I would get a program that shows the NMEA messages like GeoScout and see if you are even getting anything. Could be your GPS chip is hosed. Good luck sending that back in if it didn't come with it turned on like from Verizon. If you are in a clear space and you have reset the phone and you get no NMEA messages then I would think that either you have a bad flash and to start over or your GPS chip is bad.
Mine was acting similar which was every frustrating. SO tonight I flashed the new radio 3.42.50 and it did not help. I then reflashed DCD 3.2.5 and my GPS magically started to work again. I now lock 4 satellites from inside my house in about 15 seconds. The only bad thing is it shows my location in Gmap and Live about 10 blocks off. If I do a soft reset it has the correct location. If I exit maps and relaunch it is off 10 blocks or so again. No big deal really, I'm just happy it's working again.

Hey all,
I have my athena for a couple of days now but I still can't get the GPS to position. As it is a T-mobile Ameo I used Oprio's Unlocker first. Everything went fine and now I can use it with every SIM. Then I upgraded with the WM6 Dopod U1000 and so far so good. The only thing that worries me is that I can't get the GPS to work. I tried both OziExplorer and Googlemaps, also BeelineGPS and GPSTuner. None of these programs can find a satellite and obtain a position. Am I missing some settings or maybe there are no satelites over my area?
OPp and something else that bothers me. Is the Status Display just not working under WM6 or it's only by me so?
I have the x7500/Advantage and GPS works after updating to WM6. I haven't yet unlocked my phone because i'm waiting for the cooked ROM's to be released before I go through this.
Have you installed maybe some other software that uses GPS and see what happens or are you trying it with just one program?
have you changed the gps settings in start-settings-system-external gps?
I use software-none hardware-5 baud-9600 tick-manage auto.
run quickgps first before you try any of your programmes,and let it update, this will give your progs satellites to look for and speed things up a bit, it does take some time to get a fix.
you haven't tried selecting it as a sirf-star have you? that will stop it working and need the battery leaving out for a while..

yep I tried both COM5 and COM4 with 4800/9600, also ran the QuickGPS.
What do you mean by selecting it as a sirf-star?
some software (for example memory map navigator) gives you the option to select different types of gps receiver protocols, there are a few. garmin, navman, magelan, sirf, nmea,
nmea is what the 7500 uses, but if you select sirf-star then it appears the gps shuts down, and the best way of restoring it at present is to either take the battery out or if you're lucky just hard reset it.
I did this
No, I haven't selected sirf. Is there some simple GPS software just to try whether the integrated GPS is working? Could it be just that there are no satellites over my area?
Come on guys, tell me how you get your GPS to work. Should I go back to WM5 or maybe change the Radio ROM? All the programs I tried still can't find any satellites? Any suggestions for other settings?

I don't have an answer for you, but I can tell you that the GPS satellite system covers the whole planet, so there are some over your area. Sounds like it could be a hardware problem.
Hmm I know but althoufh I am in the city centre it shout find at least 1-2 satellites. Maybe I should go somewhere out of the city and try there. I still doubt that there's something wrong with the settings or the software.
i had the same problem, using AMEO, unlocked using olipro unlocker.. GPS never worked afterwords .. the SIRFbootloader section in the ROM isn't updatable getting a communication error and that is it. I've to return it to T-mobile.. don't know how to remove the Olipro bootloader and how i can get back the original T-mobile rom!
Hope your problem is fixable .. as mine isn't

I did upgrade to Olipro, but I have bever seen any communcation errors. As far as I can tell, every upgrade went fine. My GPS works in 2% of the cases, it takes forever to get a fix, and after even the slightest displacement or move, the fix is gone again.
I am not getting any communications errors. I did all all the settungs as shown on this site http://www.x7501.com/forum/YaBB.pl?num=1184315093/0
and f.e on Google maps it just shows "Seeking GOS satellites (0)"
On the BeelineGPS I get "Fix not available" and a red circle blinks.
I really don't know what to try more. Maybe should I flash another Radio ROM or get back to WM 5.0? Any other suggestions?
mine too after upgrading to WM6, my quickGPS is not able to download the satellite data via Activesync. i used to be able to do so on WM5... whats wrong?
try this!!
Unplug battery then plug it again, this will help your mobile like factory reset !

For tests I am using old small app which was fro PPC2003. It works fine with my Advantage X7500 on Com4 and 4800 baud rate in WM6. It usualy starts showing satelites after 1 minute or so.
I have attached it here.
Edit:
I never tried to use quickGPS via ActiveSync. I use vsta. However it works fine and downloads GPS inf via WLAN/GPRS/UMTS or what is actualy available.
Did you do step 2 and three of Olipro Unlock
Step 2 Sends A Radio Rom to Unlock and step 3 a Rom tha make your GPS work again
It says so in the Olipro Unlock Documentation
Hey all. I have DCDs 3.2.6 ROM, 3.42.50 radio, and iGO8 navigation software installed on my Verizon XV6800. I can receive and lock GPS in about 5-7 minutes using the Holux GPS Viewer v1.5, however if I lock GPS and navigate using the iGO8 software, if the unit ever loses GPS lock the entire phone freezes up. This happens every time i'm using iGO8 and I go inside, block the GPS signal for a second, etc. Very frustrating to have to pop out the battery every time i'm using iGO8, any ideas what I should look for to troubleshoot?
Thanks.
not sure if astro launcher is compatable with that app but it works great with tom tom and it restablishes a signal when i power down and then back up

How are able to run iGo8 on a 6800? I dont believe there was enough RAM to get it to run smoothly, and it would lock up all the time. Just what I heard over at Ppcgeeks.
Steve
I have the exact same setup and i run iGO8 just fine. Depending on my build or rom that I use, it will load up immediately after install, but since ive been using 207XXX builds, I have to reboot after install. I used to us Astrolauncher, but i have fallen in love with GPS toggle ... especially the latest version that shows the sats on the screen. Sweet!
I run OnCourse8 which is really like iGo8 and it works flawlessly. Either use Baf's GPS Toggle or Astrolauncher to prime for fast locks on a xv6800. I'm also running radio 3.39.10 which seems to work alot better for GPS in my area.
Please post all discussion/issues/comments regarding Bell Mobility GPS/aGPS in this thread.
aGPS locking up
I'm running Bell, dcd 3.2.5, radio 3.42.50 with aGPS working just fine, for a while. After a couple of times of turning the screen off (Power button), or standby, or whatever you call that mode...TomTom 7.450 (and GPStoday and Intelligolf all latest versions) stop locking via aGPS. Normally I get locks in 5-10 seconds with all these programs but afterwards I get nothing. TomTom shows satellites but won't lock on to any of them.
Please ask me questions if I missed anything. Any ideas?
I used to have the same issue. I upgraded to dcd 3.2.6. Still with radio 3.42.50. I also did the aGPS setting enable per another thread. Since then, I no longer have that problem. I get quick satellite fixes for days on end without the need to soft reset.
Power mangement
Hi all,
easy fix, I had the same issue. It is the power management. Once you put your phone to stand by the GPS will not come back up unless you use Quick GPS (don't know why but it bring is out of standby) or you can do the following regedit.
In the regestry I found these settings for power management.
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Interfaces]
"{EB91C7C9-8BF6-4a2d-9AB8-69724EED97D1}"="Power-manageable display"
"{98C5250D-C29A-4985-AE5F-AFE5367E5006}"="Power-manageable NDIS miniports"
"{8DD679CE-8AB4-43c8-A14A-EA4963FAA715}"="Power-manageable block devices"
"{A32942B7-920C-486b-B0E6-92A702A99B35}"="Generic power-manageable devices"
Each one of the {} strings are an IClass for other device including the GPS. The one found in the GPS was this "{A32942B7-920C-486b-B0E6-92A702A99B35}. When I deleted the IClass string out of the following keys, you are now able to put your phone to standby and the GPS will keep running.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID]
"IClass"="{A32942B7-920C-486b-B0E6-92A702A99B35}"
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\SerialGPS]
"IClass"="{A32942B7-920C-486b-B0E6-92A702A99B35}"
Thanks for the info guys! I'll try deleting the registry items first and see what happens.
AGPS and Data usage
Hi, I am hoping someone can answer this for me, does AGPS use data, is it costing me money to use it? I have read many posts and still I am confused. I am using dcd rom 3.2.6, radio 3.42.50 PRI 2.02_007. Thanks
I noticed a significant decrease in lock times after going to PRI 2.02_007, FWIW.

Yes, by default the assisted mode will request to transfer small amounts of data (download satellite ephemeris data) over the network everytime the GPS is initiated and when satellite coverage is obscurred (location determination from a IP defined assistance server).
I have confirmed this with my online data summary with Telus.
Thanks for the for the help.

What kind of lock times are you seeing? I'm seeing 10-15 seconds. I'm fine with that.

About 10 seconds. It was way longer before. Sometimes a few mintues.
I'm running DCD 3.2.6 with radio 3.42.50 and PRI 1.34_007. I have ridiculous lock times most of the time. I don't use QuickGPS or anything else other than Google Maps. I've waited minutes sometimes to get a lock. I live in Milton, ON, and use GPS typcially anywhere in that area and the GTA (Toronto) area. I don't use GPS all that often and perhaps that's why is slow to lock each time I try and use it?
Regarding the PRI comment made earlier in this thread. I'm curious how you upgrade your PRI? I've tried the "Update PRI" icon in Settings | Connections, and although it reboots after doing something it's always the same rev afterwards. It also returns an error after it tries to update and prior to the reboot -"backup EFS failed" in a window with a window title of "PPST". Tap okay to that window and the phone soft reboots and nothing has changed.
I also could not update PRI using the icon provided by DCD. He provided the attached cab version in another post. You will have to install it on your device, then run /windows/ppst.exe
Also, be sure to do the GPS fix found at this link:
http://wiki.xda-developers.com/index.php?pagename=TitanGpsFix
These 2 things should fix your lock times.

I think I am having the same problem as everyone else with the Alltel TP GPS. I have absolutely no luck finding satellites in my hometown, yet if I travel out of my hometown I can get signal 99% of the time. I tried locking in while I was driving back from work (Ocala, FL) to my hometown (Sarasota, FL) and it worked all the way to my house. As soon as I turned I turned Google Maps off it couldn't find me anymore.
I have tried all the tricks to make it work including the obvious "turn on my location".
If anyone have a solution that works please let me know. I have heard that if you use the Alltel Nav program then the GPS picks up very well, so there must be something there.
can anyone help?
if you are running stock rom its a little finniky at GPS but if your running a custom rom then its a lot better... also the stock radio seems to be little strange...
if your not running stock what are you running?
do you have quick gps installed?
I am using the stock rom. I am not familiar with other ROMs, I haven't looked into that aspect of it yet. What is the best ROM for an Alltel phone (IYO)? Do the other roms still use TouchFLO? Am a very graphic person, so I like the prettyness of TF3D.
i had problems getting a satellite lock in my home town when i had my 6800 with my tp its much better i am running energy rom found here over at ppcgeeks http://forum.ppcgeeks.com/showthread.php?t=69545. i really think it just has to do with the area/amount of towers. there has been some discussion about needing gps services turned on on alltels side. Saying that if you sign up for there navigation service they will open up gps and then cancel service(i have never used their service and get gps). It sometimes would take awhile for me to get a lock and then only pick up one or two satelites then out of area i would pick up a bunch. have u tried htc gps tool? also check out visual gpsce. try all different radios too. im curently running the vzw rapael radio found here http://forum.ppcgeeks.com/showthread.php?t=46616. once you flash over your alltel radio u will not be able to flash it back stock since the alltel radio has not been dumped yet (something i was not aware of when i flashed). im going to bet though if you unlock your phone and flash a custom rom your gps lock will be better. good luck!
I installed ConFlippers Rom for the Alltel TPs and I like it a lot, but it didn't do anything to help my GPS lock.
Changing doesn't always helps. Conflippers is a great rom because its exclusive for alltel and is very easy to flash because everything works. With conflippers you need to install "htc gps tool". Then once you have it do the following: select "clear memory" ->open for 15 sec.->close->select "cold or warm start" ->open 10 sec.->check nav init.->check your satellites. If you got green then go to google maps or whatever program you are trying to use gps for.
If you would like to try a different rom then sometimes simply cycling the location setting from on to off then back on again or soft reset is in order. Keep your quick gps up to date.
There is not one fix for all gps problems for the t-Pro. You will find a routine that works and it will no longer be a problem. One thing that works 100 percent of the time is with the stock rom, paying for alltel nav will give you locks instantly in any program at anytime.
I'm using Nfsfan's CDMA Touch Pro Rom
I install the Alltel Carrier Cab and MMS cab in my faq
when I flash it to make it work 100% with Alltel.
(mms=Picture/vid messaging)
The link to my faq is in my signature.
Also, in post one of my signature there is a link to a post I've made
describing what's vga compatible and what's not
till I finish getting everything for my TouchPro Faq.

Well, I've had my Alltel Touch Pro for about 6 hours now, so I'm hardly an expert (coming from my eternally flashed and reflashed PPC-6800) but, here's my experience with GPS:
Bought the Touch Pro from the Alltel corporate owned store. Walked outside to my car and got in. Went into the phone settings and turned Location On. Popped my Garmin Mobile XT (bought retail, not cracked) card out of my 6800 and into my Touch Pro. Let it install. Started up Garmin Mobile XT, got on the highway, and within a minute had a nice GPS lock.
Obviously, all on the stock Alltel ROM (no time to look into custom ROMs yet, I've only had it for a few hours!) So I can state that at least in my case the GPS worked fine out of the box without any sort of priming or tweaking. YMMV.
Yea, like I said mine works great everywhere I have been except for my hometown. I can even hook up to my bluetooth GPS receiver and it works great everywhere. Just can't seem to get a connection in (Sarasota, FL).
Hi, I bought a Motorola Atrix in Amazon 2 months ago. Since start the Gps din't work at all, 0 in view in apps like "Gps test". I tried almost everything: changing gps.conf, flashing radios, using custom roms like Nottachtrix and CM7, and reverting back to stock via rsd. Btw, a friend of mine who bought the same phone at the same time, had problems with gps in stock rom, but after flashing CM7, it worked just fine.
So, I ask you to help me giving any ideas to fix this.
Maybe this can be useful: The Atrix came with Italian retail rom and N_01.100.00R radio.
Thanks a lot.

If you use an app such as GPS status do you pick up any satellites? It seems to be a common problem to find the satellites but not to be able to get a lock.
Also is you install GPS Status it will allow you to update the agps files.
Did you try gps lock with data access enabled? And as eddhard said do you pick any satellites?
In the gps settings menu turn OFF the options to use mobile networks or wifi. Then use the gps status or gps test app outside in a clear view for a minute or two. If it reports an accuracy distance as 0 or an error there is an issue with your gps that I might have a solution for.
For no reason my gps straight up failed to get a lock. In the test apps, it would see 9-10 satellites with strong signal but never wanted to get a lock. Multiple multiple factory resets, formats, any other variable I tried to change and the issue persisted.
I've attached the file that fixed the issue for me. Extract the libnmea.so and place it in your /system/lib folder after you make a backup of the existing file. Let us know if that helps.

Thanks for your answers, the problem isn't the locking of any of the sats. Test apps show "0 in view" even on outdoors.
I don't have a solution. But I've had a lot of difficulty with GPS on my Atrix as well. I can get a lock usually after a minute or so, but then the GPS would go to sleep. So if I'm moving or logging a route, it'll show me where I started even after several minutes. I flashed radios, updated gps conf, and used GPS Status & Toolbox to get a lock. Still no improvement. It helped me get the initial lock, and didn't resolve the freezing issue. I eventually gave up and bought separate GPS. So I'd be interested to know if you find a way to fix this.
Guys, if you don't see any satellites in GPS Status app, maybe is hardware issue. If you have warranty, use it. If you don't, try to disassemble your phone and look. Maybe just cable is disconnected or has bad contact. Of course be very careful with disassembling or ask someone with experiences. Youtube guide how to change digitizer on Atrix could be useful.
Good luck
I had problems with GPS fix on AT&T atrix 4g with N_01.100.00R europe radio. After flashing 37p at&t radio gps works perfectly, fix is really fast.
Also WiFi signal strength increased.
