XHP connection help

I have a 2017 m240 and Iíve been trying to flash on xhp and it keeps saying flash failed unexpectedly midway through it. Now itís stuck in drivetrain malfunction.

just curious if this has happened to anyone and found a fox for it.

Iíve tried so many different thing and Iíve followed the protocols and made sure ignitions was on, accessoryís off, seatbelt on. also have a battery charger on it running 13v at 30-40amps

Iíve also made sure to put phone in airplane mode and made sure I was connected via mhd (black wifi adapter) also on a iPhone 13 currently running iOS 16 debating software upgrading to 16.6

This happened to me when I tried to flash back to stock with the XHP app. My car was stuck in some mode and it would not start. I hooked up a battery charger for a few hours. Then went back to try again. It failed a few times in the same way but eventually the flash went through. I don't know what the cause was but my advice is just to keep trying until it works (since that's what worked for me).
