How to Root Note 8 N950U on AT&T, Verizon, Sprint, T-Mobile.


Note: 

1# This will only work on the U.S. version of the Note 8, powered by the Snapdragon 835. If you’re using a Note 8 feature Samsung’s own Exynos 9 series CPU — essentially, the model sold outside the U.S. — look elsewhere.

2# You’ll need a PC to unlock your smartphone.

3# The process described below erases whatever’s on your Note 8, so backup anything you need off the phone before you start.

4# Because of the boot.img we are flashing, there’s a good chance the battery will never charge to more than 80 percent.

5# Rooting your phone voids your warranty (though you can unroot your Note 8, restoring the stock firmware).

6# You root phones at your own risk, and it’s something the average smartphone user shouldn’t really mess with.

2#  Open the newly extracted Odin folder and double click the Odin .exe file inside.

6# Click the Options tab and make sure all of the following are checked on (and everything else is not checked).

# Auto Reboot

# F. Reset Time

# NAND Erase All

# Re-Partition

7# Click Start and wait for the phone to flash. It will say FAIL at the end, but it still worked.

8# Put the phone back into Download Mode by holding down Volume Down, Power and Bixby buttons at the same time and keep holding them until the screen says you are in download or upload mode. (If you wind up in upload mode, hold the same buttons again to get into download mode). The phone will tell you it is in emergency mode, which is fine.

9# Click Reset in Odin.


10# Click on BL in Odin and select the BL file inside the newly extracted folder. Then click AP and select the AP file. Click CP and select the CP file. Finally, click CSC and select the CSC file.

11#  Click on the Options tab and select the following ONLY and uncheck everything else. (Take note: this list is different from earlier so make sure to review exactly what you’re checking.)

# Auto Reboot

# F. Reset Time

12# Click Start and the phone will reboot into recovery mode. Check to see if it says Failed to Mount /System (Invalid Argument). If it does,you did something wrong and need to start over from the very beginning. But if there’s no message along those lines, you can continue.

13# Using the volume buttons to navigate and power to select, choose Reboot to System.


14# Once the phone boots up, go through the normal setup process.

15# Once you can get to the homescreen, open the SuperSU app from the app drawer. It'll prompt you to update binaries.

16# Select Normal Method, and then follow the instructions to disable Knox if a message pops up instructing you to do so.

When SuperSU is done, you’ll be told to reboot. Allow your phone to do so. It'll reboot a few times and once done, you're all set. Enjoy your new-found root access.

To fix any issues caused by that, you need to add the fsck.ext4 file to the /tmp/ directory and tun it. This can be done easily by our newly found root (su) powers on the device. Follow the instructions below:

2# Setup ADB and Fastboot on your PC.

3# Enable USB Debugging on your Note 8:

# Go to device Settings » About phone » Software information » and hit the Build number field seven times to enable Developer options.


# Go back to Settings » select Developer options (below About phone) » scroll down a bit, and tap on the USB debugging toggle to enable it.

4# Connect your Note 8 to the PC, you may see a pop-up asking for your permission to authorize USB debugging, be sure to allow it.

5# Open the folder where you saved fsck.ext4 file in Step 1 above, and then open a command window inside this folder. To do that, “Shift + Right click” on any empty white space inside the folder and then select “Open command window here” from the context menu.

6# On the command window, issue the following commands:


7# Your note 8 root complite.
