This was read with external programmer, right? Not via obd interface, like ioterminal or trionic flasher.
Here, p0420 solved, checksum ok, bitswapped again to fit on your external programmer. If you read it in 16bit, write it back in 16bit and so on. If 8bit, write to 8bit.
Come back and tell us if works.
Pass sent in PM.

Ok. You can try my file. If you have doubts, just compare it with yours and see if is all ok. I hope your kess is a good clone.
P.S. DISCONNECT LAMBDA 2 PROBE
