Hex here+ rover bricked - how to access Pins for Reset and/or Safeboot?


While playing around with u-center software I disabled the UBX protocol for UART1 in.
So the rover is not configurable anymore. Its not even possible to flash the firmware again.
In the u-blox forum I got recommended to start the device in safe mode by putting PIN 1 to LOW.

However, I have not clue, where PIN 1 can be found on the board of the here+ rover. (The one with the M8P chip)

Can anybody support?
Any ideas how to do a hardware reset to factory settings?

Best regards,
