HELP! while downgrading using pandora's battery an error showed saying it could not read system.dreg . When i use a normal battery to boot it loads firmware 1.5 but i get the blue corrupt screen. after i press o it comes back up again, over and over. is there something i can do to fix this?...i've tried doing something using the extended pandora's bootmenu v.84. i've tried installing cfw using the option but it always says cannot unnassign flash1 even after waiting as directed in the readme.
