No distro works, what am I doing wrong?

On my Renegade ROC-RK3328-CC, no distro seems to work.
Today I tried to install almost every one of the officially supported distros and none worked. Here is the list, of what I tried:

  1. Debian 12: Green and red LED light up, but the green one turns off after about half a second. The red one stays on.
  2. Debian 11: Green and red LED light up, but the green one turns off after about half a second. The red one stays on.
  3. Fedora IoT 42: Both LEDs stay on, but nothing shows on HDMI.
  4. Ubuntu 23.04 base: Green and red LED light up, but the green one turns off after about half a second. The red one stays on.
  5. Raspbian 12: Green and red LED light up, but the green one turns off after about half a second. The red one stays on.
  6. Batocera: Both LED stay on, but nothing shows on HDMI.
  7. LibreELEC: Both LEDs stay on, but nothing shows on HDMI.
  8. Lakka: Both LEDs stay on, but nothing shows on HDMI.
  9. Armbian 25.2.2 IoT: Boots, but it just will not, under any circumstances, connect to the Internet. I have it connected to LAN, but it consistently says, it can’t connect.

Everything was simply flashed onto a SanDisk 128GB Ultra microSDXC with the gnome-disks utility.
I don’t know what I’m doing wrong or what to do now. Please, can anyone tell me how I get Debian 12 running? (Preferably, my end goal would actually be to run NixOS, but it would be a huge step to at least get Debian 12 or any distro, for that matter, working).

Please don’t double post about the essentially the same issue. Rant about Renegade ROC-RK3328-CC

Closing.
