I've been using CrDroid on my Poco F2 Pro (LMI) for a long time now , have also dabbled with Elixir , Nusantara and a few others which was fun, I love custom roms and tinkering plus MIUI sucks badly.
Also the mire I tinker the deeper I go, I made my first magisk module this year , git pretty good at debugging and root files etc , plus I can restore my phone pretty fast now (I brick it every now and then lol)
This year I also got into battery replacement , I switched out my battery and my camera module, and switched out a samsung s9 plus battery, was pretty fun.
