I was also referring to the issues with ecu flashing that some of the newer G20s had restrictive dealer software bricking their cars when ECU flashing.

Ahhh yes. That makes sense. I’m actually thinking of getting new tires and storing the OEM RFTs to put back on when my lease is up.
And yes. My car was bricked when I tried flashing it with BM3 back in December. My car had the updated DME software but no one knew for sure back then if BMW was doing updates. Also, there was no one unlocking these DMEs then. I had no other option but to return it and get a JB+ instead. I wonder what times BM3 tunes G20s are getting.
