Jetson nano is not rebooting, maybe bricked

I ordered a Jetson Nano and it had a preinstalled Jetpack OS, i wanted to extend the base memory and after performing a restart it is stuck on this page forever, I am new to this. Please help me with this,
Can I

restore it to factory defaults by any hardware reset?

What do you mean extend the base memory? Was this soldered RAM? Or just something like an external drive? Most of the time a Jetson can’t be bricked because it doesn’t have a BIOS (bricking means it can’t be flashed without replacing chips through soldering).

Is this a dev kit? The model with the SD card slot on the module itself does not have eMMC, and uses different flash software than the models where there is an SD card slot on the carrier board.
