[RPi5] No boot after EEPROM update

I was working on trying to resolve another issue when I saw that there was an EEPROM update in LE 12.2.0 for my RPi5, so I decided to do that to see if it would help. Unfortunately, I don't know the version I was on, nor the version it was updating to.

Now, it won't boot at all. I get 3 quick green light flashes and one slow one which, according to https://www.raspberrypi.com/documentation/…ing-flash-codes is "SPI EEPROM error - Pi 4 and Pi 5".

How do I recover from this?

Thank you HiassofT

I just did that, I selected 2025-05-08-2712 for my RPi5, wrote the unzipped image to an SD card using Etcher, pulled the power from the Pi, put the card in, then plugged power in.

Now I've got a bright green screen and the power LED is rapidly blinking green non-stop. After a few minutes, it seems to have shut of video output as my TV said "no signal".

Thinking that the problem was probably with the 2025-05-08 version to begin with (since that's the newest one at the page you linked), I've now attempted to do the same with 2025-0-10-2712 (both are the SD version, since I boot from an SD card), and I've got the same results.

There doesn't seem to be much in the way of instructions at that GitHub page on what to do and what to expect... Is this the expected result? Do I simply power down, replace it with my (previously functional) libreELEC SD and reboot?

YES. I powered down, put my Kodi SD card back in & booted and it came up.

Thanks again! The GH page could use a little added clarity, but with your pointer, I now have a booting machine again.
Now, back to my original issue...
