i would not say easy - depends on what kind of soldering/de-soldering tools you have. good news it only has six leads,
bad news is it has a thermal pad center bottom that i bet is soldered down also. hopefully someone with more surface
mount experience than i have can weigh in on that.
but i think first you should feel the cpu - is it at least warm? also hold down the pgm button for 15 seconds and when
the red led comes on dim let go of the button - then the red led will get bright for about 30 seconds and then the
yellow led will blink at 1 second intervals. if all of that does not work, measure the 5v from your computer on the pin
labeled 5v - if it is low then the blown regulator is dragging down your usb supply. if 5v is ok measure the 3.3 volt
output of the board on the pin labeled 3v, if it is 3.3v regulator is ok, if it is 5v the regulator is shorted input to
output and it likely fried cpu etc. if it is near zero volts then either the regulator is blown or it is being dragged
down by a blown cpu or memory chip.
if the yellow led does blink, unplug it, reboot your computer, plug it in and try to send it a known good program
and see if the red led blinks when you either say upload or hit the program buttom on T4. sometimes you have
to repeat that cycle a couple of times to get everybody synced up.
