Pero el telefono ha muerto, no se enciende ni nada, la bateria estaba cargada al 100% y no entiendo que ha pasado, no entra ni a recovery ni a flashboot mode. Que hago? ufff me estoy preocupando. Gracias.


EDITO: Despues de estar buscando mucho tiempo como solucionar el problema lo he encontrado y ya esta todo bien. Pero sigo queriendo saber que ha pasado al flashearlo. Gracias.
