The manual system update considers a manual operating system (OS) installation via a console. The progress can be done locally using mass storage devices or using a network connection. The update process described here requires an Ethernet connection of the device to a development PC, either directly or via intranet. Also, a TFTP-Server or HTTP-Server is required on the development PC. There are several, also free, TFTP-Servers and HTTP-Servers online available. Please make sure that the timeout settings of the TFTP-Server are set to 60 seconds at a minimum. 
The installation of target OSes, and Flash-N-Go System and Flash-N-Go Boot should work via console one- or two-liners. All device partitioning, deployment actions should be done by shell scripts executed by the simple command. See Booting Flash-N-Go System for instructions on how to boot into the management system.
