So im running Windows 7 64bit and im trying to re root my nexus 7 (2012) after the 4.3 OTA... Im using Wugz 1.6.6 with the added 4.3 feature and i had to install the drivers so i went with #3 the signed Samsung drivers... so all is well i installed then had to do the same while in boot loader... Now when i put the nexus 7 in while it is in boot loader on my windows machine it is showing as a Universal Serial Bus controller... and this prevents me from updating the driver! I have been stuck for about 3 days no one has any idea! Please suggestions? Im a noob so maybe teamviewer??
