GPS Detected but doesn't work - DCD 3.3.4

No the first RUU is the new "old" bootloader if i am not mistaken. You lock the phone and load the old boatloader, then the old ROM.

Okay, I have successfully re-locked my phone and restored to an old Verizon stock rom.

Radio 1.30.60
ROM 2.09.605.8
PRI 1.35_002

I don't have to do ANYTHING regarding the GPS before unlocking and flashing to DCD ROM & a new radio (and a newer radio)? I'd like to try all I can before getting into all these registry hacks for these aGPS hack.

Also, is aGPS only for people with a data plan? (I have NO data plan).

Thanks again!

Check the above link for registry and QPST settings for standalone GPS. I posted my near the bottom. Do not do any AGPS fixes you don't want AGPS without a data plan.

Thanks to drewcam, I've finally got this GPS working, with both Google Maps (when I can get a wi-fi connection), and TomTom Navigator.

I had to use the QPST software, under the gpsOne tab....

• Check and uncheck ALL boxes on the left column (including "Allowed"!)
• Re-check "Autonomous" and "GPS/AFLT Hybrid"
• Ensure that PDE Transport = "IP"
• Ensure that Position Calculation = "PDE"
• Write the changes to the phone
• Soft Reset

Does flashing a different rom overwrite the GPS setting changes I made in QPST, or is this done on a hardware level? (Do I have to make the changes each time I flash a different rom?)

It's not hardware level but it's more powerful than a hard reset or ROM flash provided you don't do stock ROMs. Every kitchen I cook in BuildOS automatically sticks the registry entries and my phone hasn't lost the QPST programming for AGPS.
