Download OxygenOS 11 Open Beta 3

Following are the links to download OxygenOS 11 Open Beta 3 for the OnePlus Nord. These builds are available for the Global, European, and Indian versions.

Global (AC01AA): NordOxygen_14.X.05_OTA_0050_all_2101292335_1996fb78c.zip

Europe (AC01BA): NordOxygen_14.X.04_OTA_0040_all_2101300043_f8a38d.zip

India (AC01DA): NordOxygen_14.W.03_OTA_0030_all_2101292335_b3da0ea5d17.zip

Method 1: For Stock/Unrooted Devices

First, download the latest OxygenOS 11 Open Beta full ROM package for your OnePlus Nord.

Once downloaded, connect your phone to the computer via the USB cable and enable File Transfer/MTP mode.

Copy the downloaded full ROM ZIP file to the root directory of your phone’s internal storage (Outside all folders).

Once the file has been copied, disconnect the phone from the computer.

Now, go to ‘Settings’ > ‘System’ > ‘System updates’ on your phone.

Then press the cogwheel icon on the top-right of the screen and select ‘Local Upgrade’. The system will automatically detect and fetch the full ROM package.

Tap on the update file and select ‘Install Now’ to install OxygenOS 11 Open Beta on your OnePlus Nord.

Once the installation finishes press the ‘Reboot’ button.

Your phone will reboot into the updated Android 11-based OxygenOS 11 firmware. Although not mandatory, but in rare cases, you might further have to factory reset your OnePlus Nord if you experience any unusual bugs/issues.

Method 2: For Devices Rooted with Magisk (without TWRP)

If your OnePlus Nord is rooted using Magisk, you’d need to follow a few additional steps in combination with the ones mentioned in Method #1. This will not only allow you to install OOS 11 Open Beta but will also retain Magisk root after the update.

The first thing you need to do is to ensure that your OnePlus Nord is rooted with the Magisk 21.x or Canary version. If you’re running an older version, change the ‘Update Channel’ in Magisk Manager to ‘Beta’ and then update Magisk to v21.2 by following the on-screen instructions. Reboot the phone once the installation finishes.

After your phone boots, you need to restore the stock boot image through Magisk Manager. To do this, open Magisk Manager and then tap on ‘Uninstall’ > ‘Restore Images’.

Now follow the instructions listed under Method #1 above and install OxygenOS 11 Open Beta 1 on your phone using the Local Upgrade option. DO NOT REBOOT the phone after the OTA installation finishes.

The last thing to do before you can reboot is to install Magisk to the inactive slot (where the Open Beta is installed now). This will allow your OnePlus Nord to remain rooted even after the update. To do this, open the Magisk Manager app

That’s it! Your OnePlus Nord should now boot into OxygenOS 11 Open Beta software based on Android 11 and should also be rooted with Magisk.
