Nx stuck - Don't reboot

Hi,

I try to make a fresh install.

I put the Nvidia in recovery mode (and remove the jumper between 9 and 10)

The flash fails at 99% (take ssoo long)

I try to boot from different sd. Currenlty, nothing works.

Have you got any idea?

Fred

You can directly try flash.sh instaed of sdkmanger GUI and dump the log.

There are lots of cause for flash fails at 99%. Thus, we cannot tell what is going on by just one comment.
Is your ubuntu host a VM machine?
