Just did this with 2 different consoles (1 BENQ and 1phat liteon)
Followed these steps, as I still have my keys from both consoles. Both consoles are NOT updated as start of procedure.
1 - remove DVD drive from console, flash back to stock (using firmware from pack - pre-update OFW)
2 - put dvd drive back into console
3 - boot console up, connect to live
4 - get prompted for update, proceed to update (takes a bit)
5 - once update is complete, shut down console
6 - remove dvd drive, flash to ix-lt1.9 (remember, I have my keys saved, so this is simple in JF)
7 - put dvd drive back into console
8 - boot console back up, connect to live, and put in a burned game (for this, I used MK)
9 (optional) - checked xval flags, all seemed normal.
Everything seemed to go smoothly on my end, but then again, the biggest part of this is making sure you have your keys.
Burning off a new copy of MW2 as Ive been missing shooting people in the head and I feel after about a month of not playing, Im gonna be RUSTY!
