…I cross-flashed my 1673S to a 1693S (It was a Sony DW-22A or DW-26A or something, whichever is a 1673S), and it worked fine for a few months. I didn’t push the write speeds past what they were at the 1673S level or anything.
Suddenly, I come back from Winter Break, and when I start my machine, my DVD burner doesn’t show up in Windows or the BIOS. I made sure cables are plugged in and everything.
It will open/close and the green light goes on when I put a disc in, but it won’t work.
The only reason I updated is because the 1673S firmware was giving me horrible PI/PO ratios, and coasters.
