I am another person that can attest to the need to DOWNGRADE before doing anything else.

I received a replacement phone with MR2 already on it. I decided to just unlock it, with olipro 2.40, leave the existing 3.37 radio, and DCD 3.2.6. Everything took fine and I was able to activate it with no problem. I then tried to do the aGPS fix wiki which completely killed my ability to make/receive phone calls BEYOND repair.

Manual provisioning, an hour on the phone with Verizon, no luck. Had to swap the phone out.

This time, did the same procedure with the new device, but DOWNGRADED first. No problems.
