..

Problem with those models and other models are they have
epoxy under the BGA. Unless you are ready and know how
to remove that epoxy. It will be very difficult. Too much heat
will cause the BGA balls under the chips to expand and pop..

Must heat bottom with heater and heat top by 290 degrees
wait till it comes off. Too much or fast heat is bad. Solder pops..

heater on bottom 190 degrees
top 290.. slow heat
