Hi guys!
Just today, I updated my 7T [EU model] to the new, stable version of OxygenOS running on Android 12. However, I quickly realized that I much more prefer the old stable OxygenOS 11. Is there a way to downgrade to that version? I've tried scouting online, however, I only found downgrade links to Indian models.
Thanks very much!
Hi my friend!
Just check the official Oneplus forum (oneplus.net). There is a post OxygenOS 12 MP2 for Oneplus 7T/7TPRO that is pinned. There is a download link for all versions. Note that your cell phone will be erased!

Thanks a lot, worked 100%
I just upgraded from 11 to 12, and i loose my connection every hour. Only thing that can bring back my signal is switch the phone into flightmode and back.
So will revert back to 11 as you did.
One questoin did the roll back wipe the phone or was apps and other settings still on the phone?

Is it possible to keep root through the rollback if I patch the boot image with Magisk before rebooting?
Edit: Just downgraded and had to root again after the downgrade (patched boot.img)
I am in the same situation. Upgraded to Android 12 and I'm having so many problems. I too am now downgrading. And actually moving away from OnePlus. Too many problems. Gonna try Carl's Nothing phone.
Hey there, Is it the original thread on offi OP site is not available anymore.
Do You guys remember the steps and what was needed to do the downgrade by chance ?
Help appreciated.

Hi guys,
I installed Android 10 via OTA but it is full of bugs. I want to go back at 9 which was perfectly stable.
Is there a way to downgrade from 10 to 9 without losing the European warranty?
Thanks :highfive:
I haven't tried this, but downloading the previous full system zip from ASUS and using adb sideload from ASUS' recovery should work in this way, I could be wrong.
Edit, I tried this ^^
Didn't work, perhaps follow this guide: https://forum.xda-developers.com/zenfone-5z/how-to/guide-zenfone-5z-how-to-root-downgrade-t3815877
Use this file https://dlcdnets.asus.com/pub/ASUS/ZenFone/ZS620KL/UL-Z01R-WW-100.11.162.111-Downgrade-user.zip

Get a new downgrade zip that seems like it's a reg zip not downgrade zip
Try rollback packages from here

Thank you, i will try it!
Also I believe they mentioned a "rollback apk" in addition to the downgrade zip that needed to be used to roll back.
Forgot to mention that I am in 11.2.9.9

I have exactly the same phone and I have no problem running the India version. to run the global version wait for the next full global update. download it from the oxygen update and install it manually. I'm gonna do the same because I would Ike running the global version before oxygen Os 12 come.
Thank you for your response, that's what i want to do, run global before Oxygen 12.
I have a Oneplus 9 pro which I bought from a chinese company in Hong Kong - Bludiode.com - I have been told it has Hydrogen OS on it but nothing says Hydrogen OS anywhere? It has just updated to Android 12 with a couple of updates recently. Is there any way I can check what it has on it. I always have been able to use Google and everything has worked well but the latest Android 12 has stopped the Amazon Alexa app working properly. Not fantastically worried but hey.
Where should I go from here? Some say change to OxygenOS but not sure if this is possible. Should I change to ColorOS and then OxygenOS? I'm in the UK.
Inspire me....

You will need to search for a11 downgrade zip from a12. Le2125 is global varient so you need the global downgrade package found here

Ps back up all your data when you downgrade it will wipe your phone. This will take you back to a11 and you can update to oos12 from here if you like. Still to many bugs for me in a12 right now.

I'm a complete novice so please be gentle!! It says downgrade from OOS12 to OOS11. I don't have OOS12 - It's Hydrogen so is this the right file?

I have got as far as downloading the 2 files to the root BUT
The Local Upgrade as well as other system update options are not visible under the Update Settings page. So how do I install these? They don't install automatically and there is no way that I can see to install them?

Hello,
Could you help me please with switching from ColorOS12.1 to Oxygen OS 12?
I was reading the forum and found few guides how to do it and they are all related to downgrading to ColorOS 11, however, when I'm trying to do it it is always showing me "Verification failed" for downgrade file ROM. I have downloaded around 3 or even 4 different files but none of them worked.
Is there a way to switch to OxygenOS 12 without unlocking bootloader?
Thank you.

Hey everyone,
Two days ago I got the new update, I believe it is OxygenOS 12.1?
While it claims improved stability, the opposite is true for me, especially regarding mobile network connections.
About the new version, the update-log specifically says "Communication: Improves the stability of mobile network connections."
However, after the update, I can now only stay on my mobile network for 5-10 minutes before it shows the exclamation-mark error in the top right corner on the connection status, and the network doesn't work.
I then have to go into the settings, disable my SIM-card, enable it again, and then it works for 5-10 minutes again before it stops working again.
Before the new update, I used to have zero issues with my mobile network connection.
WiFi works fine, the issue is only regarding mobile network connection.
Does anyone know what I can do to fix this?
Please let me know if you need any further information about my phone.
Thanks in advance

Depending on your model you may not have a local update option. If not, then install this apk
