Can anyone send me the original firmware of Sony CRX195A1? If you have a Sony CRX195A1 CD-RW which was manufactured after Aug 2002, can you please use mtkflash to backup its firmware and email it to me (email@example.com)? I would truely appreciate your help. (One of the chipset inside my burner is marked as ZYU5).
One stupid thing I have done to it is I upgraded the firmware to LTR-40125S ZYS2, ZYS3, ZYS5 from http://www.firmware-flash.com/~dhc014/ without backing the original firmware first.
After first firmware upgraded, I found this burner can’t recognize any CD media at all, not matter blank or not. My PC can recognize this burner at BIOS and windows 98, XP , but it can not read any CD (keep telling to insert disc) . I have checked the driver and setting under windows, and found no problem. But it just can’t read any disc.
I guess my only chance to bring it back to life is to flash it back to CRX195A1 (must be A1 not E1) and maybe version ZYU5 ( I am not sure, I didn’t not remember).
