The function of rewriting the OS is called "System Update". With this function, you can write new
OS or old OS to IT-G400.
In System Update, since only the system area is rewritten, it does not affect the user area. However,
in preparation for unexpected circumstances, recommend that back up data before updating the
system.
Cautions!
OS update supports OS up version and down version. However, when performing down
version, be sure to perform factory data reset ( refer to " 10 Backup & reset (p.93)” ).
11.1.1 System updates
OS image used for System Update should be stored in internal storage or in microSD card. For both
case, image must be placed on root folder.
