I am not responsible for anything bad that comes to your device when using the information posted in this thread. Everything here is dangerous, may cause a brick, will void a warranty and has the potential to just plain wreak havoc. Do not complain you followed my instructions and met with a dead device. Consider yourself warned
I've tested to the best of my ability, but I am one person with one device, I cannot catch all potential failure modes. If you find a problem and a fix, or have information that should be added let me know and I will update the necessary information.
