  • Scenario A: If you bound the account more than 168 hours ago, the tool will immediately unlock the device.
  • Scenario B: If you are within the 168-hour window, the tool will display a countdown timer (e.g., "Wait 142 hours"). You must leave the phone and PC as they are (you can close the tool and come back later) until the time expires. There is no workaround for this in v6.5.406.

  3. If successful, you’ll see a progress bar (1-2 minutes).
  4. Once complete, the phone reboots and performs a factory reset.

Success Screen: “Unlocked successfully” in green text.
