Si aun tienes problemas sigue las siguentes instruciones: 1.Primero baja el update  y grabalo al USB. Puedes descargalo aqui: Desgarga Luego apaga todo los settings de network en tu xbox desconectado de la red de cable y wifi. Luego sigue estos pasos:   Borrar el system cache: 2.Guide button on your controller, go to Settings, and select System Settings. Select Storage or Memory.
 Highlight any storage device, and then press Y on your controller. (It doesn't matter which storage device you select; the cache will be cleared for all storage devices.) Select Clear System Cache.

2.Then we will delete one other temporary file. Can you select the storage device and find the system items folder? Do you see marketplace system data here? Delete that

3.To delete the system update, please press the Guide Button (the large silver button with the green X), then select 'settings' (on the right). From there you will select 'system settings', and then 'storage'. Please highlight any storage device (it does not matter if it's the hard drive or the USB flash drive) then press the following button sequence quickly on your controller: Left bumper, right bumper, X button, left bumper, right bumper, X Button. When prompted, go ahead and click 'A' for 'yes'. The console will restart: after it does. Let's try to update while the console is not connected to the internet. We can first try it with that USB update.
