You'll need to provide some specific details about what's happening before anyone can tell you how to fix it. What exactly is the problem you're having? Any error messages? We need some specifics,

I just updated my 6100 via USB flashdrive, I assume you've downloaded the pdf from pioneer and followed the directions? Firstly downloading to pc, format card or stick to FAT32, copy to root directory? Mine updated to v1.03 perfectly
