I’ve bought a benq 1640 yesterday, and tried to upgrade the firmware.
But I didn’t know the difference between GSHB and BSHB version and
tried the GSHB downloaded from some website in korea.
After that, burning programs have not reconized the device , so I tried to back to the retail firmware but faild.
I attached the error image.
And I tried the BSGB cvt file with Windwflash but failed.
Currently I attatched the device to my notebook thru 1394 card because I am in my office.
Dos program, benqcvt.exe seems not to recognize the 1394 connected device , so I cannot try the dos program.
any help please…
