I have only tested this on my OnePlus8T Indian model - KB2001
Huge thanks to @topjohnwu for his magic.
YOU NEED TO UNLOCK YOUR BOOTLOADER!
In case you brick your device, use this unbrick guide
If you get into a boot-loop by flashing problematic magisk modules, consider using the patched recoveries from my post HERE to remove the modules.
Manual ROOT procedureSkip to step #6 and then #10 if you do not want to use the payload dumper tool and want to directly patch and flash the stock images for your variant and Build version!
- If you haven't updated OxygenOS yet, download it via the system updater. It will be stored in /sdcard/.Ota folder in your internal storage ( /sdcard/.Ota/OnePlus8TOxygen_15.I.16_OTA_0160_all_2010150110_84be0c.zip )
The size should be >2GB. If it is not, it's probably an incremental OTA, not a full one. This guide will NOT work on incremental OTA Zips.
DO NOT Reboot or else you will lose the file
- Copy the ZIP file over to your PC
- Download the Payload Dumper
Alt dumper for windows only:Extract the zip in the folder where you downloaded the payload dumper.
- Follow the instructions in the readme of payload dumper, and extract the OTA images:
You will get a boot.img file in the output folder.Code:python payload_dumper.py payload.bin
- Proceed with installing the OxygenOS update and reboot the phone.
- Download and install the latest magisk canary release to your phone : https://raw.githubusercontent.com/topjohnwu/magisk_files/canary/app-debug.apk
- Copy over the boot.img file created by payload_dumper to your internal storage
- Open Magisk Manager > Select Install > "Select and patch a file"
- Browse and select the boot.img file.
Magisk will create a patched boot.img file in /sdcard/Downloads/magisk_patched.img . Copy this file over to your PC. - Reboot to fastboot mode
Code:
adb reboot bootloader - Either flash the patched magisk_patched.img in the active slot or temporarily boot into it if you are skeptical.
I recommend to BOOT first and then perform a direct install via magisk as it is more reliable to patch the active slot.
To flash:
To Temporarily boot into a rooted system (RECOMMENDED!!):Code:fastboot flash boot magisk_patched.img
Code:fastboot boot magisk_patched.img
If you used the fastboot BOOT method, next you'll have to open magisk manager again, and this time, perform a "Direct Install".
This will install magisk on the active boot slot and the next reboot will give you root.
How to update OTA and KEEP ROOT
It is advised to disable all magisk modules to be safe!
For the curious / impatient, Here are the OTAs / boot images for the different 8T Versions
All patched images are removed to ensure users perform the steps 6 - 11 of the guide and also not trust images patched by others.
To find your model and build to download the right file:

KB2005 / KB05AA - International Variant
KB2007 / KB05CB - T-Mobile Variant
It's also a good practice to backup a few important partitions once you're rooted.
I used ADB shell, but you can use any terminal emulator from the play store (Termux)

cheers!3I'm posting here to detail how I solved an OTA update issue with my OnePlus 8T. For disclosure, I purchased this phone used, like new from someone who themselves got it open-box from a reputable retailer. So I don't know the full history of the phone, only that when I first booted it, it had clearly been factory reset and has been running flawlessly.
After I got the phone, I started looking into options for rooting. I unlocked the bootloader, and then, seeing that there was an OTA update for 11.0.9.9.KB05AA, prepared to try to root. I ultimately downloaded a Magisk-pre-patched boot image, thanks to Xi Jing Pooh (whoever you are), linked in these forum.
So after updated to the 11.0.9.9 OTA, I flashed that image, gained root, and again, didn't have any issues.
However, when the 11.0.10.10.KB05AA rolled out, I ran into problems. The OTA update kept failing with the message "Couldn't update, Installation problem."
I had prepared to update by following instructions on the forum; going into Magisk and restoring the stock boot image (an option when you choose "Uninstall Magisk"). I think it turned out I may flashed the pre-rooted boot image before ever booting into 11.0.9.9, so that might have been a problem. So I then used fastboot to flash the stock 11.0.9.9 boot image. I even did this to both a and b slots (maybe not necessary, I'm not sure).
While I did successfully unroot, my attempts to OTA update still kept failing. I then tried to manually update using a local copy of the OTA zip and got the same error.
After discussing with and getting good advice from @BillGoss and @g96818, I decided I would need to use the MSM tool to fully restore my phone to a previous OOS version and then incrementally update. @BillGoss also pointedly recommended I should do a full, manual update to 11.0 8.13 before letting OTA updates install, to ensure my file system had no inconsistencies.
Before I did this, I decided to try to capture a logcat while once again trying to manually update using my local zip of the 11.0.10.10 OTA. I started the update then immediately issued the logcat command in adb shell. As soon as the OTA install failed, I stopped logcat, then scrolled back to find the source of the error. Turned out that my dsp partition had been modified at some point and its SHA did not match that expected by the update.
@BillGoss pointed out to me later that 1) it's likely that the 11.0.9.9 OTA didn't touch the dsp partition, and that's why I had no problem with that update, and 2) I could have tried to dump the dsp parition from the full OTA for 11.0.8.13 and fix the issue without reverting to using the MSM tool.
But, I went ahead and followed detailed instructions to restore the phone to 11.0.7.9 (the latest MSM tool version). Per Bill's advice, after getting the phone setup again, I ignored prompts to download the OTA for 11.0.10.10 and manually ran the full OTA for 11.0.8.13. Finally, I OTA upgraded to 11.0.10.10, this time with no issues at all.
I forgot to unlock my bootloader during this process, so ended up doing that and setting up the phone twice. Then I rooted again, this time using the alpha TWRP that can be found here and installing the Magisk zip, which itself patches and installs the rooted boot image. This seems to have worked fine, and I've tested that I can also easily restore the stock boot before attempting to install the next OTA that comes out. - If you haven't updated OxygenOS yet, download it via the system updater. It will be stored in /sdcard/.Ota folder in your internal storage ( /sdcard/.Ota/OnePlus8TOxygen_15.I.16_OTA_0160_all_2010150110_84be0c.zip )
