[08.01.19][Guide] ROOT S9+(Exynos)Magisk + OEM fix + EFS Backup Tool

[dr.ketan]

Here is script for Root + OEM Fix for S9+

READ THIS BEFORE ROOTING DEVICE

- Any of below said method to root will trip knox and void warranty forever.
- Root process needs wipe data so make backup of important data (including Internal Device storage) before proceed.
- 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.

What is OEM fix?

Since Note8 samsung have introduced OEM unlock control remotely and flashing any custom binary removes OEM unlock option and rebooting in this state it ends with custom binary error and have to flash stock firmware. OEM patch will retain OEM unlock option in spite of having custom recovery. If you are not sure your device have OEM issue then there is nothing wrong to use 'OEM patch' option.

If you don't have OEM unlock option out of box then it may appear after 7 days, before this nothing can be done. Also this suggest, you have OEM affected device.

How to Root device

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 G96*_Root_for_OEM_issue_devices_V*.zip to Ext SD card (There is different files for Oreo & Pie according device)
4.Download TWRP for S9+
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

14A (If you are ion Pie).
Now select Install and navigate path to Ext SD card - N965F_root_OEM_issue_devices.zip, you have copied earlier, select desired root method and select 'OEM Patch' option if your device have OEM issue. If you are not sure about this then better select 'OEM Patch', this will prevent losing OEM unlock option and so prevent 'custom binary error'
OR
14B (If you are on Q)

Flash Latest magisk & then DM-VERITY, FORCED ENCRYPTION, AND DISC QUOTA DISABLER


15.Once flash successfully finish, Reboot to System


Important Note for Pie OS -
1.You may find OEM option disabled after root by above method, Even if you enable and reboot, again it will be disabled. This is because of kernel is patched while rooting device to prevent binary errors. So ignore this OEM status as it is.
2.Magisk app may not be there in drawer. Simply Download Magisk app for Pie attached here and Install as regular apk.


Root device with Q

Flash Latest magisk & then DM-VERITY, FORCED ENCRYPTION, AND DISC QUOTA DISABLER

Not decided yet. Never bought S series device since Note1. If I will buy S9+ then surely start development

Great.. I've setup the whole device but it still feels incomplete with proper root and a custom ROM

What do you think about flashing treble aosp

 

[whc.faith]

EDIT: sorry, just realized i posted in the wrong thread.

 

[dr.ketan]

so i tried the method above and got the RED "only official released binaries are allowed to be flashed"
phone wont boot up... any support is appreciated.

I also tried to resinstall TWRP through ODIN and it keeps failing.

Have you selected oem patch option in aroma?

apologies, i just realised i posted in the wrong thread, this was supposed to be a response in the official TWRP root thread.

Am waiting for magisk to be fixed and then I'm all Root

Does one needs to format data during the process?

Without full format device storage won't be usable bcoz of encryption.

Same here. Magisk seems to work very well. I tried using supersu and suhide, but it wasn't passing. I need to be able to hide root, and Magisk does a great job at it.

Oh wow i haven't seen you since the note 2 days as I skipped upgrading Note series as well as S series. Good to have you here

 

[codekaran]

Has anyone tried this root method? Does it work perfectly without boot loop or bricking the phone?

 

[d1nd141]

This works fine here with supersu on G965f/D.

 

[codekaran]

Tried this method. Was able to flash recovery successfully and install the zip but after clicking reboot to system, it won't boot the phone

Have you selected supersu and oem patch option both?
