I have forgotten the pattern or password needed to unlock my Walkman.

Check the following according to the type of screen lock you have set.

1. Locked by a pattern
   
   When you lock the Walkman by a pattern, you can reset the pattern by answering the security question or via your Google account.
   If you cannot answer the security question or your Google account is not registered to the unit, the only option will be to perform the Android system recovery procedure shown below.
    
2. Locked by a password
   
   If you lock the Walkman by a password, you cannot reset the password. The only option will be to perform the Android system recovery procedure shown below.
