Well, I have never modded a box, so you know more about it than me. I'll still TRY to help ... I have read a lot of tutorials and completely taken my box apart on several occasions before I ever read anything about it. Have you thought to check and make 100 percent sure that you are making good contact on the d0 point (or did you only connect the top 2 points)? What did you scrape over them with (ie - are you sure you didn't damage them)? The Phoenix BIOS Loader is a softmod that loads an alternate bios so that you don't need a chip or connected tsop points. Even though you have already bridged the tsop points, the PBL will still work. There are plenty of tutorials on the site about how to use it, so just check the tutorials section if you are out of options (under the no mod tutorials). Any moderators or 1337 people that read this post that can correct me on anything, please do so.
