RS90 can't transfer file

[RealAquilus]

After installing firmware correctly and working.
https://github.com/OpenDingux/buildroot/actions/runs/4901430509
There is no storage visible where to transfer file.
Tried rndis or ecm with filezilla but didn't work (but maybe am i missing something with these two? like specific port or user or password?)

I was able to log in as "od" using the without password option.
There is no root password which means you cannot log in as root directly.
However you can log in as od then run "sudo -i" which will ask you for od's password, and subsequently log you as root.
