When I got my Google Galaxy Nexus and was going to root it, it had 4.1, then came 4.2 and just when I got ready to go for it we get 4.2.1. I have downloaded Samsung_USB_Driver_for_Mobile_Phones_v1.5.14.0 and NRT_v1.6.0.sfx, Is this the way to go or should I wait for the software to catch-up with the updates?
