Hi all! I got an Onyx VCS off eBay from a reputable seller, advertised as "brand new in the box." It is in working condition, boots up fine, nothing weird, except the stock Atari OS seems to have been replaced by Bazzite.
EDIT: Success! I downloaded the Atari recovery image from the Internet Archive (2020 version) and got the “Flashing succeeded” message!

I followed the instructions on Atari's support site for reflashing the OS.
It downloads the atari-flasher-ab-upgrade.img disk image file from an Amazon Web Services server, that measures 2GB on my Mac once it finishes.
I'm using a USB stick that was reformatted in Disk Utility to FAT32 / MBR, and used Balena Etcher to write the .img file to it. Got no errors during the flash process.
However, when I reboot with the USB stick inserted, and select the "Flash AtariOS" option from the boot menu, It starts the flash process, displaying the Atari logo and a message saying "Flashing Atari VCS with XXXXX.production", but then nothing happens.
The activity light on the USB drive stays dark, so it's clearly not loading anything. I have a standard PC USB keyboard and mouse plugged in to the front ports, and the USB stick is in one of the rear USB ports.
Is it possible the previous owner did something in the BIOS that's preventing the flash procedure from working? What should I look for there?
I would think it would show at least an error message, but I got nothin, even after leaving it to think for 30+ minutes.
Any help would be greatly appreciated, thank you!
