An electronic system includes a network interface connecting the electronic system to a network, a non-volatile memory containing system software, and a CPU connected to the network interface and the non-volatile memory. The CPU discovers new software update components on the network using a universal plug and play (UPnP) protocol, downloads a selected software update component from the new software update components discovered on the network, and updates the non-volatile memory with the downloaded software update component. If the update should fail, a boot loader containing a network stack for a UPnP protocol can be used to reboot the electronic system using a backup software program discovered using the UPnP protocol. When booting, the CPU discovers new update components on the network using the UPnP protocol, downloads a selected update component from the new update components discovered on the network, and updates the non-volatile memory with the downloaded update component.
