Ok so I rooted my mother's Droid 1 a while back, and now, after the 2.2.1 update, it is unrooted (no root apps will work), but it still has the superuser app on it. I downloaded and installed z4root and tried to root it. It wouldn't work. I read the bottom of the app and it said that the su binary is on the phone, so I tried to unroot the phone. Didn't work. So now, I'm thinking I need to SBF, but I can't find an SBF for 2.2.1. So, is this what I should be doing? And if so, is there an SBF for 2.2.1 on the Droid 1 yet? Thanks!!!
