggestions would be very very much appreciated
*Edit : in the time since I made the post, I decided to follow this thread and install everything anew, ROM, kernel, GPS drivers/fix (AOSP all the way, CM7 + Savagezen + CM7 N39 Driver ). Still nothing with the GPS, the GPS Status app just will not lock on to a satellite.

that would be very sad indeed. Did you try going back to stock completely (unrooted) to see if that would help? that's the one thing i've not tried and I guess i'm just wondering if anyone thought/knows whether that would make any difference in this case.
(in the meanwhile I flashed miui's ice cream rom on the evo 4g using it mostly as music/media device and it's so freaking gorgeous...looks like i'll have to go get an S3 after all)
