Install TWRP and Root Samsung Galaxy Note 8 (Exynos)

Samsung Galaxy Note 8 is the latest and the last addition to Samsung’s flagship lineup for 2017. As is the case with Samsung flagships, there is a Snapdragon variant of the Galaxy Note 8 for the US, China, Japan, and Hong Kong. The rest of the world is sold the Exynos variant. Naturally, the Exynos variant then tends to receive a lot of developer love from developers all around the world. And this stays true with the Exynos variants of the Galaxy Note 8 which can now be equipped with an unofficial TWRP build. All thanks to XDA member geiti94. Consequently, users can also root the Galaxy Note 8.

Requirements

The guide below works for any Galaxy Note 8 device as far as the SoC powering it is an Exynos chip (N950F/FD/X/N). But before you can install TWRP and reap the benefits, you’ll have to make sure your device checks the following boxes.

• Your Galaxy Note 8 should have an unlocked bootloader.
• Make sure the device has at least 50% battery remaining before you begin the process.
• You must already have Samsung’s latest USB Drivers installed on your PC.
• Also, ensure that OEM Unlock and USB debugging have been enabled on your device. You can find both the options in Settings > Developer options. Developer options can be enabled by going to Settings > About phone and tapping on the Build number several times.
• While using Odin3, disable Samsung Kies if you have it installed on your PC.
• It would be wise to back up all your important data just in case.

Note

Okay, so you’re ready to install a custom recovery on your device and possibly root it too. But there are some things that you should consider before you move ahead.

• When you flash a custom recovery like TWRP, KNOX will be tripped. Meaning unless your country forces Samsung to provide warranty regardless of the software status, your warranty is void.
• You will no longer be able to install OTA updates from Samsung and that includes the Android 8.0 Oreo update Samsung has promised.
• The unofficial TWRP is not exactly bug-free. Although it does work well in most cases there is some room for improvement.

Also, make sure that in the rare case that things go south, you own up to the responsibility. DroidViews is not responsible for anything that might or might not happen to your device while following the guide. That said, the method described below has been tested by users and has been found to work.
