Rock64 bricked after upgrade

No, it means it can't find bash. Is /bin/bash the path to your Armbian bash?

Sorry. I'm wrong, yes. You'll need another device of the same architecture to properly chroot into it. Or you can use qemu-arm:

Code:

# This provides the qemu-arm-static binary
apt-get install qemu-user-static

# Mount my target filesystem on /mnt
mount -o loop fs.img /mnt

# Copy the static ARM binary that provides emulation
cp $(which qemu-arm-static) /mnt/usr/bin
# Or, more simply: cp /usr/bin/qemu-arm-static /mnt/usr/bin

# Finally chroot into /mnt, then run 'qemu-arm-static bash'
# This chroots; runs the emulator; and the emulator runs bash
chroot /mnt qemu-arm-static /bin/bash

You might also try copying any configuration changes you've made to you x86 install, make a fresh SD, and then copy over your configuration changes.
