I was running HASSIO OS on Raspberry PI3+ but forgot login. So decided to write the image again on a SD card and start over.
Now it won’t boot anymore. Green led flashes 4 times slow, then 4 times fast.Tried to put it on SD card with both Raspberry tool as Balenaetcher. On 2 different SD cards.
Writing RAspberry OS desktop on same SD cards boots perfectly fine and gives me a usable desktop. So I presume bootloader and so is perfectly OK.
Did you wait at least a half an hour while HA is starting up? It should be working on RPI3…
You installed the correct version for the RPI3?
You already tested that your RPI not died, so that is not he issue.
I’m quite sure I used the correct version → 32 bit version for RPI3. I even tried the older 9.4 image from github instead of 10.1 which I had before when it was working.
Waited over an hour, but don’t think its doing anything due to the Green LED status flashes"
