I have a problem in Minecraft version 1.8 and want to unlock a villager who has blocked every item he buys or sells. How am I supposed to do that.

Does anyone know how to do it?

Only works with commands

This is not possible.

The chance that it will be banned completely is very small, but if you do, then - like you now - you are unlucky.
