Sure it wasn't too complicated really, I can give you the gist of it from memory. 1. Burn Armbian_22.05.0-trunk_Rk3318-box_jammy_current_5.15.35_xfce_desktop to usb drive, plug into usb otg port to boot. 2. Go through basic install routine as usual until you get to armbian desktop 3. You should see your emmc drive as a desktop icon 4. open terminal 5. mount your emmc and important dirs, I don't think I had to mount boot dir ymmv example mount /dev/mmcblk2p1 /mnt mount -t proc proc /mnt/proc mount -t sysfs sys /mnt/sys mount -o bind /dev /mnt/dev mount -t devpts pts /mnt/dev/pts chroot /mnt 6. Use armbian-config to install working kernel (6.6.32) as well as update bootloader. 7. Exit terminal and shut down system, once you no longer get a signal to display unplug usb drive and power cycle to verify bootup and you can freeze with armbian-config once booted up.

I was able to chroot into my existing installation after booting from the Armbian_22.05.0-trunk_Rk3318-box_jammy_current_5.15.35_xfce_desktop image from a usb stick, then i ran armbian-config to install the 6.6.32 kernel and freeze it without issue fwiw.
