From my own experience with different L4T I always had to configure the user manually on first boot.

It could be your previous rootfs has some user set already but you forgot.

For example, ran l4t_create_default_user.sh already.

I’m assuming this is the exact opposite of what the question sounds like.

If you are reading any documents which say that there is a default login, then the documents are years out of date. There is no default login. Many years back (during L4T R28.x? maybe as early as R24.x) California added a law about shipping computers with default name/password, and so this had to be changed to first boot setup.

You should be able to run this command on the host PC if you want a default password and name (one you’ve created). Just run this once and all flashes from then on have that name/pass:
sudo ./tools/l4t_create_default_user.sh
