How to restore or repair ZimaOS

Hello, I am trying to update the ZimaOS system according to this instruction “Update offline | Zimaspace Docs” but unfortunately it is not working. Can you please advise me what to do or what I am doing wrong? I am attaching a photo. Thank you

Would you explain the whole process you did do specifically?

Exactly this.

Please take a screen record of the whole process and upload here.

I used this procedure, but in my case no update is happening. I have version 1.4.1 installed.

I know the guide you followed. I mean would you reproduce it and record it for us to locate the issue?
