if you uninstall via lhroot, you must have seen this message

lhroot/system/bin/lhroot

Lines 429 to 440 in 5c916bc

	if [ $installed ]; then
	killlinux
	echo "If dev is not successfully unmounted, please reboot your device or your device will be freezed."
	sleep 1
	echo "I give you 15 seconds to reboot your device if dev is not successfully unmounted."
	sleep 1
	echo "After reboot, you can rerun this script or remove chroot yourself with 'rm -rf /data/<chroot folder>' command"
	sleep 15
	rm -rf $lmount
	else
	echo "No chroot installed"
	fi

If the killlinux command is logging something like this:

umount: can't unmount /dev resource busy

I am telling you to reboot your phone to ensure that all mountpoint is already unmounted. I already give you 15 seconds!
