Please help 🥺
Please read and use the official update thread for any update related discussion
Instructions on how to report bugs and leave feedback are on the first post.
In future, please use the search function and discuss in the existing threads instead of creating a new thread. Follow the forum rules.
Rollback instructions are here.
Sure that your issues can't be solved better with a factory reset and clean setup? Rolling back wipes your phone anyway.
Hi can anyone help a oneplus 8 pro user here.
My model is IN2020
Currently running oxygen os beta 12 and the battery drain is too much
How do i downgrade to oxygen 11?
Don't know where you got that beta 12 from, maybe they site where you got it from can tell you.
As far as I know no official open beta has been released by OnePlus and should you have joined closed beta, well the forums isn't the place to be.
I purchase this phone from a secondhand shop. And this is the CN version but I live in Malaysia. I have search everywhere but couldn't find the solutions. please help me
Without a downgrade zip you need the MSM-tool for your phone. But since it's a Chinese version it may be trickier.
What is MSM tools? Can you guide me? I think eventho its chinese version its flashed with global rom
Just to be clear here, are you on open beta 12 based on Oxygen OS 11 or on a beta of OxygenOS 12? What version do you exactly have?
I'm on android 11,
The build no is OP8Pr2_Beta_12
Ah, in that case you can follow the instructions and use the rollback links from the last open beta thread here to switch to the stable channel
Or download the latest full stable update from an external source, and try installing that over your beta version via local upgrade.
But back up all your data first because both ways will wipe the data from the phone
So since i'm using the CN variant, i shall download the global or EU file am i right?
I think global since you're living in Malaysia. But to be sure you could wait to see what @Swejuggalo knows about that when he sees your messages here.
I downloaded the file but still couldnt see in the local package update from the setting
Solved. From your link i scroll all the way to XDA they mention to download oneplus updater. Now im back at oxygen os 11. THANK YOU
Ah, great. You're welcome 👍
But the battery drain is quite noticeable. Any idea on saving more juice?
For now this is normal since you've only did an update just now. Allow the system some time and some full charging cycles to let it optimize itself and observe how it behaves after that. There are a couple of useful battery threads out there as well, for now i'll link just the one that explains things pretty well.
Thanks! Will take a read once im home. Anyway do you root your device? If so can you share the most complete procedure if any? Last time i root an android was during gingerbread os
You're welcome 👍
No, That's something i don't have any experience with, sorry. But i suspect the user i tagged in one of my comments above does and maybe he will be able to help you with that
[GLOBAL] APPLY NOW! OnePlus' FUT Program is back (again)!
