Boot stuck at usb detection

I have a xavier nx and was running fine until I had to install opencv by building it

It took hours and at the end it asked me to reboot. During reboot, in the screen with the nvidia logo it said it was updating stuff

I wonder if it did an apt upgrade by itself, which I know it just messes up the whole system and I had tried to disable it altogether

Now it will not go past the usb detection. Any ideas of how to recover it without having to reflash? Thanks

Put the serial console log here.

Thanks I just reflashed
