Anyone tried to downgrade CID with Ultimate Unlocker?

I wish to downgrade CID on my K550 CID 53 phone to CID 52, so can I do that without unlock or better question: the price includes unlock and CID downgrade?

Did anyone tried this service and mentioned feature?

EDIT Is it a problem if it is branded? I have a Vodafone firmware in it.

I'd like to know that,too,because my K770 is CID53

And I wonna now what about crossflashed phones-what phone I must pick (original or crossflash)

I did and it was fast/great, I think you should choose the model you flashed into or if that doesn't work then into the original. I don't think it depends on which model it is, but which same hardware based phone it is.
Sorry for my lang.

have you attempted to use any free tools after your downgrade? eg xs++3.1?

also did you have to buy a supreme credit?

Paid for 1 normal log downgraded from 53 to 52 best program ever had no probs with it and yes tryed xs+3.1 and is working fine with it

I would like to know, cause K810 is CID53......
