I once tried to replace a screen on an iPhone, and accidentally knocked a barely visible capacitor next to the connector right off the board. When I say barely visible, I’m not exaggerating. I did try to solder it back onto the board under a microscope with my cheap reflow station, but it was absolutely futile. Which is to say, as difficult as this video looks, this is being done by a person who has done similar things many times, and you’re very unlikely to be successful at this the first time around. Tread carefully.
