Did you have a tutorial or something you followed?
The last time I installed Linux was over 20 years ago when I repurposed an old Gateway PC to be a switch/VPN. I'm sure it's not outside of my ability but wouldn't know where to start.
Working on remodeling a motorhome and I want to build a few Home Assistant interfaces. If I could use my old M8 that is still in perfect condition that would be amazing.
Well basicly all instruction you need and it's explained pretty well on the lineage os website itself.

The hardest part was getting the unlocktoken since htc doesn't take new htcdev registrations. I got hellped by a member on Lemmy who had a old htc dev account.
