I have no idea what happened, but after a update of Home Assistant OS it never came back online. I checked the SD card on my laptop and everything looked normal. I bought a new SD card and installed Home Assistant OS on it, tried to boot, nothing. doesn't show up on the network. Then I bought a micro HDMI cable to connect it to a monitor, booted still nothing.

Now I was trying to check this new SD card on my computer and it behaves very weirdly, always mounts as one FAD 32 partition (instead of the many ones it normally does) and I can't even wipe it with gparted, even dd-ing zeros on it doesn't do anything ...
