I am not familiar with that looper, but they are all basically the same. Here is a stupid question, but this had helped a lot of people. 1) Are you using an external power source and not a PS2 plug. If not get one. Voltage means everything.
2) When you put the card in, Whats it returning? Invalid ATR or another message
Its not worth paying someone to do it. Too many changes in the Dave data stream. Make the investment in hardware, and more importantly, make the investment in time to do the research. It is actually not that hard once you do a little research.
Most people i know can barely figure out how to turn on a computer and send email -- let alone figure out reprogramming and figuring out encryption/security techniques as well smart card lingo and technology.
If anyone wants their HU card reprogrammed in la. My buddy does it for $150. All you need is the unit installed. Grab an HU card from ebay and the $150 and you're good as good. 6 months warranty.
