How do you TOTALLY RESET a Virus TI?

[Pighood]

I mean wipe its memory clean.

I can't presently downgrade from 2.7.5, and the octave transpose lights no longer respond to ANY upgrade/downgrade attempt...meaning the USB BIOS mode is going untriggered by my Mac.

Virus Control loads fine in Logic, but does not communicate/link up with the TI, so I can't hear the sounds in the Virus Control menu.

You could try to power up your Virus while holding the exit button.
This way you manually boot your Virus into update mode.

Tried this many times...and since my Virus can't downgrade, the process never gets to the point where the transpose LEDs light up, confirming a COMPLETE update process.

So...I need a REAL FULL reset.
