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 I'm new and i have found that on this stock firmware (Sprint), i can fully use the GPS without having data (which i don't). I used BAF GPS toggle for the today screen. Here is what i did:
installed TomTom GPS software
installed BAF GPS toggle
when you turn the GPS on, it will automatically try and start the data
connection, make sure it doesn't connect if you do not have data. even if you
do, its not going to do anything for you.
link: http://forum.ppcgeeks.com/showthread.php?t=21278
started TomTom with default GPS settings
and i waited a bit to get a lock and KABOOM it worked.
I did this on my Mogul with the current firmware from sprint as i said at the top. This has worked for me every time i have tried.
Did your Mogul come with 3.35 ROM and 3.35 radio?? If it did, then yes you have the drivers in the OS to enable GPS....
yes i have the 3.35 radio and rom. but without the BAF i couldnt find how to enable the gps without starting vision services. this also works on the current dcd build.
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:
http://wiki.xda-developers.com/index.php?pagename=TitanGpsFix
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....
Hey all. Here's my config:
DCD 3.2.6
Radio 3.42.50
PRL 51056
PRI 1.35_002
I've also applied all of the QPST changes per gc14 with the PDE IPs, settings, etc. I've also verified that my default reg values are correct.
So I can now lock GPS outside within 2 minutes or so after applying all the patches. I do use GPS Viewer to prime, but am seeing a strange thing in all GPS progs now. GPS Viewer as well as iGO8 will flash 10 gps signals for 1 second every 5 seconds, then the signals will disappear, repeating this forever. I assume these are aGPS signals but i'm never getting a "lock" inside, only outside, even though my cell signal is fine inside. Anyone seen this problem, or have any idea what i should check next?
Thanks,

Does the "GPS" section of FieldTest.exe show pilot phase/strength/time offsets? These refer to pilot PN offsets (i.e. tower sectors), as far as my understanding goes. If you are using standalone GPS, my suspicion is that you won't see any data here, however, not having the capability to do standalone GPS on my device just yet, I can't be entirely certain.
Worth a look, though.
Me too

Yup, I have noticed this as well. Happens to me regardless of Radio, PRI, or ROM. I see it a lot with HTC GPS tool. Dont know what it means but I eventually get a lock. I think VZW still sucks and the PDE servers are not as good as Sprint maybe? Im not seeing the "5 seconds locks" everyone else is. I am however getting very fast locks, maybe 20 to 30 seconds. Nothing more than that though. On occasion I still fail to lock but far far less than I used to without the PDE infomration. I dont know what it is but I can confirm what you are seeing.
Radio .40
DCD 3.2.6

My Fieldtest doesn't have a GPS Group, so no info there. Any other ideas?
Sorry, it's FieldTrial.exe and not FieldTest.exe.
At least with the MR1 ROM, there's a Debug Info menu where you can select GPS to dump GPS debugging information.
When using AGPS on my device with VZ Navigator, this is updated with tower information. I don't have a device that uses standalone GPS, nor a device with a different ROM other than the MR1 ROM, so I can't really speak for that unfortunately.
I'm not completely certain that you won't see the PN-related fields filled in using standalone GPS mode. However, from my work at hacking on the V740 some time ago, I suspect that pilot phase values are going to be related to cell triangulation (time offset of the signal from the cell towers being used for triangulation against the current CDMA time when the signal was received by your device, i.e. propagation delay).

Hmm, maybe we are getting somewhere, but I dunno since I have never used FieldTrial.exe before. I just fired it up and the entire GPS tab shows N/A for EVERY field. Does anyone else see that with a working GPS?

Okay, I think that you're operating in standalone GPS mode.
Rationale:
With my device (on MR1), when I access the GPS through the custom interface that LBSDriver.dll uses (i.e. via VZ Navigator), I'll start to get data in FieldTrial.exe (on a fresh boot, all the fields are N/A). Of course, the latitude/longitude are garbage (having not been through the decryption logic) as shown in FieldTrial.exe for me, but the rest of the fields (e.g. altitude and GPS time, as well as cell tower triangulation data) show valid data.
To me, this indicates that FieldTrial.exe is just pulling AGPS-related data and not standalone data.
Can you try disabling the phone radio entirely (via Connection Manager or whatever the app is in your firmware) and see if that changes the lock speed at all? If not, that's further credence that you're not using assisted GPS. (Caveat emptor: I don't know if disabling the radio will also turn off standalone GPS, as I don't have any way to check that. It should be pretty immediately obvious to you if it does, though.)
I tried the methods described in the forums to unlock the gps on my vx6800 , but i have no luck at all. Still not finding satellites in google maps and live. Rom 3.57.605 radio3.37.75 rpi 2.03_002 . Does anyone know how to solve this issue?Also how to remove vahalla gps manually from my device? I hope someone can help. Thanks in advance.

I'm no expert by any means but I have my Titan (xv6800 for Verizon) unlocked and GPS working fine. The difference I see from yours is your radio. I have radio 3.42.50. If I am not mistaken this is the current recommended radio for GPS capability. You also should install the GC Verizon aGPS cab to prime the GPS. The cab just uses your internet connection to find the current locations of the satellites which provides a 5-15 second lock in most cases. Ill attach the cab so you can install it. Also make sure that Google maps is manually set to use "com 4" and a baud rate of "4800". As far as the "Live" and "Valhalla" problem, I'm not sure because I haven't used either one. Also before you install that radio, make sure your rom is compatible with that radio. Again I am in no means an expert, just a student learning from these forums. Hope this helps.
PRBajista 9:
Do not install the above cab. Look here in the last ten pages for the new cab since verizon is messing with the gps settings. It is in serfboreds signature.
http://forum.xda-developers.com/showthread.php?t=424387
Also try to use htc gps tool or gps viewer to verify that the gps is seeing satellites.
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.
