Welcome to the Sony world!
But what's the meaning of our post? You want custom rom. Ok and now?
If you have a question regarding a particular rom, ask in the rom thread.
If you have a general question, post in Q&A
If you have to tell something general, post in General.
But this is dev section. Your post is nothing about development, so the mods will move your post.
Perhaps you could ask a concrete question - after the moving of the post.
btw, reading, reading and reading again - that's the quite hard job for users. You are not alone with this quest.
Good luck and much fun with your Z1.
