Root T889UVBMB4 4.1.2 Jelly Bean Update on T-Mobile Galaxy Note SGH-T889

Those who wants to root or even lost root after the latest Android 4.1.2 Jelly Bean T889UVBMB4 on T-Mobile's Galaxy Note 2, you can now still root using the MrRobinson's root method that no longer trip the binary flash counter and or using Chainfire's CF-AUTO Root. So, just choose between the two rooting options which you are already familiar with or you have it tried already and proven works perfectly before.

This rooting process is a little bit tricky for beginners but it's definitely worth a try for those who wants to get root access on their devices. Rooting is only needed if you actually wants to install an apps from Play Store that requires root before you can put it unto your device.

Warning: You should always remember that rooting voids the warranty of your device. If you don't know exactly what this is all about then leave your device untouched.

Disclaimer: Use of the files is solely at your own risks. The Developers of this root files and including US providing this guide shall not be held responsible if any undesired outcomes may occur to your device. Proceed at your own risks!

Please prepare some extra-precautions before proceeding, only fools rush-in.

• Back-up all important files stored from your device such as messages, contacts, emails, music, videos and etc. Although, some flashing method may not wipe your device data but there are circumstances that it will all deleted. So, better prepare than sorry, do this first. You can use any back-up apps from play store to do this task easily.
• Make sure the battery is fully charge before doing anything.I don't recommend for just around 50% charge this time, make it full.  Android 4.1.2 stock ROM now has gone very large and flashing may takes much longer as expected.
