Jetson nano super not working and firmware screen is also not getting displayed (not able to make it work)

I followed the instructions in JetPack SDK | NVIDIA Developer

I selected the option :

For other Jetson Orin Nano Developer Kit (fresh unboxed unit or existing unit currently running JetPack 5.x)

Updated the firmware following the instructions : (using micro SD)
🚀 Initial Setup Guide - Jetson Orin Nano - NVIDIA Jetson AI Lab

Till Step - 6 is done and all were fine and no issues

In Step-7 : Reboot and observe firmware update to 36.4.3
After reboot, I don’t see any display from firmware and can’t make it work. I see the GPU fan and other things are running but there is no display after Step-6 is done. Please let me know how to fix this

Hi,

The straightforward method is to prepare the native ubuntu and flash your device using sdk manager.
What is your current UEFI version?

Thanks
