Try this. I am not sure if the 990 has the same bootloader as a 890, or the same process, but its worth trying. This is the process on the 890 so hopefully the same:
To enter Bootloader mode, remove battery. With battery removed, press and hold Power On and Mute (keep holding both down). Reinsert battery and depress buttons. You will get a message that the files are not found and to connect to a PC and download. Before doing this, remove battery and reinsert. It should find your files.
Just saw this! Charging the remote again now, was just about to send it to the US, Would be fantastic if this works :-) To be continued...
