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

Already testing... I was already getting good GPS results on the EL29 ROM I built (even indoors). This mod is really just another gps.conf edit.
I installed the mod over an hour ago, reset agps data, rebooted and got a pretty quick lock (indoors) immediately. I just tried again and it's not getting a lock at all. I think I'll go back to the original gps.conf and see if it locks properly.
Update: After reverting back to the original gps.conf, clearing agps data, and rebooting, I got a lock in 5-6 seconds. I think part of the issue is that this is now hitting "derekgordon.com" instead of the regular GPS servers. This mod was sent out to the interwebs and I'm sure there are TONS of people installing. I'm not sure if the server is overloaded or whatnot, but I don't want to rely on someone's private website for my Navigation and other GPS needs.
Code:
NTP_SERVER=ntp.derekgordon.com
AGPS=http://derekgordon.com/gps-files/bin/xtra.bin

i already get decent gps as well but this mod has me curious.
i totally agree with you about not wanting to rely on someones personal server.. though only v3+ includes this server. there are older mods that rely on qualcomms servers.

I tried this mod (V3) and it made no difference for me.. I'm afraid my GPS problems are hardware related, I've tried almost every 'fix' available.

Well it probably has to be manipulated to work with our device. The file is for the international sgs2

...i wish u didnt say that...because my gps is fukked...i was hoping this patch would fix it but if i end up being in the same boat as you where its a hardware problem ill just take it into sprint...i havent done it yet partially because i am hopeful that i can fix it too lazy to go and scared they r gunna find out i rooted my phone even tho ill rest it back to stock

I'm getting my hardware replacement this Friday. I've done everything from scripts, to gps drivers, nothing is consistent. Even reverting back to stock didn't do anything.
Hopefully it will fix it.

I tested this today. Before the fix I couldn't get more than 3 satellites in GPS Status, after the fix I got 9.
Also noticed that while navigating I could get a lock in under a minute instead of 5+ minutes before the fix.

Mine is stuck on roaming after flashing, weird
Edit: fixed now, no idea what caused it but fine now
Gps crazy fixed now too

loaded the new config file last night and day later it still won't get a lock. i guess this mod isn't for me.
edit: after few reboots it gets lock in under 5 seconds... hope it stays that way

Anyone know if this patch helps at all on ICS ROMs?
-Sent from my CM9 E4GT using Tapatalk

Is it possible for someone to upload the original gps.conf ?
I lost mine after trying many different modes, to get the damn gps working lol.

Here's my stock gps.conf from /etc/

It may help some but I know that some of the phones have bad gps chips in them. My first one did. I had to get it replaced in order to get a gps lock. The first one I had would never see more than 1 sattelite and never lock. Nothing I did or that the sprint techs did could change it so they swapped it out for me.

[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.

[Q] No gps with Android revolution hd rom

Hello there,
As the registration video pointed out to me that i'm a noob i have noob question.
Im running Android Revolution HD 6.3.3 By mike1986
with these radio thingies.
12.65.60.29U_26.14.04.28_M
But my gps isn't getting a fix. What is wrong with my phone settings?
Hope to hear from you.
Greetings
Youri

Hello.. Maybe try flashing the AGPS patch from this thread.
Here's the direct link... flash that through recovery and see if it works

And if you are having crappy GPS accuracy once you lock, your best bet is just to find some way to get a solid connection from the GPS antenna to the motherboard.

Question is if you've had problems with gps fix since flashing Mike's rom or has it happened after a while.
Next question is what navi software do you use.
I tried two navi programs: Google's and beta version of Automapa (although beta is closed for now)
GPS always gets fix after couple of seconds. With Automapa it is also very accurate. Google is worse than Automapa but still quite good.
Both programs were running on ARHD 6.3.1
Anyway I'd try reflashing with full wipe again. Or maybe try newer (or older) version of ARHD?
Regards
Rafal

There are several possibilities:
1) environmental - try again outside, in plenty of open space. Try with & without your case, if you're using one.
2) config: download FasterFix from the market and choose your preferred server (there is a preconfigured list, but you can also type your own in: Spain is es.pool.ntp.org France is fr.ntp.pool.org etc) also check out GPS Test, also from the market, and you will see exactly how many satellites are in view etc.
3) hardware - bad connection. If you can't get a result from 1 or 2, well maybe there is a bad connection (the GPS antenna is around the flash). This is unlikely, I'd say.
A reboot may help to clear the cache - as suggested above, a superwipe is the way to clean before flashing a new ROM. You can also clear caches from Recovery.

First do some testing before install any patches.
Go out under clear sky and after activate gps sattelites from settings, download and run from market the Gps Test apk.
Write us the results here.How many satellites and after how much time did you get.

I`maar also noob without same issue. Same rom and same radio.
Before flashing, gps worked flawless, after flashing no more fix.
Even the quality of the signal for calling is nota wat it was.
Tried 3 navigation apps, open area,... nothing works.
I really Need the gps, so i`m thinking of unrooting if there isn't aan sollution.
Or could this be solved by flashing an stock rom ? Any tips or hints are welcome
Thanks in advance!

Personally i reccommend this http://forum.xda-developers.com/showthread.php?t=1318892
it seems a bit risky,but it shouldnt be a problem opening the flash case. Im not into soldering, and im afraid of burn motherboard,so i just pulled up the golden springs a bit,cleaned with alchool, an voilà! fix in < 10 seconds with < 20 meters precision.
hope it helps.

It seems to me that if gps worked stock, the hardware is ok

Yeah try the Rom in my signature its awsome :thumbup:

I had problem with my GPS too. It's doesent a rom or radio problem. In other thread it's show how to hardware hack the GPS under flash cover of our dhd. I won't hardware hack so gently push down the flash cover. Go out and GPS status and gmaps fix in less then 10 sec.
Inviato dal mio Desire HD con Tapatalk 2

i'm noob with rooting phones, but not with pc's or other electric equipment.
If i say gps worked FLAWLESS on my stock DHD, how can my antenna suddenly be defected after flashing a rom?
I even went to open field with NOTHING in a 500m radius
it has to be something software....
i'll try to flash other rom like someone suggested...
already thanks for the replies!

check if GPS is broken?

I have the same problem! My GPS is running but it cannot find any sattelite!
Is ther any method to check the GPS if there is a hardware problem or a software problem?
Maybe there is a logging like "logcat" for GPS which i can check?

I'd recommend trying the app Faster Fix. You select your region, and it sets the correct GPS configuration data. If that's the issue, that app will solve it.
Also worth trying the app AGPS Inject, which downloads GPS assist data when opening gps apps like gmaps.
Also recently removed the letters "supl" from the APN type in the data access point settings. Resulted in a faster fix.

Thank you Swell6 for your tips, but nothing helped!
I think it's an hardwareproblem.
Does someone know where in the phone the GPS Module is sitting?

With the dhd there's a known hardware issue with the GPS antenna, which is part of the black plastic led cover. Over time it can lose contact with the main board, and sometimes just pressing it in can fix it. If it needs more, there's loads of posts on what can be done. Worth a try!
