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

Follow the instructions in this thread. Flash the updater and then the efs wipe tool through recovery.

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.

GPS works for me (screen shot included)
I don't use the navigation much but if I understand the program gpsstatus, it is working for me. I have used CM7 RC2 and RC4 (which is what I am on).

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] no gps with Cool Sensation on Desire

Hi everyone,
I installed this rom a few days ago and one thing for sure is that it kicks ass (except for battery life, thanx to sense 3) BUT, because there is always a "but", I have no GPS anymore.
I never had troubles before with different roms, last one was crystal kingdom, but I can't activate GPS from widget nor directly from the parameters. If I click the widget for instance it says it's ok almost immediately (always took few seconds when it did really activate the thing) but GPS is still down.
I tried many things, several radio, RIL, reboot without battery,sd and sim but no way...
I've found some "fixes" around the net but seems not to be for Desire so I prefer asking before trying some things I'm not sure.
Phone is HTC Desire with 8go class10 sd.
Thanx

It's most likely the rom. It's prob still in beta and buggy as hell.

ok i've found a way...I go to Leedroid ! lol
So it's a ROM trouble, I noticed that the /lib/hw under Coolsense is gps.htcleo.so. As everything is ok with Leedroid, I tried to get the gps.bravo.so from it and push it to replace the one from Coolsense but unsuccessfully because of read only file.
So I stuck with Leedroid, which is a lot less buggy than Coolsense.

I have tghe same problem. I upgrated to latest Leedroid also but no luck. GPS in not fixing. I tried gps test and it doesn't seem to find any satellites. I previously tried several roms and radios but none worked. Any help?

[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.

I can not find the gps-module on Ebay, can you help me?

same thing happened to me after upgrading to ICS rom and since am not using it that much, just ignored it and wait for the devs to fix it...now waiting for the wifi fix of blackout ICS
