[Q] Camera not working. Please help

---

So I bought a used Gio, everything was fine, until I decodeed it, because it only worked with a Vodafone card and now the camera application won't work. It starts fine, but then it's all black. You can still see the options on the side of the screen and everything. It's like if I would've put my finger in front of the camera. I wen't to a phone service, they sad that it's because of the Cyanogenmod, but then I put back the stock rom, and still, nothing's changed. Please help

i think the problem it is in hardware.
