Use this menu to update the firmware on Passport or view the currently installed version.
Update Passport's firmware from a
.bin file on a microSD card. Passport only allows you to upgrade to a firmware version that is the same or newer. There is no way to downgrade Passport's firmware. By default, Passport can only install firmware signed by 2-of-4 Foundation Devices keys. Expert users can, however, add their own public key to Passport and sign their own firmware.
View the current firmware version and boot counter.
The boot counter is the total number of times Passport has been powered on. While not currently used for anything, an expert user can make note of this number as an extra security check.
