Again I answer you with a response you dont deserve. Device is busy means that you have:

Either a program running inside the chroot that you have not terminated - "ps aux" will show you which ones, I find it is often dbus. Terminate that program by typing "kill <PID of process>".

Or there is another sub-folder that linux has mounted within your chroot without you knowing. Typing "mount" will show you what. I find usually /dev/pts is the culprit. Than "umount <location>" (or whatever fuse is) to unmount your folder step by step backing up each time.
Even with telling him to RTFM (in Chinese) hasn't gotten him to learn about:
umount -l
