My friend owns a very small business and wants to use a Nexus 7 that a former employee had been using.

It's password locked and he's unable (or unwilling) to contact the old employee. He asked me to reset it.I got it into fastboot mode, then tried to go into recovery mode but it hung on the Google logo.

I did a quick search and found this sometimes happens with older software and requires the unit to be plugged into a computer.The problem is when I plug the device into my laptop, it freezes on the fastboot screen and I need to hold the power down to get it back to the unknown password screen.

I'm reading this may be a result of not having the right Nexus drivers on my computer. I've tried fixing that (though I'm not sure I'm doing it right), but nothing.

Any advice or help whatsoever would be greatly appreciated. Thanks everyone!
