Update from usb drive secure check failure

Hello,

Because of a annoying bug in the Minix, i tried to reinstall the latest firmware through usb drive.
I downloaded the latest firmware and put the zip on a usb drive, put the usb into the Minix, start the Minix into recovery and tried to install the firmware, but the Minix shows a secure check failure.

Does anyone know why i have this mention.

Regards Doser.
