How do I stop my Samsung reboot loop?

Internet connection and battery charge

You should first check if your phone battery charge is above 50%. This ensures that your phone will have sufficient charge to not only download the update but install it as well and not turn off during the procedure. If your phone happens to turn off during the update process then its operating system might get corrupted.
You should also make sure to connect your phone to a good internet connection. As much as possible you should download the software update over a Wi-Fi connection instead of using your mobile data.
Have sufficient storage space available
