Anyone know of a way to rescue the lens without sending it back to Olympus?

The body can be recovered by copying firmware to SD card and initiating a firmware flashing. But I wonder three things:

1) Either lenses requires a totally own update device for recovery, forcing you to send it to Olympus.

2) Lenses firmware can be flashed same way as the bodies, by firmware itself informing body that it is specific lens firmware and body does it like it does it for itself.

3) Lenses firmware initiation is different from body, so far unknown.

As we already know, the body itself can read a firmware from the SD card and start flashing itself. You don't need a computer to do it because the camera is the computer to do it, just in a "recovery mode" where it goes when you initiate it via computer itself over USB.

And I think that if the engineers has been smart enough, the situation is like in 2, you have the firmware telling to the recovery mode that update the firmware to lens. If I would have a bricked lens, I would risk for it, but as I don't I am not going to test it

Then that would have a problem, as we know how you can download a firmware from Olympus server without their software and how to rename it for card for flashing, I haven't seen any way to download the lens firmware and how it should be renamed to do downgrade.
