Problem:
Tried to read a BMW 2022 Getrag 7DCT300 ECU with Xhorse Multi Prog but failed. Multiprog says it does not support this boot version.
Solution:
This is a 2022 model. This boot version bc7g0301 is encrypted/locked.
Multi prog cannot read it.
Other tools like Hexprog, or Alientech KESS3 don’t read it either.
