I did some detailed cleaning of my full unit by removing cover, unmounting fan and taking dust out.
By doing so I realized it's not necessary, because most of dust stays outside and it's enough to make sure that visible side edges of radiator are clean. Anyway...
My PI board stopped booting now
I tried re-flashing with Apollo image, Armbian image (for Orange Pi4), but I still get no HDMI output. Red and Green LEDs are lighted up (w/o blinking).
Do I need serial cable to investigate or is there something I can do without cable?

UPDATE: I can boot Apollo, but it takes ages (about 30 minutes).
SDD drive is not mounted automatically. I can do it via mount /dev/nvme0n1p1 /media/nvme. I cannot save settings through UI - I get Internal error.

There are strange errors in DMESG (I listed all in red):

Is there anything I can do with this?
