Default [Q] GT-N8010 (wifi) GPS not working (SOLVED)

Hello there.
My GPS stop working a few days ago. There's any way to test the GPS?
I tried many GPS test apps, but all of them said "GPS signal not available".
I'm using Gnabo_v4, but when in stock rom it stoped.

Edit: solved opening the device and plugging again the gps. When I sent my device to technical assistance they unplugged mine gps and forgot it. Now my warrant is over m so I decided to follow a YouTube video that shows how to open it.
