I am the ECUHELP KT200II user, it´s Zafira A X20DTH EDC15M, i wrote various maps files in this ecu without problem, but the last file was corrupted, and now ECU not respond. OPCOM not have answer of ECU. What is the problem, and the solution? It´s bricked but only OBD write support, how to restore? i try to restore with kess v2, but, the same problem, ecu fails.
Possible Reason and Solution:
Cheksum errror
Do you need desolder X2 flash memory
29Cxxx
Calculate checksum
Separate file
And write with KT200II
