For those users of the AT&T variant of the Samsung Galaxy Note 2 (SGH-I317) waiting to experience the new Android 4.2.1 Jelly Bean on their devices, here’s some good news. The device can now be updated to the new firmware using CM10.1, the popular custom ROM from the CyanogenMod Team.
The Android 4.2.1 Jelly Bean includes 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 and miracast display, to name a few.
As Android Jinn pointed out, the CM10.1 custom ROM is currently in the nightly build stage. Therefore, chances of flaws are high. However, all these issues are expected to be resolved as development progresses.
Here is a tutorial explaining how to install CM10.1 Android 4.2.1 Jelly Bean on AT&T Samsung Galaxy Note 2 with the model number (SGH-I317). But before trying out the process, the users are recommended to take note of the following vital aspects:
- Backup your data.
- Ensure the device has at least 80 percent battery power.
- Ensure the USB Driver is installed for Samsung Galaxy Note 2 in your PC.
- Enable USB Debugging by going to Setting > Developer options > USB Debugging.
- Ensure your device has ClockworkMod Recovery installed.
- Backup your EFS Folder.
- Don’t skip Nandroid backup as it’s very helpful if this custom ROM doesn’t work the way you wanted.
- In case you get stuck on boot or experience boot loop, perform wipe cache partition and wipe dalvik cache a few more times before rebooting.
- Never restore system data using Titanium Backup. Restoring apps and data might cause severe problems.
The users should also remember that this tutorial is meant only for Samsung Galaxy Note 2 (SGH-I317). It should not be tried on any other Android device.
