Remove and remount entry door frame

Well, here goes. I am about to replace my entry door hinges for the second time. Needless to say, during the last replacement, I let the mount plates behind the frame fall to the bottom because I didn't know they were there. To keep the new hinges tight, I up sized the mounting screws as recommended. The fix has not lasted and the ongoing slight loosening of the hinge mountings has caused door sticking and closing problems. The hinges also don't respond well to this and get bent. I am going to try and remove the frame, retrieve the plates and remount the frame. Since I am insecure as to the remount being within my skill set. I need to know if anyone has any first hand knowledge, personal experience, tutorials or videos that I can refer to.
