[Guide] How to Root Note8 + EFS Backup

Quote:

READ THIS BEFORE ROOTING DEVICE

- Any of below said method to root will trip knox and void warranty forever.
- As of now you will lose Samsung Pay and Secure folder forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device). Also you may not able to run some banking apps, but for that there are some workaround like Magisk Hide or SU hide, google it.
- OTA likely won't work once you root device.
- To unroot device completely, simply flash Samsung stock firmware, Remember, Unrooting won't revokes warranty nor you will be able to use Secure folder/Samsung Pay. Once rooted, these feature gone for you unless some magic happen in future and may find a way to use it.



Here is detailed guide about Root Galaxy Note8. Guide made in two sections, One who want root + Custom recovery and second Root without flashing custom recovery.


Quote:

1.Root with TWRP (Recommended method) You can root with SuperSU OR Magisk

Root with TWRP is preferred method as it gives option to flash zip like mods,custom ROMs etc

Root with SuperSU

1.Enable Developer Option (settings - about phone - Software information - Tap 7 times on build number to activate developer option in settings menu)
2.Enable OEM Unlock from developer option (Currently no workaround for those who doesn't have this option)
3.Download SuperSU (I have used SuperSU 2.82 SR4) to Ext SD card. Here is Original thread to see if any update available.
4.Download TWRP for N8
5.Switch Off device
6.Press Vol down + Bixby + Power to reboot to download mode, press volume up when asked to continue to download mode
7.Download Odin and open it, Disable 'Auto reboot' from option menu of Odin
8.Select TWRP (tar image) with AP tab of Odin and Start
9.Once Successfully flashed, you will see 'Passed' in Odin tab
10.Disconnect device and hold Vol down + power till screen goes off, Now immediately press Vol Up + Bixby + Power to reboot to TWRP
11.Select to allow modification
12.From TWRP, Select WIPE menu - Then FORMAT DATA - You need to type 'yes' to perform wipe. WARNING : This will erase all data including Int SD storage from device
13.Once format device completes, go back and select REBOOT' Menu and then - 'RECOVERY', This will reboot to TWRP again
14.Now select Install and navigate path to Ext SD card - SuperSU, you have copied earlier
15.Once SuperSu flash successfully, Reboot to System

Keep patience and allow device to boot, It may take time as we have formated data.

Once device boot, you will have SuperSU in app drwer with working boot.

---------------------------------------------------------------------------------------------------------------------

Root with Magisks


1.Enable Developer Option (settings - about phone - Software information - Tap 7 times on build number to activate developer option in settings menu)
2.Enable OEM Unlock from developer option (Currently no workaround for those who doesn't have this option)
3.Download and copy latest Magisks zip to Ext SD card
4.Download TWRP for N8
5.Switch Off device
6.Press Vol down + Bixby + Power to reboot to download mode, press volume up when asked to continue to download mode
7.Download Odin and open it, Disable 'Auto reboot' from option menu of Odin
8.Select TWRP (tar image) with AP tab of Odin and Start

10.Disconnect device and hold Vol down + power till screen goes off, Now immediately press Vol Up + Bixby + Power to reboot to TWRP
11.Select to allow modification

2. Root with Stock Recovery
This will give just root access and No custom recovery. (you can't flash custom ROM, mods zip with stock recovery but still can use FlashFire or similar.
1.You need to have stock firmware, Extract boot.img file from that firmware with winzip or similar
2.Install Latest Magisk Manager
3.Open it and explore settings - Patched Boot Output format - select img.tar
4.Now again from main page of Magisk Manager click Install - Install - Patch Boot Image File and patched the boot.img
5.Copy patched_boot.img.tar to a PC from MagiskManager directory on Int Storage
6.Enable Developer Option (settings - about phone - Software information - Tap 7 times on build number to activate developer option in settings menu)
7.Enable OEM Unlock from developer option (Currently no workaround for those who doesn't have this option)
8.Switch Off device
6.Press Vol down + Bixby + Power to reboot to download mode, press volume up when asked to continue to download mode
7.Download Odin and open it, Disable 'Auto reboot' from option menu of Odin and
8.Select patched_image.tar (You copied as step 5 above) with AP tab of Odin and Start
9.Once Successfully flashed, you will see 'Passed' in Odin tab
10.The phone restarts and ask to reset to factory settings, This will erase all data from device
11. Let reboot device and install Magisk manager again and open it. Now you will have root.
12.You can install FlashFire and re flash Magisk zip again to have magisk module to work.

EFS Backup : Will provide Tool shortly

How one can flash ROM without custom recovery? Also to use FlashFire or similar, you need a rooted device. There is nothing can be done before this option (OEM Unlock toggle) appear, or at least something can be done to make appear this option, it must be through odin by faking samsung binary.
