i have a question...i want to root my phone and install the new villain 5.3 rom so that i can have droid 2.1 but my question is, what happens if it craps out on me and i need to revert it back to the way i got the phone from sprint...where can i find instructions on how to do that and where can i find that software?? sorry if this is a repeat question but i searched a bit and didnt find it.
