             status: Downloaded, please reboot router to upgrade it

[minfrin@bellrock.xxx] /system/package/update> /system/reboot 
Reboot, yes? [y/N]: 
y
system will reboot shortly
Received disconnect from UNKNOWN port 65535:11: shutdown/reboot
Disconnected from UNKNOWN port 65535
45 minutes later ethernet is still down and the CAP ac is nowhere to be seen.

Is v7.11.2 a dud for anyone else?

Hi, same problem with 4 hAP mini that we use in class with students, other 3 of the same batch updated without problem. Just after the update they stay in loop, can not be found in winbox nor am I able to restore with netinstall, they keep restarting continuously.
Were you able to solve your problem? Any help or suggestions are welcome.

The only time I've managed to brick a CAP was when the CAP was powered via PoE from a Mikrotik 4011 router.
Updated RoS on router and CAP, but restarted the router while the CAP was updating the firmware.
No PoE from router to CAP while updating = bricked CAP.
Managed to recover via netinstall.
Lesson learned.

Bricked a hAP AC2 during update.

Integrator plugged it into a Wattbox from SNAP AV. Left auto reboot on.

It was the loss of Power during update reboot, that Killed it.
