The first picture came out black/white as it s normal, the second one came out good. And then it just stopped making flash and the pictures stopped coming out. After I switch it off and opened the lid for the film. And so before I could close it the pictures i took before came out by them self ( they were obviously not good anymore).
From what you describe, everything sounds normal.
After two shots, the flash will be recharging from the battery which is in the film pack, and this would prevent the camera from taking a further shot until the flash has charged.
As you are aware, the battery for Polaroid cameras is in the film pack. If it took two photographs, then the camera is wiring fine.
If there is a problem, then it is a power issue from the film pack and the film pack is faulty.
