In the video below, you can see how to access the internals of the Aethair PRO backplate. This allows you to:
Change the mounting bracket
Replace or repair the power cable (USB-C, 12V, etc.)
NOTE: When removing the plastic cover, take extra care to protect the top black connector. Avoid any bending or pressure on the connector, as even slight movement can weaken or disrupt its contact with the board.
