do I really need to replace a mother board if image fails

I have an HP EliteBook laptop that was getting a new image. This is a G2 laptop. Anyway I started the laptop image in the Microsoft System Center\software center. Selected the name-G2 - ME firmware - install bios - and googleDriveSync. I then selected and downloaded the ME updater. The firmware finished. Then in the bios I selected fast boot, PXE internal nic, PXE internal IPV4 nic, and under secure boot config I selected UEFI native without CSM then under device settings checked the box that said SATA device mode set to AHCI, VTx is checked  and G2 only then saved it. Then the user grabbed it before I could start the rest as I had to make a call to another user. She took the laptop and now it will not boot to any OS and goes to shut down mode. I was told that this would make a brick out of the laptop? Is there no way to get this laptop back to factory settings without a new motherboard being needed? This is really my question.

Unless a firmware update itself failed, it shouldn't be a brick. But with secure boot and presumably an encrypted disk, the current Password may indeed be unrecoverable. That shouldn't stop you from deploying a new image via USB or PXE though.

I just did an ME (Management Engine) firmware update on my ThinkPad X1 and the process was abundantly clear: Do not interrupt or turn off, because you could damage the system.

So if the ME update was interrupted in process (as I think you suggest) then the motherboard could indeed be damaged.

Thanks to all. The answers were exactly what I thought. I saw the firmware start and figured it would be finished when I came back but apparently she took it before I could see the end. I assumed and that is never good that it did finish as I was not gone that long and assumed it finished before she had time to take it. My fault on the wording. Sorry, but thanks all.
