    ¿Hay que tener root para instalar esta rom en el Galaxy Nexus?

    • Sathishkumar Varatharajan says:


      Si el dispositivo tendría que tener sus raíces antes de aplicar esta actualización. Descarga la aplicación corrector raíz de la tienda Play Google para comprobar si el dispositivo tiene sus raíces antes.

        No encuentro esa app, mi Galaxy Nexus no es root, por eso pregunto que si hay que ser root o no, si necesita root no la instalaria.

        • Sathishkumar Varatharajan says:

          Hay que erradicar el dispositivo que lo instale. De lo contrario la unidad no recibirá esta actualización.
