1. Hold the button until it starts vibrating, then keep holding until it turns off.
2. Press the button to turn it back on and then QUICKLY (as SOON as the LG logo shows), swipe from 11 o-clock to 5 o'clock (diagonally) on the screen to enter the bootloader.
3. Once you see the bootloader, tap > until the red text says RECOVERY MODE, then tap O to boot into recovery.
4. Once you see the green droid robot, tap the screen to bring up the recovery menu.
5. Swipe down until the factory reset option is highlighted, then press the button.
6. Swipe down until Yes is highlighted, then press the button.
7. Wait for the factory reset to complete.
8. Swipe up to highlight "reboot system now" in the recovery menu if it's not already highlighted and press the button to reboot.
9. Wait until the watch boots into the setup screen - this will take about 3x-5x longer than a normal boot, so be patient.
10. Set up the watch with your phone.
