Update the device and cellular firmware using XCTU and USB Direct access

You can use XCTU to update the device and cellular firmware. XCTU updates the device firmware to the version you select, and then, if needed, XCTU will attempt to update your cellular firmware. Upgrading the cellular component firmware requires USB Direct, which is accessible using an XBIB-CU-TH development board or from your board design.

WARNING! Version 3100F reorganizes the product's flash memory and upgrades the product to version 31010. You cannot downgrade to a version earlier than 31010 after installing 3100F/31010. You also need to use XCTU version 6.4.2 or later.
