Mad catz strike 7 factory reset

[Tjuncc]

One day when i was playing around with my keyboard touch screen i accidentally messed up the touch. Now im trying to sell the keyboard, but they went bankrupt in march 2017 and i cant find anything on how to factory reset the screen so i can sell this nightmare. Any suggestions on what i can do?
I have tried plugging it out completely, hold in mode 3, plug in usb and then plug in the power multiple times with no luck.
