Determine what fw to use by reading the F/W Rev on the drive properties section at JungleFlasher.
The 13146 update, writes stock fw on all drives except Hitachi and already locked drives, all phat lite-on drives now become 02510C, 9504 become 0272, all benq drives become 04421C and Samsung are just patched.
So, i guess the 025 one

(NOT 0225)
