I think I've broken the ATXRaspi [loose soldering]

[bios]

 I soldered the headers and 4 USB port connections to the board (without the 2 anchors usb)
then as the video says, I connected all the wiring, installed the script, and did the test, everything worked properly.
Once I finished the test, I decided to turn off the raspberry by the new button way, once  the raspberry turned off, I disconnected the power supply  micro usb from the ATXRaspi, and then all other wiring port, I went to weld the USB anchors, but on returning to turn on the raspberry again the button does not work any more.

I think the mistake I had was that I didn't uninstalled the script as it says at the end of the video or I did something that  broke something when I soldered the 2  USB anchors.

I'm using Raspberry 2
ATXRaspi 2.6
Raspbian Latest

So my questions are, is broken?, Is there any chance of making it working again, what can I do?

Thanks in advance and greetings.

You should not need to uninstall the script unless you plan to stop using the ATXRaspi on that Pi.
Reducing the problem, from your description something happened during your soldering, it was working before, then soldering...., then its not working. Can you check your soldering, connections?

This is how the back of the board looks after the soldering of anchors, can not see anything strange or different from the first time, only the anchors soldered.
when I say that does not work I mean that nothing works  even the LED of the button doesent work anymore.

It's out of focus slightly so I cannot really tell if anything is shorted, but the anchors are not connected to anything.
Either way I cannot guess what happened there. I would start debugging for shorts - use a continuity meter between the input/output and GND.
Then plug the uUSB input and check that there is ~5v between input (the "+" pin next to uUSB) and GND.
If you just power the board and press the button, the board should power up the button LED and provide 5V on the output ("+" on the output side), check that has 5v also, etc.

I just fix it, appears that 1 or 2 of the button header welds in the board were loose.

Thanks for help.
