These are the instructions I tried to follow to erase:
1- Press and hold the push button on the netduino for the whole procedure (leave it pushed at all times)
2- Plug the USB to the computer
3- You should see the combobox in MFDeploy.exe contain your usb port
4- Press as fast as you can the "erase" button on MFDeploy.exe
5- You can now release the push button on the netduino
I am running XP SP3. It gets stuck on
