I use a lenline brush to clean traces and lay a bit of wire over it and add solder then cut any excess wire away.

I did my cuts with a sharp utility knife. Not too deep though, as not to cut embedded traces in case its a layered PCB. I then *GENTLY* scraped a little of the solder protector from each side of the trace. I used rosin core solder and placed it directly onto the cut. I placed the soldering iron on top of the solder which melted it almost instantly, then lifted the soldering iron away and verified that I actually did a connection visually, and then I used my ohm-meter on continuity mode (where it beeps when you touch the leads together), and touched one end to the VIA that was disconnected, and the other end to another via on the opposite side of the cut. If the meter beeps, your cut was sucessfully bridged, if not, try to gently touch up your solder without applying excessive amounts of PCB-Death-Heat (IMG:style_emoticons/default/biggrin.gif)

Good luck!

Use a #2 pencil make sure you overlap on the existing trace worked on my PSP

if a silver conductive pen didnt work, I really doubt that a pencil will work. There is too much resistance and the drive still thinks its in zero logic and causes a RRoD on the 360 with secondary error code 0021 = dvd drive timeout. For people who intend on TRYING to go on live, you really dont want that. I dont care because my xbox will never see live so its all good. Is it worth the risK?

What traces did you cut. and a dab of solder should do! Can someone make a better picture of what needs to be cut? I hear its two traces but i see a line going through two traces and a line over one trace?  Thanks a ton guys? (IMG:style_emoticons/default/biggrin.gif)
