be careful here. downgrading the actual RADIO can be bad. there is certain 'stuff' within the newly enabled GPS chipset, (when you originally flashed to 3.27), that can't be turned back off when downgrading back to the stock radio..

all you really have to do is just re-flash the DCD rom..

so when i read your comment about reverting back to the orig. verizon rom, i am crossing my fingers that you didn't go back to the 2.xx radio....

that XDA thread is certainly long winded, and seems like they are making a novel out of a short story. all you needed to do is a hard reset, then re-flash the DCD 3.x rom...
whenever you then see it reboot and go to the startup screen - just make sure you soft reset when it says 'Customzations will start in 3 seconds, tap screen to begin'.. (or something like that).
going forward, ANYtime you flash a new rom, you MUST NOT let the customizations run..

are you getting the bug yet ?
