I've flashed my hitachi 79 drive using the toolbox 4.6 and the .wav trick to unlock. I was able to dump and flash, and received an "OK" when it was done. I ripped a couple of my games with wxripper, and when i burn them with either XBC or imgburn, i get the error on the xbox of "Please insert this into an xbox360 to play" I'm using verbatim dvd +r dl discs.

I can still play my originals and dvds, so im not sure where the issue is.

well, i had burned about 6 discs using different settings in XBC. i had originally flashed my 79 with 8x firmware, re-flashed with 12x, and the pile of backups all worked.
