Crossflashing DVD8601

[core2kid]

I have a Phillips 8601 that came in a Dell Dimension XPS Gen 3. My computer is now out of warranty so I want to try to crossflash the drive with the BenQ DW1620. I've seen this thread but I cannot seem to hex edit it correctly and the 2nd link doesn't work. Can anybody help me in crossflashing this drive? As of now I can't burn -R/RWs and I can't burn faster than 4x.

What to do to crossflash (which I can't figure out)

I have successfully transformed my Philips DVD8601 into a Benq DW1620. Here's what I did: Obtain a copy of B5G9.zip which contains B5G9.exe, a Windows program to update the firmware of the Benq DW1600. This is available here - http://support.benq.com/files/...rmware/DW1600/B5G9.zip Use a Hex editor on B5G9.exe to change the checksum of B5A9 (the checksum of the original Benq DW1600) to 6D11 (the checksum of the firmware in the Philips 8601). Details of the edit are Location: Original Value -> New Value F390: 42 -> 36 F391: 35 -> 44 F392: 41 -> 31 F393: 39 -> 31 Run the edited B5G9.exe. It will apply its firmware modification to the Philips 8601, turning it into a Benq DW1600. Obtain a copy of 1600-1620_B7K9.exe from the Benq Web site here: http://www.benq.com/ss_downloa...dvd-rw/dw1620/b7k9.zip Run this. It will update the Benq DW1600 to a Benq DW1620. Voila!
