My TX3 Mini box has no screw and thus cannot be opened

[albert1]

I bought a TX3 Mini from a local e-commerce website. Now, on many video tutorials, I saw that there are screws underneath the black circular thing. Here, on my box, it is plain plastic with a bump. Thus making it hard to open up from the outside.

Use plastic pry tool (or credit card...) to lift bottom cover up.

Thanks. I think mine is much tighter than the one shown in the video. I am scared to try it myself. Can I boot my Tx3 Mini from a USB thumbdrive?
