How do I download an older iOS version

I was having issues with my iPhone dropping wifi calling calls or no audio to callers on the upload via air pods or phone mic. I could hear them. No signal at our house from the tower this feature is a must have. Checked everything: not the internet connection, not the modem, almost brand new Eero router. Only one remaining culprit. I received a replacement phone from Verizon. New phone initiated with auto update turned on and downloaded ios 17.03. Now, the phone recognizes my airpods but not my car, my Bose bluetooth speaker or the digital to analog converter that is connected to my stereo. At first the phone at least recognized the car bluetooth but no key number was generated to pair the devices. Now it's not seeing it at all. Now won't work with ADC either. I've booted and rebooted. All the things. Now what?

You cannot download older versions of iOS. Your device will always download the highest iOS of which it is capable of running.

Hi Matthena,

welcome to the Apple (user-to-user) Community.

Wondering which iPhone model you are using,:

you might want to check if your device is compatible with iOS 13:

iOS 13 and iPadOS are compatible with these devices.

It is always wise to back up your iPhone before updating.

That way you are able to restore data if needed.

If you see more than one software update option available,

choose the one that you want to install."

You’ll need iPhone SE 1st gen, iPhone 6S, iPhone 7, or newer.

iPhone 6 and earlier are not supported on iOS 15.

You will need a Wi-Fi connection, and with no add-on VPN app installed.

Correct.

An iPhone 6, iPhone 6 Plus, or earlier cannot get to iOS 13. At all.

iOS 12 is the end of the line for iPhone 6, and iPhone 6 Plus.

Some older iPhone models can’t get that far.

iPhone SE 2nd gen should be seeking to update to iOS 17.4.1.

You will need a Wi-Fi connection, and with no add-on VPN app installed.

There is no supported means available to select an earlier version.

Your question was how to download to an older iOS version. The short answer is - you cannot. Apple does not support down grading to a lower iOS.

If you have tried using a PC or Mac to reset the iPhone as was listed in the link and that failed, contact Apple.
