GPS problems remain

hi there @all
I have a semi serious issue on the Ace (Desire HD)
it is one of the GPS kind of nature
Here is what is going on:
1. GPS worked fine
2. flashed ENG-hboot and it still worked fine
3. then flashed CM6 everything fine
4. CM7 nightlies (fine at first but then broken)
5. CM7 all I flash seems broken (the final 7.0.3 too) and I do not wanna leave CM7 -.-
now GPS seems to be broken, a lock takes >3-4min and the accuracy stays >20m
even the long term under open sky method does not fix it
and even erasing the EFS-Parttions does not fix it either
I tried different radios with their corresponding RIL-files
I tried GPS-Tools and erase A-GPS data and redownload them
nothing seems to fix the problem
the signal of the sats comes in strong and clear but no defined fix appears
my Milestone gets to 4m accuracy in about 15sec and first fix usually in 5-7sec
the bad thing is, that the Desire HD is not usable for navigation this way because Google Nav wants a better fix to use the GPS-Fix
anyone got this problem too? and got it fixed?

No idea, updated mine to Gingerbread using the manual method and GPS stopped working altogether. The GPS icon flashes up in the status bar but no fix, no satellites visible after leaving it for an hour
Tried the A-GPS delete and download with GPS Stauts, also tried GPS Test and nothing sees a single satellite.
Might try putting a the stock 2.2 ROM back on and see if that fixes it. Maybe something to do with an incompatible radio that came with the Gingerbread ROM?

Did you try AngelDeath fix for gps.conf here: http://forum.xda-developers.com/showthread.php?t=953630.
But be carefull, because the zip provided in the link (ftp://xda:[email protected]/) are for ext3 roms, and it will not work as such for ext4 roms.
If you have an ext4 rom, you have to unzip first and then manually with root explorer, copy past the gps.conf file => /etc/ in replacement of the existing one.
Don't forget to give all read/write permissions according to the original gps.conf file.
It works great for me reducing the first acquisition time from 1-2 min down to ~20 sec.
Enjoy

I had to send my DHD back on warranty due to a malfunction gps module. Htc replaced the module and everything has been working perfectly after that! (remember to turn it back to stock before returning it)

i had to pop my gps cover off and make sure that the prong's were seated properly worked alot better after i done that!

Hi,
i've got the same problem i think. Quoting myself from the Leedroid-thread:
---
Only one thing doesn't work properly for me: GPS.
On stock unrooted 1.72 it was fascinating how maps showed my exact (1m off eventually) position immediately when i left the house.
Then rooted, Leedroid (froyo) the same accuracy, tried cm7 rc4: gps-position jumping around, no lock etc. I restored my Lee-froyo-nandroid-backup, but gps stayed broken even after nandroid restore.
Tried cm7 stable again, still gps sucked, so i decided to use ruu 1.32, unrooted, s-on etc, DHD like fresh out of the box. GPS again was working perfect.
Now rooted again (couldn't let my fingers off of it ), used the leedroid 3.02 GB: GPS jumping around again, at least a little bit better, sometimes a 7m accuracy.
I always and ever do a full wipe before i flash a rom, never restore via titanium etc., installing everything fresh from the market. And i use the recommended radios (flashed via the Radio flash tool), check all checksums etc, tried on every rom different radios, fasterfix, gpsfix, loaded a-gps data etc.
Could it be a GB-issue exclusivly for my device as most people seem to have no probs with GPS on this rom or on cm7 stable ...?
---
Meanwhile i tried the new Android Revolution Rom, GPS still didn't work, tried flashing RILs, didn't help either unfortunately.
Currently i try out the new Leedroid and formatted to EXT4, tomorrow i'll try out GPS again.

@Nasobem
i am completely with you on what you say, i remember GPS being spot on when i first got my DHD, since rooting no rom/radio/ril has ever given me consistantly good GPS, i have had days where it seems to work fine, then nothing.. very frustrating..

Very true colonel, it's really frustrating ... An hour ago i was trying out GPS with the newest Leedroid kernel. I've been really excited, because i got a fix inside the house (after 5 minutes waiting time), and it has been very accurate. I went outside with a big grin on my face, took a look on maps and ... nothing, no fix, GPS jumping around even after 2 minutes. Finally a fix on a position 20m off. As a little additional gift from the God of the Smartphones, now when I'm holding my phone to the east, it's showing north sometimes.
It's strange that there doesn't seem to be a solution for our GPS problems as it is working on stock rom ...

Yeah, I can second that. I went as far as soldering the pads on the plastic cover to make sure there's metal that can connect to the prongs/springs. Mine had small black pits in them, probably too thin strips so the prongs weared a hole in them.
I've made a youtube clip on it http://www.youtube.com/watch?v=7qm_z65LA8k

cool. where did you get a new gps cover from. i took the cover off a while back and it worked better for a bit, but would like a spare cover if im going to solder it.

GPS is messed up with Gingerbread, I found the problem was the GPS.spade.so file in: system/lib/hw. The only Rom I found to work was the latest cm7 nightly. 80 onward.This has a modified gps file. I'm surprised you're having problems on CM7 maybe try clearing the efs cache;
http://forum.xda-developers.com/showpost.php?p=12764930&postcount=1
Or put the SD card in a card reader and format it. Reinstall Rom doing a full wipe.
PS.noticed you already tried wipe efs. When trying the later nightlys a full wipe is required.I also read a lot of Cm7 users were substituting older GPS files to solve the issue.

thanks i will give it a try, but i can also get a fix when i press the gps cover. mix of problems i guess..

May i ask how to wipe efs data on DHD? I tried AngelDeath's fix and replacing the conf file with another one, but didn't help ?
Can i just use the vision_wipe_efs_01.zip or should i use the dd method (brick risk)?
Thank you

I bought it on ebay (item 140529713185), not the easiest to find unless you search for the "correct" name "gps antenna" yields no items...
They often call it "flash cover" as the camera flash leds shine through it, so variations on that will give you a decent list of items.

Funny, I was just going to open a thread like this one.
I'm on ARHD 5.1.7 and I'm experiencig the same issue as the OP (I used to have the same also previously on ARHD 5.1.3).
GPS doesn't fix at all in google maps, the only workaround aI found to be a little effective is to open GPS status (which takes from 50 to 70 sec to fix anyway) before using google maps, but still the precision remain at 40 m and fix is not very fast.
I tried all the solutions suggested in the question 14 of ARHD first post but with no improvement.
The only thing i wasn't able to do is that, which I understand to be the same solution suggested by michelD

Sorry for such a noob question, but I don't get how to give/get the permissions to overwrite a file in /etc/ directory.
Everytime I tried to overwrite the file it remains the same.
Can someone please provide me some detailed information?
Thanks in advance

I had the same problem on CM7 but I downloaded FasterFix from the market and set the pool to my location eg.UK. Now my GPS locks on in a few seconds.

Ok, I figured out by myself and I succeded in overwrite gps.conf using "super manager".
Now the GPS finds 2 more sateliites than before (they were 6, now 8), but the fixing is now worse than before, sometimes taking more than 5 minutes and still I can't get any fix directly into Gmaps.
What amazes me the most is that my previous phone - the wildfire - used to fix a lot faster (no more than 15 sec.).

I've tried several roms now:
CM7.0.3
Stock-rooted Gingerbread (2.36.405.8)
leedroid 2.2.3
Raidroid Stockify 1.72.405.3
I did wipe efs data, wich didn't work, then tried fasterfix, then tried gps status (I read that gps status sometimes can cause trouble)
Sadly none of the roms GPS worked for me, even as close as possible to one of my last working configurations, Raidroid Stockify
Now i went back to original unrooted stock again, made S-ON, just to test it out, this time to 1.72. And GPS still sucks. I'll have to send it in for repair i think.
Something was surprising: When i had shortly (for rooting on s-on-reasons) 1.32 on my DHD, it showed two WLAN, wich none of the roms ever showed (from a large, far away city hall, very weak signal). So it seems that for me the strongest, best reception is on 1.32, wich is the ONLY software that can deal with my obviously bad GPS/Wlan hardware - sadly this doesn't help me, because videorecording is lagging on 1.32 etc ...

Cm7 GPS

Just installed cm7 on my wildfire however GPS is not working. How do I get it working (and how do i get the HTC ime back)
Sent from my HTC Wildfire using XDA App

Reflash the radio. Radio can be found in the WildPuzzle thread (Or in my Index thread). Also, there's a thread in Dev having the HTC IME, which works on CM7. (No Enter key though)

Ok. Also how do I get the notification led working

I don't know about 3rd party apps, but, Notification LED works fine for me. :/

Hi, today I did the same...and I've the same problem: GPS icon does not appear, i try to install Radio_13.55.55.24H_3.35.20.10 in recovery mode (recovery-clockwork-3.2.0.0), but it says "Amend scripting is no longer supported"
Where can I find a working package to fix GPS?
Thanks, kind regards.

Install ROM Manager (Or, it is already installed by default). Open it, Select "Flash ClockWorkMod Recovery". It will install CWM v2.5.0.7 on the SD Card. (Technique called FakeFlash). Then, select Reboot into Recovery from within ROM Manager. This will take you to recovery 2.5 which will support flashing the Radio.

Hi I've the same problem. I have latest CM7 stable build. I installed the latest 2.5 clockworkmod, and flashed the latest radio package. Still no GPS on my Wildfire Any ideas anyone?

Flash the radio package which ends with 19.25. Also, in CM7, you do not get the GPS Icon on the status bar as soon as you turn it on. Only when you open an app that actually uses it, will you get the icon. (Apps like Google Maps, Navigation Apps etc)

yep, that also surprised me
Do you know if there is actually a connection when the image is not shown? (when GPS is not used). Or will the battery only drain if some program is using the GPS? Meaning it would be okay to just leave the GPS option on all the time

I think it will still drain your battery out, even if you don't use an app and keep GPS on. I was testing it, and didnt get a lock in my location, so, closed Google Maps and kept the device as it is. But, the battery log showed the whole time as "GPS on"

Thanks 3xeno. 19.25 version radio worked for me. Strange, as it wasn't the latest!

hye my gps still not working..
i have try these steps 1. Go back to your stock froyo ROM turn on GPS and then open Google Maps. Let the GPS find you, wait for a few mins and then go back to your intended ROM after clearing and formatting the data. Have tried this method on 3 cells ( My friends were the victims!!!) and it worked perfectly!!
but the gps still cannot capture mylocation...
so what to do??
should i try flash the radio but my baseband version is already 20.10..

Reflash 20.10. Or, you can try 19.25 also. In some cases where GPS on 20.10 failed, it has been known to work with 19.25

yeah !! thanks...
flashing to 19.25 seems to solve the problem..

[Q] GPS not working

I just installed this http://forum.xda-developers.com/showthread.php?t=1458749 and my gps doesnt want to work anymore. when its turned on and google maps opened it doesnt even show the icon. i tried some other programs but gps wont work in them either.is there any way to fix this problem or i need to download another rom?and another question:is there any way to fix 2.3.7 android camcorder problem?
sorry for bad english!

This happens very often
You can try 3 things when this happens... like a month ago it happened to me S-FFing my Wildfire
Some people says that Flashing the last radio for the wildfire (3.35.20.10) solves the problem: http://wiki.cyanogenmod.com/wiki/HTC_Wildfire:_Support_Downloads its very easy but you need 25 or more battery when u start the process because if it does not finish u can brick your phone.
You can also try with this patch for the GPS, also makes it faster http://forum.xda-developers.com/showthread.php?t=1447591 (x3 trunk Download the Google Specific) Just flash it
What it solved my GPS problem was to Install my original HTC Rom and activated my Gps, you should enter google maps and wait until finds you. leave the Gps enabled and restart your phone in recovery. Wipe everything (Data, cache) and install whatever Rom u want

I already have 3.35.20.10 radio and i already tried to flash agps patch but i havent tried last thing

It's slow and sporadic even with the fixes. The offset is usually at the same spot on my map.

another option is to create a nandroid backup the, flash a ROM with known working GPS, turn on the GPS on that ROM and let it get a fix on your position, leave the GPS on then reflash your backup. GPS should now work fine

Thanks arkoze and r30orozco!And is there any way to fix camcorder force close?

[Q] Radio issue, flashing does not help

Hi xda community, this is my first post here, although im am following the forums for a while now. I have also read similar threads, and googled for about 3 hours now, and still couldnt fix the following issue:
I installed CM7.1.0.1 on the standard HTC Wildfire, and the GPS doesnt work. the radio version was 3.35.20.10, and I downgraded it to 3.35.19.25 but still nothing. problem is i cant get the signal, and there is no satellite icon on the status bar. like nothing is happening. I reverted the radio to 3.35.20.10 but still nothing. what do you recommend? are there any special methods to fix the issue? I did it by downgrading the recovery to 2.0.5 or something and then istalled the zip from the sd card.
edit1: downloaded GPS Test (i am not advertising, some1 might find it useful) and got the icon on the status bar. ill go and test it, and will update the post.
edit2: seems to work, found 7 satellites in 3 seconds with GPS Test. turned off wi-fi, started a popular navi app, locked signal after few seconds. maybe ill set it to solved?
Long story short:
Downgraded Radio
Upgraded Radio
Downloaded and started GPS Test, outside
Found satellites, icon is also there
started a navi app, locked signal

Same problem, still no solution though...
I had, still have the same issue. And I have already tried all that you have done in vain...
Any one else had that issue?
Thanks

Flash a sense based rom, turn on GPS, open Google maps and leave it to get a good fix. Without changing anything pop out the battery and then reboot to recovery and either restore a Cm7 backup or flash the rom again.

Thanks. Trying that now...will edit after.
EDIT: Can't find a proper Sense based ROM. Tried REMPuzzzle but phone stuck on HTC Screen. Downloading DK CustomROM now... If anyone knows whether there is a safe flash Stock ROM around, please do tell. The link in http://forum.xda-developers.com/showthread.php?t=1275680 is dead.
FINAL EDIT
@saadislam and @LucidSomnia: I know, but when I said it takes time, I meant like over 2.5 hours, I think there might have been something wrong in the zip file.
Anyways thank you for all of you there in XDA Community for your support. I finally managed to sort it out by using Scratch0805's advice above and it works fine now.
**The only issue I got was to find a Sense-based ROM. Everything I tried either had an error, could not install, corrupted or took TOOOO LOOOONG to load. So here are the steps I have taken:
1. I used RUU to start over with a Stock ROM. [ available here: http://forum.xda-developers.com/showthread.php?t=1275680&highlight=rom ]
2. Re-root [ http://forum.xda-developers.com/showthread.php?t=1145035 and/or http://forum.xda-developers.com/showthread.php?t=1365159&highlight=rooting+guide ]
3. Flash new Radio (20.10) since rooting goes back to 19.25 or 15.35.
4. Install and run GPS Test (on the Stock ROM)
5. Allow it to lock on couple of satellites.
6. Pop the battery out.
7. Boot into Recovery.
8. Use a Nandroid backup (or you could install a fresh one)
9. Enjoy GPS Working again!!!
Thank you again XDA Community!

Are you sure the radio was reflashed... I am saying this because when I tried to flash radio via recovery, it completed and I reboot.. but Gps wasn't fixed.. I rechecked the radio version but it was the older one so basically radio wasn't flashed...
So I went on to flash via flashboot.. this time all process was completed and Gps worked fine afterwards...
Radio version 20.10 is the one which has always worked for me...
And one thing more.. Rempuzzle Rom takes time to load first time...

Wifi 'error', Bluetooth & GPS dont work. Plz help me!

Hi,
I have big problem with Wifi, Bluetooth & GPS on my phone.
10 days ago, my phone work very great with ViperX 3.3.3 (stock kernel of the ROM). But, when i trying download the Maps offline via Wifi Network (5% downloaded), wifi automatic turn-off, i try turn on it in the Settings, it show 'error' message (Bluetooth & GPS also not work, cant turn on it). While Mobile network work fine.
I was flash more ROM another (stock kernel), & custom kernel (include module), with full wipe & erase cache. But still not fix it
Is this a hardware issue? Can i fix it for myself? HTC's service in my country is bad i dont want send my phone for them.
Plz help me!
Many thanks for read my post.

Which rom did you try?
However, is a kernel issue and i don't think this is an hardware issue.
But is strange...

I tried more rom ViperX, ARHD, Balde, MIUI, ... (all full wipe, erase cache & stock kernel), i also tried flash a custom kernel (include module) when stock kernel dont fix my problem, but still not fixed!
And, i think if it is a kernel issue, i have that problem when my phone boot a first. As i said, i have problem when my phone using normal (with wifi, bluetooth, gps on), after i downloaded a Map offline 5%, all is down
Thanks you, for reply this thread!

And mobile network, 3G work fine. If is kernel issue, mobile network fail too, i think so!

Usually, the error message of wifi, is a problem with kernel because i had this error yesterday with my rom for evo 3D.
I reflashed the kernel and all works fine.
So, it's really strange that may be an hardware issue, did you try to flash a CM based rom? Or AOKP?
And did you try to open maps app?

I tried this rom http://forum.xda-developers.com/showthread.php?t=2013506, but still not work. Why do you think CM based rom or AOKP can fix this problem? i have not tried it!

I was open maps again, after have this problem, and i know gps not work (dont see gps icon in the status bar).

R: Wifi 'error', Bluetooth & GPS dont work. Plz help me!
Because have a different kernel respect sense rom...
But, if you've tried this rom is possible that is an hardware issue, but i don't know why and how did it happen
