K so I did the flash drive yesterday didn't work. I did it today and it worked, but now my xbox has a different error code and won't recieve game updates or app updates. I have never had this problem til yesterday!

Okay I will try this as soon as I can thank you for your help, I didn't know there had been a system update the only thing it has prompted me or is game updates that I can't get as my account won't connect to Xbox live, though today when I turned it on it
booted up my Xbox and as soon as home loaded it said disconnected from Xbox live :/

I am having the same issue today Derrtygotgame. Was fine yesterday after Xbox Live came back up. Was playing The Master Chief Collection fine today and then it just booted me out and keeps saying I need to connect to Xbox Live even though I am.

The only solution is to uninstall and re-install every backwards compatible game on my Xbox Ones. This is disgusting and I'm getting sick of these constant Xbox Live issues. I was playing all of these games yesterday. Now none of my BC games can be booted
up online? I had a few hours to play today. Now that will be spent redownloading games that were already downloaded. If this type of stuff happened once a year it would be fine. It happens monthly almost weekly at this point. How did Microsoft believe the
original Xbox One should always be connected to Xbox Live, when Xbox Live goes down every other week or the new updates never function properly?
