Recover system by editing sd card image?

Ugh, not my week with dietpi, i guess. After upgrading to v6.22 went fine with my vm, my live system rPi3b+ kicked the bucket. Upon reboot Wifi connection is lost and i have no means of connecting to the box. Ethernet cable doesn’t get a dhcp, HDMI out isn’t showing anything and does not appear to be working. Is there any way i can troubleshoot and or override a possibly crashed wifi by editing a file on the sd card? Or acivate hdmi? Or enable eth0?

Just to indicate the severity of my situation: i have to manually switch my lights in the bedroom on or off like some kind of savage :cry: :roll_eyes: :smiley:
