Learn how to fix the annoying "This application requires iOS 13.4 or later" error and install apps on older iPhones without jailbreaking! If you have an iPhone 6, iPhone 5s, iPhone 6 Plus, or older iPad stuck on iOS 12 or earlier, Apple blocks you from downloading modern apps directly from the App Store.
In this step-by-step tutorial, discover how to force the App Store to download an older compatible version of unsupported apps like Facebook, WhatsApp, YouTube, Netflix, Instagram, and TikTok on any outdated iOS device.
We cover two working methods:
Method 1 (Borrow a Device): Use a friend’s or family member’s newer iPhone to link the app to your Apple ID purchase history so your older device can grab the last supported version.
Method 2 (PC/Mac via iTunes): Use the official iTunes 12.6.5.3 enterprise version with a built-in App Store to claim apps directly from your computer—no second iPhone required! (Includes a quick fix for the "iTunes Library.itl cannot be read" error).

This tutorial explains how to bypass iOS compatibility errors to install apps on older iPhones. By linking an app to an Apple ID via a newer device or a specific version of iTunes, users can force the App Store to offer the last compatible version of an app for their outdated software version without needing to jailbreak the device.
Your old iPhone isn't useless, Apple wants you to think it is.
When you see this app requires iOS 16, don't buy a new phone.
Here's how to force older app versions onto your device.
In this tutorial, I'm working with an iPhone 6.
It's an older model locked to iOS 12, so the App Store won't let you install new apps the
normal way.
But I'm going to show you how to fix that right now.
For this test, I'm installing Facebook on an older iPhone 6.
Even though the App Store says this phone is too outdated, before getting started, let's
verify the software version.
Just open Settings, go to General, then tap About.
Looking right next to Software Version, this iPhone 6 is capped at iOS 12.5.
Let's test Facebook.
When I search for it on the App Store and press Install, you can see the pop-up saying
our iOS version is too old.
There are two ways to fix this error, and here is method number one.
For this trick, we just need a newer iPhone.
You can quickly borrow one from a friend or family member, it only takes about two minutes.
Grab that newer phone, go into the App Store, and temporarily sign out.
Now log in with your old iPhone's Apple ID.
Remember, we're only signing into the App Store, not the main device settings, so none
of their personal data or photos will be mixed up.
This only changes the store account for app purchases, meaning private information like
iCloud data and messages stays completely separate and safe.
Once you're signed in on the new iPhone, go ahead and install Facebook.
As soon as the download starts, it's officially linked to your Apple ID.
Now on this newer phone, search for Facebook in the App Store and tap Get or the Download
button.
If it's already installed, simply tap Update.
As soon as that circle starts spinning, the app is linked to your account, and our job
on this phone is done.
Now that Facebook is registered to your Apple ID, pick up the iPhone 6.
Open the App Store, search for Facebook, and press Install.
What is the difference?
Instead of an error, Apple now asks if you want to download an older compatible version.
Just tap Download to complete the installation.
Now let's test the app.
Head to the home screen and tap the Facebook icon.
As you can see, the older compatible version launches smoothly on this iPhone 6, and you're
ready to log in.
And that's it!
You can use this exact same trick for almost any unsupported app, whether it's YouTube,
WhatsApp, or Netflix.
As long as you claim the app first on a newer device, you can force the last working version
onto your older iOS without jailbreaking.
Now what if you don't have access to a newer iPhone or iPad?
That's where method number two comes in.
Using your computer.
Apple removed the App Store from modern versions of iTunes.
But there's an official enterprise version, iTunes 12.6.5, that still keeps the entire
App Store built right in.
I've left the official download link for this older version of iTunes down in the video
description.
It's completely free to grab, whether you're using Windows or a Mac.
Once the setup file finishes downloading, open it up and run the installer.
Just follow the on-screen prompts, click Finish, and launch the program.
Now when you try to open iTunes, you might see this error.
The file iTunes library cannot be read because it was created by a newer version.
Don't worry, fixing this is super easy.
All you need to do is open Open File Explorer, head into your Music folder, open the iTunes
folder, and simply delete or rename the iTunes library file.
Once that's gone, launch iTunes again, and it will open right up.
Once iTunes opens, look at the top menu bar, and click Account, then tap Sign In.
Enter the credentials for the Apple ID currently logged into your old iPhone, so the store
links directly to your account.
From the navigation bar, click on Apps, then select the App Store section.
Search for Facebook or any unsupported app, and press the Get button.
This officially claims the app on your Apple profile, unlocking the compatible version
on your phone.
And that is how you fix the iOS compatibility error on any older iPhone.
