w910i unlock menu

Hi,

I don't know if this has been posted before and disappeared into the bottom of the forum somewhere, but i have used ultimate unlocker to generate codes for my w910i but i am unable to enter them, I has tried < * * < and nothing happens, then i tried >*<<*<* and i have the service menu up with the option of simlock but it is unselectable, can anyone shed some light on this?

Many thanks

try it with a working sim card in it and i thought D-Ultimate Unlocker unlocks stright away and then the codes are for relock
