lo primero que hay que tener muy en cuenta es respetar el ARB (anti-roolback) del software para evitar un hardbrick,
este downgrade lo hice porque la Octoplus no desbloquea este equipo estando en la 8.0, tenemos que degradarlo a la 7.0, siempre respetando la versión de ARB que posea.
puedes degradar de la 20g a la 11g sin problemas, los dos softwares son ARB0-1
vean el error al intentar desbloquear con Octoplus
