I used the s1fwx to backup my firmware before trying other firmwares for my mp4, And now i can't upload it back to the player, I think maybe it just a partial backup or something.....
none of the 30+ firmware i've tried bring the player to show any picture on his screen, Only one firmware turn on the screen but no picture.....
If i buy a new machine exactly like it, What tool can i use to backup the FULL firmware of it to transfer it to the "dead" machine ?
Any one has the same chipsets ?
