This forum is NOT FOR USER questions or problems but DEVELOPER.
If your channel import/export does not work anymore (are yuo sure? try again and again, should work), then here is no chance you get your firmware back.
You could try to make an Exlink cable and get to console... But probably it is dissabled by latest firmware.
