There are multiple ways to reset your device if you are experiencing issues. Power cycling your device is the first step. In this tutorial, you will learn how to:
• Power cycle your device
• Restart your device
• Reset network settings
• Perform a factory data reset
• Perform an alternate master reset
Power cycle your device

Restart your device
If a power cycle does not resolve your issue, perform a device restart. Press and hold the Power/Lock button, then select Restart.
Note: If you are unable to turn your device off, remove and re-insert the battery. For more information on removing and re-inserting the battery, please see the Phone Assembly tutorial.
