it says “older versions only” for some of the Samsung locks.

Yeah, the full title says
"Samsung Ezon SHS-3321 (only older models or by using firmware roll back)

Here is the link to the awesome work @TamablePumpkin did to crack it

SHS3321 Firmware rollback

Hi All, Finally got my hands on an V1.5 (the one with fitted diodes) SHS3321 that works with a NeXT Implant. Unfortunately the v1.5 unit its self has been damaged, but! I dumped the firmware with a PICkit 3 and flashed it to my original SHS3321 V1.7, and volla!! a door lock that reads my hand. A 30 second write up and the firmware is Here

@ImpulsiveJames

How is the version identified?
