erom update on k530i

hi all

is there a way to update the erom (boot) version on k530i from R3A016 to R3A022
i know that i will update cid52 to 53

i must do this update so Sony Ericsson Service Software (EMMA) will be able to let me update my K530i

u cant use emma becuse u need a ac and only sevice shops have it u can try the sony ericsson update service that will change it to cid 53

i tried the update service and its says that there is no update neded

why do u need a cid 53 phone ?
