I have flashed many drives over the last 3 yrs successfully and now i've fried the laser on 3 Lite-on drives when using JF 1.55 i think. I am now thinking that it was the probe that screwed them up and they are prob 83850 lite0n drives. The newest version JF 1.66 has LO83 in it now so you can successfully flash them without a probe.
Too late for the fried lasers I have though.
I have a spare Benq How do I use JF to spoof the Lite-On key, inq, ident, dummy? to the Benq

just load the lite on dummy key into jungle flash, and spoof to ben q 1.6 fw, then follow regular procedures for ben q flashing...
but to my problem though. i erased my lite on, then i flashed it to 1.6, and now it wont read back ups or originals. and its a brand new xbox 360. i erased and reflashed to 1.5, and it didnt work. any idea why? the laser still lights up properly. and the disc spins(only for a sec), its not a bad key because i spoofed the the lite on to a sammy. i even did a pot tweak with no change in results
