Jetson's OS was corrupted

Hi team,
this post is supposed to follow another topic i posted before of how to install CUDA and openCV that fits to CUDA. after un-installed and re-installed, the OS was corrupted. At this point, I dont think I can solve the problem by myself. I am looking for some personal support such as a way to email the technical team. I am also looking for a way to send my Jetson AGX orin back to NVIDIA for fixing my problem so I need to know the process to send it back. Thank you!

You should rather ask in the Jetson forum:
