Need help putting phone into DFU mode.

I've searched the forums and looked on the web elsewhere, but I just keep locking my sim card. Could someone explain how to put it in DFU mode please. I've done it before but it's been a while. Thanks in advance!

Figured it out. Seems like there is multiple ways to do this.
