I Possibly fried X-ecutor 2 Lite Chip!!HELP

[spacedog147]

I made several attempts at installing the X-ecutor 2 Lite Mod.
Every time it would do the blinking red 3x thing. I kept checking all the wires and tried one last time. This time, I soldered the D0 to the bottom of the board instead. I booted up once again and immediately smelled the odor of burning electronics. I immediately shut the system down. I removed the D0 wire at the bottom and saw that the solder on the bottom of the board may have touched the metal Xbox case. I re-soldered D0 to the top position and the system booted fine but did not recognize the mod bios nor did it indicate that something was wrong with the mod chip. I checked all the wires again and still no luck. At least the console still plays as normal but I really want to play burned games.
Assuming the X-ecutor 2 Lite mod is fried, could I purchase a easier to install mod such as the MatriX no solder modchip and hope for the best or is this just a waste of time and money.
Thanks to all replies.
