Powered by a dual-core 1 GHz processor and 1GB of RAM, the Samsung Galaxy Tab 2 7.0 comes with Android 4.0.3 Ice Cream Sandwich out-of-the-box. The device also recently started receiving the official Android 4.1.1 Jelly Bean firmware update.

Now, thanks to the talented minds of the CyanogenMod Team, users of the Galaxy Tab 2 7.0 (P3100) can try out the latest Android 4.2.1 Jelly Bean on their device using the newly released CM10.1 custom ROM.

The Android 4.2.1 Jelly Bean include features like multi-user support, gesture typing, new quick settings option, lock-screen widget, new camera app, photo sphere, improved Google Now, new daydream feature, miracast display and many more.

As noted by Android Jinn, the CM10.1 Nightly in question is an underdeveloped build and therefore may contain bugs. However, all issues are expected to be resolved as development progresses.

Below is a tutorial showing how to install CM10.1 Android 4.2.1 Jelly Bean on P3100 Samsung Galaxy Tab 2 7.0. But before that here are some pre-requisites to consider:

- Backup all your data including messages, Contacts and APN settings.

- Make sure your device has at least 80 percent battery power.

- Enable USB Debugging by going to Setting > Developer options > USB Debugging.

- Ensure your device is rooted and have ClockworkMod Recovery Installed.

- Don’t skip Nandroid backup as it’s very helpful if this custom ROM doesn’t work the way you wanted.

- This tutorial is only for Samsung Galaxy Tab 2 7.0, model number P3100. Don’t try this on any other Android device.

- The users must note that IBTimes cannot be held responsible if anything goes wrong. They should proceed at their own risk.
