Missing line in the settings tab

I had a look on several Youtube videos on how to root the K1. These vidos start with showing the settings tab with a line “Root account information”.
On my K1 there is no such line, so I couldn’t (eventually) continue with the root process.
What is wrong with my printer, or how can I persuade the printer to show that line?

Answer to myself:
Problem solved. I had to update to the newest version of the firmware.
K1 rooted successfully now.
