Jetson Xavier NX not booting

Hi I flashed my jetson xavier nx in a nano devkit(model: p3450) using sdk manager. According to the sdk manager it was successful. Now I am trying to boot it, however I am not getting anything on the monitor over the hdmi? Is there something I am missing?

Isn’t the best to reflash it in the sdk manager with the adecuate model? Post also the messages that the terminal of the sdk manager gives you.
