First of all everything has worked so far, TWRP 3.3.1.1 is installed with the patched ODIN, then I installed /e/ OS, Magisk and at the end the disable...zip.
What unfortunately happened since flashing TWRP: the display just goes off and can't be moved to turn on again.
At the beginning, pressing the power button several times was enough, now, in the middle of setting up the OS, it goes off, flashes only once in a while and I can no longer get into the system, can no longer perform any actions.
Can the flashe from the TWRP cause a graphics error???
Or is the refurbished phone simply out of order?

I want to root my Samsung S9+ (SM-G965F) phone whith a stock rom using TWRP and Magisk.
I am currently on Android 10 (Q) AP_G965FXXS

I've read lots of info from xda and internet, but the needed steps are not clear to me.

Can someone please confirm is TWRP/Magisk is possible on a Samsung S9+ and
what the versions of patches i should use ?

What Odin version should i use?
Several guides use version Odin3-v3.13.1.zip,
but latest i've found is Odin3-v3.14.4.zip ( Latest Stable version is Odin3-v3.14.1.zip )

I want to flash TWRP v3.60: twrp-3.6.0_9-1-star2lte.img

Is it neccesary to install the RTMM Bypass ? ( and ad what step in the procedure should i do this)
RMM_Bypass_v3_corsicanu.zip


Which no-verity showld i use ? ( there seem to be lot different versions )
no-verity-opt-encrypt-samsung-1.0.zip
no-verity-opt-encrypt-6.1.zip
Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip and rename it to: Disable_Dm-Verity_ForceEncrypt_quota.zip
Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip

How can i install Magisk ?
( S9/S9+ supported in Magisk v16.6 and above) :
Latest ZIP file in releases is: Magisk-v21.4.zip
Can i rename Magisk-v24.1.apk to Magisk-v24.1.zip and install this version
or should i install Magisk-v21.4.zip and upgrade to Magisk-v24.1.apk
( the files arm/magiskboot, arm/magiskinit and arm/magiskinit64 appear to be missing in v24.1 )

Should i install the OEM Root fix ? (and what is the purpose )
G965_PIE_Root_for_OEM_issue_devices_V5.zip
N965F_Root_for_OEM_issue_devices.zip

I successfully rooted s9 plus with android 10, latest security updates (may 2022) from this YouTube video:
It has the files in description for downloading.
In the video the only thing doesn't show (and probably needed?) is after flashing magisk, to flash DOWNLOAD DM-VERITY, FORCE ENCRYPTION, AND DISC QUOTA DISABLER. I used the newer one from the link here in 1st page, which is this: https://zackptg5.com/android.php#disverfe
Or you can go from the link in 1st page which will always have the newest.
Magisk version was old but updated it inside magisk app.

I need help
Whenever I tried to install G965 PIE Root on my Android 9 S9+, it freezes TWRP until I reboot it back to TWRP recovery. No Dr. Ketan logo shown, yet when I checked the bmp screenshoot on my internal storage from my PC, it does manage to boot up to magisk installer but it doesn't properly show on my S9+ screen. on Any solutions?

    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

    Nice.. you bringing a custom rom to S9+?
    Not decided yet. Never bought S series device since Note1. If I will buy S9+ then surely start development
    6
    V5 for Pie added
    ChangeLog :
    - Added support for S9+ (G965) PIE
    - Updated Magisk to latest stable V18
    - No more option for 'No root' as it won't serve any purpose and wrongly selected case it will cause bootloop.

    Yes the zip above works.

    As for root - a version of Magisk 16.3 also works. I do not have the zip, as I flashed Soldier's ROM that has it as an Aroma option. Also that rom, like the DevBase, lock the 3 troubling Samsung s__t also.

    I ended up installing Soldier's excellent stock+ ROM in the end.

    I appear to have been very lucky with my particular S9+. Installing it has been much easier than anticipated, given the reading I had done prior to the device's arrival 2 days ago.

    OEM Unlock was available as soon as I enabled Developer Options after unpacking the device and turning it on. I toggled it, accepted the factory reset, and when I booted into download mode, both OEM Lock and FRP Lock were off, and there was no mention of RMM. (I've noted this before, but I'm just recapping, because I can finish the whole installation story now).

    I then installed TWRP according to the procedure outlined in the device's TWRP thread, i.e. including the no DM verity/no encryption patch.

    Then, I spent a full day researching which root method to use, because there's currently a lot of contradictory information circulating regarding which methods work and which don't. For every possible combination of phone state + stock/custom firmware + stock/custom kernel + various ZIP files to be flashed to aid rooting, there are people who claim that this particular combination worked for them, and others who say that it didn't, and in many cases landed them (back) in frustrating 7 day lock status. Usually, rooting is quite trivial, but there are a million variables in the case of the S9+.

    I usually run stock ROMs on my Samsung devices, rooted with SuperSU, but there were just too many reports of SuperSU behaving very erratically. In addition, SuperSU development has stagnated since Chainfire retired from the project, so I was already pondering the wisdom of continuing to use it.

    In the end, Soldier's ROM seemed like the simplest solution. It's very close to stock, but has all of the anti-Samsung sanity preservation patches built in. I went with the custom kernel installation option, and rooted with Magisk this time instead of SuperSU.

    The device is now working like a charm. TWRP + root (inc. passing SafetyNet) + no waiting for OEM Unlock to appear. I can't believe the misery I've been spared, compared to some others.

    It's taken me 2 days to root it, because I've ploughed through close to 100 pages of XDA threads today. If I hadn't had to do that, I could have been rooted within an hour of opening the box.

    I just don't understand why there is so much variation in how these devices behave out of the box. Some people have OEM Lock straight away, but others must wait a week. Some people can toggle the setting without a factory reset, but others can't. Some people who perform that reset are then faced with prenormal RMM status, while others aren't.

    One thing that might be significant in my case is that I never logged into a single account on the phone until the device was running Soldier's ROM and fully rooted. Nor did I install a SIM card in the device. In fact, it has still never had a SIM card in the tray even now. I'll move my SIM card over from my S8+ tomorrow, once I've got the phone fully configured and all of my apps restored from back-up.

    Anyway, I just wanted to share a concrete story of how painless the installation of this particular device can be. I just hope that mine doesn't now start to exhibit random weirdness in the coming days.

    No mean to hurry but is there any ETA ?

    I uploaded V4 now which have option to flash RMM stat patched kernel for S9+ user
    Any S9+ users want to try this option, Download V4 (Link in OP) From TWRP flash V4 - select OEM patch + Select Patched kernel for S9+ + select magisk (must else device won't boot)

    Here some confusion there as there may not be OEM available because of kernel patch but should be safe to reboot. (No guarantee!)
