How about this! I had upgraded to the Liteon 48x firmware on my 40x original Liteon drive and I just tried to flash back to the new VS0j firmware for the 40x using the VS0J.exe and the ZS0J.BIN that I created. It would not flash back. It said it did not find a qualfying firmware when I tried it with the *.exe version and with VS0J.BIN, it just ran through 1-100% one time only and did not upgrade.
Of course, I can flash back to an older 40x firmware and then upgrade to the new one but this shows that Liteon has caught on and is fighting back by not letting us use the *.bin file to an unlimited extent.
