I broke my other dreamcast please help

[Gromber]

i wanted to remplace the original bios with a pre-flashed rom.

I can´t do it work on a ntsc-u va1 (black sport), i tried two times, with different pre-flashed roms... I am afraid that I have broken my motherboard (some welded track) when i extract one of them, please help.

I use the image


of this tutorial http://www.mmmonkey.co.uk/console/images...44.jpgthis tutorial

Can someone give me some advice or new pics.
There are alternative points to use with some legs of the bios?

A dreamcast less in the world...
