Seek help

My car is the 2010 X5M s63b44a.

I just bought a BMS stage1 for the s63 harness a model with Bluetooth kit.

The Bluetooth kit is connected to one of the two red wires and can be connected to the mobile phone normally.



When upgrading firmware, I failed every time I reached 239 / 432. I've tried it hundreds of times.



At present, the device can be connected through a mobile phone, but it can't be used, so I have to remove it first.

I don't have a USB cable, only a mobile phone can connect with it. What's the solution?
