copied and pasted from the gps faq:
hey guys,
im a long time reader and this is me first post here on the forums.
im having an issue with the gps for the xv6800 on verizon. ive read through lots and lots of posts regarding verizon and their gps service, agps and the like. my problem is that i dont ever get a lock, and never see any satalites in the htc gps tool. it just sits there.
ive got
VZW XV6800
Rom: DCD 3.2.0
Radio: 3.42.30
i installed the radio using the sprint official rom, and then put dcd's over that. im using olipro 2.40 and after i put in dcd's rom, i ran the verizon carrier cab. also the arc mms thing but im sure that has nothing to do with anything other than mms.
my gps settings are
com4
4800 baud
and manage automatically.
location mode is set to on.
i dont have tomtom or another commercial program to test, so ive been trying google maps and windows live. google maps tells me my handset doesnt seem to be compatible with my location, and windows live just tells me gps signal lost.
ive let it sit for roughly an hour and some change, trying for a lock, although that is unpractical for everyday use, i just wanted it to lock.
i read on here that other verizon customers gets theirs to lock in minutes, and that would be great for me if i could get that. so im asking, is it just my handset? or have i not done a crucial step in the flashing, programming?
didnt call verizon when i switched phones to reactivate data or whatever, i didnt know what i was supposed to ask them to do, so i just switched phones thru vzw.com and it makes calls and uses the ## codes perfectly. ive dont the *228 ect .
am i just sol? i really would love to have gps back, my previous phone broke, and i used vznav and that was great.
thanks in advance.
try this, and see if it makes a difference:

thank you for the reply but i forgot to mention that i have already applied the gps fix fromt the tutorial. i read somwhere that is persists through flashes, so i have not tried to reapply it after upgrading to the latest dcd.
if it truly does not then i will try to reapply that again when i get off of work
gmaps always says not compatible with my location (it is a feature some phones support that doesn't use gps) - don't use my location, check 'use gps'.... once the gps has a lock my location will send you to that location though....
I had the GPS working and then upgraded to the latest DCD.
I now have:
DCD 3.2.5
Radio 3.42.50
I have COM port set to 4, hardware port set to none and baud rate 4800 and let windows manage the gps. I also set it from 911 to location in phone settings.
None of my apps (GoogleMaps, TomTom) recognize it. And GPS Viewer bombs when I try to open COM4.
Any ideas? I really need my gps back.
I remember some people saying to briefly flip Location back and forth from 911 to Location On a few times, and having it work. Try that, and maybe grab the HTC GPS Tool to try and diagnose this.
Also, if you haven't already, you may want to do the GPS fix that involves messing with QPST.
Hmm, I've got 3.2.5 with the .50 radio, and using TomTom 7 fine...so don't downgrade, keep working at it, since I have that same setup and working fine.
You might try the radio rom again. I also hear that *22899 might help. There are some other GPS software out there that will show you the NMEA messages, see if you are getting any and if not then your GPS is not turning on or there isn't a GPS chip in that phone. Just kidding.
hi,
anyone able to get gps lock with telus TP stock rom ? just got my Telus TP and it unable to have it lock. it work fine with my mogul P4000...instant lock with TT 7.94... if anyone able to TT with TP stock rom or 3rd party rom...please give some details.
thanks
im using juggalo rom and i get locks with google maps within seconds.. never really tried to use telus stock rom as i unlocked and switched to a custom rom within an hour. i am sure that telus has it locked out so u can use their navigation software.
belmont, this is the link to the PPCGeeks thread of tobeychris' GPS solution and cab install for Telus.
have you set windows external gps to manage settings automatically?
tomtom gps settings config to built in gps?
"other NMEA" gps works for me as well...
also i've disabled assisted gps and it works fine.
i've ran juicy/or might roms (both built off telus roms) and my gps locks within seconds. should work right out of the box with stock rom though... seeing as how they do have telus navigator pre installed
Any ideas how to get GPS going? I've tried multiple roms, messing with QPST, following wiki, different cabs / reg settings, and I can't get anything.
There does seem to be some NMEA data flying around on COM4, but it is lines like $GPR,,,,,,,,,,,,,,,,,,,,,, , no GPS data in it.
I have tried many different programs, never getting even one satellite in view.
Currently system is:
ROM: dcd 3.3.4
Radio 3.37.75
PRL version 51574
PRI version 1.35_002
I have been searching google, here, ppc forums, and HOFO for DAYS trying to get this to work.
(also I am wanting to get QNC internet working, that is a secondary goal though)
If anyone can help me I would appreciate it.
Ok you are are with Verizon. And I bet you had MR1/2 before you went custom. The stock verizon rom blocks gps out with any custom rom afterwards. If you want a custom rom and gps then do the following roll back rom then go to custom again. http://forum.ppcgeeks.com/showthread.php?t=21161 Then apply gps settings. http://forum.xda-developers.com/showpost.php?p=3555579&postcount=703
The phone is activated on Page Plus, a MVNO that utilizes Verizon network. I got it from someone who used it on verizon.
When I first got it, I updated to latest "official" ROM, which I believe was MR2. I downloaded it from HTC's website.
I have just now tried to update my PRI using RadioRefurbish.exe but it does not seem to be working...
I will look at those things you posted. I had come across something mentioning that.. wasn't sure if it was what I needed to do or not.
**** Verizon. Ugh. Evil. Pure Evil.
Edit: I tried some Valhalla Legends, GPS Fix, blah blah other CAB files when I had MR2, with same results.
Ok, I have relocked device, and now I am loading the stock firmware.
What do I do after that? I can follow those steps. but... it does not seem complete information there on that link.
Do I install some version of valhalla, then do those steps?
Won't all that be lost on a hard reboot / ROM flash to custom ROM though?
Flashing to stock get you a 1.35 pri. You then can unlock, flash radio, and the go to which ever custom rom you like. The only thing is that i dont know if agps will work for you since you arent on verizon. But you so know agps requires a data package for use. You will have standalone gps without installing anyhting on the custom rom. I use standalone with no problems.
already have that pri as per my original post.
I was trying to get to the 2.x pri before.... do I not want that?
I also tried to flash a higher radio when I was on custom rom but it would not work.
So what do I do now, and in precisely what order?
.... right! Well, that makes it easy.
I unlocked again with 2.40, now I am trying to flash the latest version radio found on DCD's file server.
I flashed latest radio... unit hard reset, then afterwards I still have Radio 1.30.60 on device information screen.
If you could tell me step by step what I need to do, I would appreciate it.
Currently :
ROM version 2.09.605.8
rom date 05 03 07
radio 1.30.60
PRI version 1.35_002
GPS is now somewhat working, I haven't gotten a lock yet. Also haven't gone outside yet, might have something to do with it.
Now to get aGPS working.
Except DCD sucks, and QPST doesn't work in half his ROMs. Sigh. I'll have to find a decent ROM to use so I can get aGPS and QNC internet working.
Thanks for your help drewcam888, it set me on the right path to getting where I am now.
DCd is awesome and qpst works on all this roms. You must have a carrier cab installed to allow use of ## codes.
I believe you are mistaken. Why can I not connect then? I have installed Verizon Carrier cab. Com4 is showing up as "NO PHONE". Before it showed my phone.
I took my sister to breakfast this morning. On the way there, no GPS lock. Sigh. Sats in view, but only using one or two.
I shut down phone, then rebooted.
After eating inside, I fired up VisualGPSCE again. After only a few brief moments, locks on 7 satellites. Then it went back and forth between 6 and 10 locks.
Awesome!
So, either ephemeris was finally downloaded, or aGPS is working. Unsure which.
I loaded google maps, turned on satellite view, and the satellite imagery overlay correctly showed me on the south end of the restaurant. Cool stuff. GM claimed 30 meters accuracy, but it had to be much better. I would estimate 1-5.
I am wondering if this gpsOne chip is sensitive enough to use for geocaching. That would be cool.
Dude it isnt always on com 4. I have had it on com 10 and many others. Click add a port and find the diagnostic port. Don't blame others for your lack of knowledge. Your computer assigns this port and it can change.
The gps should be accurate to 1-2 meters I would think. But only is clear view of sky where you can find the most satellites.
There are no diagnostic ports to add.
Lack of knowledge my ass.
Google will reveal many others with the same issue.
Now unable to authentic my phone on Verizon.. just tried to make a call. Weird since apparently data and SMS both work.
Well I have gotten qpst to work on 3.2.5, 3.2.6, 3.3.4, and 4.1.2. So yes you are having a problem. It isn't with the rom. Are you sure you are dialing ##3424 send to enter diagnostics mode
Can you elaborate on how you have done this?
I go to add a port in QPST, but there are no ports to add in the left column.
Yes I am sure I am entering diagnostics mode.
I open QPST configuration. Then select "add new port". Then find which port my phone is on. Also are you using XP? I am guess you have the modem drivers installed being that you have used qpst before.
Yes, and yes.
There are no additional ports to add listed.
hmm. Maybe a computer problem. Do you see the phone listed under com ports under device manager. If not your computer isnt seeing your phone for some reason.
Under comp mgmnt there is HTC USB modem (with a yellow ! reinstalling drivers now)
Then there is a HTC diagnostic interface on COM4.
I can confirm that aGPS is working, since when I turn on GPS with GPS toggle, I instantly get a network logon request.
My akey has been deleted, that's why it doesn't automatically connect with EVDO.
See dont blame others. Ask questions and get answers before you accuse.
