ok here's my situation. I was running nookiefroyo and everthing was working fine but I wanted to upgrade to cm7 rc4. So last night I prepared my sd card with cwm and put the zip for cm7 on the card. I formatted the data, cache and system but then when I went to install the zip it says "installation aborted". So then I tried to restore my nandroid backup. It went through all the restore, took about fifteen minutes, but when I restarted it got stuck on the screen with the android text in the upper left of the screen. I've done all the steps about three times. I even tried a different rom, nookiecomb, but still got the "installation aborted" error. What can I do to get it working again? Thanks for any help.
