[QUOTE=Albert;2129970]Quite right…It’s LiteOn Flash. It will work with some non-LiteOn drives, but they still must be based on a MediaTek chipset to have any hope. Your 1640 and 1655 are based on the Nexperia, as were most/all BenQ drives before the DQ60. You have no hope of properly using LtnFlash with the Nexperia. If you backed up any data from the 1655, it was probably not the normal EEPROM.[/QUOTE]
Thanks a lot Albert for the Info.
Ltnflash did actually write the wrong eeprom “the BenQ 1800” on the BenQ 1640 which ruined the drive.
I know that Ltnflash is supposed to work only with LiteOn drives and LiteOn based drives “the 1800 & 2000”, but then I thought I might try one last idea of flashing an “incomplete or not normal” eeprom from another working 1640 - since there is no eeprom backup and restore software for the Nexperia as far as I know -, the idea is that you can’t make a dead drive more dead or make it explode, right?
I know it probably won’t work, but I want to know I made everything I could reviving a drive I paid so much money and time to obtain.
