This may have been already posted and asked but I just want to make sure. Recently I got myself a Kindle Fire HD 7, and I rooted it (because of the annoying geographical restrictions not possible of downloading free apps from the app store).
I would like to know exactly, on how to unroot the device and flash everything into factory default firmware? Reading through posts I see that I need a special "factory" cable in order to do this. Can someone please provide me a guide on how to do this, and where can I buy the factory cable from a genuine distributer?
All comments are welcomed & appreciated. Thanks!
