After struggling to root my recently bought Verizon Note 4, I’ve finally been able to root and unlock the bootloader after about 10 tries. It is pretty easy to do once you know how to do it but it took me about a week to get this working correctly, mostly due to the fact that temp root was hard to do with KingRoot and KingORoot.
Anyways, I have been working on this tutorial so anyone can repeat it easily, if you follow step-by-step, you should be able to easily unlock the bootloader and root your Verizon Galaxy Note 4 SM-N910V!
Before we begin, BACKUP EVERYTHING as you may LOSE EVERYTHING if something goes wrong. Also, make sure Reactivation Lock is OFF if you turned it on before.
Also, you will need a microSD card inserted, make sure you BACKUP EVERYTHING on that microSD card as we will format it later.
Step 1. Install and run “eMMC Brickbug Check” app on Play Store.
Make sure your CID starts with “15” otherwise this root method will NOT WORK!
Step 2. Go into Settings->About phone and check that your Android version is 5.1.1 or less. (It may work on 6.0.1, I have not tried it yet but if you are brave enough, please try it and let me know!)
