My jumper displayed a message after use of master slave mode.
It wrote "too low battery can't save"
The battery was set on 12V, I tried to flash and impossible, so I put 12V and same issue. I retried to flash after that and now nothing happen the screen is black and the usb mode is now unavailable.
