My RPI4 just stopped booting. Green ACT led blinks 4 times and the monitor stays dark, hard drives won't start.

What I've tried:

  1. I installed a fresh Raspberry PI OS to another card, that booted up, so the SD card slot is OK.
  2. I installed EEPROM BOOT RECOVERY to a fresh SD with Raspberry PI Imager, ran it, then switched to the original SD and I get stuck to this screen with 00000004 error:

Is there anything else I could try that would save me from having to reinstall everything?

    Most of us would break out our backup. Do you have one? – Unsigned_Arduino Nov 1 '20 at 17:48
  • Don't have backups of this one :/ – any_h Nov 1 '20 at 17:52
  • @any_h Were you able to figure this out? I'm running into a similar issue, but even a reformat of the OS didn't seem to resolve it. – matthewsteele Mar 24 at 0:54
