Man, I must still be a n00b, I haven't really killed any hardware expcept for an ATA cable that I tried to round. I don't have a shim, I've taken my block on and off about 10 times trying to unlock my chip. The one thing I have done is tried to unlock my XP with a soldering iron, bad idea if your iron has a huge tip. Sooo, my chip works fine, but I think it's neutered and won't unlock since one of the bridges is scortched. Oh well, it was only a 1600+ to last me until t-bred comes out
