@A9-2018-M2003: Please be aware that official software downloads can only be achieved via WiFi over your mobile network, or on your home computer using Smart Switch. If you have downloaded the update from a third party source then this is likely to be the reason why the phone is recognizing it as a custom version. With this in mind, you may wish to perform a factory data reset to restore your phone to its default settings, and proceeding with the update via the official channels. Apologies for any inconvenience this may cause you.
