For the bootmode read/write exploit, this was patched by Bosch in ~August 2020. This was a global update for all of their ECUs, for all manufacturers (VAG, Mercedes, BMW, etc). This even effects new MEVD17 ECUs (previous gen Bosch ECU) like what's in the F87 M2. This was presumably to keep their customer's happy since they likely got the contract with various OEMs partially due to their updated/upgraded security features implemented in the MG1 family of ECUs.
If you or anybody has any questions about any of this feel free to ask.

Can you help me understand this? Does this mean that if I take my unlocked ECU to the dealer for an update (which I have done before and they locked it so I had to get my ECU bench unlocked) they will lock it and this global update will lock my ECU with this new unlockable update? Or is this for all new ECU manufactured after August 2020.
