Pioneer 111d - firmware problem



I was flash my pioneer 111d with 8.29 external firmware. Now I want to flash back to original 1.29 firmware. But if I want to do it, take me error “Available target is not found”.
How can I flash back to 1.29?

Sorry for my english… :doh:

I forgot: dvd-rw drive is in an external case USB2.0…


Look into the Pioneer forum, that were already discussed.
