OnePlus ARB Checker1.7.6

OnePlus ARB Checker reads the Anti-Rollback (ARB) index on OnePlus devices, helping you assess firmware updates before applying them. It verifies device and firmware information associated with ARB checks so update decisions are based on the device’s recorded software state.

With root access, its low-level hardware reading mode retrieves ARB data directly for verification. A separate database-based analysis mode examines software version information when direct hardware-level access is unavailable. Background monitoring can alert you before installing updates that have been identified as risky.

The app also provides firmware history with regional context for locations including GLO, EU, and IND, making regional update details easier to interpret. Its Material 3 interface supports Dynamic Color, while its offline-first design works with information already available on the device. These features suit OnePlus owners, Android enthusiasts, and technicians checking update safety during firmware maintenance.

OnePlus ARB Checker is an open-source Android app in the System Tools category, and version 1.7.6 requires Android 8.0 or later. It supports arm64-v8a, armeabi-v7a, x86_64, and x86 architectures; root access is needed specifically for the low-level hardware reading mode.
