First and foremost, I nor @infected_ are responsible for what you do to your device and YOU accept full responsibility if there are ANY issues.
IF there are any issues please don't blow up @infected_ 's threads looking for support because you will find none. Please just do some research first before posting an issue. Since this is an Alpha build, someone may have already posted a fix for an issue your having in one of the i9100 threads.
I have personally tested this rom out and everything seems to been in working order. I may have missed something though so please don't quote me. The one thing I have noticed is the Battery Percentage is not correct.
Rom: Build 11/23/2013
First make a nandroid backup (DUH)
Make sure you are on the newest CWM recovery. These easiest way i do this is flash the newest CM Nightly
Once you flash the newest CM Nightly, reboot recovery

WIPE DATA/ FACTORY RESET (If you don't you will get stuck on CM Logo)
