How to upgrade your FRsky Receiver firmware (X8R, X4R, X4R SB)

I just burned my X8R. Well, at least that’s what I think as it won’t power up anymore after “firmware update error”.

Why? - The GND and +Vcc pins on your picture are swapped (on Taranis picture). The +Vcc pin is in the middle.

Anyone has a spare XC6201-332?
