Two things I’m currently working on:
Ubuntu Touch on my old Nexus 6P, just to see how it’s coming along. I did need to reference this comment in order to get mine booting properly.
LuneOS on my old HP TouchPad… Which is giving me some problems. It started off rough because I was trying to find some files that were released between 2011-2014, & then trying to get them running… Then once I finally got that done, I still wasn’t able to get LuneOS to boot. Here are some of the files I collected while working on this:
