Lighthome problem GT1 Ultimate

FCV

Goodnight. I recently purchased a second-hand GT1 Ultimate box. The seller didn't mention any problems, he just said that he restored the box to factory settings. After the initial configuration I came across the lighthome problem, quite common here on the forum. I need some guidance on what to do and how to do it. Thank you in advance for any attention you can give to my issue.

My box is a GT1 Ultimate - Android version 7.1.2

Can anyone give me some guidance? I looked at the different posts on the subject, and either no response was given to the user or the links are already inactive.
