I've worked on rooting and installing custom roms on several droids. nandroid exited with status 31 is the first time ive seen this working on someone droid. i can not make a backup of current stock 2.1 in sprecovery 99.3b or i get that message.. also can not do update.zip to root.. was unable to format sdcard in windows while mounted, put sdcard in my droid and it let me format it. what could possible be the problem?
