How do I deregister my kindle

To buy content and deliver it to your device, you will need to connect to a wireless network and register your Fire tablet to an Amazon account.
If you are setting up a new Fire tablet for the first time, you'll be taken through setup instructions and will have the chance to register your device. Follow the instructions on your screen.
To register your Fire tablet outside of the initial setup screens:

1. From Home, swipe down from the top of the screen and then tap Settings.
2. Tap My Account.
3. Tap Register.
   • If you already have an Amazon account: Enter your Amazon account information, and then tap Continue.
   • If you do not have an Amazon account: Tap Start Here, and then follow the instructions to set up a new account.

Note: If you've forgotten your Amazon account password, you can reset it by requesting that a personalized "password reset" link be sent to your e-mail address. To learn more, go to Reset Your Account Password .
If you need to deregister your device from an Amazon account, follow the steps above, and then tap Deregister. After you deregister your device from an Amazon account, you won't be able to access items stored in the Cloud for that account.
After deregistering, you can register your Fire tablet to another Amazon account. Related Help Topics

To deregister your Kindle Fire tablet:

• From Amazon.com, go to Your Apps and Devices.
• Click Your devices.
• Click the Actions button, and then click Deregister device. Deregistering your device prohibits Appstore purchases on that device, and disables the use of any app purchased from Amazon Appstore for Android and downloaded to that device. You can re-enable purchasing from the device by signing in to the Amazon Appstore for Android again.

You can also reset the device after you deregister, so once you register you device will be like new:

• Slide down the top menu and tap "More...":
• On the Settings screen tap "Device":
• At the very bottom you'll see the option, "Reset to Factory Defaults".
