How to Root & Unlock Bootloader on Galaxy Note 4!


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!)

I do recommend following this guide on Android 5.1.1 though if you can as that way you will have exactly the same platform to start with.


Step 3. Tap on “Build number” 5 times untilit says, “Developer mode has been turned on”.


Step 4. Tap the back button once and tap on the new “Developer options” menu.


Step 5. Make sure “USB debugging” is checked ON.


Step 6. Goto and download Kingoroot app and install it.



Step 7. Connect your phone to your computer via micro-USB cable and download the following files:


Download BETA SuperSU v2.74 

Download (unzip into fastboot folder)

Download ODIN (unzip into ODIN folder)

Download samsung_unlock_n4-2

Download Samsung USB drivers

Download TWRP for Verizon Note 4

Download Oscar Kernel

Download Android 5.1.1 Stock Firmware for Verizon Note 4 SYSTEM ONLY


Step 8. Open up a command prompt or terminal (for Mac or Linux) and type:

For Windows:
cd Downloads
cd fastboot
adb devices

For Mac:
cd Downloads
cd fastboot
chmod 755 *
./adb-mac devices

For Linux:
cd Downloads
cd fastboot
chmod 755 *
sudo ./adb-linux devices

After typing it, make sure you go to your phone immediately and check “Always allow this computer” and tap on “OK”.  MAKE SURE YOU DO THIS, VERY IMPORTANT!


Step 9. Next, type:

For Windows:
adb push samsung_unlock_n4-fix /data/local/tmp/

For Mac:
./adb-mac push samsung_unlock_n4-fix /data/local/tmp/

For Linux:
sudo ./adb-linux push samsung_unlock_n4-fix /data/local/tmp/


Step 10. Go back to your phone and run KingORoot app and tap on “One Click Root”.  This will give you temp root to allow you to unlock the bootloader.



Step 11. Go back to your command prompt and type:

For Windows:
adb shell
cd /data/local/tmp/
chmod 777 samsung_unlock_n4-fix
chown root.root samsung_unlock_n4-fix

For Mac:
./adb-mac shell
cd /data/local/tmp/
chmod 777 samsung_unlock_n4-fix
chown root.root samsung_unlock_n4-fix

For Linux:
sudo ./adb-linux shell
cd /data/local/tmp/
chmod 777 samsung_unlock_n4-fix
chown root.root samsung_unlock_n4-fix

Watch your phone’s screen carefully while you do this, you may have to hit “Allow” if Superuser request window pops up although I did not have to.



Type “Yes” quickly.



Step 12. When it is done, you can pull the battery, put it back it then hold down Volume Down, Center Home, and Power buttons together to get into Download Mode.  Hit Volume Up and it should say “Mode: Developer”.  If you see this, CONGRATULATIONS!  You have permanently UNLOCKED the BOOTLOADER!

If you do not see this, you will have to repeat Steps 10 and 11 until you get it.  Don’t worry, the first time I did it it took me 2 tries.


Step 13. Connect a micro-USB cable from your phone to computer.


Step 14. Open ODIN program and select AP, then choose the TWRP file you downloaded earlier and hit “Start”.  This will install TWRP custom recovery.


Step 15. When your phone’s screen turns off, immediately hold down Volume Up, Center Home, and Power buttons together until you see “Recovery booting” at top-left corner of the screen.

If you missed it, simply take the battery out, put it back in and do the buttons.


Step 16. Once in TWRP recovery, we will need to format the microSD card as it has been corrupted during bootloader unlock process.  Choose “Wipe”.


Then choose “Advanced wipe”.


Check “Micro SDCard” and swipe to format your microSD card.


Step 17. Go back to main menu and tap on “Reboot”.


Then tap on “Download”.


Reconnect the micro-USB cable.


Step 18. Your phone will end up in a bootloop unless you re-install system stock firmware files as unlocking bootloader messes them up.

Open ODIN program and select AP, then choose the stock SYSTEM-ONLY Android 5.1.1 firmware you downloaded earlier and hit “Start”.


Step 19. Once done, your phone will reboot into TWRP recovery, just tap on “Reboot”.


Then tap on “System”.


Step 20. Once rebooted, copy over the BETA SuperSU and Oscar Kernel files to your Note 4’s internal storage.


Step 21. Power off your phone and reboot into TWRP again by holding down Volume Up, Center Home, and Power buttons.


Step 22. Once in TWRP recovery, install the Oscar kernel and SuperSU zip files.




Then reboot.


Step 23. Once rebooted, you should have a fully working Android 5.1.1 working on your Verizon Galaxy Note 4 with full root!

Verify you have full root by installing and running Titanium Backup app from the Play Store.  CONGRATS!
