I think .20 was a build released for R2D2 version of D2 (??). Lots of ROMs included components from it...is .20 .320?
battery pull, factory reset, etc. just follow standard rom troubleshooting.
If you hold HOME button while booting do you not get the Android Recovery screen? (Press search when you see it)...how can i factory reset if i cant get to recovery?
yeah, just use an sbf at this point. it's what you were trying to accomplish anyway. I don't know why this happened, no matter what system version you have this shouldn't happen. My best guess is a botched flash.
