  1. Muchas gracias por tu aporte, has tratado de ser lo mas explícito posible, lo que no me queda claro es si también tengo que bajar Magisk e instalarlo, no entiendo. Tengo un S20 ultra y lamentablemente recurriré al root pues me vendieron un celular con un IMEI dañado y por lo tanto después de rootear el dispositivo tendré que reparar yo mismo el IMEI. Disculpa mi inglés. Saludos desde México.

    • Para problemas relacionados con IMEI, debe comunicarse con el centro de servicio más cercano. Es un problema de inserción de hardware. No podemos solucionarlo solo con el software.
