How To Open Fastboot Mode On Asus Rog Phone 3 ❲TESTED · PLAYBOOK❳

If your ROG Phone 3 can still boot into Android normally, use ADB (Android Debug Bridge). This method is faster and avoids button timing issues.

This is the most common method and does not require the device to be fully booted into Android.

If your phone is on and has USB Debugging enabled, you can reboot into Fastboot via a PC.
