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:
- I installed a fresh Raspberry PI OS to another card, that booted up, so the SD card slot is OK.
- 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?
