I had a WinXP computer, and I installed android SDK, and I was able to connect to my nook via ADB. As it was aging and having fan problem, I bought a new Dell (i5, win7, 4Gb RAM, 500 Gb HD). I installed android SDK, but never tried to ADB my nook. Yesterday I tried it, and whenever I try to connect via IP, or use adb devices, nothing shows up. I tried messing with the firewall, but it was not working at all.
Does anybody have any idea to help me? And also on how to get my firewall back (removed Norton, which I believe is a bloating spyware, and installed avast antivirus, but firewall was not released either, and it gives a 0x80070424 error).
