1/ Download the firmware you want to modify.
2/ Start MCSE.
3/ Load the firmware .exe or .cvt file.
4/ To increase the read speed, simply click the increase read speed checkbox
5/ To increase the write speed, double click the media code you want to change and select the write strategy you want to use instead. This is a bit of trial and error. Check the Changing DVDÂ±R write strategies (results thread) to see if your modification has been tried before.
6/ Save the firmware
7/ Start the modified flasher or flash the .cvt file with WinDWFlash.
This, from ala42, is pretty close to what you will need. Make SURE you only flash the right drive.
