Good Evening @Juanaman
Hey sorry you are having a hard time getting a software update on your device. Quick question...Is your device a unlocked device or a carrier device? I ask this because, unfortunately unlocked devices linked to carrier accounts, often time do not receive the software update push. I would recommend getting in touch with 1-800 SAMSUNG, so they can recommend nearby repair centers to get the software update applied to your device.
You can also reach out to your current carrier to further assist with updating your device. Updates come directly through the carriers and are released to the devices that are on their network in waves.
