Last night I rooted my Droid 2 and everything went fine. Then I started searching for ROMS to install on my phone. I found one and before I installed it, I made a complete nandroid backup using the clockwork Recovery Mod v22.214.171.124. After that I tried installing the Fission 2.5.7 ROM and everything seemed to go okay, but when I tried to boot up it just stayed at the bootloader for hours. When I tried to restore the backup I made it only said "MD5 mismatch", thus the situation I'm in now. Any suggestion on what I should do?
