The image I purchased from Dexter was corrupted during an update and I had neglected to make a backup before using it. I downloaded the 2016.01.05_Dexter_Industries_wheezy image from Sourceforge. There were no problems extracting the image from the ‘rar’ file nor imaging it to the microSD card. The GpPiGo booted but when I try to login either via ssh or vnc, I get an authorization failure. I’m trying user:pi and password: robots1234. I’ve also tried the password as: raspberry.
