failed system update

tried that my usb desk drive is to wide to fet in the plug in the back of the xbox so i burned it to a desk and it didn't work it just goes straight back to the error screen after a brief attempt to finish the download.

You are going to need to download the microsoft update package onto a usb disk drive and plug it into the console..

You will then boot the console using the power button, the console will recognize the signed update package and proceed to flash the update onto your console

Thanks

I tried that and it did not work. Now what?

Download this systemupdate:
download.microsoft.com/.../SystemUpdate_15574_USB.zip (OFFICIAL MS WEBSITE!!)

This is the systemupdate you need.

After that, follow these steps:

1.) Unrar the download

2.) Copy the $SystemUpdate folder to the root of a CD or USB Stick (The memory stick must be FAT or Fat32 formatted)

3.) Insert the CD or USB Stick into your Xbox 360 console.

4.) You will be automatically prompted to update with a USB stick, with a CD / DVD it should say Mixed Media Disc, power down the 360 and power it on again. You should be ask to update before the 360 boots to the dashboard.

5.) Once the update is complete your Xbox 360 will restart then boot up to the new dashboard. Enjoy!

Hey there, that would be caused by a few things, have you been through all the steps on this page? Troubleshoot console update problems.



In particular, I'm wondering if you've tried removing all accessories (including HDD) How does that go?
