Multiplayer isn’t working no matter what I do. Why?

I tried all of that stuff you told me to do and it still isn’t working. I’m confused and aggravated, I need help on what to do. The same message keeps popping up no matter what.

Any solution to this that doesn't require paying for an expensive repair?

Error code, 8007 045D, is indeed pointing to an issue with a corrupted storage device.

Before sending your console in for repair, maybe you might consider to format the internal flash memory, as long as this unit doesn't show as "unformatted".

If you consider this as an option, don't forget to move contents you wish to save to a different storage device.

The ones you've downloaded can be reacquired later from your download history, so just the disc games.

Hey again Sly! Thanks for all that information you provided! That was very helpful in figuring out what's going on.

The 4gb of internal memory that you're referring to is just flash memory. It comes standard with the unit type that you purchased and that's where the issue seems to lie. It appears that the memory is on the way out and is corrupted. When you try to install
the update (by downloading it or by USB drive) it automatically tries to install the update to the 4gb flash memory (since it's the default storage device). Unfortunately, since the memory is corrupted, the update gives you an error code.

The best course of action would be to send the console in for a repair. You can head over to the
Online Service Center to get that started or you can use the
Contact Us page to set up a support call with a repair specialist who can assist you.

Be sure to remove any games, hard drives (not your 4gb internal flash memory, that can't be removed), USB drives, etc from your console before sending it in. Once your console has been repaired you should be able to install the update without any issues.

Let us know how that goes as well as if you have any questions. =)
