If you think I'm lying, I would kindly ask you to connect via any desk and see for yourself.

Thank you.

Again I press Reset -> Chip Info - > Unseal (stay on 99% to long)

If you think I'm lying,

 You did not provide a picture with unseal steps. When unseal button is pressed there is record in the log "Unseal executed". This record was missing in the pictures.

 Now you did it correctly. Unseal step is logged on the picture. 

Approved for Remote unseal.
