    Hi

    I need some help with my V3 modchip. First, I'll post a little backstory of my ignorance (feel free to laugh at me, ridicule me, etc.) I have a Japanese HST-0014 Saturn. When I first got the chip, I noticed the pads had a little slight raised look from the metal on top of them, but in the guide, the pads are basically flat with no metal on top. The reason I'm bringing this up is because when I first got the chip, I stupidly bought a bernzomatic microtorch to use to solder with. I was unware that on its lowest setting was probably more heat than neccessary to solder with. The solder itself was 1mm in diameter. I practiced bridging a few things on an old network card with some success beforehand; although when it came time to bridge the connections on the chip, there was too much solder. So I got my desoldering braid and removed most of it. I was hoping that the excess heat from the bernozmatic didn't damage the board in the removal process. After I removed it, the pads were completely flat and didn't have the sloped appearance they'd had prior. So at that point, I adopted a hands-off approach. I called my friend, who helped me with it. He used a very thin piece of wire to bridge the 0014 connection. The thing is, I'm not even sure if he made a good connection. I mentioned before that the metal that was on the pads pretty much disinegrated. Is the chip still even usable? We installed the chip and I tested it the other day and the drive did not spin at all, but I'm not sure if his solder connection to the 5V power was very good. Anyway, I don't know how to go about troubleshooting this, since I have no soldering experience. Is there any way to test the chip to see if it's still good? The chip itself doesn't LOOK badly damaged, aside from the metal on the pads missing. And I've read about people having to bridge the 0019 connection instead of the 0014 one to get it working. I'd appreciate any help and will post a picture as soon as I can find my camera.

    Did the photo I edited for you work? In case anyone is wondering he sent me a PM with these photos and following the traces to the pads I pointed out which are some alternate points to solder to.
