Okay, been digging through search and the wikis and cannot find the answer.
We have a Pre 2 Unlocked GSM that was converted to a Sprint FrankenPre using an original Sprint Pre comm board.
Now, we're switching it from a Sprint account to a T-Mobile account. Unfortunately, it is of course, still a FrankenPre and we'd like it to be a GSM Pre 2 again.
I can't seem to find steps for this. Somehow my instinct says to swap the comm board back, and then run a regular Doctor on it... However, I don't want to BRICK it (she'll kill me), and so I'm not sure if any other steps are required to restore it to original unlocked GSM condition.
