The September release and ARM has arrived

So I have followed the instructions to install EndeavourOS ARM in my Pine64, but no luck :frowning_face:. When I boot my device it does not boot from the SD card.
I have double check the instructions and all seems good, also got no error or warning.
The only difference (and it can be the cause of the issue) is that the tutorial asks to wget directly from root (#), and not with sudo.
So I try a su to get the # prompt, but could not find the password.
At the end I did a sudo wget ... and it seems to works. But again… no booting for my Pine64.
So the question is: How can you get a # prompt from the live UBS ?
