I have a Nexus i9250 rooted with NRT v1.6.1 and every thing was working fine now I can't connect my phone to my computer any more. Using the USB cable it doesn't show in "My Computer". Windows sees it as a New Hardware but I tried letting windows install it but this didn't work. Can I use the toolkit to re-install the drivers? I play around with my phones apps and just installed Titanium backup and went to copy the key is when I failed to gain connection. Is there any thing I might try ? Note: after root I could see the phone with usb debugging "off", with it on "no phone"
