PW5 Help with Jailbreaking - Can't Access Demo Mode

Hello everyone,

unfortunately, I can't access the demo mode. Can someone please tell me what I am doing wrong?

According to my Paperwhite's device info I have a 11th generation Paperwhite with firmware version 5.14.2

I already performed a reset via the settings. After resetting, I am asked for the language. I select "English" and then "United Kingdom". Then I am asked to choose the "set up on this kindle" or "set up with your phone". I choose "set up on this Kindle" and press "set up later" as well as "Finish Later".

Then I skip the introduction with "Next", "Next" and "Done".

Above in the search bar I enter ";enter_demo" of course without ""
I confirm this with the right arrow button in the search bar.

I then hold down my power button and press "restart". Unfortunately, I still can't get into demo mode. What am I doing wrong?
