Spent about an hour talking to MINI assist today. They suggested and tried various things that are already discussed here without much luck. They think above link reporting incorrect trim is probably not relevant to the issue since mini app reports correctly. One thing they wanted to try but couldn't is to restart/reboot system after updating services via holding down volume knob but that didn't work. Is there a way to restart/reboot system ? I didn't find any steps in the manual besides "Confirm system restart" in updating/restoring software via USB section.
