buenas tardes, es mi primer post en foro, y lo hago realmente porque ya no tengo mas idea de que hacer. cuento lo que paso, tenia rom stock decido poner Lineage anda bien pero tenia problemas con las llamadas y camara. Decido ponerle una stock y ahi comienza problemas, se carga una pero no tenia recepcion de señal ( linea ) ni wifi . le flasheo otra y ahi muere , no logro poder sacarlo de bootloarder ... en argentina me cobran $3000Ars ( serian unos 170 dolares aprox ) la verdad que no estoy para pagar eso. espero que puedan darme una mano para revivirlo. Saludos
