Do you mean the brick code in SX OS? Pretty sure they did remove it. Or at least they say they did. And SX OS is more of a CFW than Hekate is as Hekate is just a loader
I never saw them mention removing it. They claimed to have 'deactivated', which is hogwash. And, taking Nin's XCI function, mixing it with Atmosphere, and adding encryption is not CFW.
