ok...so i proceed normally like for w850i until he ask me for this upgrade right?
i connect the phone to SE tool but he don't ask me for nothing diferent...and the option "Change CID to" is disable.... :S
EDIT: Ok its DONE!!! the mistake is that i need to do the change of Cid with XS++ and not with SETool, but thays ok....i made it ! Thanks again:)
