xbox failing to update, tried all possibilities posted

Hello I've got an xbox 360 Slim, with a 250-gb hard drive. I keep getting an update error, and I've tried any and all ways to update it (through USB/CD, cleaing the cache and updates on the system, etc.) I don't need to be told to power cycle the system,
and unplug everything and replug everything, or doing the "LB-RB-X-LB-RB-X" trick, or clearing the cache, etc. because I've done that multiple times, trust me I'm very thorough. Any suggestion to do these things are pointless since I obviously attempt the
easiest solutions first and have often repeated them.

Here's the error code I'm getting:

3F4A - 4174 - 1600 - 267F - C000 - 0185

I've deduced the problem to a few possibilities, but have also ruled out the following:

its NOT my internet connection

its NOT to do with the EXTERNAL hard drive (the 250GB one that you can remove)

I've noticed while tinkering around with the dang thing (haven't even really gotten to play it) that the INTERNAL memory of the xbox (the flash memory that I'm guessing is attached to the motherboard) is most probably corrupted. It has a handful of items
on the memory, most of which are corrupted, and can't be deleted. If you try formatting and clearing the system cache, nothing. If you go to them and delete the files manually, they seem to delete but on a restart of the system they're there again.

So what I've found: I'm guessing when attempting to update the system, it wants to put the update onto the flash memory instead of my 250GB hard drive or any other USB flash drive I put into the xbox. Because of that, the update obviously won't load because
the hard drive is completely incapable of reading, writing or even deleting anything.

So my question: Is there a way to bypass the internal memory? and update it onto the 250GB harddrive, which is PLENTY for me since I'm only into a few xbox games anyways. I thought there might be something possible after watching this video:

The only difference between our problems is his internal hard drive says "unformatted" while mine says "1.2GB free" and looks like its about half-used. also, he's using the 4GB xbox 360, I'm using the one with the 250GB hard drive included. Finally, his
way of fixing the xbox worked, whereas obviously it didn't work for me. I wish I could do what this guy did: but its not that easy for me


I really need some help with this, please.

11/25 update failing to download

My xbox is trying to download a 333 megabyte update but keeps failing. I have tried both wireless and wired but still got the same results. I went through all the troubleshooting and it said my xbox was broken but it still works it just won't allow me to
go online because of the broken update.

 

Limbo message auto deleted but have code, but xbox one says invalid code try another code.

I tried all possibilities and I still get wrong code try again??

 

If you've tried everything on the page then perhaps the console is in need of a repair. You could try contacting phone support 1-800-469-9269 in North America or click the link to arrange a call back. support.xbox.com/contact-us
to see what they suggest.

 

Definitely could, but just wondering any other options or ways of "getting around" the internal flash memory thats worked for anyone
