Bom dia Galera. Ando meio que desesperado, pois a uns dias meu celular não quer ligar mais, tento Instalar uma nova room nele e a unica coisa que me deparo são com os erros abaixo.

E quando tento acessar a opção de recovery do aparelho, ele aparece o bonequinho do android com a barriga aberta e o triangulo vermelho. Algumas vezes quando ligo ele, ele fica uns 5 minutos com a tela do google aberta e tenta acessar os sistema com as bolinhas coloridas passando, porém para por ali e não avança mais.
Serei grato a ajuda de todos vocês.

Baixe o app Nexus Root Toolkit no Windows e a última ROM oficial dele, daí faça a instalação normal e veja se funciona, se precisar, o app possui uma função de recuperação.
