I upgraded last night…or think I did
This is [robably a stupid question, but how can I tell if it worked?
The flash software ran fine, no errors in the log text and finished with green text stating “image written to device” after about 50 seconds or so.
Does this mean it all worked fine? What’s the easy way to check?
Check for disco mode? 
I think it’s demonstrated in the second video here: Vci-100 1.4 (hd) firmware upgrade
D’oh!
Done
There’s also the firmware upgrade confirmation toggle.
Hi, I completed a button mod and a 1.4 firmware update two months ago, all seamed fine but on the odd occasion when hitting fader fx mode traktor would crap itself. Now it appears the whole controller crashes and losses all connectivity to the pc, i have tried it on two other laptops and used different usb cables but still fails. please help!
