Hi. First post here. Never jailbroken a Kindle before but I just bought my wife a new one to replace her Paperwhite 5 so thought I’d jailbreak the old one and have a play. I’m aware that this is being deprecated from May 20th so I deregistered it from her account then went on kindle modding and it says on there to jailbreak this device it must be registered. Tried registering and it failed.

Is this game over or is there any way around it?
