This OEM always had this reputation of releasing timely Android upgrades. And they stood true to their promise, at least for their flagship series. However, that wasn’t the case with its seventh series of devices. Due to data encryption issues, they had to work day in out with Qualcomm in rectifying this issue.
But finally, the wait time is over and as of now, users have received the At the time of writing, these devices have received the Open Beta 1 update. With that, there are a plethora of new and noteworthy features that you are likely to welcome. The biggest change that you are likely to welcome is the complete UI overhaul (just head to the Settings page and you’ll get the idea). Then there are a few additions to the camera (of which the ability to directly share the image via thumbnail came out to be my favorite).
Likewise, there are some Android 11 exclusives such as One Time Permissions, revamped power menu, Screenshot Share menu and he likes. However, even then there are quite a few issues bugging the end-user and many of them have already made up their mind to switch to the earlier stable build.

Bugs in OxygenOS 11 Android 11 Open Beta 1 for OnePlus 7, 7 Pro, 7T, and 7T Pro
These are the officially documented bugs that OnePlus has listed out on their forums:
- Potential risks of increased power consumption and instability.
- In some conditions, the Gallery app might be slower to load and some pictures may not be displayed in the Gallery.
- The devices (earphones, speakers, etc.) connected through Bluetooth may not be able to play sound occasionally.
- Brightness adjustment may lag in some conditions.
Apart from that, I did a few explorations myself and managed to found out users complaining of issues related to their inability to set up Fingerprint Scanner, OnePlus Launcher, and Settings keeps stopping, some are not able to set their device refresh rate to 90HZ, and are stuck with 60Hz and the inability to use AOD. Likewise, there are quite a few more that aren’t as major as the aforementioned ones.
And let’s not forget the fact that the OTA that OnePlus rolled out erased all the data on the user’s device. While it is always recommended to take a backup beforehand, but some decided not to do. This is because OnePlus official instructions clearly say that you don’t need to take a backup if you are upgrading from stable MP to Open Beta OBT. The OEM was quick on its part to remove those links, but even then, there were already a few infuriated users who lost most of their data.
All in all, there are many users who have now made up their minds to go back to the earlier version. So if you are looking to perform the same, then this guide shall come in handy. Here are the detailed instructions to rollback or downgrade the OnePlus 7, 7 Pro, 7T, and 7T Pro to OxygenOS 10 Android 10 from the newer OxygenOS 11 Android 11.

How to Rollback/Downgrade OnePlus 7/Pro/7T/7T Pro to Android 10 OxygenOS 10
Here we would be doing a rollback from the newer OBT to the previous OBT build. Yes, that’s correct. As of now, it isn’t possible to rollback to the MP build. In other words, we would be doing a downgrade from Android 11 Open Beta 1 to Android 10 Open Beta build and not the Android 10 stable build.
Furthermore, in the case of the OnePlus 7T and 7T Pro, you will have to install this rollback package twice. This is because, during the first installation, it will only delete a few system apps. To perform a full downgrade and remove all of them, it requires you to flash the downgrade package once more.
As far as the OnePlus 7 and 7 Pro are concerned, only a single install is needed, no need to install it twice. So with that in mind, let’s get started with the guide to rollback or downgrade the OnePlus 7, 7 Pro, 7T, and 7T Pro to OxygenOS 10 Android 10 from the newer OxygenOS 11 Android 11. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
STEP 1: Take a Backup
This process will wipe off all the data from your device. So make sure to create a complete device backup beforehand.
STEP 2: Download the Android 10 OxygenOS 10 Downgrade Firmware
Now, download the OxygenOS 10 based on Android 10 downgrade firmware for your deivce and region from the below links. As mentioned before these are the Android 10 Open Beta OBT builds and not the Stable MP build.
STEP 3: Install Android 10 Rollback File on OnePlus 7, 7 Pro, 7T, and 7T Pro
- To begin with, download the downgrade zip package for your specified region.
- Then transfer it to the phone storage, but not within any folder.
- In some instances, it might be having the extension JAR. If that is the case, then rename it from JAR to ZIP. For that, just remove the .jar word from the end. You will then be left with the filename.zip.
- After this, head over to the Settings page on your device and go to System.
- Then go to the System Update section.
- Tap on the gear icon situated at the top right.
- Select the Local Upgrade option.
- Now navigate to the downloaded update firmware file and select it.
- Hit the Upgrade button and wait for the process to complete.
- Once, the upgrade is complete, click Restart. Your device will then be booted to the Android 10 OS. If you are a OnePlus 7 or 7Pro users, then your task stands complete.
- On the other hand, the OnePLus 7T and 7T Pro users need to reinstall this downgrade ZIP file. You should use the same procedure that we did just now (via the Local Upgrade option). As soon as you have installed the rollback firmware onto your device, hit the Reboot option and now your device will restart to Android 10.
That’s it. These were the steps to rollback or downgrade the OnePlus 7, 7 Pro, 7T, and 7T Pro to OxygenOS 10 Android 10 from the newer OxygenOS 11 Android 11. If you still have any queries, do let us know in the comments section below. We will get back to you with a solution at the earliest.
