When im dumping nand with soder boards do i de soder on the xbox motherboard?

[TX Nand X]

Do i desolder the holes on the xbox360 motherboard when i install the quick solder boards to it

No, you only do that if you are installing the pin headers. I suggest you search the forum and do a bit of reading about soldering before you ruin the points on your 360 board.
