Additional information

P.S. Fedora Media writer DOES NOT allow flashing images to SD Cards unless SELinux is set to Permissive.

I also came from the Stock ROM before installing pmOS. Here's what I did:

1. I had the m0 on the latest version of the Stock ROM (4.3) before I went through the motions of installing pmOS as per the wiki page.
2. I installed a custom recovery (TWRP) with Heimdall.
3. I constantly had to switch from Fedora 36 to Ubuntu 22.04 due to Fedora 36 not understanding how to open img.xz files.
