If you arent rooted you may as well hang up trying to downgrade from the leaked version of 2.2. iT wont let you do it period. Thats why I waited and flashed the rooted version instead. If you try to go back its gonna give u that error about updating an earlier version and fail. All youll be able to do now is wait on htc. This is why I make sure I maintain my root EVERYTIME an update comes out.
