Unless they have changed something very recently, you can login as root via ssh on first-run. I double checked /etc/ssh/sshd_config on an armbian install image I had downloaded, and: # Authentication: #LoginGraceTime 2m PermitRootLogin yes #StrictModes yes #MaxAuthTries 6 #MaxSessions 10 PubkeyAuthentication yes <snip> # To disable tunneled clear text passwords, change to no here! #PasswordAuthentication yes #PermitEmptyPasswords no And inside /etc/shadow (default 1234 passwd): root:$y$j9T$SAPCtO/l2ZIj6A2frqTza/$.Z8dP41gzqRHoIS8PvXFn9fghf9rgkGqAWgXVRW4dg6:20234:0:99999:7::: So that should not be an issue here. (and there are keys inside /etc/ssh that I assume can be used at first login, I have never tried) Sounds more like a faulty sd-card that gets mounted read-only, that can cause stuff like this happening. (as mentioned earlier by Igor) Try with a different sd-card (and use armbian-imager instead of balena) and see if the same happens on another card.

I managed to do it thanks

Hello averyone I'm trying to download the multitool.img.xz can someone please help me find it or share a valide link?

The paste armbian URL displays nothing (anymore?) so without any (new) info from you, no-one can help you. AFAIR, 4K via HDMI connector is only recently available (on RK3588, not sure about RK3399), so make sure you can manage various combinations of U-Boot, kernel, rootfs. So sort of act like a developer, als make sure you have a serial console (debug) cable, else you cannot get any step further. Use a 26.2 based U-Boot and 6.19 rockchip64 kernel I would say, then see what happens.

@ag123 thank you for your response. I donated to the project in the past (search my messages, peytote was an awesome guy that helped with some specific SPI issue i had many years ago on a Orange PI i think), i am donating to few open source projects (Like FreeCAD) , will make recurring donations to Armbian for sure. Yeah i am not using any OrangePi with their original OS, no way. I need a more powerful board than OPi Zero 3, will look into the maintained and supported ones here on Armbian. Thanks for your reply.
