Seems that this firmware image does not contain a rooted Android partition.
I've confirmed after multiple tries that the Android is not rooted and does not have Magisk Manager "pre-installed" per instructions here -

I'm very sad since the latest stock Planet Kali image (which does have rooted Android option with MM) seems to break (unbootable) when doing an
apt upgrade after flashing. Even after removing vim-tiny...

Can we get a rooted Android partition image?

Thank you thank you!
