I have a droid 2 version 2.2 and my phone has been rooted with z4root until last week when I accidentally downloaded android 2.3.3 now my phone is not rooted anymore and I have tried gingerbreaking and it would not work, can anyone help
If your phone was rooted before GB, you will most likely have to revert to a clean froyo, then upgrade to GB, then follow this root guide Just backup all your stuff before wiping it.
