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 ...

[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?

Again the GPS problem

Howdy,
So I'm another user having problems with GPS on my HTC Wildfire. I tried pretty much everyhing. Flashed all different radio versions via Recovery, fastboot and Android Flasher. Also I installed the agps patch. None of these solved my problem.
Before doing all this I had no GPS status bar icon at all. Now at least I have an icon showing me that he is constantly searching for GPS.
I also used GPS Test to clear and update AGPS but no luck.
Finally I tried several custom ROMS, from CM, to Splashmod and rempuzzle and all of them have this problem. So it's ROM independent.
What else can I try?

Fasterfix and gps essentials are the 2 apps that helped me fix my gps once.. and i had even used the agps patch by crypted for more accuracy

If you did all the above really clean - I mean with formatting/wiping/factory resets etc. it could also be a hardware problem in the end. But from my experience there are just a lot of pitfalls why solutions won't work.
The fact that you didn't get the icon show up before but now it does looks to me that it's not a hardware problem. My suggestion would be to reflash either the radio and the ROM again - but as clean as possible.
- look into "The Complete Wildfire Index" thread (in "General") pick the radio in the middle and flash that first
- do a clean wipe of at least the system partition, cache and dalvik-cache (I also do "format system" and sometimes a "wipe all/factory reset" to be sure and it couldn't hurt to wipe data also - your decision)
- flash the ROM you want to use
- flash gapps
- reboot and look what it does (this most likely won't do at that point)
- flash the newest of the 3 radios afterwards and see if this helps
--- Edit --- to flash two different radios is a dirty trick to remove leftovers or problems because wiping or formatting doesn't touch the radio --- EDIT ---
For testing GPS I suggest GPS Status from the market (best tool in my opinion). You could delete ags data as well with it.
The agps patch (I'm using it too) is just for optimization (to get faster responses) - it won't help if your GPS doesn't work at all.

Hello guys,
I finally resolved the issue and realised that GPS was working all the time well. However, I always tried to search for a signal inside a building in front of my computer and was not aware of the fact that the signal might be too weak to be received from within inside...:silly:
Anyway, the flashing method apparently did the trick!
Cheers

[Q] Help: Gps not working as it should.

Hey guys,
My gps isn't working accurate.
First off it worked pretty good but when I changed to a custom rom (android revolution Hd) it didn't anymore.
When i use google maps, it takes a damn long time to get a fix on my position and when it does it stays accurate for about 5 seconds and then it starts to change to a street next to me then to another side... etc. . Also when i am standing still it jumps for my location to 50meters ahead of me and behind me, changing my speed to 20km/h ... I think you get the problem. Also the same problem on navigon (navigation software) it is constanly rerouting me because of the inaccurate position. So its not an application issue.
I flashed the rom as it should be, with boot.img through fastboot and zip file in cwm. Except for the gps there are no other issues.
Then i flashed the original rom in cwm with boot.img in fastboot, still the same problem.
I then tried CM10 and it became even worse... every 20 seconds it gave me a position update in maps and with navigon there wasn't even a update because it couldn't get a fix.
And i also used fasterfix on every rom except the original one (not rooted) to set my gps to europe.pool.ntp.org or something like that...
Now i am trying to revert to android revolution HD but first my battery has to be charged above 10% and it goes damn slow because of the bricked boot (made a mistake while changing form CM10 to And rev HD) Can't flash the and rev HD yet but does somebody in the meantime know a solution ?

Somebody ??
Could it be a problem with the kernel ? because i didn't flash one separatly

Does somebody has a solution ?

Unfortunately, I also have the same problem with rom coredroid and igo primo aid to some expert please
thanks

I had the same issue when I moved from Stock to the Modaco Ir5 Vanilla ROM, my GPS didn't even go as far as finding my location inaccurately, it didn't work at all. Hence I couldn't use my maps/navigation.
I am now running the Slim Bean ROM and everything is working great. I am no expert, but have you always done the usual 'full wipe data > clear cache partition > clear Dalvik cache' while flashing new ROMs?
For your charging issue, maybe try this? http://forum.xda-developers.com/showthread.php?t=1646135

My phone is now allright but you i'll try the rom you are speaking about and see if the gps works better.
and... Also tried another kernel (eternity) but it still didn't work

I had this issue and had it fixed after sending my phone to service 3 times.
The first time they only did a reset, didn't help.
Second time they changed the wifi, GPS module, didn't help.
I sent them a recording of the problem on the third time. This time they changed the motherboard and it finally got fixed.
Remember to tell them that the issue is specially visible when GPS and WiFi are both on.

[Q] Problem JellyTime 4.2.2 on HTC DHD

Hi everyone!
I have problem with JellyTime on HTC DHD.
First I install JellyTime 4.2.2R7 into phone. The bluetooth not working.
After then I re-install JellyTime 4.2.2R9. The bluetooth ok, but gallery can't play video. Error text "Can't play this video"
--> Finally I re-install JellyTime 4.2.2R8. But the same, can't play video (open a video, waiting a long time and it still not working)
I also wiped cache and data and flash again.
Can everyone show me resolve this problem. Thanks so much!

Alo, anyone know this problem.

Hi,
I installed JellyTime 4.2.2 R8 a few days ago and never tried to play a video file on it before seeing your message.
I just put an .mp4 (720p) on my DHD and opened it with the integrated Google video player. Everything seems to be fine for me on that point. I can go forward and backward without any lag.
I tested also 3gp files, recorded with the camera and it works fine as well.
If you do it another way, could you give more details about how you proceed? I'm interested in checking if it works. And it can be handy for people to help you find a solution.
By the way, do you have any issue with GPS on JellyTime R8? In any case, could you indicate which radio version you have and if your DHD is S-ON or S-OFF?
GPS is not working on mine (no notification-bar icon, no fix), my phone is S-ON and radio version is 12.65.60.29U_26.14.04.28_M.

Apparently, flashing the radio ROM can fix it. But need to be S-OFF and it is more risky than just flashing the OS.
The ICS ROM you talk about has Sense, right?

yes it does...i read about flashing a new radio too..but yes basically it must be s-off.
I'm still researching. I'll tell you if i have any news.

Ok I solved doing this:
- Install this ROM (full wipe first) from herehttp://forum.xda-developers.com/showthread.php?t=1382235&highlight=zip full stock version.
- Then check that the gps works with gps status
- Go in recovery, do a wipe data/ factory reset
- INstall the JB R9 + gapps
Hope you can fix.

I saw a few posts talking about that procedure, but it looks so weird that I couldn't believe it! xD
I will try this week-end and let you know.
EDIT: And by the way, you still have the same radio ROM? It just flashes JB to Sense, activate the GPS from Sense and flash JB back?

It fixed my GPS issue as well! But how it solved it is still a mystery.
I did it almost the same way as you did. I explain it behind in case it can be usefull for somebody else experiencing GPS issues:
Reminder: being S-ON, do not forget to flash boot.img from the ROM image using fastboot.exe !
- back up of JellyTime R8
- from Recovery:
-------->full wipe (data/factory resest + cache + dalvik)
-------->restore back up of my previous Sense ROM (the one that has been installed after using HTCDev-like tools to root/unlock/S-ON the phone)
- reboot on the Sense Rom and activate GPS and check status using GPS Status & Toolbox (can take several minutes before getting a fix signal)
- reboot in recovery:
-------->full wipe again
-------->restore backup of JellyTime R8
- reboot and finally activate GPS using the icon bar or going in parameters (the GPS icon should start blinking) and check the fix using again GPS Status & Toolbox (or whatever).
Thank you again Icifide ! :laugh:
