I am not a dev, and I don't know a lot about making my own Android ROM. But, I want to build CM10.2 for our tablet (Lenovo A2109). I have Ubuntu 13.10 64-bits ready, and I am syncing the repo right now. Is there anyone that can give me some direction? I am following tutorial from these forums: [HOW-TO] Building CM10, AOKP & TeamBaked For The JB Bootloader [Ubuntu 12.04+ 64-bit] - xda-developers COMPILE From Source For Any Phone On Linux Distros [BUILD ENVIRONMENT TO COMPILE] - xda-developers I know it is for a specific phone or tablet, but still, worth a try.
