I understand that many people have been having the issue of installing ROM manager. (I did it myself). I am looking for a do it yourself guide on how to return the phone to a bootable state. Is there hardware that needs to be replaced when it is done? Or am I able to make a jig or something? So far i have followed the steps for a 300 ohm jig and nothing worked. I have also tried to use the hard recovery keys to put it into download mode and still nothing at all. Not even a blink of the screen. Can someone please help?
