Xbox 360 Not Updated?

My Xbox 360 does not want to update. First they show me the error code xxxx-xxxx-xx8x-xxxx-8007-2746 on which Google spit out this page

https://support.xbox.com/...-8007-2746

At the step with update via USB it was once (she extracted) but then this message.

Am now at a loss what to do next Maybe you can help yes

Try restarting the console so that it is connected to the internet and then it should work smoothly.

I know from my own experience, but with my Xbox one

Did not work already had 3 lists on the microsoft support page gone through the support can't help me…
