[masrsystem]

Hola colegas, posteo esta solucion por que estuve buscando y la solucion era mas extensa o con Octoplus Samsung, la cual no tengo por los momentos. Asi que decidi seguir indagando y di con la solucion.

Deben Flashear con un firmware de Android 9 y que tenga seguridad anterior a Junio 2019.

Aqui les dejo el link del Firmware que yo use.
