Glitch with xbox update, not sure what to do ?

Have you tried copying the USB to your hard drive and loading it from there. That's what I would try. I have had trouble with USB sticks loading and saving slowly.

Hey there Lasus! In addition to Draig's post, I would recommend checking out our

Flashing Lights Wizard for more help diagnosing the exact nature of your issue. Let us know if that helps, thanks!

Hello,

If you don't know the e-mail address that you used to set your profile up then you'd need to
contact Microsoft Support Chat.

Click Billing & Memberships > Under Microsoft Account, click Forgot Microsoft AccountUsername then finally click Chat with Microsoft Support.

If for whatever reason you can't access Chat Support, then please contact phone support directly.

As long as you have the gamertag and the information that's associated with the gamertag (name, address, phone number, card number etc.) they should be able to assist you with giving you the e-mail associated with that account.

If you're just looking to reset your password and you know the e-mail associated with your gamertag, you can do so by visit this page here.

On the
startup error solution, the only way to fix error E105 is to factory reset it using the BIND-EJECT method.

If it still does not work, then your console will have to be
serviced by Microsoft.

When you get the 3 red lights, what color is the light on your power brick? If it is anything other than green, try turning off your xbox and then disconnect the power brick from the xbox, wall, and the cable going into the brick. Then plug it all back in
and see if that corrects the issue.

If the light on the power brick is green, send it in for repair. I would recommend including a note that the issue is intermittent if you do decide to send it in for repair. By the way, it is cheaper to submit your repair online rather than calling xbox
support.
