How to root the Samsung Galaxy Note 2 [GT-N7100/GT-N7105]

Users of the Samsung Galaxy Note 2 GT-N7100 and GT-N7105 have an awesome treat waiting for them from XDA Developers member Chainfire.  If you own a Galaxy Note 2, you can now root it easily through Chainfire’s CF-Auto-Root package.

According to the dev himself, this package will only root the phablet, but not tamper its recovery.  In fact, you’ll be getting SuperSU (both binary and APK) and retain stock recovery on your phablet.

Chainfire’s previous rooting packages, known as CF-Root, were known for the ease with which they can be flashed onto a phone.  CF-Auto-Root is no different.  The instructions are simple and easy to follow. Just make sure to check your phone’s model before you attempt this procedure.
