HTC myTouch 4G

I have been trying to Root my phone for the last week and half and I am not successful. I have done EVERYTHING, every video and messaging board I have read. EVERY step. AND, I STILL CAN NOT GET THE S to TURN OFF and root. If you wouldn't mind I ming on AIM (Ichat) knockattheduir or Yahoo Therealsteve2000 and do a video or just i m chat and help me with this, I will be forever thankful. I just don't know what to do now. Because I have done everything!
