Hi!
there is only CRUM, it is encrypted. Need a debugger for ARM (ARM7 Big endian), and memory map.

Ok, it is very interasting. I have four mfp scx 3400f, and  pay for one fix firmware, so it is ok. But I search for solution to change crum number. I have solution to use CRUM (chip) fix firmware and use on new printer and update firmware. After that is working fine.
