Reflashing only works if you 1. Switch the aPad off2. Switch the aPad on (Do NOT press the center button to start the OS! Just put the switch into the "on" position)3. hold the menu key4. plug in the usb cable5. wait till the device is recognized6. release the menu key.This should always work. If it does not, your device is probably defective. Also remember that the battery may not be empty while flashing, so plug it in while flashing.
