The Need for Manually Upgrading OxygenOS

OnePlus is well-known for providing dedicated software support for all its phones and the OnePlus 8T is no different. Ever since the phone’s launch, the company has rolled out monthly security updates in a timely manner. Recently, they also released the OxygenOS 11.0.12.12/11.0.11.11 update that brings December 2021 patch along with some other improvements.

Like any other Android device, OxygenOS updates for the OnePlus 8T are rolled out over-the-air, more commonly known as “OTA updates“. Since the rollout is staged, these updates are made available for a small percentage of devices initially, followed by a wider rollout in the following days/weeks. This ensures that no critical bugs are present in the update before it’s available for everyone.

This also means that you’ll often need to wait for the latest OTA update to arrive on your phone. Well, not necessarily. If you wish to upgrade your phone to the latest OxygenOS version right now, then you can simply download the latest OxygenOS OTA package for your OnePlus 8T from below and install it manually.

Tip: Alternatively, you could also use the Oxygen Updater app to immediately get the latest updates on your phone.

Before you attempt to manually upgrade your phone, it’s strongly advised to check if the OTA update for automatic installation is available for your device or not. To do this, go to “Settings” → “System” → “System updates” on your phone.

Before You Begin

Before you head to the installation instructions, there are a few things we suggest you do.

1. Take a Backup: Manually installing updates does not erase any data on your phone. However, to be precautious and for safeguarding, make sure that you take a backup of all your data stored on the device.
   You could take a look at our article on backing up different types of data stored on Android devices.
2. Install OnePlus USB Drivers (if required): Download the latest OnePlus USB drivers and install them on your Windows computer.
   These will only be required if you download the ROM package on your PC and need to transfer it to your phone’s storage during the installation instructions.
3. Charge your OnePlus 8T: Charge your phone to a minimum of 40-50% battery level. This will ensure that it doesn’t suddenly power off due to low battery during the software update process.
