I just got the 6S02 firmware, extracted by boskin, I think it was, and tried it on my 48126S (with a 2S0D fw). I backuped it up and all that using a bootable floppy disk with the command line:
mtkflash “3” r /b /m 2s0d.bin
It finished and told me to restart, so I did. Then I did the actual flashing with:
mtkflash “3” w /b 6s02.bin
It flashed it alright I think, and told me to restart. I did and took out the floppy. When windows got me to desktops, it showed the new hardware detected thing, and said it was a 52246S. Well I thought mission accomplished rite? Wrong, then XP gave me an exceptional error screen, the one in blue, telling me to restart if this was the first time it ever happened, if it repeats blah blah blah. I restarted and it stayed, also during the detection of the writer.
So I flashed it back to a 48126S and the problem went away.
Anyone know why this happened?
