Olá
Obrigado pela sua resposta. Eu já tentei repor, muito a meu pesar não ajudou. Depois de carregar o tablet nebylo todo o meu software e agora eu não posso mesmo criar uma Conta do Google, porque WiFi não está funcionando.
Há esperança que ajuda uma atualização de firmware, mas não consigo encontrá-lo.
