This error typically occurs when there is a problem with your Android Debug Bridge (ADB) drivers. One Click Root uses a universal driver which aims to support all devices, but in some cases, you may need to manually install drivers from the device manufacturer’s website.
ADB drivers are notoriously unreliable. After manually installing your drivers, try restarting your PC before running One Click Root a second time.
The “Unable to find Android device…” error will also occur when USB debugging is not enabled on your device.
