HD DVD 740i not working at all

[qanda]This thread is about the HP DVD740i. Click here to see full specs[/qanda]I flashed my HD DVD740i to an GSA-4166B 1.02 and it worked but when I reflashed back to the 740i firmware I think it failed and the drive won’t boot at all now and freezes anything on the channel its connected to.

Any Ideas people

Connect into another computer/PATA and try to flash in REAL DOS mode.
