[Q] GPS repair on CM7 - Any good repair shops?

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.

GPS Problem with new S2X

Hi all, exactly 2 weeks and 1 day ago I got a S2X, everything has been running great except it has a problem..
The GPS does not seem to work at all.
I've searched the net for any possible solution and most people have said to download GPS status or other similar app and wait till the phone gets an initial lock with more than 6 satellites. But here's my problem, my phone's GPS does not seem to work at all, whenever I try to locate my location it'd just gets stuck on SEARCHING FOR GPS for a looong time.. I've made sure I tested this on a clear day/sky so it should work..
Although, it seems like the GPS unit is able to get fix/sat but on 1-10 sattelites, it still says it is searching for GPS..
Because I bought this phone out from Koodo without a contract and It has been over 14 days I can no longer go back and exchange it.. Is there anything I can do to help fix the GPS problem?

EDIT:
I've tested this with a Telus SIM and Mobilicity Sim and both seems to work! GPS Status tells me that it is able to get fix/sat however the GPS icon still flashes and Google map still doesn't work..Also, there is no latitude or longitude or last fixed or even altitude as this picture..https://lh5.ggpht.com/JSUWXboRPtXJ_jTkWPx1MFizLa2TXA5U3kUHSunuNYY_CuE6FJpkTu2AFum_jlCcqydw
It only shows fix/sat and direction

No need to test Sims. It should be able to lock on without a Sim. So the problem is that your, phone doesn't lock on even though your apps says it does?
haven't heard of that problem. Have you tried a factory reset? Or a clean wipe if running custom roms?
What fixed it for me is flashing a modded radio.

You can try GPS Test on Play store. Open that app first, and wait until the satellites are locked, then open Google Maps. It will make Google maps locks faster. For me, google map is lazy and refuses to fix most of the time, but other gps-related apps still work great. I think its google map's issue, not your phone.

I also own galaxy s ii x. I have same issue. It has been like that since official ICS came out. No matter which radios or ROMs I use from JBs to ICS, I can never ever get GPS lock on google map period.
I was only able to get gps working again When I had gone back to Telus stock gingerbread.
I am still searching for a fix. It is not that your phone is defective. But I also wanna know how to solve this issue.

t mobile galaxy s ii
To hopefully help, I have a t mobile galaxy s ii. Had the same problem, brand spanking new phone and never really been able to get a GPS lock. I finally called t mobile and described the problem to the tech support people, went through my troubleshooting steps (reset, upgraded, etc, etc...). My new phone arrived yesterday....its a totally different phone. Same phone but it feels different. GPS locks with no issues...
You may have a hardware problem....

I have a s2x from Koodo as well, just ran navigation/google maps and got a gps signal in my basement with no probs. I am using AOKP rom though.

Did ur phone originally come with ICS or did u update via OTA?
Before u ever installed AOKP that is.

After I used odin back to Telus GB stock 2.3.5, I gained gps back.
I just rooted it and then flashed ptmr3's koodoo v3 ROM along with koodoo ics stock radio.
After several tests with gps status app and google maps, I have just confirmed gps locks in and works fine. Though gps does lock in very slow, I am just happy that the gps works now even on ICS

[Q] Problems with Mobile internet

I am facing a very peculiar issue that makes my mobile internet dysfunctional. Whenever I switch from 2G/3G to WiFi and then switch back to 2G/3G from WiFi, the internet refuses to work unless I restart my phone. Once, the phone is restarted, it works like a charm again till the time I switch to WiFi again. Sometimes though, 2G/3G would not work even if I do not switch to WiFi. Also, rarely, it still may work even as I switch back from WiFi to 2G/3G. This issue has plagued me since a long time and is sometimes accompanied by call drops.
I took my phone to a Samsung Service centre but it wasn't of any use. They do nothing except reflashing the stock rom. It did fix the problem for a while but in an hour or in a day(or in some random time duration) the problem resurfaced. I took my phone to the service centre, just to get this problem fixed. I have tried switching between different modes in settings: GSM/WCDMA/auto etc
I also tried contacting my mobile carrier and got my sim card changed. Therefore, the mobile carrier is not at fault (Internet works flawlessly after I restart, remember?). How do I fix this? It is really irritating to restart the phone every time I need to use the internet. Please help! :-/

Maybe try flashing a different modem. I had various data and call issues on my i9300. After flashing 10 or so different modems I found one from aveuropean carrier worked best. Im in the uk btw

Thanks for replying thedadio!
But I've never flashed a modem before and have no clue which one to choose. Is it same as flashing a custom rom? Also, can I brick my device while flashing modems?

Yes its similar to flashing custom ROM. What ROM are you on and what modem are you on?

McLaren__F1, I am on stock 4.1.2. Also, I just tried flashing DDALJ1 modem (As I'm from India) and Perseus kernel. None of these steps helped me in any way. Still the same issues. :-/

Which is your network provider? I had the similar problems when I was on docomo..nw ported to airtel nd problem solved.
Btw did you try some other np's sim?
Sent from my GT-N7100 using xda premium

I am currently using Airtel (Prepaid). I haven't tried using any other np's sim though..

I have the exact same problem. I am with optus Australia. I tried different modems, different ROMs but all have the same problem. I have sent mine away to be replaced and am still waiting for the new one. Very frustrating problem.

I'm not sure if they'll replace mine. It has been almost 6 months since I bought it..
How do I solve this? Any clue anyone? :|

My Note2 does this sometimes & only fix is a restart.

try soft format may its helpful

Not a fix, but toggling airplane mode on and off does the job for me.
Interestingly this happens to me only when leaving one particular WiFi access point.

i got exatly same proplem, 3g not working after leaving wifi of my workplace, but when im home i have no proplems if i decide leave my home network.
could it be related to radio type wifi has?? my workplace still using old hardware with radiotype of .g and leaving that network "kills" mobile network and i need to reboot phone, but my home network is .n and im not having proplems after leaving it. if its related to wifis radiotype it should be easy for someone to write script which reboot mobile network after leaving those wifi networks.

Doesn't work for me. This problem is strange. :-/

No one has a solution for this problem on XDA?

Did you use the NFC to scan anything by any chance? I don't know if it could be related but my phone started to have issues around the same time I bought some NFC tags and started programming and scanning them.
I still haven't got my replacement phone back yet. But I'll let you know if it still has issues in my problem spots. Than we'll know if the problem was with the phone or just this model.

Nope! I haven't used NFC at all.
Ohh, okay..Eagerly waiting for your response! *Fingers crossed*

Tested replacement phone today and the problem seems to be gone. The signal was actually stronger than all my previous phones.
This issue could be a hardware problem as from what I have searched on the net it seams to affect only a few people. I just hope if I root the phone the problems don't come back.
Maybe you could try send it away for repair if they won't replace it.

Looks like I spoke too soon. The issues are still there. While waiting for my replacement phone I was using an old HTC wildfire and had no issues with the data connection so it must be an issue with this model.

[Q] GPS

In the OGP the only way maps will locate you is with the GPS and not the WiFi, I have worked settlings but unless the GPS is on and locked nothing in Maps will work from your location aspect?

Nope

Nope, I think it's the problem of your rom. Try another rom. I have experienced this once and had the same thought until I flashed another rom then I could locate easily with only internet connected

I have not unlocked it or installed a new ROM,I noticed it out of the box.Was concerned if I had defective unit

I have the same problem... I just switched from the iPhone 4s to the LGOGP and the GPS is wacked out of the box. Not sure what to do about it... I just rooted and was going to flash a different rom to see if that works... if anyone had the same issue and knows a fix, let us know.

Same issue with mine.

So, you guys are saying that you can't get a lock without the GPS on?
Personally, I always leave the GPS on. I haven't had any issues getting a lock.

Help! GPS can't lock on!

I just bought another HTC One M8 and I noticed that the GPS can't ever lock on to my exact location. I downloaded GPS status & toolbox and it just stays on "finding location"
Any ideas? I'm running out of options and I'm thinking about just selling it and buying another M8.
I'm starting to think maybe its a bad GPS antenna, does anyone know where the antenna is inside the phone?

Ruu the phone 4.4.4

Go to Google settings app and make sure location history and access to third party apps is enabled.

I had the same problem on stock rom, I thought rooting and flashing a different rom might fix it but I didn't. I'll try RUU when I have time

Bump

I'll give this a bump because I've got the same problem. My GPS performance is TERRIBLE.
The phone will only lock with a clear view of sky and about 90 seconds of time to first lock. I've used GPS Toolbox and downloaded AGPS data and it doesn't seem to matter. If I hold my hand over my phone I lose a ton of the GPS satellite locks.
I can have the phone locked to 13 satellites and move it 2 feet over inside of the car and it loses nearly all of them immediately unless it has a clear sky view. Never had this issue on any previous phone.
Anyone have any input? If not, I guess I'll get this one replaced too...
Edit: Sprint HK Edition 100% bone stock, updated

Gps failed

HI, exactly the same problem now. Before my gps on the M8 used to lock on inside my house. But on a recent long drive whilst using the gps, charging the phone, and having the phone in snug holder it must of overheated.
Now it won't ever lock onto any satellites. Though it can see plenty. Have factory reset phone and no change.
Thanks

Hello
I have the same problem.
View 20 satellite ... but no connection with them :/
Any idea how to fix this ?
