Black Hat Hack3r does not work

First of all: thank you all so much for answering me!

I tried to run the code RogueM suggested, this is the result:
//
Hardware Revision : a01041Revision match: Pi 2 Model B Rev 1.1Linux raspberrypi 4.4.13-v7+ #894 SMP Mon Jun 13 13:13:27 BST 2016 armv7l GNU/Linux

Here you can see pictures of the setup and of the soldering, maybe you can see something I can't.

thank you very much! :)
