What size Hex for JB4 enclosure?
 

I’m in the middle of installing my JB4 and I’m trying to open up the JB4 enclosure to instale https://showbox.bio/ https://tutuapp.uno/ https://vidmate.cool/ the mobile connect but I can not find any hex size to go into the screw heads to open it up. Any help would greatly be appreciated! I’ve tried every hex key I have and not go in... either too big or too small.
