How to update iOS 13

For devices that are using iOS 12 or lower

You can update to iOS 13 directly via OTA by going to Settings -> selecting General Settings -> selecting Software update. After the data checking is completed, download and confirm the update for the device.

Or you can update iOS 13 for devices via your computer with iTunes software and iOS 13 firmware.

For devices using iOS 13 beta

If your device is using the iOS 13 beta (including public and developer), you first need to delete the support version of the test version of the device by visiting Settings -> select General Settings -> choose Configuration and device management -> choose to delete iOS Profile 13 -> then proceed to reboot the device.

Then you proceed to update iOS 13 to the device as usual (the way for devices using iOS 12 or lower).

For jailbroken devices

Jailbroken devices are not allowed to update devices directly using OTA, but must use software on the computer to restore the device. Before upgrading to the new iOS version, the most important thing is that you must back up your data and log out of your iCloud account (if any). Then, you download the iOS 13 firmware and proceed to restore using 3uTools.
