BEFORE RUNNING TO REDDIT FOR HELP, ACTUALLY GO TO THE XBOX SUPPORT! and then try these things if no luck. Do not Just run here making new Posts asking for help without going through proper troubleshooting! that kind of method helps NO ONE.This is just to compile a list of possible problems you can face
1.disc drive not reading game/ loud noise coming from drive (This is the most common issue right now, so far 4-5 cases of this, DO NOT PUT YOUR XBOX VERTICALLY, ONLY HORIZONTALLY)
2.Hanging load screen (If you are stuck at the Xbox logo after updating, DO NOT TURN OFF YOUR CONSOLE.)
3. Ban after using EOU UPDATE ( previously had problems with OS hanging)
4. slow installations if you are having slow disc based installation, do NOT remove disc from console without stopping the install. after stopping the install remove the disc and and completely unplug the console and wait 15 minutes before trying again.

6. cross game party system is is defaulted as off,You have to "Turn on party chat" before joining here is how to do it:
7.I ran into error code 0x80bd0009* after attempting to set up the X1 to output surround audio. I found an Xbox Support twitter thread that explained how to troubleshoot this error and it worked: Press Menu Button, Settings, Display & Sound, ensure HDTV is "select," not "auto." This relaunched my display in 480p, which I easily changed back to 1080p; but the key is that this reset my audio output options. I could now select HDMI audio for 5.1 and DTS, which I couldn't before. Hopefully this helps others with the same error code.
