Overview
OnePlus introduced Anti-Rollback Protection (ARB) to prevent users from flashing older firmware that could expose a vulnerability. While the measure boosts security, it also risks bricking devices if a downgrade is attempted.
Affected Devices
- Model: OnePlus 13, OnePlus 13T, OnePlus 15, OnePlus Ace 5 series
- OS: Applies to both OxygenOS and ColorOS variants
Security Rationale
The protection stops malicious actors from exploiting old firmware to wipe a stolen phone and sell it as functional. By locking the software version, OnePlus aims to keep the device’s data integrity intact.
Impact on Users
- Risk: Attempting a downgrade may brick the device permanently.
- Custom ROM Users: Installing a custom ROM now requires careful handling to avoid triggering ARB.
