So I used rsd 4.6 to revert back to 2.0.1, then I started to make a nandroid back up but never finished, because i heard it was unnessecary since rom manager could back up and all that jazz for me. installed rom manager and tried installing different roms. but whenever i reboot i get stuck on the M screen. same with downloading, or installing from sd. So then I just hit yes to updating back to 2.1 and i had the same problem. can I rsd from 2.0.1, should i? what and i dunno any ideas?
