Does any one recoreded screen in onyx devices?

Hello guys

I tried so many programs trying to record screen in my Boox N96 but i field always unfortunately.

The most willing program was Scr screen recorder pro 1.0.5, I could not record it because there were an error massage said something like:
There is an app prevent me to record your screen

Does any one recorded his screen ever with onyx devices?
Please share with us your experience.
