Hey last night I fastbooted because my phone was acting up really bad. Now I'm looking every where for a 4.2.1 exploit but I can't find a working one. I updated all the Moto drivers, and I have USB debugging enabled, as well as open source apps. Just one main question: 1) Since I fastbooted to 4.1.2, can I fastboot to an earlier firmware? Say, ICS? Or 4.1.x?
