I'm looking at a used 360 slim that cannot apply an update. I am prompted to update when I turn it on, and after following the prompts it returns with error code xxxx-43c5-xxxx-xxxx-000e.
While it seems to be a problem relating to communication with xBox Live, I have also tried updating with the USB and CD methods while not connected via wired/wireless network. Neither alternative methods have worked, as I am not prompted to update after I reboot.
I've confirmed that the USB is Fat32 with the $SystemUpdate folder as the root.
I have cleared the memory cache and also formatted the memory unit.
No idea what else I can try. Maybe get a hard drive for this and try again? What's weird is USB and CD's are not autoplaying, even after selecting those options. I can see the USB in the device list, and it is detecting the overall capacity of the thumb drive. It doesn't need external power or anything like that.
Thanks for any insights!
