How to Flash TWRP and Root Galaxy Note 8 Exynos

This is a comprehensive step-by-step guide on how to install TWRP and root Samsung Galaxy Note 8 Exynos variant. This requires some extensive steps to flash custom binaries which in this case is custom recovery and SuperSU. However, as usual, we are going to make it as clear as possible so even a novice user can follow the steps.

Let’s start with just a little bit introduction. Samsung Galaxy Note 8, we will call it as SGN8, is available in generally two variants: the one powered with Qualcomm Snapdragon chipset and another one powered with Samsung Exynos. Nevertheless, since TWRP build is always cooked for a specific device, hence this tutorial is not applicable for SGN8 Snapdragon. It means that generally SGN8 devices released officially in American(U/A/T/P/V), Chinese(0/8/6), Hong Kong(0), Japanese(SC-*), Canadian(W) are not compatible. The method is basically the same and should applicable for those incompatible devices as long as the correct build of TWRP is employed.


Again, this tutorial is for SGN8 Exynos with codename greatlte with device code number N950F/FD/X/N. Mostly this variant is released officially for EMEA region including any countries in Europe, Middle East, and Africa.

Objectives

  1. Flash TWRP v3.1.1-0 on SGN8.
  2. Flash SuperSU to gain root.
  3. Flash Custom ROM (optional)

Prerequisites

You will need:

WARNING: We hold no responsibility of any damage or risk of broken device because of following this tutorial. Proceed with full caution. It is recommended to firstly read the article thoroughly. Please proceed only if you have been fully understood.

F.Y.I:

  • Root a Samsung Galaxy device will trip knox and void your official warranty.
  • As of now you will lose Samsung Pay and Secure folder forever if you root once, even unrooting won’t help.
  • OTA Update most-likely won’t work once you root.
  • To unroot your device completely, simply flash Samsung stock firmware.

Preparing Your Computer

Step 1 – First thing first, you have to disable Windows Driver Signature Enforcement on your PC/laptop. You can follow this tutorial or simply use this Disabler tool.

Step 2 – Assuming you have disabled Driver Signature Enforcement, now proceed by installing Samsung Standalone USB Driver that you have downloaded earlier. This is needed for your computer to recognize your phone and to establish ADB connection. Simply open up Windows Explorer and go to the location of where you have extracted the .zip file. Double-click the installer (.exe) file and proceed accordingly.

Alternatively, you can also use this ADB Fastboot Driver Installer or this Samsung Mobile Universal USB Driver if that one did not work properly.

Step 3 – Likewise, now you have to also install latest version of Odin v3 (at the time of writing it is Odin v3.12.7). The installation is really straightforward.

Step 4 – Now reboot your phone. This will make sure that all the newly installer drivers are loaded with the system.

Preparing Your Phone

Step 5 – Grab your phone. Open up the Settings app, and tap on About Device, then tap 7 times on Build Number. This will enable the Developer Options inside your phone settings.

Step 6 – Now you will see new option displayed in the Settings area called Developer Options. Find out OEM Unlock option inside the Developer Options and enable that option.

Done? Alright! Let’s continue..

Step 7 – Now turn off your phone completely. Next, while it is off, press the following buttons all at once for approximately 15 seconds. They are: Power + Volume Down + BIXBY buttons.

Step 8 – A warning message will be displayed. Read it carefully and if you agree to continue, please now press the Volume Up button. This will bring your phone to the Download Mode.

Flashing TWRP

Step 9 – At this point your phone should be in Download Mode. Now open up Odin v3 that you have installed.

Step 10 – Tap on the AP button in Odin v3 and locate the TWRP .TAR file that you have saved in your computer.

Step 11 – Now grab your phone and the prepared USB cable. Connect your phone which is still in Download Mode to the computer using the cable.

Step 12 – This is the crucial step. Please read it and employ it carefully. Next, press and hold the Volume Up + BIXBY + Power buttons together (do not release it yet) AND click the Start button in Odin tool.

Step 13 – Wait for the phone to reboot. DO NOT release the three buttons or otherwise you may not be able to reboot into TWRP recovery.

Setting Up TWRP

Step 14 – Once done flashing, your phone should enter TWRP Recovery at this stage. As usual, TWRP will ask you to do the “Swipe to allow System modification” action. However, DO NOT DO THE SWIPE!

Step 15 – Select “System /RO” option. Then go to Wipe >> Format Data >> Type yes to continue.

Step 16 – Go back to TWRP main menu and tap on Reboot, and then Recovery. This will reboot your device again into recovery mode.

Step 17 – Assuming your phone is now back in TWRP again and is still connected to your computer. Now transfer the downloaded no-verity-opt-encrypt-5.1.zip file from your computer to your phone. There are 3 alternative methods to do the file transfer:

  1. MTP method: Connect your phone with computer and just copy the zip to internal storage. It is basically similar to how you transfer files when in Windows system using Explorer – for the moment not working.
  2. ADB method: Connect your phone with computer (you did this already). Open up Command Prompt interface and run command “adb push /path/to/zip /sdcard/” – for the moment not working.
  3. Using External SD: Copy the zip to an external SD card and then insert the card to your phone (the easiest one) – Yey!.

Step 18 – In TWRP main menu, choose Install and then locate the no-verity-opt-encrypt-5.1.zip file.

p.s: The image is just illustration only and is as an example.

Step 19 – Flash the .zip file by doing “Flash to confirm flash” action. Swipe it to the right.

At this point, TWRP custom recovery is fully functional. You can either reboot into system or root, flash custom ROMs, or flash any custom binaries via TWRP like you want (e.g: custom mods like Viper, BEAT by Dr. Dre, Xposed Framework, etc).

Root Galaxy Note 8

Only proceed to the next steps if you want to root your device. Otherwise, you can simply stop at Step 19.

Step 20 – Transfer the downloaded SuperSU .zip file. It is strongly recommended to use its latest version available here. You can follow any methods in Step 17 above that really works for you.

Step 21 – Assuming you are still in TWRP (or otherwise reboot your phone into TWRP), tap on Install from the main menu.

Step 22 – Locate and select the copied SuperSU .zip file.

Step 23 – Install it by doing “Swipe to confirm flash” action in TWRP.

Step 24 – Sit tight and wait for TWRP to do its job. Once done, you will see the Success message being displayed.

Step 25 – Finally reboot your phone into system.

That’s all and congratulation! Your Galaxy Note 8 has been rooted successfully. You should find SuperSU app installed in your home screen. You can also download Root Checker app from Play Store to verify your root status.
