Had this Teensy++ 2.0 here for a while now and this weekend I decided to have a go at downgrading a Nand console but something is not quite right. The Teensy when connected shows a solid Blue LED (not blinking) and when I hit the Activate button it shows up in Windows 7 as a USB Input device, I have followed all of the steps in Coolshrimps downgrade tool (install Python, PySerial, Teensy drivers) but when I get to the Flash Teensy for Nand stage, a cmd window open but it doesn't seem to do anything... (It remains detected as a USB Input device) I have also tried using a USB Hub as recommended without success. I even tried the Teensy.exe file, (I could only find the latest version that supports 3.0) but when I hit the activate there is no change and it remains undetected. I guess my question is if this Teensy is busted, I really don't want to buy a new one if this one just needs a tweak here or there to be detected correctly. Many thanks!!!
