I recently flashed my benq from 1.6 to 1.9, but when it sent it...it said write verification failed...So i tried to erase the drive and flash back to stock and start all over again....Got it to go in vendor mode, but when i push the read buttom it says...Invalid Status 0x50??? I've tried reading...erasing..writing ...nothing always says Invalid Status 0x50... I even tried DosFlash...it finds the drive...but when i want to read, erase, or write it locks up??? Whats going on with this drive??
