System Update via USB - Nothing happens after reboot

Please access this link How to get a new Xbox 360 update | Xbox Support as it has another method to update your xbox360

This is happening across two MS xbox controllers and two Rockband 4 controllers. When this happens none of the controllers can connect. If I plug them in via USB they work. Putting the system to sleep doesn't make a difference either. If I hard reboot the
console the problem goes away but comes back after days. It has all of the trappings of a driver issue with the controller system that is causing a memory leak.

I downloaded the last update from this link
www.xbox.com/system-update-usb

Nothing changes.

My dashbourd verision: 2.0.13604.0 so there's a lot of verisions after mine

Thanks for your efforts but they have not solved the problem.

I bought the console around Christmas and since then there was no problem at all. The 'new' update has been out since September so I suppose my console has already had it or had no problem with updating.

Nevertheless I tried to install the updates via USB but nothing happened. Clearing the System Cache did also not do the trick.

Finally I found the way to delete the System Update by pressing 'LB + RB + X + LB + RB + X' in System Settings / Storage. After this I was able to install the update from my USB device. (Actually it was only extracting.) But I'm still getting the "Update
Failed" message...

Any other ideas?

Hi,

I got the same issue resolved by updating via CD.

You should also be able to update via USB, but you gotta format your usb-drive to the FAT32 system first!!!!!

After I inserted the disc with the update(while the error message was displayed), it automatically started to install the update. After that it downloaded another update and updated again. Once that was finished, I was at the homescreen and everything is
working fine now.

I hope I could be of some help.
