Status Code "4497 - 0000 - 3080 - 0300 - D000 - 0185" when connect to xbox live (xbox360...

When I turn on my xbox 360 I get a message that an update is needed. But when I try to update it I get an "Update Failed" message that says "Can't download the Update. To test your connection, open System Settings and select Network Settings, Test Xbox Live
Connection." with a Status Code "4497 - 0000 - 3080 - 0300 - D000 - 0185". When I test my connection, everything is fine except my connection to Xbox Live.

I have tried restarting my xbox and my modem, I have tried clearing my system cache, I have started my xbox while holding the sync button to clear failed downloads, I have highlighted my storage drive and pressed LB RB X LB RB X and I have tried installing
the update from a USB but nothing has worked. It still keeps telling me that I need the update but then it fails when I try.

I finally tried to do a factory reset by using the Format option, but when it finishes my games and profiles are still on the xbox so it clearly didn't work.

I was told the previous thread by JavanGreen is locked and a new thread is required. So, copy above from JavanGreen with addition info.

- I can sign in the xbox account and view my xbox profile

- I have checked my security info and all are fine.

- only 38M is available for my console and some files are marked as damaged.

- press reformat, nothing happens

- delete files, appear again

"4497 - 0000 - 3080 - 0300 - D000 - 0185". what it means?

Why I can restore factory setup?
