Nic Splattstoesser, who repairs common 2018 HomePod issues, demonstrates the process in a video spotted by 9to5Mac.

Restoring the first HomePod, which wasn’t possible before now, involves connecting a custom USB adapter to a hidden debugging port on the bottom of the device. Splattstoesser credits David Syskalczyk and tihmstar with figuring out how to pull it off.
