Hi 9no, thanks for the PM. MTKWinFlash is not for DVD writers, just DVD-ROM and CDRW drives. Here’s what to do to restore your DVD writer.
This is the procedure I recommend to restore your drive:
1/ create a bootable dos disk. Remove all files except command.com, io.sys and msdos.sys (the system ones)
2/ download mtkflash 1.80 from http://dhc014.rpc1.org/howto.htm
3/ Add MTKFlash.exe to the disk.
4/ Get CS0P.BIN from http://codeguys.rpc1.org/firmwares/dvdrw/stock/1653S.CS0P.stock.rar.
5/ Add this to the disk.
6/ Select the jumpers on your drive for master and remove all other drives.
7/ Boot to the floppy while holding the drives eject button.
8/ Type in MTKFlash 3 w /b /m CS0P.BIN. The 3 is secondary master. See the step 2 site for details.
After all of this you will have to flash your drive (under Windows) with the crossflash patched firmware or 1613S firmware, otherwise the drive will not work properly.
Hope this helps…
