OK,I have installed eveything like you said z12ub and I even did what you said to get the multimedia studio button to work , and it does. But everytime I try to send anything to my phone , it cant conect (error message) comes up , if I unplug the cable and replug it I can get the address book to come back as well as everything else untill I open multimedia studio and try to send to the phone.
What am I doing wrong to not be able to send my own ringtones?
I even changed my contacts using MTP but can not get multimedia studio to work right,it comes up fine but just wont work right.
