Exchange of the firmware
The firmware chip is located on the side circuit board.
Carefully raise the chip by placing an appropriate tool between the chip and the chip
holder.
Alternately place the tool under the left and right side so the chip is raised evenly.
(A wooden spatula is best suited for this. Otherwise use a flat but wide screwdriver. You
can also use a special chip-gripper if you have one available.)
Carefully check if your chip lost any of it's legs!
f this is the case remove them from the holder before proceeding.
