Blackscreen on startup

when trying to install qt6 to jetson I used “sudo systemctl set-default graphical.target” and now cannot boot. It goes into a blackscreen.

How can I reach the data inside the jetson - I dont want to flash my codes :(

I had deespstream 6.3 and jetpack 5. No sd card. I have SSd disk 100 gb on it

Hello @erence,

Have you tried using UART to check the board’s boot messages ?
