RESOLVED: After reading https://community.onion.io/topic/1762/omega2-flash-omega2p-v0-1-10-b162-bin-break, I copied the firmware to a 1 GB flash drive I had in a drawer (instead of the 64 GB one I keep with my computer). It is now going through the restore process as expected. @Global-Moderators you guys really need to pull firmware builds that are known to cause bricking.
