How to root OxygenOS 12?

[andylmfao]

Hello there, I've never rooted a phone before but would love to try it with Android 12 finally coming out as stable on the OnePlus 8 Pro. So as a complete noob, can anyone walk me through it, or does anyone have a handy thread that takes me through all of it? Thank you!

Same method with OOS11 (other thread), u need full OTA OOS 12 to detached the boot.img and patch it with magisk.
- Or easier just on OOS11 rooted => update to OSS 12 (after install finished, dont reboot, go to magisk select install to inactive slot, now reboot)

As i know, there is still no downloadable full OTA file for stable OOS 12,
then root method is root at OOS 11 then update after.
to do that, imo, u need to find read and research some old thread to know about that phone before.
its easier than someone will write here for you.

Ah okay, thank you! Do you know how long it usually takes for an OTA file to come out? Or, if you could, help me through going back to OOS11, rooting it, and then updating to OOS12 and keeping root?

I guess you already setup adb/fastboot on your pc. If not google it.

-connect phone to the pc and activate usb debugging in your phones developer settings(unlock developer settings by tapping 5 times about phone)
-run a windows shell in the folder where you setup adb and fastboot.exe
-type the following in shell

adb reboot bootloader

Your phone will boot into the bootloader

type:

fastboot flash boot BootIMG-Magisk24.3_IN2025_11_C.11.img

And that's just it? Wow! Thank you!

Edit- It just say "Waiting for the device in the Shell. What do I do? And it doesn't show up with "fastboot devices" It also says there's no driver under windows device manager.

edit 2 - nvm I figured it out, turns out I hadn't installed the USB drivers

I hope it works for you now. Have fun.

Extracted from OnePlus8ProOxygen_11_C.16_15.E.16_OTA_1036_all_2204222258_57eced36 and patched with Magisk24.3.

I'm guessing that it's not a good idea to OTA root from oos11 to 12?

What do you mean? To preserve root with the inactive slot method within magisk?

I root my device with flashing a patched boot img.

Well that how yo'd normally do it, but for some reason when you do that on the OOS12 upgrade its get really weird.
