im not sure it uses a mediatek chip set mktwinflash dont display info about chipset


#2

What is the actual name as reported by tools like Nero InfoTool or DISC Info? Is it something like CDR-5W40, and also, what it the current firmware version?

Try making a backup of the firmware with mtkflash in DOS and send it to me please. The drive is probably upgradeable to 48/12/48
