Hello everyone!
I got my delphi clone ds150e and it seems to be broken. Every time I try to connect with my vw golf mk4 it lights up as it should be, connects with the car and the test goes: OK but the last communication test always fails (Updating firmware doesn't help). I disassembled it and what I found was it is double boarded and one of those boards is called tcs + relay v3.0. Looking carefully on it I found out that one one of the microchips is phisically broken. Its upper side has a small gap in it. This microchip seems to be stm8s903kt6c which is marked as u1003 on the pcb. I bought a few brand new chips and ST-Link v2 as well. Tried to do some soldering and I found out how to read and write successfully one of the new stm8. It seems I can't read the broken one (maybe because it's broken) and I can't find the firmware I should flash on the new chip to make my ds150e work. I would appreciate any help, any firmware and everything.

Thanks in advance.
