I think it's some kind of device recovery mode designed to recover from "bricked device" situations. It's not the same method that you use when updating via iTu

Aye, it's called Device Firmware Upgrade (or DFU) mode, and it's specifically mentioned in the FBI's request: > "The SIF will be loaded via Device Firmware Upgrade (“DFU”) mode, recovery mode, or other applicable mode available to the FBI."
