Amazon Kindle Fire Unbrick Utility
XDA Member Zombiepiratez has created a helpful little program for Windows that will help you fix the brick. It runs in Windows Command Prompt, so the UI is dead simple to use and the selections are easy to understand, so noobs need not fear in terms of difficulty. Unfortunately, Zombiepiratez has sustained personal injury, as he says:
Unfortunately, I have broken/sprained my wrist, and am unable to move my fingers without a fairly great amount of pain. This is only my right hand, but sadly, I am right-handed. For the next month, I will be unable to code, meaning no new versions or bugfixes.
So, if you find a bug, feel free to report it and don’t get discouraged if you don’t hear back.
