Magisk on Stock (rooted) Nougat?

Since going back to stock from the RR ROM, I've been using SuperSU 2.79 and really missing Magisk. Is it possible to use Magisk on the stock ROM, or is that only an option on LOS-based ROMs?

Yes, it is obviously an option. Simply download Magisk 14.0 zip, then go to SuperSU --> Full Unroot, then the phone will restart; after it does go to TWRP and flash Magisk

I haven't been able to uninstall supersu. Even after updating it to 2.82, it still says "uninstallation failed". Attempting to flash Magisk 14.0 fails also, as it detects an existing root method.

So install just boot.img from twrp and flash magisk.

Either do what WesTD says or find a SuperSU uninstaller zip (i think there's one around), or wipe system and reflash the ROM

I once did a full unroot of SU from a secondary ROM on my G3 and it wound up unrooting the phone itself. Bricked and out of service for some months (flashed so many ROMs it lost its LG identity so drivers never worked. Had to bring it back the hard way). Anyway...
What WesTD said is the easy way. Also the first time SU is flashed it saves the original boot image in the /data directory I believe with a gz extension (compressed). Gunzip it and you'll have your image you can flash.
Check the web for osm0sis' unSU script. It safely removes all of SU. For systemless you'll have to restore your boot image or dirty flash the ROM.
Ah, here we go...

Good stuff. Thank you!

I used Magisk for awhile on B19, but I've had too many issues with it, so I prefer Phh's Superuser. It's not nearly as well known, but it's fast, reliable, and works on the latest versions of Android (Oreo too). Basically it's the little guy that most don't know about or consider, they think Magisk and SuperSU are the only legit rooting games in town. I won't even give KingRoot/KingoRoot more than a mention, because they have ads and install crap, not to mention I've bricked a handful of low end phones by using these 2.
As far as ditching SuperSU (like if it's built into a rom, or you just want to switch, I use this order:
1. Flash osm0sis's unSU zip.
2. Extract your boot.img from whatever ROM zip you use, flash in TWRP
3. Flash Phh or Magisk zip and reboot
Reflashing system partition shouldn't be necessary, it's just the nuclear option of last resort that noone wants to do.

Could you say which problems you had with Magisk?
If you had f2fs then of course. But usually Magisk works as it should and has the module system which is very useful too.

Hi guys,
I have gone thru the forum to install Magisk systemless root in S7 Edge running 8.0 but have few questions.
1. Is TWRP mandatory to install Magisk for systemless root?
2. If above point is yes, then will the device be eligible for OTA even with TWRP recovery?
3. Please provide steps to install Magisk systemless root in S7 Edge running 8.0 latest October patch
Thanks in advance.

Thank you for your time and response. There is something called systemless root which will hide the root from the system and also allows official OTA updates.

From what I know, when you download an OTA and prompt your device to install it, your Android system performs a series of checksums to ensure that your /system, /boot, /recovery, and /vendor (or /OEM) partitions are unmodified from their original stock configuration.
The benefit of Magisk is that it does not modify the system partition, but while installing Magisk, the first thing it does is patch boot image. So you might have to restore the original boot image for the OTA to work.
Also, the OTA is designed to be installed via the stock recovery which has been overwritten with TWRP. So, I think u will face a problem there too.
I'm not saying that it's impossible to get an OTA update. It just might not be as easy as u r used to.

Got your point. Thank you. I read that Magisk can be installed without root or even custom recovery.
The below is taken from the official Magisk thread https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
How to download or extract the stock boot image file from my official ROM?
"Via Magisk Manager:
This method does not need root, and also does not require a custom recovery.
However, you MUST have a stock boot image dump beforehand, and you also have to be able to flash the patched boot image, either through fastboot/download mode or ODIN
Install the latest Magisk Manager
If you're planning to flash the patched boot image through ODIN, go to Settings > Update Settings > Patched Boot Output Format, and select .img.tar. For normal users leave it as the default .img
Press Install > Install > Patch Boot Image File, and select your stock boot image file
Magisk Manager will now patch your boot image, and store it in [Internal Storage]/Download/patched_boot.img[.tar]
Copy the patched boot image to your PC. If you can't find it via MTP, you can pull the file with ADB:
adb pull /sdcard/Download/patched_boot.img[.tar]
Flash the patched boot image to your device and reboot. Here is the command if using fastboot:
fastboot flash boot /path/to/patched_boot.img"

Just tried this method with local upgrade. It works indeed! Thanks!
But TWRP got lost from local upgrade. So after restarting flashed twrp-installer-fajita-3.2.3-37.zip via Magisk Manager. But install script anounced that I am now unrooted.
Restarting phone confirmed that.
Anyway installed root again via TWRP.

What is safe way to install TWRP in between those 5 update OTA+keep root steps? I once tried some kind of "OTA" update via twrp, but all was lost. (Could be a bit older twrp version without pattern unlock)

Why not just download the ZIP from the TWRP rather than use the OTA method?
The zips are available here.
I never uninstall magisk by the way. However that is part of the instructions. There are TWRP instructions, it's the third post, I believe.

Well I used this thread (How to Update/Return to Stock your OnePlus 6/6T(ROOT | NO ROOT | STOCK BASED |OTHERS)) from @mauronofrio as my guide. And in 2nd paragraph it states:
2. I have a stock rom with an unlocked bootloader and I'm rooted or I made some modifications:
You can use:
Local Update Method (Recommended)
Fastboot Update Method
TWRP Update Method
MSM Tool Restore Method
Local update method is recommended. So I was following this "general knowledge". Also I lost all user data (with nandroid backup) updating via twrp. Could be that my TWRP was outdated, but I would rather not to loose my user data again :/

Are you just OOS, rooted, TWRP?
I just flash the ZIP in twrp, flash twrp installer, reboot recovery, flash magisk. You can Repeat those steps if you want to update both slots. No reason to complicate it. I've never lost any data. The only time I format or lose data is going between OOS and AOSP roms. Then it is definitely important to backup data (always important to backup data anyways though).

Update system without computer and preserve TWRP?

Is there a way to update system to .14 and preserve TWRP?
I know that I can preserve Magisk, but I don't want to lose TWRP because I need to flash few more things.
Two more constraints:
I don't want to lose data
I don't have access to pc
In what steps I can achieve it, if any?

Yes, just go to TWRP with your OTA file, install the OTA file (in TWRP!), don't restart and install the ZIP file of the TWRP, reboot to recovery, flash magisk and reboot. Done. You'll still with your TWRP, rooted and updated.

Exactly. But make sure to only use the full OTA and not the incremental one.

Full guide
1. Go to TWRP
2. Flash FULL ROM
3. Flash TWRP INSTALLER (if u fail to u will lose TWRP)
4. Reboot your device. (yes boot it...and access your phone)
5. Reboot back to TWRP
6. Flash Magisk
Working method...tried nd tested 50+ times

The following also works. Follow it precisely.
> Install the update through the OS Update UI.
> Open Magisk Manager and find the module that preserves TWRP. Flash it. It won't appear in the module list. Don't restart yet, you'll lose Magisk if you do.
> Open Magist Manager and click "install". Install to inactive slot (OTA)
> Reboot!
Done this a few times now, it's actually more convenient than booting to TWRP.

I use always that way. The module is called TWRP_A_B_Retention_Script-Magisk.zip.

Open Magisk Manager > Downloads and it's called : TWRP A/B Retention Script.
To find it easy order by name. Default it's by last update.

[GUIDE] Root OOS with TWRP

Update 220823: Update for TWRP 12 and some other minor changes due to the switch from SafetyNet API to Play Integrity API
Updated 211203: include Magisk Canary
Edited 220113: correct a mistake in the Keeping Root process; some formatting changes
I keep seeing posts that say you can't root OOS after an OTA unless you have a full image installation zip. That's just not true these days (September 2021).
You can use @osm0sis' method in https://forum.xda-developers.com/t/...ices-platforms.2239421/page-149#post-84764713
And @g96818 suggests using "Install to inactive slot" which works provided you do it properly - see https://forum.xda-developers.com/t/...00-kb2001-kb2003-kb2005.4178675/post-85801253.
And here's how to do it using TWRP.
What you'll need:
OOS 11: TWRP image (.img) and (optionally) installer zip from https://forum.xda-developers.com/t/recovery-11-alpha-teamwin-recovery-project-8t-kebab.4302449
OOS 12: TWRP image (.img) and (optionally) installer zip from https://forum.xda-developers.com/t/...win-recovery-project-8t-9r-2022-07-27.4473983
Magisk apk - using stable from https://github.com/topjohnwu/Magisk/releases or using Canary from https://github.com/topjohnwu/magisk-files/tree/canary
Universal SafetyNet Fix (UNSF-MOD) by @Displax from https://github.com/Displax/safetynet-fix/tree/integrity
I'm also assuming you have an unlocked bootloader, know how to use fastboot, how to use TWRP, and how to use Magisk.
I'll go through rooting a currently unrooted version of OOS and then doing an incremental update OTA.
Root unrooted OOS
Install the Magisk APK. I find that this works nicer than letting the stub download the full app the first time you use it.
Boot into bootloader mode.
Boot TWRP using fastboot boot x.img where x.img is the TWRP image file.
Take a backup of the current boot and recovery partitions as you'll need them for successfully updating when the next incremental OTA becomes available.
Install the Magisk APK, just like you would install any zip file in TWRP. Note: the APK must be named Magisk-*.apk otherwise TWRP won't list it. Also install USNF if you are using Magisk Canary.
If you want to keep TWRP then install the TWRP installer zip.
Reboot.
If you are using Magisk Canary, in Magisk>Settings enable Zygisk, Enforce DenyList, and Configure DenyList. Then reboot.
Keeping Root on an incremental OTA update
Note: you do NOT need to (but can if you want to) follow this process if you're installing a full OTA. You only need to install the full OTA and then install Magisk to the inactive slot and reboot from Magisk when it prompts you.
If your phone tells you you have an update:
If you have TWRP installed, then boot into TWRP and restore the stock recovery and reboot.
In Magisk tap on "Uninstall Magisk" and select "Restore images".
Install the OTA update but don't reboot yet.
Turn on airplane mode so that apps can't call SafetyNet when you reboot the phone without root.
Reboot
When the phone has successfully rebooted the updated system, boot into bootloader mode.
Boot TWRP using fastboot boot x.img where x.img is the TWRP image file.
Take a backup of the current recovery partition as you'll need it for successfully updating when the next incremental OTA becomes available.
Install the Magisk APK, just like you would any zip file in TWRP. Note: the APK file name must start with Magisk- otherwise TWRP won't list it. Your existing Magisk settings, modules, and [hidden] Magisk app will be preserved.
If you want to keep TWRP then flash the TWRP installer zip.
Reboot and disable airplane mode.

You have a number of options:
If your update was an incremental OTA:
1. Ask in the Q&A forum or in one of the update threads if someone can share those two partitions with you.
2. If you're on 11.0.10.10kb05aa then you can get boot from a number of the update/rooting threads and the recovery from this thread by @mslezak https://forum.xda-developers.com/t/...-rooted-users-install-from-fastbootd.4316147/
3. Use this tool by @mslezak to create the full partitions from an incremental update https://forum.xda-developers.com/t/...urrently-op8t-11-0-9-9-kb05aa-posted.4314677/
If you updated using a full installation zip:
- use payload dumper to extract the two partitions from payload.bin

I'm Magisk rooted and I have TWRP installed on my 8T EU model.
The OnePlus updater app registers that I am rooted and wants to download the full OTA.
Do I also have to do all the things you described after "Keeping Root on an OTA update" or is there a simpler way?
If yes, then I have a question regarding this step:
2. In Magisk tap on "Uninstall Magisk" and select "restore images".
Click to expand...
Click to collapse
Did Magisk automatically backup these images? Because I didn't do it myself. I only have backed up all my partitions (including boot) after I had installed TWRP and before I rooted.
EDIT:
BillGoss has thankfully already replied in another thread (in which I have basically asked the same question because I am an impatient bast***) where I suggested the overly present "easy" update scheme, which he expects to work. So this should be fine for other people in my situation:
1. Let the system download and install full OTA and DO NOT let the device reboot after it's done
2. Install TWRP A/B Retention Script
3. Install Magisk to inactive slot and reboot
EDIT2:
I just want to add that before having done the above mentioned steps 1-3, I have disabled all Magisk modules and rebooted the device. So the full procedure is the following:
1. Disable all Magisk modules and reboot
2. Let the system download and install full OTA and DO NOT let the device reboot after it's done
3. Install TWRP A/B Retention Script
4. Install Magisk to inactive slot and reboot
Youtube step by step video (he says that he "uninstalls" the Magisk modules but he just deactivates them):

Thanks @haitower
I've updated the OP to make it clear that the process described there only applies to incremental updates.
Also, to answer your question re Magisk backups: Magisk writes a copy of the installed boot image to /data/Magisk* before patching it. A "restore image" uses that backup.

9. Clean up old Magisk backup copies of stock boot images by using File Manager to delete /data/magisk_backup_* directories
10. Install the Magisk APK, just like you would any zip file in TWRP. Note: the APK file name must start with Magisk- otherwise TWRP won't list it. Your existing Magisk settings, modules, and [hidden] Magisk app will be preserved.
11. If you want to keep TWRP then flash the TWRP installer zip.
12. Reboot and disable airplane mode

Hello,
Thank You for the detailed description, it helped me a lot.
I'm new with the Oneplus 8T phone. The last handset I had was the Mi MIX 2. The rules of using root are familiar to me and I understand everything from your description. I only have a question about TWRP, once I have them permanently installed on device, can I backup the system or date partition via TWRP? I always made backups in case i messed up something and didn't work properly.
This question came from https://twrp.me/oneplus/oneplus8t.html
They write there:
"This device uses Dynamic Partitions
This means that TWRP will not allow modifications to any of the partitions that make up the Super partition on the stock ROM. All backups and restores will include the full Super partition rather than the individual dynamic partitions.
In order to flash the individual partitions, you will have to boot into fastbootd."
I would be grateful for Your information, Thank You.

Hello!
Today I saw that EU: 11.0.12.12.KB05BA was available as OTA Update so I started to download it using the "Keep root on OTA Update".
During the download I recognized that I was still only connected to mobile network 4G instead of WiFi.
So I stopped the download of the OTA, restarted the phone and turned on WiFi but now I don't get the notification for the new OTA Update anymore and when checking for new Updates it says that my OOS 11.0.11.11 is up to date.
I guess the system has somewhere already stored that I started the download of the new 11.0.12.12 OTA but did not finish it and now I don't get the message to download it anymore.
Any idea how I can fix this so that I can download the new OTA again?
Thanks a lot!
EDIT: I am downloading it now via OxygenOS Updater (the full OTA).

I understand that if I want to restore system and data when something doesn't work for me then I just do recovery for all the partitions, system, data etc that I do in twrp?

Please see the update in the OP regarding OOS 12.
