Should be possible, but the following is untested:
- Create generic install media and boot it.
- <Alt>-F3 to get the terminal screen.
- blkid to list the partitions. Memorize your system partition device.
- mkdir /tmp/mnt;mount <Your Device> /tmp/mnt
- cp /flash/KERNEL /tmp/mnt
- cp /flash/SYSTEM /tmp/mnt
- sync
- reboot
Now it is tested! It worked well. Thanks
