@Wolf2000 Alright, I bought a new 16GB Class 10 sd card. I'm going to give it a try. Do I have to use SDFormatter? Because I didn't. Also I'm using a AC/DC Adapter outputing 5V DC 2A throught micro usb port.
@trvnrc It's powering up (3 led) then it's booting and after like 10 seconds it's powering off. (I have a USB converter to see the output of the console if you need)
