Yesterday I had the "No Command Boot Loop" soft brick problem, but got my Nexus back working on Android 4.4 with the Nexus Root Toolkit and several hours of messing around. But now I can't figure out how to get Windows 7 to recognize the Nexus as a device and not as "ADB Interface/Android Composite ADB interface". I just want to be able to transfer some e-books onto the Nexus from my desktop computer. I've tried wugfresh drivers and lots of "device manager" deletions but no success. I even tried hooking the Nexus to my HP laptop but it installed there as an ADB Interface too.... Help!!
