Ok, since no one else will explain how to change the write speed to 8X, here we go (please note this has been explained before in other threads):
- Dump the firmware with a tool like Ltnflash or similar. You’ll need a binary dump (filename.BIN). I use firmware HS0K in this example
- Open the BIN file with a HEX editor like Ultraedit
- Goto position c021fH and change the value from 06 to 1E. This will allow the media to be burned at 2.4X, 4X, 6X and 8X. Make sure your HEX editor is in “overwrite mode”. You do NOT wish to append bytes to the firmware, just to replace existing values.
- Save the BIN file and upload it using Ltnflash, Mtkflash or similar tool.
The clever reader will know now how to mod write speeds of other DVD+R media by using this example. Actually the second last byte of each DVD+R entry in the firmware holds the key to the write speeds.
0x01 = 00000001 = 1x speed
0x02 = 00000010 = 2 x or 2.4x speed
0x04 = 00000100 = 4x speed
0x08 = 00001000 = 6x speed
0x10 = 00010000 = 8x speed
This means that 0x1E value equals 00011110 for media allowed to burn at 2x to 8x speeds, including 6x.
Good luck - and be carefull out there Don’t mess up your drives now.
BTW Please note that modding DVD-R requires another approach.I have explained this before so do a search in the forum for instructions.
