I am not to be held responsible if anything goes wrong when attempting this. This includes bricking your phone, flashing a bad image, causing WW3 etc. I am also not responsible for any files in this tutorial. They were all provided by other people.
There may be inaccuracies in this post that may lead to various things such as bricked devices so be warned. Let someone check it over first! If you see anything wrong, let me know and I will edit it!
