Hi,
How did you point the " update the etc/apt/sources.list.d/nvidia-l4t-apt-source.list file to point to the 35.1 repo"?
I found the solution: Jetpack 5.0.2 with Jetson Linux 35.1 is now live!
Please let me know. I have the same issue as yours.
I can only flash Jetpack 5.0.1 DP and my display still does not work.
