Hi,
When I launch the update via USB-C or Bluetooth I have the same fault:

What do you know about this error?
Thanks in advance

@hedger

I thought that the defect was the too small capacity of the 8GB microSD card, but I have exactly the same problem with a 128GB card. Do you know what the Firmware Update Error = [2-0] corresponds ?

I erased and did the update again, it works now

Same error here, and same solution: made a factory reset, and then the update worked.
Thanks, JyLy.
