Im heatgunning my motherboard tomorrow i tried today but didnt do it hot enough or long enough because i was trying to be very damage cautious. How long do you let ur heat gun warm up before starting? and how long should i keep the heat gun on the gpu/cpu do you recommend doing southbridge too? Please help Ive fixed many xboxs without resorting to reflowing but this one has given me 3 different error codes everytime i try a different fix. Its a xenon that was sold to me as a jtaggable for 30 dollars so id really like to get it running 8)
