Does it ask you to update your controller? Because I have the original controller with no audio jack and it simply will not pair with my Xbox, when I press the sync button it flashes slowly, then blinks for a few seconds and then turns straight off, I have tried just about every method I have seen after weeks of googling my issue, it will work up to where I sign in to which the controller becomes non responsive and it will only connect with usb, when I try to update it the controller disconnects from usb for absolutely no reason at all and reconnects again as soon as the update has started, the usb also did not move in any way so there's no way it unplugs every single time, if anyone has an ideas please let me know
