[Solved] Restart Xiaomi Mi TV Stick - logo constantly appears when turning on

Hello.

How can I restart Xiaomi Mi TV Stick?
The problem is that after turning it on, the logo appears every now and then, then disappears and reappears over and over again :/

Disconnect, hold BACK + OK on the remote control, reconnect while still holding these buttons.

I think I`ve done this before, but I`ll try again and report back

I did that too and still nothing. The Mi logo appears and then a red screen. Well, I reset it again in the same way and this time the Mi ok logo again, this time a blue screen. And the third time, this time an orange screen. Well, I don’t know what to do anymore... So far everything was working until I had to disconnect the stick and hide it from my kid for 2 weeks because he didn’t want to do his homework and just kept watching movies on Netflix... and now Christmas is coming and I’m left with no entertainment. ...
Is there any other way?

I returned it under warranty.
