CM10 (CyanogenMod 10) was announced a few days ago where Cyanogen told that not many changes will be required when moving from CM9 to Cm10 for current developers who have their custom ROMs. Asus Transformer TF300T is one of those first tablets that have received the first CM10 Android 4.1.1 builds.
In this tutorial, we will tell you how to install CM10 Jelly Bean 4.1.1 on Transformer TF300T. This is a custom ROM, not an official update by ASUS. Since this is a very early build, there are many things that are not working yet. We have a full list of working and not working features below.

What doesn’t work:
Make sure you have installed all your USB drivers for the Asus Transformer TF300T to connect it with the computer. Download ASUS Transformer Pad TF300T USB drivers! Apart from just the USB drivers, there are a few more things that you need to take care of.
1. You need to enable USB debugging mode. This helps to connect your Android tablet with the PC. See here: How to Enable USB Debugging.
