I was running CM7, the latest nightly (139) pretty nicely on my D2 and got bored, so I went to ROM manager, downloaded Liquid Gingerbread 3.2, and went to install it. The backup of CM7 went fine. Installation appeared to go ok, but on the reboot, my phone got stuck on the Motorola logo for hours. I figured something had gone wrong, no biggie - but when I went to Clockworkmod to restore my backup, I see a message saying my backups aren't available. Uh oh. I then downloaded CM7, renamed it update.zip, but trying to install that fails due to a signature error. There's no option to do a factory reset. I don't have a clue on what to do after this. Anyone out there have any ideas? I'm sure this has been seen before.
