I have an OS2 which had firmware V77. Attempted update fails via web interface. Downloaded V81, and followed instructions to plug into computer, and get to bootloader mode. Pasted V81 to bootloader, and red/green LED blinks as expected, copying file to OS2. My problem is that it fails to finish copying file, and bootloader disappears. LED turns solid red, and not solid green, as it should. Unplug and replug OS2, and no LED lights at all. If I press the button, it will go back into bootloader mode, and again, the entire V81 file fails to copy, resulting in a steady red LED for about a minute, then LED stops completely. Any suggestions are appreciated.
