DISCLAIMER
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 procedure
Skip 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:
Bash:
adb shell getprop ro.product.model
KB2001
adb shell getprop ro.build.version.ota
OnePlus8TOxygen_15.I.16_GLO_0160_2010150110
adb shell getprop ro.build.display.id
KB2001_15_201015KB2001 / KB05DA - Indian Variant
KB2003 / KB05BA - EU Variant
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)
