ok so i just got done un-rrod'ing an xbox(replacing x-clamps modding fan cover etc.) and when i started it back up, controllers simply wouldn't connect to it. all i knew to do was press the sink buttons on both the controller and xbox and it would flash simultaneously as usual like it was going to connect and then nothing. the weirdest part was that once i turned off the xbox, i could turn it back on with the controller as usual(holding down xbox button) but once it started up, the controller still wouldn't connect! WTF! then, randomly when i was restarting the xbox trying to figure out what was up, it connected w/o me pressing a single thing and worked perfectly. and now at the point i'm at, controllers won't connect again. help!
