K800 cid49 to cid52

Hello,
I have a k800i cid49 red. I try to upgrade to cid52 but I can't. I try with the automatic way (when i connect k800 to xs++ ) nothing. I try to write the right script with setoollite and with xs++ but nothing happens again. What is the problem ?

P.S. I had upgrade cid49 to cid52 succesfully to k610 in the past with xs++ and it was very easy.

I try to write the right script with setoollite and with xs++ but nothing happens again. What is the problem.
