Could you tell me the name of the tamagotchi on your V1, I'm not sure which tamagotchis your talking about. But if that's to much work go here and hit connexion and scroll down until you see the character you want and read about him.
Don't worry I had the same problem when I was debugging my tama. Just unscrew it a little bit more and shake a it or pull it out. It just needs a little help, so just jiggle it a little.
