2. Attempt to power cycle the device into the Android Recovery Menu by pressing the Volume Button Down + Signal Key + Power Button when powering on the device (release the power button after the device powers on as it will turn the device off if you maintain pressure on the power button) and wait until the bar fully loads
3. Press the Voice Signal Key to attempt to Reboot System Now
4. If steps 2 & 3 don't work, then follow step 2 again to return to the Android Recovery Menu, use the device Volume Keys to select Wipe Cache
