Flashing A ROM or Recovering w/ Nandroid
So... Brand new to Nandroid backups, flashing ROMS, etc. I wanted to flash AOKP, so I went through everything Google said I should, made a titanium backup, a nandroid, then went into recovery. Factory reset. Now, I can't seem to flash AOKP, and I'm completely confused as to how to actually use my titanium nandroid, and santa backups. Any help is appreciated.
