i usually flash using the method soso explains in a great little tutorial around here somewhere. it goes like this:
prepare firmware with fw toolbox (spoof and key)
create usb drive with xtreme boot maker
delete Xflash, Xread, Samtool, Xtremefw.bin files from USB
boot from usb and use these commands to flash:
to read - mtkflash r /m orig.bin
to write - mtkflash w /m hacked.bin
i did just this but it doesnt seem to work. i havent updated fw since the first rev of ix1.2 came out, so maybe i missed a trick. do i need to use iprep or something?
just reinstalled my via6421 using the latest drivers, so that should be all good i think
