Default [Q] i537 imei 00 after unlock

Hi Guys,

I am stuck. I rooted a i537 and that all went fine. (did with odin and tar files) I tried to unlock it with z3x box, and now the imei is 00. So then i was going to try to write the imei with NS Pro. I follow Ns pro instructions, but the problem is this

NS Pro says change the Uart and USb to PDA, but under *#7284# there is only the uart option so basically NS pro goes through the first steps, but then it tries to locate the phone by usb and it cant see it.

Any help would be greatly appreciated. As i am at witts end with it. I have never been this stuck before. Also its seems every 4.3 phone i try to unlock with z3x box i get a null imei after words and then have to fix with NS Pro.

The phone is not bricked and it still works.
