I bought a new mainboard for my ageing JV22.
got all the software, FWupdate tools, ROM's and PRM's,
but it seems that the Firmware 7.00, which is on the board,
doesnot like to be or cannot be downgraded to a level where I can download the correct ROM to the new board.
Does anyone knows the way to get it done?
