I am sorry I could not get how to move on from that jaguar app.
Do you mean if we install software again so that we can move on from
jaguar app shows?
Could you please guide in detail.
I am not an engineer so would like to have more guide.

Your “Jaguar APP” is the boot logo of your hardware.
So continue with wiki and make a clean fresh CoreELEC install.
