Reinstall all the software for jetson orin nano

I uninstall all the drivers for error and now I want to reflash, but the nvidia jetson orin nano when trying to use de sdk manager disconects from the usb and is not flashing, so this is a real problem for me to work in a clean and new dispo. How I could do the reflash or the reinstallation to the fabric software
