Since a lot of users here root, I figured this would be a good place to ask my question about certain programs. I just rooted for the first time with z4. I am learning a lot off these forums. So far I got the SetCPU. Is there any others worth mentioning that is a must for having root? Is the Titanium BU Pro a must have? So, correct me if I am wrong, but these programs just back up all your contacts and app correct? And when it backs it up, it all saves to the SD card? I am aware of the PRO version being able to "freeze." But I remember reading of a way you can rename the files, I am guessing manually? Thanks.
