Do not make a thread that isn't clear, some people may "semi brick" their phones by doing this.
Well I personally cannot test this, I have device that can run it, but my friend used these instructions and was fine, so were the people in the comments section, it's like having a jailbreak. There is a possibility of bricking the iDevice but fixing an iDevice is just a case of either a normal restore of a DFU restore.
