hi, the original firmware was stock 4.2.2 and i rootet the device. i wanted to install cm10.1 so i unlocked the bootloader. but i wasn't happy with cm, so i tried to flash stock rom 4.1.2 using flashtool and ftf (for sgp312, but without loader.sin). now the tablet reboots constantly. maybe this is because of the missing loader.sin? how can i fix this error? m.
