specify what device

I guess that would help haha. I'm a little confused on it. I bought it new in box from a carrier as a Motorola Moto X. It's a first gen. The phone says it is a Moto X in the info part of settings. However, when connected to a computer, it says XT1039, which seems to be a Moto G.

I plan to start with first gen Moto X.

It could be someone’s barely working proof of concept

This may be fine, the phone is old enough it no longer connects to networks (US CDMA phone...). I am primarily looking to use this as a learning experience before getting real with my current phone. I guess it will be my own proof of concept 🤔

Good luck, compiling Android is a major pain in the ass.

Ya, that is what it seems. I was trying to avoid that for my first time but maybe this won't be the phone to do it with. I'll look at XDA forums.

That is for the help 🙂
