OnePlus Update Introduces Anti-Rollback, Risking Phone Malfunction
OnePlus has introduced a significant update to its OxygenOS operating system by implementing new anti-rollback measures. These measures enforce users to remain on the latest software versions, preventing any downgrades to previous versions.
Anti-Rollback Features in OxygenOS
The recent ColorOS update, version 16.0.3.501 and newer, now includes a hardware-level anti-rollback mechanism, as reported by developers from the XDA forums. While this change may not directly affect average users, it poses serious risks for enthusiasts who utilize custom ROMs.
Impact of the Update
- Downgrade Risks: Attempting to flash any version of ColorOS or OxygenOS older than 16.0.3.501 will result in a hard brick of the device.
- Custom ROM Compatibility: Flashing any custom ROM released before this update on top of ColorOS 16.0.3.501 or later will lead to an immediate hard brick.
- Unbrick Limitations: Existing unbricking methods, including unauthorized 9008 tools and Chimera firehose programmers, will not work due to the blown fuse.
This update currently applies to the OnePlus 13, OnePlus 13T, and OnePlus 15. Meanwhile, older models like the OnePlus 12 have yet to receive similar anti-rollback implementations but may in the future.
Contextual Changes and Future Implications
While the functionality of anti-rollback mechanisms can be beneficial, the rationale behind OnePlus’s decision remains unclear. For instance, Google used a similar feature in its Android 13 update for the Pixel 6 series for security reasons. OnePlus has not provided any public comments regarding this update.
Significantly, reports indicate that OnePlus has started removing rollback packages for the OnePlus 13’s OxygenOS versions. This suggests the anti-rollback policies are currently in effect and may expand to other devices soon.
As this situation unfolds, OnePlus users should remain vigilant and consider the implications of these updates on their devices, particularly those who prefer custom software modifications.
