very strange.. so why these boards called 'encryption' if everyone can read it.. i always thinking that they are installed to read-write protection (copypaste protection)
A long time ago, there was no "KWP2000", "galetto 1260", "MPPS" and other tools to read the memory (with discret flashprom CI)... the only way was unsolder, read in a external programmer and write and solder it again.
