BELL Legend and SLOW CRAWLING GPS Lock - Legend General

Fellow Bell/Virgin Legend owners...
Are your GPS Lock times fast ( less than 30 secs )? Are you stock or Modded?
I'm having very erratic lock times...( the few times i get a lock ).I dont recall being that long when i was stock 6 months ago... but then again may be i wasnt using it as much as i am today....
im on blayo .84, tried different gps.conf i found on the net... sometimes they give you the impression that it fixes the problem for a while I've tried various combination, with wifi, data and without. Without any firm conclusion because sometimes i get fast locks ( less than 30 secs) about 10% of the time, 20 % average locks ( up to 3 mins) and 70% worst locks ( 5- 20+ mins).
Since i won't always enable Data, i've decided to test without data . Use GPS Status to test the time it takes to lock, Always Reset GPS Data after every lock, then right away use Fast Boot (from market) to flush all memory/cache
but now i can consistently test without data or wifi that:
1. if i use gpsstatus to test lock times and Reset GPS data, it may take from 3 mins to 20+ mins to lock
2. Everytime after a test, i use fastreboot (from market) to simulate a reboot and flush all memory, right after i use gps status to Reset GPS
At this point my conclusion is GPS is not consistent... and is not working most of the time... the few times it may work but again after a long wait time... is when i have Data on... but i wont always enable data when im outside my local area.
The things i've encountered is that may be i am missing the /etc/suplrootCert from bell (when i try the gps.conf of a BELL because it seems to point to different supl server, and port... the other tweaked gps.conf...i have a relatively fast fix when my data is on
can anyone with stock bell or working gps, send me their config /system/etc/gps.conf and the etc/suplrootcert
im using radio 7.13.35.13 , kernel 2.6.32.17, build 3.15.405.3, android 2.2

did you try it at diff locations?
if my gps works slow or not at all i reflash my radio, but be carefull with that !!
can't give more tips tho.. sry

[Q] Getting GPS, doubts

hmm, i am new in this, and i wanna realy get GPS, without data plan in my HTC Vogue Sprint CDMA, i have read several diferent guides and i get confused , i am not verizon user, i Have NFSFAN 1.0, Radio 3.42.50, PRI 2.04, 2.31.coke
Exist any guide 100% functional?
What should do now?
GPS is built into the device.
You will have to find your own program to download to the Touch in order
to use the GPS features.
Usually if you have Data, you can download Google Maps and it takes advantage
of the GPS functionality.
Thread moved to General.
Based on your radio, you already should have a working GPS. If you are running NFS and would like to check if it is working, open VisualGPS or HTC GPS Tool (which I believe is included in NFS's rom). Set your COM port to 4 and your baud rate to 4800 (normally this in done in the program's settings) and try to get a lock. I will take a while for the Vogue to get a position lock. However, in the meantime, you will see several satellites pop up in the window. Just be patient for now, it will lock eventually.
i get MODE 2: Fix not available in sattelite tab, some times appear one red point at top north
Where are you located?
I'm up in WA state, and, depending on weather, can take a few minutes
to get a good accurate GPS lock.
Also depends on area too. If in the city - a little easier due to all the
cell towers around giving better location signals to help the GPS lock.
If out in the suburbs, can take longer for a lock.
If its a cloudy day (pretty common during the winter) it can take much longer for a lock.
To my me takes 5min in do lock and use Garmin to view maps

That isn't too bad. I have had my Vogue taking up to 15 minutes without getting a lock (spots tons of satellites but no lock)
had the similar problem just posted my fix in nfsfan rom post takes a while but worth it i didnt get no gps signal even try different prl and pri variation nothing added cabs nothing, had to relock it with iamcokeman .41 flash oem rom no gps unlock with 2.31 then flash wm6.1 then then flash nfsfan an works great (similar to "verizons gps fix" but it didnt help me had to use my own carriers roms) took me 4 days to figure it out but worth it get lock in less then 20 seconds using google and bing if u have any questions holla. currrent prl 60613 (which i got when i flash oem 6.1) and pri 2.04 (i intall it myself)
am in NYC fyi
@pabloq629
so, i should relock with icecokeman .41 then unlcok with 2.31 flash?
i have PRI 2.04 and PRL ID 01903
PRL ID 01903 where do you live is this for sprint because i try this with my sprint vogue this are the instructions http://forum.xda-developers.com/showthread.php?t=533639 but when i try it, it didnt work so i download the oem wm6.0 as my nongps rom which took forever to find then i used the wm6.1 with gps and done remember i still followed the same procedure i just used different roms it look like 4 to 6 hours to take affect i dont know why but when i started it didnt lock then after 5 hours it lock within seconds i just did this last night so far so good if need the cabs i have them just let me know and ill post them BUT REMEMBER I USED THE SAME PROCEDURE FOR VERIZON JUST USED SPRINTS (which is my carrier) roms or OS and READ IT CAREFULL . BEST OF LUCK
The Vogue GPS just plain sucks & I can't figure it out. One time it will connect in under a minute & the next time it might take 5, 10, or even 15 minutes to get a lock. I'll use the GPS to get to a job site & might be there for 3 hours. When I go to leave it could up 15 minutes or more to lock again. It's crazy. Now my Imagio lock within 10 seconds every time.

[Q] Would you like to help me fixing the GPS?

Hi all, i'm dealing with HD2 android nand installation since 3 days.
I've been able to have everything working like a charm except the gps... that damn thing doesn't want to work in any way.
It works correctly in winmo6.5, i tried copilot and the internal gps tool started seeing satellites each by each to end getting a fix in around 1 minute. Absolutely acceptable!
Android is a whole different story.
Gingerbread:
MDJs 2.5/2.6 it doesn't work. Tried changing libs manually, renaming, chmodding, fasterfix, changing the radios 3 times (2.15/2.14/2.12).. no way!
Froyo:
Installed a CleanDroid rom (basically a CM6.1 clean build), launched gps status and no go... wait! linked! from 0 to 6 satellites linked! is that normal?
Well, i was happy anyway... finished congifuring the rom, went out, tried again with Gmaps... searching... 5 minutes... 10 minutes... gps status says no signal.
Reboot, gps status, no signal.
Powered off the gps then on again, gps status fix in 1 minute (again, from zero to 6 satellites suddenly). Then i'm trying again now and it still acts strangely.
No go for 15 minutes, then it fixed (7 sats). Exit from GPS status, waiting 3 seconds, opening it again, 15 minutes, no fix... same exact position!
It's, in a single word, frustrating.
Currently i'm on Cleandroid Froyo rom, radio 2.15.50.04 (it came with stock HTC WM6 rom), magldr 1.2. All roms installed through CWM.
Any hint that could help me solving the only problem i get with this puppy?
Cheers.
Edit: forgot to say that i don't know if AGPS date are working correctly in GPS status, every time i try to download them it says "AGSP data will be downloaded as soon as there will be internet connection" (or something like that). It goes by it self that internet connection is alway up and running (3G or WIFI).
Updates: tried with miui and desire rom, same behaviour.
Reinstalled WINMO6.5 and tried a littlebit, it gets a fix in 1 to 2 minutes but i can see the satellites in the tool. After fix it keeps the connection.
Anyone of you can please let me know how is GPS status acting on your HD2s?
I've a nexus one too and GPS status starts showing stallites slowly, one by one untill it get a fix. The few times i got a fix on the HD2 it was suddenly, no satellites where showing before. Is it acting the same on your HD2s? I'm becmoing mad 'casue by the blueprints both HD2 and Nexus should have the same chipsets and the nexus is really really fast in getting the signal (with or without agps).
Another thing, since my HD2 is brand new (it came back from HTC for repair the 4th of jan) may it use a different GPS module? Is there any way i can check it?
Cheers.
Works fine with me,
MDJ 2.5 CM7
2.12.50 Radio
Fasterfix set to Netherlands. AGPS downloaded via GPS-Status.
Get a pretty quick fix, about 2 minutes.
Didn't change any lib, since it should work out of the box with MDJ 2.5.
Also, the first time a fix will take some time longer, so just wait till you get a fix.

Thanks but i already waited very long... 15 minutes on a balcony in the middle of an open street is too much, i didn't get a single satellite showing in this time!
The nexus gets the signal in 2 minutes without AGPS and after erasing GPS data. It also starts showing satellites after 15 seconds at worst.
The 2 uses the same rom (cm6.1 froyo) and same tools, tests were made side by side.
By the way, could you please help with my other question? Does your GPS status show satellites slowly or suddenly?
Thanks.
I have no problem with 2 hd2s, 1 running mdj 2.6 and 1 is running desire hd.
Sent from my HD2 Droid HD using XDA App
There is definitley a problem with the GPS, I have pretty much the same experience as the OP, sometimes it fixes sometimes it doesn't. When it does fix it suddenly has 6-8 satellites after finding 0 for 10 minutes.
Also some other guys reported this behaviour, it doesn't show anything untill it gets a fix. I think this is due to libgps which is probably still in development.
At least i hope! Today i gave it another try, went out in the middle of nowhere and had a 15 minute walk in around 30sqmt with gps status open and leo on my hands.
No fix...
Hope some developer may look at this and help me out understand what's wrong with my unit. Also logs say everything is working correctly... but it doesn't.
Did you try to reflash the ROM?
Also I get a pretty sudden fix of satellites, it will scan, and suddenly comes up with 5 fixed satellites of 8, it was also pretty quick this time. Less than 1 minute!
i flashed like 10 roms, some of them twice...
Some good news! It seems that using WINMO + SD Rom it works every time, it's just someway slow in locking the position and it doesn't matter if i just got lock or not.
Used Cope's gingerbread rom, first got fix with winmo, then with phone in the same position switched to andorid ad got a lock in around 5 minutes with GPS status, then i switched to Maps and got another lock in around 2 minutes. Not exactly fast but it's working at least! I don't know if it will become better with usage, i'll keep you updated.
In the meantime who was stuck as i was could give it a try.
Cheers.

GPS UK

right I have to know if its only me but even after editing the gps config file it still only works every now and then and even that requires gps status and tools? At the moment using WP7 and gps is lightning fast (fix etc) but switching back to android as android is most definatly superior in most cases at the moment. Especially the camera quality is bad and battery life is ok but better on android
Is there a rom with a WORKING gps not one that works under supervision? as I like to use the gps apps like maps and copilot etc
OK well just changed a couple things and now gps is working
I dont know whether Radio revision affects it but downgraded it to 2.12 from 2.15 and left my gps location as europe after clean flash and now getting a gps fix under 10 secs mass improvement to before (2 mins to never)
might try with UK ntp.pool settings, and see the results
Edit as you like, but < 10 seconds is about as good as it gets, don't fixit if it ain't broke!
well tried it anyways and it is even better >5 seconds is this a radio related. If so gotta write down this radio version for future reference
You get quicker fixes when you've already recently had one, I don't think a <5 seconds cold fix is possible.

This is intresting.
Is it possible to keep us updated in a couple of days to check if the quick fix is consistant with radio 2.12 ?
I think it would interest alot of people.
My phone was also with 2.15 previously, as willzrocking i experienced mixed result with this radio and long time locks in any case.
This morning i was encouraged by this post and gave 2.12 a try, unfortunately for me it seems tobe no go, it seems worst than 2.15 on my phone.
In the same road to my office (10 minutes by car) 2.15 was able to lock 1 or 2 minutes before i reached destination (not really usefull...), 2.12 was not able to catch the signal.
I'm going to try have a lock in a plain surface later on today and will let you know the results.
Cheers.
Still working good for me... I am using the Cleandroid Rom but even though the gps is now very good the network keeps dropping alot and sometimes randomly the H signal disappears and replaced with G sometimes until I switch between flight mode so think I am gonna have to sacrafice the GPS until I find a better radio/rom
I've just put on 2.12 here in the UK and don't notice any real difference at all
EDIT: ooh think i've now solved it for me!
I also have an Orange San francisco ( ZTE BLADE) and that always locks on GPS very quickly...
so i had a delve into the blade's gps conf and i notice a few parts were commented out that arent for my HD2.
the parts i just added/commented out are.
I added
INTERMEDIATE_POS=0
and commented out the following to look like this
#SUPL_HOST=supl.google.com
#SUPL_PORT=7276
Now after locking/unlocking the phone and rebooting i get a lock onto GPS in under 10 seconds every time, whereas before it was very hit or miss!
Out of curiosity, those who have problems, how many have the app GPS STATUS installed? i'm wondering if it is causing a problem too.
this thing is driving me crazy... as the gps is!
2.12 was worst than 2.15, then i tried 2.08, same as 2.12. So i did a roll-back to 2.15 and tried to put crunchie's settings into my gps conf.
Didn't notice any difference so i tried to remove gps status.
After reboot i made the following test:
launching google navigator 3 times, every time i placed the phone in the same position where i was sure to get good signals.
Between each tentative i removed the phone from its position, closed navigator, turned off and then on the gps, replaced the phone back.
It took 20 secs to do this operation.
I got a fix each time, which is good, but look at locktimes...
1) around 90" (good)
2) around 3 minutes...
3) around 4 minutes...
It seems like it doesn't save gps data previously scanned, every time it's like a cold start...
I really don't know if there is any way to fix this at the moment but i would really like to know which is the difference between my phone and yours. Maybe 'cause mine is brand new? (i received it the 4th of jan)
Very important for me too. So my parts:
RADIO: 2.15.50.14
ROM: MDJ's CyanogenMod 7 v. 2.6
COUNTRY: Latvia (EUROPE)
Actually this is the only Android build where I got any week GPS signal. Previously - nothing.
Well, on WM 6.5 GPS works extremely good and stable with the same radio.
I am using GPS Status (to download some A-GPS data, which really does not helps).
I live in Latvia, but my gps.conf was set to europe.pool.ntp.org. I was able to get some week connection today with a fix in approx. 10 minutes. When I changed my gps.conf to my country: lv.pool.ntp.org GPS stopped working. Will try now to revert back.
P.S. My friend with Desire HD also living in Latvia has north-america.pool.ntp.org, but still gets fix in about 30 sec. And changing gps.conf and downloading A-GPS data does not help at all.

That sounds promising, so I've edited my gps.conf to match and I'll get back and let you know how I get on with it.
Incidentally, I used Navigator today for the first time in ages and didn't expect it to work as I flashed a new ROM over the weekend, but it worked a treat. I'm in the UK but it was set to use a North American NTP server, so I'm surprised it worked!
Glad it did though
johncmolyneux, so that worked for you?
Can you please post in QUOTE your full gps.conf text?

This 10 sec. story was only once. Now I again can't accure sattelites. Will try to launch with gps.conf file fully empty. Will see, what it does.
Mine seems pretty stable now, but gps status seems to screw it up so for those still trying I'd advise you don't open gps status at all and/or force close it

I'll bear that in mind - thanks. I don't tend to use any extra apps anyway. We all know from WM days that the GPS in our phones is pretty good without it.
I'll try it tomorrow, when I drive a mile down the road to my local shop. And yes, I do know the way

Do you mean program GPS Status? Well, I'm using it to find a sattelites and then quickly switching to Google Maps. )))
Why do you think it can mess up the GPS reception? I'll try not to use that. Thank's.

When I open it to see what satellites are connected then go back to maps, maps is no longer as accurate even though gps status says it's locked.
It looks like it makes maps revert back to wifi or gsm triangulation.
Then if I go back to gps status, force close it then reopen it, gps status is no longer able to lock on nor Is maps.
So, I open maps, leave it for upto 20 seconds (usually under 10) it locks on to 2M accuracy
If I then open GPS Status, it says no satellites.
Exit back to maps and I'm no longer locked on and it doesn't seem to lock on again (cold start maybe.)
Then , force close gps status
Force close maps.
Reopen maps and I'm locked on again after a 'cold start' and then maps behaves itself again with under 5-10 second locks even after reboots and gps off/on

Oh, well, thank's. I experienced it today on a road, that after GPS Status, my Google Maps were jumping from GPS sattelites to Mobile Network Stations.

GPS Issues on Desire HD - Considerations, tools and tips

I'd like to make a unique single thread with all the issues related to gps on DHD and the procedures/tips to make it work better.
MY EXPERIENCE
I was ready to go to dinner to my girlfriend's uncle (50km far away). I bought my DHD two days before. Ok, let's try gps. Google navigator. Started driving and my phone didn't get a lock. After five minutes of driving, i needed some help from navigator. Nope, still no gps lock. I stopped the car, got out with DHD in hand and lock again in two minutes with the sky in sight. No problem until destination. At the end of the dinner, on the road again. For the first 3 minutes, gps lock. Then lock lost, gps icon blinking and nothing. Tried to reload the phone. Fast boot first time and complete reboot the second time. I didn't stop the car this time, tried while driving (my girlfriend handled telephone while i was driving ).
It took 45 minutes to get lock again. Thanks god, i learned the route on the journey there.
The same thing happened again three times in the next days.
I thought that some software installed corrupted my phone.....(sorry, i was used to the windows mobile whims!!!!).
Hard resetted, but the problem was always there. Without logic, sometimes i had gps lock, sometimes not. Sometimes my DHD was keeping the lock until destination, other times gps lock was lost while moving.
GENERAL CONSIDERATIONS
Not all the people complaints about gps on DHD. I don't know why but there are many people who have problems using it. I think that, except for the faulty devices with defective gps chip, the behaviour is the same for all devices. Only the people perception about the performances of gps are different, and their behaviours of use. I had different expectations about gps. I was used to start driving without gps lock, my HtcHD would have always found lock in one minute anyway. Even if moving, even if many clouds or raining.
People who arrived to Android coming from Windows Mobile do experience a general lack of speed in locking gps position and a very different way about gps is handled by the OS.
My DesireHD hardly locks gps where my previous HtcHD locked gps in few seconds.
The same difficulties I have now with DesireHD, I had them too when I installed Android on my HtcHD. But I thought it was the unstable Android SD ROM's fault.
Another issue is the speed of hot start: DHD seem to have a very very short term memory in fact of gps. Hot start is really hot only if you reconnect within short time.
My HtcHD was able to reconnect in few seconds even if hours passed from the previous lock, if not moved.
My new DHD needs more time to lock, even if the previous lock was 30 minutes before. It happens to take 45 seconds or more to lock again if the sky is not completely in sight.
Even if I get lock with GPS Status, shutdown the program and I reopen it few seconds after, gps lock is not immediate. It takes almost ten seconds to lock.
I think I have to forget the Winmo performances in fact of gps, on Android.
(I think it's the only thing i'm gonna be missing, anyway......)
I think i'll have to wait for the lock before start driving from now.
ISSUES EXPERIENCED BY USERS
- DHD locks gps but when moving it loses the lock and it stays for minutes (from 10 to 60) looking for it again. -
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock. Phone never ever locked gps, whether indoor or outdoor, with the whole sky in sight.
Try resetting AGPS data and let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
If you never ever succeed to get a lock, you should consider to have a faulty chip on your device. I think it's better to contact HTC Repair service.
- DHD behaves with no logic. Sometimes it finds a lock in seconds, sometimes it takes ages to find a lock.
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock if any data connection is available.
Try resetting AGPS data e let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
TIPS
Do all of these steps. And, except for the first, try to do them all the times you use gps. And evaluate the improvements, if there are.
One time procedure:
- Force the phone to lock gps without any data connection and check APN type (see below for the link to step-by-step procedure).
It is important to put the phone outdoor on a stable and straight surface in order to get a strong lock, with a complete view of the sky.
My advice is to empty a-gps data BEFORE doing this operation (this can be done with GPS Status - Menu => Tools => MAnage Agps state => Empty data - The program is free and doesn't need root permissions)
Before every use of gps:
- Use FasterFix (needs root permissions) to change NTP server zone. The system/etc/gps.conf file contains parameters for NTP server and AGPS data. In mine i find that the ntp server used is located in northamerica. I live in Rome so I use Fasterfix to change it, forcing to use european ntp server. I don't know why but Android changes by itself this file, putting again north america server, so i have to change it more than once in a day to keep it using european server.
NOTE: Fasterfix gives back an error the first time you open it, choose the seerver and try to apply it. Only the second or the third attempt, it returns an ok result. Don't mind error. Don't worry about it. Even if returned error, it did its job anyway.
- Synch Device clock with atomic time. I use ClockSynch (needs root permissions), but every program capable of doing the same thing can be used. This is intended to help device in calculating your position. More accurate time means less corrections by the software, faster position calculating and a more accurate position.
- Let the phone get a strong lock BEFORE starting to move with your car. A couple of minutes before, you should let your phone on a stable surface, with sky in sight. Outdoor, obviously. Better if outside the car.
This thing could seem stupid, i know. But let your DHD get the lock in a place where it has a good view to the satellites. Let it acquire precision (you can see it in the left middle part of the screen, using GPS Status). Start moving only when precision has reached a minimum value (expressed in meters/feets - lower value, more accurate). You will see that gps lock will be more and more stable than before.
- Use a task killer program to kill all the processes which may use gps. I noticed that if one or more program able to use gps have been left opened in background, sometimes, without logic, something goes wrong and Gps receiver is no longer reachable by software.
In this situation if I open GPS Status, I see gps icon blinking, but in fact no satellites are seen by the program. I mean that on the screen is not shown 0/3 or 0/5 satellites. On the screen i see nothing about the number of sats, neither 0/0, empty. And in some situations this thing cannot be true (i.e. if i am completely outdoor with a perfect sky view).

Good thread, helpful and insightful.
I am going to download all those applications as I too have been experiencing Slow GPS lock.
Just 1 possible solution for you, have you tried to upgrade your radio? This may sometimes help solve GPS problems.

No, I didn't upgrade my radio.
I'd like to do it but i'm very hesitant to mess around with my phone like this.
P.S. Let me know if you had some improvements.

Updated radio can make a MASSIVE difference. One of the best things you can do to your phone if you're having any kind of GPS / 3G / Wifi issues.
Go to:
Menu > Settings > About Phone > Software Info
Where it says Baseband Version, this is your radio version.
For me the most annoything that happens with GPS is that when playing a music and using at the same time an offline map gps program, when a voice or some ding dong sound happens, the music played stops and resumes after those gps sounds ends...
I think this is due to Android sys... even WinMobile it's better on this...
Thanks for the tips. My GPS is locking on very quickly now and even inside buildings. I used clocksync + GPS status + Fasterfix. Fixing to around 8 - 9 satellites indoors and 12/12 outdoors.
Done.
Great.
It Works!!!!
initially it would take me a good minute or two to acquire a precise location INDOORS, now it does it in 10-15 secs!!!!!!
i was already using GPS Status, this is with FasterFix.
Thanks.
so strange I never had problem with GPS, always fixes in less than 10 second and never loses as well.
I use iGO and it never let me down.
I had problem with gps-lock from the beginning.
Tried the link above "gps-lock without dataconnection"
Now it locks within seconds

Personally, I've had no problem with gps for apps such as Google navigation where the screen stays on.
It's a different story, however, for apps like cardio trainer where the phone loses gps lock when the screen is off. I understand this is a known issue with Android 2.2 and has been fixed for 2.3+. I don't know if anyone else has problems with this.

but mine desire didnt work? first when take out the sim card ,reset and download data ..it work like charm..lock around 10 sec..then put sim card back it took age cant find satelite to lock..
anyone know what wrong?
On my DHD, indoors, GPS sucks badly.. apps such as "aroundme" its pretty useless, just hangs finding a signal. but outdoors when I use navigation, etc it works okay. I dont use GPS that much anyway, so cant complain. It is a tad annoying when your indoors and cant find stuff though.
I've had really big problems with my GPS.
Could not get a lock so I rooted my phone and upgraded the radio. Changed the gps.conf file and reset A-GPS settings and tried GPS without a dataconnection. None of the suggested things above did work, so I downgraded the radio to stock and unrooted my phone and sent it to a repair center.
Hopefully they will fix it.
I have a Hero (root) and a Desire (stock) and they get a lock on within seconds and works flawless even indoors.
I guess HTC has a lot of faulty GPS modules in their Desire HD mobiles, but not all are using GPS so therefore we only hear about some of the problems.
Trying the Nexus one fix as in the first post, after taking SIM out, I do not get any GPS signals on GPS Status, if I put SIM back in I get fixes but GPS unusable as it keeps losing connection whilst in journey. The steps I have taken so far are as follows:
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status (ver 3.4)
* Go into its Settings menu
* Click on GPS and Sensors
* Click Manage A-GPS state
* Click Reset
* Click Manage A-GPS state again
* Click Download [You'll see a message telling you that a data connection is needed, ignore it]
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock, within GPS Status. This time, you’ll see your phone get the lock way faster than before.
Any help will be appreciated.

quoting my self...
There's some developments about this issue...
Or one use the nice HTC Gps Software (at least the version that cames with gingerbread) or use the iGO Amigo.
I tried the iGO Amigo and I finally can listen to music at same time when the voice from iGo speaks!!! There's no interruptions at all like on the majority of GPS softwares that I tried on my DHD (don't know how it works on another devices)
I think that this issue is something that is only developers fault cause initially I thought it was due android design, maybe it was only possible to play something only from one app at a time. (ie. not play two things from two different apps simultaneous) but I figure that after all that is possible.
Bad developers!!!!
GPS Problems: finally the solution
Hi all,
Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.
The way to solve exists ! Read to the end to know how.
I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.
It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.
The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.
Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).
I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.
No more fix and at maximum 2/3 satellites visible.
Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.
So I did a factory reset ... reset all settings as the original ... and retried. Nothing.
The GPS was dead for the second time in two weeks.
Then, I began a careful search on various forums (both Italian and international).
I've tried everything ... really everything ... but nothing. It does not work !
Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!
I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).
At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).
After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.
I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.
Now everything works wonderfully !!!
Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).
Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).
Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).
The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).
Believe me ... if you have tried everything ... this is the only way!
Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.
Im currently using Navigator, Google Maps, CoPilot and everything works great !
I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD.
Greetings to all.
Andrea.

[Q] GPS broken

Hi, the GPS in my 32A seems to be broken. I've tried several different roms, both new radio and old radio, and depending on the rom it either gets a fix once in a long while, or never. So I suspect a hardware issue. Could this be fixable in any way?
Unfortunately the fact that I had a working gps for several hours on Sunday proved to be some sort of a random fluke. Well, what I did was I reflashed radio, using a different minor version of 3.22, and that seems to have caused the gps receiver to work more or less correctly for a while. However, today it's back to its usual condition: able to tune in to 1 or 2 satellites at most, and of course no location fix. To make sure I kept it active for over an hour today (outdoors of course), running the gps-status app - its (non) performance was very consistent over this time span. At the end 50% of the battery charge was gone, too - but the display was on and at full brightness for most of that time.
UP I've seen other people have also experienced GPS issues esp. on 32 A and using Gingerbread ROMs. I'm interested in knowing whether this is a generic software issue with this combination, and if it would be a waste of time to try to solve it by downgrading.
Did you try to use the "right" GPS configuration.
I'm in EU - so i made sure that the GPS is using Europe settings.
Most roms use the US settings...
The last rom i used, took like 30 min to get a fix..
Changed the configuration file, i got a fix within 45 sec.

I get tired of explaining that this does not work. The gps.conf in this zip is exactly the same as the one that came with my current ROM. Its contents only affects how assisting data is fetched from the net. The GPS however should be able to work even in the absence of any data connection, you should just expect to wait a little longer for a fix. Data or not, I usually do not get a fix even in 30 minutes. In the rare cases when it works, location is soon lost or "sticks" at a previously reported position even when I have moved quite a bit since.
the gps conf is using normal servers or is it set for using google servers too? seems to be working better when using google server settings also on gb so i heard
The gps.conf is totally irrelevant here.
I have tried a total of five different GB ROMs, both on 3.22 and 6.35 radio. The GPS does not work correctly on any single one of them. I tried switching between different (but compatible) radio sub-versions underneath the same ROM. Nothing helps.
On Froyo (CM6) the GPS works somewhat better. Fixes are slow and precision is low; accesing the GPS sometimes causes a reboot; but at least this proves the hardware is working.
Interestingly, I checked that the libgps.so files found on Froyo and Gingerbread are bit for bit identical.
