Help!! FOCBOX Unity / Xenith cant connect after firmware update

[xsynatic]

For the focbox singles:

For the unity: the black connector where the bluetooth modules is installed, see below.

@DSluijk

How do I do this?

1. Disconnect the unity from the battery and any other connectors.
2. Remove the orange cover.
3. This reveals the unity with a separate PCB on top. The separate PCB is the Bluetooth module.
   
   
4. Remove the Bluetooth module. Take note of the connector the module is plugged into.
