I followed the instructions to a tee. Trying to save my old info/motherboard from my galaxy III that has a smashed screen, so I bought a used one and put my old motherboard in it. Everything went perfectly except the most essential thing - the on/off switch for the phone doesn't match up anymore. There's no way for me to turn on my phone on or off unless I go through steps 1-14 and proceed to use a needle to turn it on. I might as well use both phones as door stops now. If anyone wants a motherboard or 2 feel free to contact me before I chuck 'em over a cliff.
