8015402b is an error code that means the user's account could not be accessed because the user's password is incorrect. This error code can happen for a variety of reasons, including if the user entered their password incorrectly, if their account is locked, or if their account is disabled.

1. Try restarting your console

  2. Click on the "Start" button and select "Run".
  3. Type "cmd" into the "Run" window and press enter.
  4. At the command prompt, type "reboot" and press enter.
  5. If the system fails to restart, try to reset the power to the console by unplugging the power cord from the back of the console and plugging it back in after 30 seconds have passed. If the power reset does not work, you may need to replace the console.

2. If you have a Kinect, make sure it's properly plugged in and not obstructed

  1. If your Kinect is not properly plugged in, plug it in and try to start the device again.
  2. If your Kinect is properly plugged in and the device still fails to start, it may be obstructed and you will need to take it to a service center to fix it.

  1. Log into your LinkedIn account.
  2. Click on your name in the top left corner of the screen.
  3. On the Profile page, click on the Edit Profile button.
  4. On the Edit Profile page, click on the Delete Profile button.

4. Try clearing your system cache

  2. Click on PC Manager and then on the "System Tools" tab.
  3. Click on the "Clear System Cache" button.
  4. Click on the "OK" button.

5. If you have an Xbox One, make sure your power supply is properly plugged in and that the light is green

  1. Look at your Xbox One's power cord to make sure it is properly plugged in.
  2. Look at the light on the front of your Xbox One. If the light is green, then your power supply is properly plugged in and the 8015402b error code is not likely the cause of your problem. If the light is not green, then your power supply may not be working properly and you should replace it.

If the answers above didn't work then you should also try:

  1. Try connecting to Xbox Live using a wired connection.
  2. If you're using a wireless connection, try moving your console closer to your router.
  3. Check your network settings and make sure your console is set to the correct IP address.
  4. Try connecting to Xbox Live using a different network.
  5. Contact Xbox Support.
