this might be a dumb question, but have you tried plugging into different usb ports on your laptop?
I use Windows 7 64bit and I have no issues using RSD Lite. I haven't seen anyone ask yet so I will.. How are you accessing the bootloader? And, can you get in the bootloader?
hold up on the d-pad while it's booting up. and yeah i can access it just fine. it's just this one computer. my other computer works every time. i just don't have access to it for a few months.
OK, honestly, I can't even attempt a guess at this. Has to be the comp and not the phone. Just root it without using the computer. I've seen a few threads on here about it.
are you running RSDlite as admin? and what version of it do you have? 4.6 or 4.7
