If you read the thread wherein drgeoff mentioned that OBi 200 and 202 devices have different methods of accessing the local web server, and you were able to get to the device's web page, and you tried to upload the firmware, but it failed during the upload, then the device has bad flash memory and it's toast. If you couldn't get to the web page, it means either you didn't follow the correct procedure to get to the web page, or your device is completely fried. There are no user-serviceable parts inside.
