One user feedback: ECUHELP KT200 read Bosch md1cs003 (0281037101) OK, but when writing a new file got ERROR ERASE (shown as the following images).
Car Year: 2021
Ecu year:19/10/202/
When writing the original file it shows ok.
but this is not accurate since no difference in the file, the tool writes new data only when there is a difference the written file address.

Possible Reason and Solution:
your file is bad
Try to write original if he writes original
Your edited file is not good..
You are trying to erase something that should not erase.

Finally.
The ecu in the video is 0281035, KT200 also works for me, but don’t works on a newer ecu version 0281037.
