I recently rooted my phone which was on 2.2 at time of rooting using unrevoked3. Everything was going well, I performed a full Nandroid backup, moved su to \system\xbin as suggested in many posts. Today I did a phone shutdown, then pressed power + volume down to get into the ClockworkMod Recovery v18.104.22.168 menu with the intention of doing another Nandroid backup. I selected 'backup and restore' from the recovery menu and then pressed the power button to select. But pressing the power button only blacks out the screen instead of selecting the menu option. I tried depressing the power button for a longer period of time...same result. Essentially, I'm unable to get out of the Clockwork menu. Hope I haven't bricked my phone. Any ideas?
