Did you try to use the DOS cvt flasher (or what is it called) from “Inofficial firmware” page (see thread above)?
BTW, to all others, yes he may have voided warranty, but after I saw what bad quality at least my BenQ was, I would understand him to flash back and get the drive replaces.
For me, this is a logical conclusion: As I often rant about, the European BenQ download site sucks. They still offer M firmware for Bulk and Retail. So I understand people going to US or whatever websites to get updates. BenQ was not able to tell me about their policy regarding firmwares and warranty. They were not able to tell me anything at all but “wait”. So I understand if someone just says “FU” to the support and helps himself - and I still think he has the right to return a faulty drive (as long as it was not his attempt to flash which destroyed it).
So RickDriver, while you may be legally right on that, I feel Viper is morally allowed to reflash the drive and if still does not work after that, to return it.
Viper, good luck!
