It is "exclusive" because it bypasses the need for an unlock code entirely. Instead of asking the router for permission to use another SIM, the firmware simply doesn't check for permission anymore.

Most commonly, users are seeking out firmware versions ending in ...778 or generic "Standard" WebUI updates that strip away the carrier branding.
