how to update from iOs 12.5 to iOs 13.4

Hey there,

Please let us know what is your iPhone model?

If you have iPhone 6/6plus , this device can’t be able to get update anymore, the last iOS version for this device is iOS 12.5.7!

You can't. An iPhone on any version of 12.5 will always be a 5s, 6, or 6 Plus, none of which are capable of 13 or above.
