In this guide, we will show you the steps to downgrade your OnePlus device from Android 15/OxygenOS 15 to Android 14/OxygenOS 14. The Silicon Valley giant has recently rolled out the red carpet calling out the OEMs over its latest Android 15 bandwagon. And quite a few OEMs have already accepted this offer, with OnePlus being the latest entry to this list. As a result of this, its flagships [and older devices over the due course of time] are about to be blessed with a slew of intriguing goodies.
In this regard, some of the noteworthy features include the likes of Partial Screen Sharing, Notification Cooldown, Lock Screen Widgets, Battery Health Percentage, App Archive, Bluetooth Menu, Private Space, and many more. However, one shouldn’t forget the fact that the OS is currently in the testing phase, hence a few bugs and issues are expected.
Moreover, issues like device overheating, excessive battery drainage, and system slowdown are literally the writing on the walls. This is the reason why it isn’t recommended to use the beta builds as a daily driver and are mostly intended for development and debugging purposes. However, if you are among those set of tech enthusiasts who like to test out the bleeding edge features before anyone else, then you might already have welcomed this latest OS release.
However, if these bugs and issues are proving to be quite an infuriating usage experience, then your best bet is to downgrade your OnePlus device from Android 15 OxygenOS 15 to Android 15 OxygenOS 14. And in this guide, we will show you how to do just that. So without further ado, let’s get started.

How to Downgrade from OxygenOS 15 to 14 via Fastboot Commands
In this guide, we will show you the steps to downgrade your OnePlus device using Fastboot Commands. While the OEM is usually not the fastest player to roll out the OS upgrades, and nor does it provide an aggressive 7 years of updates [as opposed to the likes of Pixel and Samsung], yet it follows quite a streamlined update process.
First off, it tests the alpha builds among the chosen few in the form of Closed Beta build, which is then followed by the Open Beta build, and once all the issues are ironed out, the update is rolled out to the stable audiences. With that said, a few bugs might still manage to creep in the update, not just in the beta but even in the stable ones.
Along the same lines, there have been a few instances wherein users aren’t a fan of the revamped UI that the new update has to offer. Then with every upgrade, a few features face the axe as well, which again tends to infuriate the users. Fortunately, the answer to all these three problems is quite simple- rollback to the previous OS build. And in this guide, we will show you how to do just that. So without further ado, let’s get started.
Why Choose Fastboot Method over Local Install
There are quite a few reasons why you would want to go for the Fastboot Method over Local Install, but the best use case scenario is when your device is currently in a softbrick or bootloop state [as the latter will not work in such cases]. Likewise, if you wish to downgrade to two or more OS versions at one go, then Fastboot is the preferred way of doing it.
Installation Steps
Now that you are aware of the benefits of this method, you may get hold of the firmware from the above link and then refer to the below-linked guide for the flashing instructions [Check out the “Flash OnePlus Firmware via Fastboot Firmware Flasher Tool” section]:
That’s it. These were the steps to downgrade your OnePlus device from Android 15 OxygenOS 15 to Android 14 OxygenOS 14. If you have any queries concerning the aforementioned steps, do let us know in the comments. We will get back to you with a solution as soon as possible.
