A little over a year ago I got GPS working. I'm not sure what I did that finally worked. I did everything from registry edits to driver installs to swapping WM libraries. I also believe I have been using one of OMJ's ROMs this whole time. I can't remember. I've been using TomTom 6 with fair success.

This week I finally decided to update my year+ old ROM. Now I can't seem to get GPS working again.


Here's what I've done:

First, I installed the official Verizon update, letting customizations run with the Valhalla Legends GPSServer:
RUU_Vogue_VZW_WWE_3.14.605.1_Radio_3.37.78_Ship.exe

I later discovered that the official 3.37.78 radio release changes the lockdown on GPS so it no longer works. So I followed the steps here:

After installing the Verizon leaked 3.37.77 release (no customization), I installed the Bell update (for the radio, no customization):
RUU_Vogue_BM_WWE_3.09.666.1_Radio3.42.50_Ship.exe
Then, I tried:
NFSFAN's VERIZON 1.12 ROM.rar

I followed the top part of the guide here:
http://wiki.xda-developers.com/index...VerizonAGPSFix
My phone was automatically signing into data and it didn't work anyway. So, I tried using QPST with the following settings instead:
PDE Transport: DBM
Position Calculation: PDE

I also tried Position Calculation "Mobile".

I tried changing the GPSMode registry to "1" (MS Based?)

I tried Valhalla again, even though that shouldn't work; it didn't.

I repeated the steps here:
http://wiki.ppchaven.com/index.php?t...IX_VERIZON_GPS

This time I stayed with the Verizon 3.37.77 release without customizations. I expected the non-Valhalla method to work. I tried all the same methods mentioned above (QPST/Registry/Valhalla) but none of them work.

I'm considering reinstalling the leaked Verizon 3.37.77 radio release WITH customizations in combination with the Valhalla method. Won't this screw up installing 3rd party ROMs?

After a thousand soft resets, I've been using TomTom and HTC GPS Tool to verify connectivity. TomTom says "No GPS Device" and HTC GPS Tool says "Fix not available".


At this point, I'm so f'n annoyed that I've wasted so much personal time on this. I swear when my contract is up I'm switching to a GSM network. I love Verizon's coverage but I'm sick of these games where Verizon (and Sprint) try to force users to pay for services they don't want or need by crippling the phones.

I feel your pain. From what I have read, if you let customizations run then you are basically screwed. My phone came with WM6 loaded. I unlocked it with 2.31 & then flashed the leaked Verizon Rom & radio. I never let customizations run with the original ROM or the leaked one. The GPS did work I was able to get a fix using the HTC GPS Viewer. It took quite a while to get a fix though. I tried the AGPS fix & encountered the same problem as you.

At this point I decided to flash the official rom. I did the registry edit.

Registry Edit:
HLKM/Software/HTC/SUPL AGPS:
Registry Key name value
EnableAGPS: 1
EnableGPSSmartMode: 1
GPSMode: 4

After this I was getting locks a lot faster but still having issues with TomTom. The I found this thread over at XDA-Developers.

Even after this the GPS would not work after my phone went to suspend mode. I lived with it for a few days & decided to flash a custom ROM. I flashed NFSFAN's Verizon ROM & let the customizations run. Now the GPS work flawlessly. People seem to have mixed success & I cannot explain it. I never let customizations run until I flashed NFSFAN's Verizon ROM
