OnePlus Unbrick Tool (MsmDownloadTool) can also be used to rollback the user’s phone to a previous release of OxygenOS.
Talking about the unbrick tool, it is a low-level flashing utility that can revive individual bricked OnePlus devices. The flasher utilizes Qualcomm’s Emergency Download Mode (EDL), which means you can restore your device even when you don’t have access to the Fastboot interface.
The tool can also be used to rollback the user’s phone to a previous release of OxygenOS. It should work with the Chinese, Indian, European, and North American unlocked variants of the phone.
