I know just enough to get me in serious trouble and should have left well enough alone.
I had managed to crossflash my Lite-on 1633 months ago @1653S CSOR. Read the some of the thread on CSOT/BYX5 and thought I'd see if that improved things a bit. I used the codeguys BYX5-patched-cf-mcled under the 1653 and executed it. Seemed fine so went to read a disk and about 2/3 of the way through crunching noise and disk stopped. Panic - so went back and reflashed with the CSOT patched cf for 1653 and all was good except drive would not now recognized any DVD burned on the DW 1670, it's own burns yes, but not the BenQ. So tried tried going back to the CSOR, no go. Now it won't read any DVD, CDs yes, but no DVDs. Tried going back to stock by restoring the EEPROM and f/w to the original BSOS and still no go. I probably did something wrong in the flashing of firmware and didn't make the back of the EEPROM as I should have before the above. But now at a loss as to what to do. I thought I read the instructions correct that if f/w stated patched-cf- I could just run the exe as is, but it seems not.
Guys it was almost a year ago that I did this the first time and can not remember what I did then.
Can someone please do a "flashing for dummies" and tell me how to get this fixed?
