I tried using the recovery image to reinstall SteamOS after upgrading the storage in my Steam Deck, and something went horribly wrong. Etcher refused to write the disk, so I had to use the command line to mount the image. On top of that I had to edit the command because the file name for the image does not match the documentation on their website.

After all of that, I made it into the recovery disk, but the screen went black partway through the installation, and then when I tried to boot it it told me that the operating system was corrupt. It has ChimeraOS on it right now, so it’s at least somewhat functional, but I’d love any advice that anyone has about the original OS.
