Reanimate my BPI-M5

Hello community,

I need help with my M5 board that is in an unknown state. When I connect UART Debug I can only see one line printed on the terminal. How can I fix the board? I want it in a running state, preferred would be to install CoreElec on SD or eMMC. Please help me get to this state. What can I do first/next?

I managed to burn the BPI Android Image onto the eMMC via burnttool as described. Had to do it from a physical F**** Windows machine, Windows VM was not working.
