I want to be able to root my droid using one-click methods again. so, I was wondering if there is a way to go back from the Droid 2.2 FRG22D build to FRG01B. I have both update files saved on my PC. So, Can I use the FRG01B update.zip to change my current build (FRG22D) to the FRG01B build without bricking the droid? thanks.
