Old "how-to" info for Customizing/Building ROMs Still Relevant?

I'd like to start getting into customizing ROMs, and I'd like to start with the OH3 TW ROM. I'm wondering if all the older "how-to" threads that reference Android Kitchen and whatnot are still applicable to 5.1? For instance, most of the threads I find about Android Kitchen are (at latest) from 2013. Thanks!

Info about cm13 for the G2

Hey guys, most of us know that cm13 is in the works for our beloved G2, but I don't think many of us know anything about the development.
Do any of you have any information about how the development is going?

Phone tinkered with before, but not rooted. Need info on how to root it properly

Greetings! I need assistance rooting an LG Optimus F60 that has been tinkered with before. What I mean is, I had a guy unlock my phone since I switched carriers, and if I recall correctly( though not very sure) he used a few apps like kingroot to gain permission to unlock the device. He did not root the phone though, and I want to root it now(several months later).

The problem I stumble upon is that flashing SuperSU zips did not work. I have the app, but the binaries could not be pushed. I have tried manually pushing the binaries, but I was denied access...

I hope someone understands my problem and is able to help. I am more of a PC tinkering guy, never got into "hardcore" android customization, but I would really like to install apps on my sd card.
Thank you for reading, It should be solvable, and also sorry if my issue is common and/or has been posted before, I tried searching, but couldn't find anything(maybe I did not search good enough, sorry!)
