I have a Z2 and just installed a Z3 HD from Garret Toomey. It seemed to work just fine but I would like to verify the Firmware version.

 

I upgraded from a Z1 to a Z2 HD about a year ago and I remember someone telling me the directions but I forgot. Something like putting my two index fingers at the corner of one of the screens.

 

I did a search but no luck.

 

Any help would be great!

 

Thanks!
