Roll-back from Verizon Official WM 6.1 ROM & GPS

[tgerbert]

I foolishly upgraded to the recently released WM 6.1 ROM from Verizon, apparently Verizon's locked down the GPS so you can only use VZNavigator. There's a work-around, but I still like my custom ROM better anyway.

So, my question is, once I ran the Verizon ROM did it update the firmware for the GPS chipset and this that what locks down the GPS, or do they do that in windows? Can I go back to a custom ROM and have a working GPS, or do I need to (and can I) re-flash with another carrier's ROM first to roll-back firmware in GPS?

What? Every user with the VZW ROM has GPS, including myself. Where did you get the ROM from?

GPS never worked on my XV6900 with the VZW ROM...

See this thread here for info on making the GPS work http://forum.xda-developers.com/showthread.php?t=424387, and an article here http://www.phonenews.com/verizons-htc-xv6900-update-packs-punch-were-offering-it-early-5417/ dated 11/11/08 - maybe I'm missing something though (maybe I'm in the wrong forum? ;) )

I've since tried using an older alltel ROM, then going back to my cooked ROM with no luck. I seem to recall reading somewhere though that it wasn't necessarily a good idea to roll back firmware, so I re-ran the VZW rom, skipped customizations, then put a cooked ROM back on, tried this fix http://wiki.xda-developers.com/index.php?pagename=VerizonAGPSFix, which worked previously, but still no luck.
