Angry Jb4 refusing connection with phone and has deleted firmware - 09-14-2021, 06:58 AM

I have had nothing but trouble with firmware updates from day one I have had a bit connection code and have had problems updating the firmware. I messaged bms a week after I got my jb4 about the code and the fact I couldn't update the firmware but never received any response. Now this issue had my car in paperweight mode in my driveway someone please help me before I lose faith in this POS tuner. I also have no steering wheel controls to even try to disable the damn thing..
