Is it possible to root OOS 10.0.1?

lately I did a clean install of OOS 10.0.1 on my International 6t. Installed OOS and magisk from TWRP.
After booting there was a Magisk Manager in applications claiming that Magisk itself was not installed. I tried to install Magisk from Manager, but failed. Then I reboot the phone into the recovery and TWRP was gone!! There was only a stock recovery. Well, I tried to run TWRP from computer with 'fastboot boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img'. Error - "remote: unknown command".
I searched forum and found a thread fastboot boot twrp.img FAILED (remote: unknown command). @dbarrett480 wrote: 'Twrp can't flash anything to system in A10 right now, so unless that is fixed there is no point at this moment anyway. A10 uses a virtualized system partition which doesn't allow R/W access to system....'. Does it mean that rooting is not possible with stock OOS and only possible solution is to use custom ROM?

It is. Look for the patched boot.img and flash that through fastboot. Make sure to install magisk manager first.

The information you found is outdated. I'm surprised you didn't properly read through the official TWRP thread here, more specifically this post clarifies the error in your use of fastboot (or better said: the use of fastboot according to the mistakes made by OnePlus). Which is also mentioned several times in the page you linked to.
As a senior member, please don't create new threads inquiring information you could easily find. Even though the methods to obtain it have been challenging for a short while, being able to achieve root has never been interrupted for this device. Even without being able to modify system files. Systemless rules!

So, should do following:
Install Magisk Manager
Flash patched boot.img through fastboot
Install TWRP
Install Magisk
Is it correct?

The patched boot.img already contains magisk.
But you don't need twrp to be rooted, unless you really want to use it for something else... But i don't use it anymore. So I'm fully stock, except that I'm unlocked and rooted.
So it should be:
1. Install magisk manager.
2. Flash boot.img
3. Enjoy. But check magisk manager if it was successful.

Regarding all that was said here, is rooting possible by following these steps?
Reboot
Fastboot TWRP img
Use volume up to recovery and power button to boot to recovery
Flash 10.0.1 stock boot img from TWRP
Flash TWRP zip
Reboot to recovery
Flash Magisk 20.1
Flash kernel if want
Reboot system

That's only if you need TWRP.
But for what I've been reading, you don't need TWRP and then i suggest to not install it.
Just flash everything stock and keep it that way. Only thing to flash is the patched boot.img with root in it.
You can always update Android from the settings and patch/install boot with magisk manager on inactive slot. This will keep your device rooted without the need of TWRP.

Here what I found:
https://forum.xda-developers.com/showpost.php?p=81111389&postcount=145
Today I installed the new update, 10.0.1 for OP 6T and then I discovered that there is no magisk patched boot.img yet. I extracted it with payload dumper, patched with the installed magisk and flashed successfully.
I uploaded it to my drive for others. https://drive.google.com/open?id=1kb...VgWNaWgLN6j17b
The commands for flashing are:
fastboot flash boot_a magisk_patched.img
fastboot flash boot_b magisk_patched.img
Maybe someone can add it to the first post.

I still don't get why people don't use the good old way:
fastboot flash boot twrp.img (latest version)
If you just need root use twrp to flash Magisk zip
If you need twrp flash twrp installer also
Reboot
All the mess before was because we didn't have a working TWRP! Now that we have it don't need to use patched boot img made by others.

Coming from a custom ROM (PE 10), is it possible to flash the stock 10 using fastboot, or this will cause issues?

Without TRWP installer. I reboot to bootloader after every single step and boot TWRP.img manually with fastboot boot TWRP.img
So stock recovery is preset
Step by step:
- Boot twrp.img in fastboot from PC "fastboot boot twrp.img"
- Delete all partitions and be sure active boot slot is "A"
- Reboot to Bootloader, NOT Recovery
- Boot twrp.img in fastboot from PC "fastboot boot twrp.img" again
- Install Android 10 zip
- Change active boot slot to "B"
- Reboot to Bootloader, NOT Recovery again
- Boot twrp.img in fastboot from PC "fastboot boot twrp.img" again
- Flash Encryption Disabler zip
- Flash Magisk zip in order
- Reboot! Profit!

Hi, very helpful guide.
But how do you get OTA update when there's a new one? Can you provide the steps to get OTA and then get back to root. Thanks in advance.

Just install normally via updater.
But before you restart your phone, install TWRP Retention Script via Magisk Manager to change active boot slot

Magisk W/ Android 11 on OnePlus 8 Pro

Hello all...
Just a quick question as I am reading and seeing so many different answers. I have the UNLOCKED US version OnePlus 8 Pro (IN2025) Which is currently running Oxygen OS 11.IN11AA (Android 11 Official). I have successfully unlocked the bootloader and am ready to root with Magisk. I am at a loss because I dont know which Magisk to use or how to properly flash it. I have Magisk Manager 8.0.2 and have Magisk version 21.0
I have also downloaded the patched boot image from here... https://forum.xda-developers.com/oneplus-8-pro/how-to/root-patched-boot-img-android-11-op8-t4174919
What am I doing wrong? Can someone please just give me a quick rundown... I am not new to rooting just haven't done in in over a year. Thank you!

Don't think your doing anything wrong, just need to get that image on your pc, and fastboot flash it to both a/b slots then reboot your phone and you should have root available
adb reboot bootloader
fastboot boot (name of image).img - Try this one first as it just allows you to see if the phone boots up fine, if it does reboot back into the bootloader and then do the following...
fastboot flash boot_a (name of image).img
fastboot flash boot_b (name of image).img
fastboot reboot

How do I get Magisk 21.0 to install through Magisk Manager?

You don't, that's why you've downloaded a patched img, that has been patched with magisk already, just need to flash it accordingly

This is what I am getting after following your directions to a T!
I also flashed to both partitions. Please see attachments. I sent 2 screenshots.

You don't do the install from magisk, have to copy the patched img to a pc where you have adb/fastboot installed then install from command prompt

I did not do the install through Magisk Manager I did the install via adb and fastboot in fastboot mode. It Said flash successful. But when I go into Magisk Manager after rebooting, nothing changes.

Doesn't work. Download the patched image, put it on the phone, use magisk canary manager to patch it again, transfer it off your phone, then boot into Fastboot and flash it.
It has to be patched in the phone it will be installed to otherwise it will not work.

Use the beta magisk.
Re-patch it in your newly updated magisk manager then flash to both slots..
Also verify the size of the file prior to flashing.. Mine was 96MB

Here is the exact size.

I am a little confused now... I uninstalled root for a few days and now have the second release of android 11... I am in fastboot mode doing fastboot flash boot... then the file name and all it says is waiting for device?? Any help??

What is the explanation as to why one needs to fastboot flash Magisk to both slots instead of using the following command:
adb reboot bootloader
fastboot getvar current-slot
*in my case Slot B*
fastboot flash boot_b magisk_patched.img
fastboot reboot

You can, however flashing to both slots is seemingly easier.
Personally I wouldn't flash at all.
Just boot to avoid the possibility of a bad boot.

It's preferable.
There are some things to note.
1st. You are only booting it, meaning if you reboot; you will start using the installed / flashed image and the booted image will be lost.
2nd. For the above reason. If you want to make root permanent you have to open magisk after opening and then click install - install directly.
As magisk will already have root access, it will be able to accomplish patching, if you tried this whilst unrooted it would fail, or not be an option.
3rd. By booting you avoid the potential bootloop problems you can and almost will have at some point if you always flash, bad images are pretty rife for a number of reasons.
I've got a large guide for rooting in the guides section which covers all the bases and their shortcomings /benefits.

Failed Update from 10.3.12 to 11 - Assistance Appreciated

Attempted to update from the latest stable 10.3.12 to 11 by flashing the full OTA zip in TWRP.

I can get to Fastboot, but I'm not sure if I should try flashing twrp.img or pull boot.img from the OTA or what.
Anyone have any suggestions?

Flash temporary recovery first ( lineage recovery ) then from fastboot.. boot into recovery.
You will see lineage recovery.
Select apply update - > update from adb ....
Then "adb sideload <twrp image>.img...
(probably it ask to verify choose yes)
Go back select advanced restart ( not sure the right word ) -> reboot to recovery.
Then you will have twrp installed.
If you only want to root why not flash magiskpatched image there no need TWRP just to root.

Hm but how would I install lineage recovery? Flashing recovery through fastboot doesn't work on the new devices anymore right?
I also tried booting lineage recovery without flashing but that also didn't work (although it didn't get stuck on crashdump but booted into the regular OS instead).
I did notice that it seems to be related to OOS 11 firmware. On 10 booting into TWRP works just fine and as soon as I upgrade to 11 it stops working (maybe this means it's fixable?). What I used as a workaround for now is to have 10 firmware in one slot, upgrade other slot to 11 and flash TWRP to both slots from the 10 slot. Seems to work so far but is not ideal IMO. I'm not a developer sadly but maybe someone smarter than me will come up with a solution.

What do you mean by "new device"?? New OOS version right??
I use this method all the time with oos 11.x.x.x.x to install TWRP so i can install Custom ROM later.
no need to go to oos 10 you can flash it from newest oos11.
---------------------------------------------------------------------------------------------------------------
First boot into fastboot mode.
to install lineage recovery
fastboot flash boot <lineage recovery image>.img
download from here https://download.lineageos.org/fajita
menualy select and boot to recovery. It will boot to lineage recovery.

lmao it appear in two posts. deleted 1.

About to give up on flashing recovery to OOS 11.1.1.1

I tried "fastboot boot" almost all of KizuYuna's .imgs, tried fastboot boot the lineagerecovery.img. All I get is the fastboot logo and the phone just restarts into OOS... TWRP is same.
About to MSM downgrade to OOS 10 to get recovery working like I did before. Thought it would be better to flash a rom from OOS 11 to get better firmware compatibility but just wont work.

Simply go back to OS 10.3.5 using the MSM Download Tool. Upgrade via OTA to 11..1.1.1, fastboot flash boot magisk_patched-23000_11.1.1.1 from XDA 235Sanders15 post. (you are now rooted with Magisk.

So you are saying MSM to 10 and then flash official 11.1.1.1 or fastboot flash boot magisk_patched-23000_11.1.1.1 (this is a full 11.1.11.1 OS flash? No need to use twrp from 10?)
Thanks

So I just went thru an Android 10 to 11.1.1.1 upgrade, and it was a bit frustrating. So I'll throw out what I learned along the way.
Note, I have a T-Mobile Variant, so sometimes you need different files/steps for T-Mo.
I flashed the full OTA via Settings > Update > Local Upgrade, which ended up boot-looping.
Via Fastboot, I did fastboot flash boot magisk_patched-23000_11.1.1.1.img; followed by fastboot reboot;
This was still boot-looping, so I shutdown the phone, and booted into recovery, which was now PBRP.
via PBRP, I flashed the full OTA again from my SDCard; then installed PBRP zip;
Reboot to System and got a Successful Boot. Yey.
Reboot to Recovery; Backup Boot.
Reboot to System
Install Magisk App; within Magisk > Install > select my Boot Backup to Patch (per Magisk instructions); I used a file manager to copy to my PC from my phone
Reboot to Fastboot; fastboot flash boot magisk_patched-23000_rJoA.img (the file Magisk created)
Reboot to System; Success!
I guess my morale of the story is, get a clean boot working, go from there. Patch your own boot, don't rely on someone else's.

So you had to go through all the trouble because you had a bootloop issue when OTA updating to 11? I already got to 11 but am trying to fastboot boot a recovery because I want to flash a custom ROM... When I fastboot boot TWRP.img or LOS Recovery .img it just shows fastboot logo and restarts the phone with no recovery shown..
