Hello everyone. I have an 820-02773 board that chimes but displays no image—neither on the internal screen nor on an external device. It appears that the NAND chips on this board have been replaced previously. I placed it in DFU mode, but once the "Revive Device" process finishes loading, the application simply closes, and the board remains in DFU mode.
