I successfully rooted my friends Nook Color 8 gig tablet this evening and installed Cyanogen Mod 7 with no problems. I was looking at the storage space and noticed he was missing 2 gigs of space. It showed an sd card present even after I took the one I had installed, I thought it was weird, so I unmounted it, formatted it and when it rebooted it, it was stuck in ClockWorkMod. I was not able to restore/mount any file system of any kind. I did a backup previous to the install of Cyanogen also, that did not restore either. I now know I formatted the main partition(s). Is there any way to restore the Nook to factory condition and "re-root" and reinstall Cyanogenmod? One of the recovery methods I tried got rid of Clockworkmod and now when it boots it is just a silver "N". Any suggestions? I kept getting cannot "mount" & cannot "read" errors in Clockworkmod.
