I've done a lot of phone repairs, but I've never swapped a motherboard. My friend dropped her LG Connect in water and didn't turn the phone off or even bother to clean it out before using it again. The board is fried. I just ordered an LG Connect board off of ebay that is tied to Metro PCS (her carrier), and it has a clean ESN. How will the switch work? Will the phone have to be deactivated and the reactivated when I put the new board in? Or will everything work seamlessly after I put the new board in?
