if you already solved it that good.
if not this might work because it worked for me :)
unplug your phone usb, then turn your phone off and then plug the usb back on to the computer and then just wait for the phone to start back up and just wait for about 5 min or so, at first it might say fail to install because the phone havent started up probably yet but it should work after your phone go to it home screen.
if this doesnt work i dont know haha
thing seem to work when you turn it off and turn it back on haha
