While a host of Android devices have now received the latest Android 4.2.1 update via custom ROM Jelly Bean firmware, a select few now have the access to improved Jelly Bean features with the release of CyanogenMod 10.1 (CM10.1) ROM.

This time, however, the Android 4.2.1 Jelly Bean firmware has arrived for the international variant of Galaxy Note 2 N7100 thanks to CyanogenMod 10.1 aka CM10.1. CyanogenMod has always been known for its highly customizable interface that’s not present in stock ROM.

Few of the notable Android 4.2.1 Jelly Bean features available here are multi-user support, gesture typing, new quick settings option, lock-screen widget, new camera app, photo sphere, improved Google Now, new daydream feature, and miracast display, to name a few.

Before heading over to the process it is important to note that this CyanogenMod 10.1 aka CM 10.1 ROM is an unofficial build and still under development.

It is also required to remember that this tutorial is only for Galaxy Note 2, model number N7100, and trying it on other Android devices is not recommended. Moreover, the user will have to check this tutorial out at his or her own risk as MobilenApps is not responsible for any kind of damage incurred to the device.

Before starting, make sure that the device has at least 80 percent battery. It is also recommended that the user backs his or her EFS Folder and that USB Debugging is enabled. It is also important to get the device pre-rooted and to have a ClockworkMod Recovery installed, alongside running the stock CM kernel.
