I downloaded the Rom Manager app, flashed clockwork recovery, did a nandroid backup of my current ROM (UD 8), wiped date, cache, and system, but am now stuck at the M boot screen. Before wiping everything, I downloaded the most recent stable version of CynagoenMod from within the Rom Manager app, but am unable to find it in recovery now. When I try to use the nandroid backup, I get "MD5 mismatch" and it fails to restore. I actually made two separate nandroid backups tonight within clockwork and both get the same MD5 mismatch error message. Any help would be greatly appreciated.
