I had RSA ADB fingerprint issues, worked for ages then stopped working, went through every forum post and nothing worked, then found this post.... stackoverflow.com/questions/31638582/android-adb-devices-unauthorized[/url]
opening a cmd prompt in this location C:\Users\<your user name>\AppData\Local\Android\sdk\platform-tools and running adb from here and it worked straight from the off.
i've spent 2 nights working on this, so if it helps anyone
