!!! Factory reset will erase all your personal information !!!
If you forgot you password, pattern drill, there are three ways to bypass the security:
- You can log-in in your phone by Google account registered on this phone. You must be connected to a WiFi network that you have used before.
- By entering Backup PIN, if you had created one before.
Finally, you can do factory / hard reset. By doing this you will erase all personal information from the phone and you will back it to its original factory state.
