Ok, so I bought a OnePlus One, and I have that working just fine. Soon after, someone gave me an old Galaxy S5 SM-G900V. Man, that thing is a pain to get rooted, but I finally did it. Another 3 days, and I successfully got LineageOS 16 nightly installed & working. I have Nethunter installed via the NH Store app. I also have Magisk and BusyBox working.

Now, I just need to track down a good Pie compatible kernel for "klte", or else figure out how to download source and build one.

Would anyone care to impart some (relevant) wisdom to help me in this endeavor?

Thank you!
