Why is this happen?

So I bought UFI Box around two months ago, have never been able to use it since I bought it cause I've been busy. Just do some software & driver installs and do some run test.
Then just today, my friend's phone got his screen locked, then I tried to use the box for the first time, and then that's whats shows up on the start up. I can enter the menu, but it's not detecting anything when I tried to connect the phones on EDL mode, it got detected by windows but not the UFI. It only shows up on android tool box, no something like that on the other two software.
So, how did this happen? and what's should I do to fix this?
Thank you in advance
Sorry for the messy description.
