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

In this guide, we will show you the steps to downgrade your OnePlus 9/Pro device from Android 12 (OxygenOS 12) to Android 11 (OxygenOS 11).

You will need to install the local update app found on this page to use the downgrade package
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,
I've just bought fresh new and sealed OP5T 8/128.
I've got ONEPLUS A5010_43_171115 build (Android 7.1.1, Oxygen 4.7.2) installed on the phone.
How can I update it to Android 9 or straight to the 10? The OTA doesn't show any updates and when I tried to install 9.0.11 using local file from the official OnePlus website, the installation failed
Thanks for your help in advance

Use Oxygen Updater from the Play Store. It'll show you the latest version you can update to safely (it will most likely be OOS 5.1.4, which creates the vendor partition). Once done, re-open Oxygen Updater and it'll show OOS the next latest you can update to safely (and this should be OOS 10).
You need to install 5.1.4 first, then update to 10

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.
Hello all,
I understand that there are local update files to rollback to android 11 from 12 but is it possible to still use the A11 msm tools while on Android 12 OOS available to us ??

MSM tool does not depend on the OS, I personally haven't used it on the 12 but it should work fine and restore your device to its own version. As always take a backup before you start as it will wipe all when you use the tool. Here is the reference thread for the tool.

Yes, I did it several times.
I am on c48 EU rom how to flash the global Rom
My device is LE2123 non rooted
Just download the stable full update via Oxygen Updater and install it. Works fine. Keep in mind to avoid updating to India version from eu/global. It is not stable.
I, and several others, who have EU (LE2123) versions had updated to the India version C60, however, we are not able to update (OTA) to C61.
Previously, on OnePlus phones when flashing other firmwares from other regions you would still be able to continue getting updates for that region. But with these latest OOS12 firmwares that might not be the case. So keep this in mind before changing regions.
Mine eu on c60 in worked like crap. Camera issues, overheating, bloatware installed... That was not a good move. Had to revert back to Oxygen 11 and move updates to global.
Try this : downgrade to region specific Android 11 ( IN/NA/EU ) and after that you will recieve ota. I personally downgraded to 11 ( GLOBAL ) ( i hasve eu version ) and i recieved c61 OTA.
Yep, did the same. C6Q global runns pretty good (not as good as Oxygen 11, I hate new UI, but it's quite good).
If I downgrade, I lose my data and my banking apps are running. Can't I download the full zip from global and import it via local update when its work lose my data ?

Thanks for the feedback. Few questions if you don't mind:
You have EU model (LE2123) and have successfully update C61 global firmware (LE2125)?
Did you flash the C61 global OTA update manually? I mean by downloading the OTA zip and flash it using local update? Or did it update by checking new updates using the normal way?
I understand that you switched to global using the OOS11 downgrade zip, so you had global firmware since OOS11 then upgraded to OOS12 (still global), does the about device Model show as LE2123 or LE2125?
1. Yes
2. No, did it via incremental update using system update app. First I downgraded using msm tool to global Oxygen 11, then followed all updates as far as cyq using system update app. Then I performed full wipe just to be sure all updates went well.
3. It still shows as 2123. No issues anyway (except red cable program from OnePlus - when I try to connect my device it shows wrong area, but I don't care ).

Updated using System update app, you mean the stock/standard update method (Settings>About device)?
Yes.
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!
Link: https://community.oneplus.com/thread?id=1181216999612088323&fromCircle=true
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?

This rollback method will erase all the contents of the phone, please be sure to backup first.

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.
