How to remove parental control on Amazon Kindle I have an Amazon Kindle Fire HD with parental control, but I have forgotten the code.

How can I remove it without losing anything?

I think it involves some kind of "reset", but I want to be sure I won't lose something from the device before I start and that I won’t have to spend a lot of time re-sending stuff to it.

I see something about de-registering, so perhaps it is not so difficult, though when I try to do it, parental control is blocking me, also it is blocking me from connecting to the Internet with Wi-Fi.
Look at this amazon help forum about this issue. I found this:


  This is a bug in the kindle. Don't reset your device people!!! Just go onto your amazon account and "manage your device" and deregister it. That resets the parental control password. Go to the device and hit resync. When thats done go into the settings gear, my account, and register it using your amazon account info. It will be as before, nothing lost. I just got off the chat with a helpful amazon tech rep who gave me this information.


Also take a look at this answer on a forum found at askville.amazon.com:


  
    If you forget your password, you can deregister your Kindle Fire from Manage Your Kindle (www.amazon.com/manageyourkindle) to reset the
    parental controls password. Deregistering your Kindle Fire will also
    allow you to keep any downloaded items on your device. Once your
    Kindle Fire has been deregistered, tap Sync from the Quick Settings
    menu on your device, tap More, then select My Account to reregister
    your device.
  
  
  If you're unable to deregister your Kindle Fire from Manage Your
  Kindle, you'll need to reset your device to the default factory
  settings to regain access. If you've added any personal documents,
  music, videos, or other content to your Kindle Fire, ensure it's been
  backed up prior to resetting your device. Resetting your Kindle Fire
  to the default factory settings will delete all content on your device
  and you'll need to register it again before downloading items from
  your Amazon account.
  
  To reset your device to the default factory settings:
  
  K6:
  
  
  Tap the Quick Settings icon in the top right corner of the screen, then tap More.
  Tap Device, then tap Reset to Factory Defaults. 
  
  
  K9 / K9-HD / K10:
  
  
  Swipe down from the top of the screen, then tap More.
  Tap Device, then tap Reset to Factory Defaults.
