Assistance with the Status Error Code 40A3-0000-0080-0300-8007-045D

I've so far done everything the support groups have given me, and only ended up deleting my profile (was a recommendation) and now cant even retrieve that back. This code has been going on for a few months now, and I can no longer even use the Xbox basically.
I have been given countless reasons for why this error keeps popping up, but with no luck fixing it. If anyone knows a way (I believe it's hard drive oriented) to fix this, it would be much appreciated.

Unable to download update from xbox live

Also not able to get this update on my 360, Error code 416B-0000-0080-0300-8007-045D

 

If you have tried all the steps listed at the link below

support.xbox.com/.../error-code-8007045d

Then please try removing your hard drive and see if you can redownload the tag without it. After it's downloaded you can try putting the hard drive back in again.

Alternately you could get a usb stick and bring it to a friend's house. Download the tag and move it to the stick to bring back to your console.

Good luck.
