OnePlus's New Update: Locking Your Phone's Future
TL;DR:
OnePlus has introduced a new feature called Anti-Rollback Protection (ARB) in recent ColorOS updates, which permanently locks your phone's software future. This means you can no longer downgrade to older firmware, install custom ROMs, or use most unbricking methods. If you unlock your bootloader or flash ROMs, avoid ColorOS builds ending in .500, .501, or .503. The change affects the OnePlus 13 and 15, and may soon expand to older devices and OxygenOS builds.
The Controversial Change:
OnePlus's new system is a major behind-the-scenes update that could permanently affect bootloader unlocking, custom ROMs, and software downgrades. While it's designed to prevent downgrades to older, less secure firmware, it may also limit your ability to customize your phone. The company has already implemented this feature on select devices, and it's causing a stir among users who value the ability to unlock bootloaders and install custom ROMs.
What is ARB and How Does it Work?
ARB is a hardware-level fuse that trips when you install specific ColorOS builds. Once tripped, it cannot be reversed through software, and the only way to restore your phone would be to replace the motherboard. This fuse is part of Android's Verified Boot framework and works similarly to Samsung Knox. If you unlock the bootloader on Samsung phones, you trip the fuse, but Samsung's implementation isn't as strict.
Affected OnePlus Devices:
Droidwin confirms that ARB is already live on the following devices:
- OnePlus 13 and 13T: ColorOS 16.0.3.501
- OnePlus 15: ColorOS 16.0.3.503
- OnePlus Ace 5/Ace 5 Pro: ColorOS 16.0.3.500
The OPPO Find X8 series is also at high risk, and the OnePlus 11 and 12 may be next in line. It's important to note that ARB has only been reported on ColorOS, but it could expand to OxygenOS in the future.
What to Do if You Care About Customization:
If you value bootloader unlocking or custom ROMs, it's best to avoid installing updates ending in .500, .501, or .503. This will help you preserve your phone's customization options and prevent permanent software locks.
Stay Informed:
As always, it's crucial to stay informed about your phone's software updates and their potential impact. Keep an eye on OnePlus's official announcements and follow reliable tech sources to ensure you make the best decisions for your device.
