Hi. First time posting on this forum, sorry if I'm too vague or explain my situation incorrectly.
I was given a 13-inch 2018 macbook air running Ventura. In an attempt to downgrade it to Mojave, I wiped the SSD in Recovery Mode– specifically, the part of the SSD that says "APPLE SSD..." instead of "Macintosh HD." I think this was a mistake, because it would not enter Recovery Mode after the wipe, nor could it enter Internet Recovery Mode (attempted to connect, loaded, then displayed an error screen). I attempted to use a bootable USB drive with Mojave installed but it would still attempt to connect to the internet when I did that, and load indefinitely.
I figured this meant that there was a firmware issue of some kind and attempted to revive, then restore the firmware following these guides: https://support.apple.com/en-ca/guide/apple-configurator-mac/apdebea5be51/mac
My second mistake: using the only mac I had on hand at the time– a 13-inch, 2017 Macbook Pro running MacOS 10.14.6. Because it's Mojave, I don't have a modern version of Apple Configurator. Instead I have Version 2.12.1.
Both the revive and restore failed ( The operation couldn't be completed. (AMRestoreErrorDomain error 10 - Failed to handle message type StatusMsg) [AMRestoreErrorDomain – 0xA (10)] ) and now the computer is completely unresponsive. If I hold the power button, the screen does not light up. It does not show its battery charge when I unplug it. When I connect it to my 2017 mac with the USB-C - USB-C cable, it appears under system information > USB as "Apple Mobile Device (Recovery Mode)". Apple Configurator 2 no longer displays it as a box that reads "DFU" – instead it reads "Recovery." I don't know what this means and I can't find anything about it online.

How badly did I screw up? Is there anything I can do to fix this device at home?
Some extra information: I have access to a third mac running Big Sur, but it is so old that it lacks a USB-C cable. I will also have access to a new mac that runs Ventura at the end of this week.

Hello Octopus,


A problem can easily be resolved by bringing it to an expert's attention.

As a first step, I would recommend that you pay a visit to an Apple Genius at an Apple store.

Good luck in the repairs.

richm has it right.

If you can't get it revived yourself, better make an appt. for the genius bar at the nearest brick n mortar Apple Store...

On an Intel Mac the Configurator restore does not reinstall the operating system, and you don't need to use a DFU restore to downgrade the operating system. You can do it either with internet recovery or with a USB installer. What exact error do you get when you try internet recovery?
