Trying to RGH my Xbox 360

Hello guys, Im Andoryu and I need y’all help.
An hour ago, I wanted to make my Xbox 360 RGH, but I might have met a problem. My soldering iron wasnt that good as I expected so I did a mess. The most awful thing is that I might did some bad things at the back of the MOBO like to accidentally solder cuz of a small pin. Now the console doesnt want to turn on and the power brick LED is turning red.
The questions are:

  1. The solder I accidentally made would make short, so it would affect it?
  2. How I can remove the solder?
