Unable to flash image on BPI-6204

Hello, I am trying to flash BPI-6204 board. After flashing cs6202-install-tfcard-20240703_20240704_114350.img on MicroSD card and then to eMMC, following this guide, at the next reboot of the board nothing happens. The board has FN led always on, as well as the two blue led on the board, HDMI output doesn’t seem to work but network stack seems up (board gets IP from DHCP, but after portscan nothing seems running in it).

Could you help to troubleshoot the issue? Could it be some kind of hardware failure?
