I toggled display off with Mazda Connect, now what?

[hotelzulu]

Punching myself in the face, I tapped on the "Display Toggle" script using MZD-CONNECT-1 to access terminal mode with v74. And now my display is black and I can't get it back. I've googled around quite a bit and can't figure out any way out of this. Does anyone have a solution? (or is it a trip to the dealer?)

Thanks in advance,

Paul

I actually solved this myself by re-updating the 74.00.324 image. I had to shine a flashlight on the display at an angle to take the place of the backlight. It allowed me to see the display and then enter 99 on the diag menu using the rotary main knob. Screen came back to life after the re-flash. What a relief!

Actually as it turns out I spoke too soon. Sure the display came back on when I re-installed the firmware. But afterwards, when the car was locked up and after 5 minutes, the screen is off. So I'm going to just buy a used KN3L-66-9C0 CMU and install it! If that works it will only be a $90 mistake. (back to punching myself in the head).
