> “Even if that device does reboot for any number of reasons, memory maintenance or the power is lost or whatever, the AFU state is not lost. This is the true magic behind the GrayKey Preserve and the Evidence Preservation Mode function.”

Based on this, it seems more likely that this involves exploiting the device to retrieve the underlying keybags present in AFU mode and store them, rather than manipulating the actual feature of automatic reboots. Then the device can be exploited again in BFU mode but with the prior keybag to decrypt everything.

It sounds like this feature is being used to exploit and extract keys from devices without a warrant (or in advance of getting one), which seems dubious to me.
