Apple has released the public beta for their latest mobile device operating system, iOS 15, at the end of June 2021. Being a beta version, bugs and issues are expected when trying to install this new operating system.

If it’s important for you to get the iOS update, don’t worry. We will guide you through various fixes and solutions so that you can successfully download and install iOS 15 on your iPhone.

Let’s get to it!

1. Make sure you are connected to the Wi-Fi and your battery is charged.

When trying to update your device, make sure that you have at least 50 percent battery juice. Additionally, be in an area where you have a reliable and strong Wi-Fi connection during the entire process.

Download and installation may take some time and any interruption could affect the way the update is unpacked on your phone, especially when you are trying out a beta version.

You can also try charging your phone while trying to update to the latest iOS.

2. No option to download? Your phone might not have the right specifications.

There are two technical requirements that your iPhone needs to have in order for you to be allowed to update in the first place.

One, you’ll need to make sure that the model is new enough and that it’s compatible with iOS 14 or 15. iPhone 5s and older models are no longer supported with Apple’s latest software updates.

Two, you need to have enough storage for it. iOS 14 was roughly 2.2GB in size, so you can expect iOS 15 to require around the same space.

If your iPhone has the right specs, then proceed to the next steps for the other solutions.

3. Quick Fix: Update your iPhone through iTunes or Finder.

Getting the latest mobile operating system through the Settings may not work because of random bugs and issues. Luckily, there are other ways for you to update your iPhone to iOS 15.

You can use iTunes, or Finder on your Mac. These two can just as easily update your device to iOS, and we’re going to show you how. Note that you’ll need to connect your iPhone to a PC or Mac in order for this to work.

Here’s how to update through iTunes:

  • Connect your iPhone into your computer using your Lightning cable.
  • Open iTunes on your computer.
  • On the upper left-hand corner of the app, select the iPhone icon.
  • On the top box under Settings, click Summary.
  • Then, select Check for Update.
  • If iOS 15 is available, click Update.

Here’s how to update through Finder:

  • Connect your iPhone into your Mac using your Lightning cable.
  • Open Finder on your Mac.
  • Once opened, select the iPhone you intend to update in the Finder sidebar.
  • Select General on the button bar.
  • Select Check for Update.
  • If iOS 15 is available, click Update.

Update Your iPhone via finder

Using iTunes or Finder to update your iPhone device may be a bit less convenient, but it’s an adequate alternative that allows you to update your phone should the Settings option not work.

Just remember to keep your iPhone connected to the computer while it downloads and installs the update.

If you still prefer to update the iOS over the air, follow the steps below:

4. Delete the .ipsw file and try again.

As a result of sudden interruptions by connectivity and power issues, your update file may get corrupted.

You also might have gotten the .ipsw file from an unreliable source if you didn’t follow the installation process recommended by Apple.

For whatever reason there is, the old file has to be deleted and replaced with a new uncorrupted one.

Here’s how to do just that:

  • Open the Settings app.
  • Select General, and look for iPhone Storage. Go ahead and select it.
  • Once opened, you will see a list of apps installed on your iPhone. Click on the iOS update software.
  • From here, tap Delete Update.
  • Return to Settings, and head again to General.
  • Select Software Update and download the iOS update again.

It will take a while as the file size is quite large. So again, make sure that your internet connection is stable to prevent any more errors. When the download is finished, your phone will then prompt you to install the system.

6. Use a DFU to restore your iPhone.

In case your iPhone crashes during your update, you can restore the software back to the previous version with a DFU (Device Firmware Update).

You can perform a DFU by connecting your iPhone to a computer and using iTunes or Finder.

This will completely reset your phone, which will wipe out all your media, accounts, and other data. So, it is highly recommended you backup your iPhone before doing this process.

Here’s how you can do a Device Firmware Update:

  • Connect your iPhone device to your computer using a Lightning cable.
  • Once connected:
  • Open iTunes if your computer is a PC or a Mac running Mojave 10.14 or earlier.
  • Open Finder if your Mac is running Catalina 10.15 or newer.
  • If you have an:
  • iPhone 6s or older, press and hold the Home button and power button at the same time.
  • iPhone 7 or newer, press and hold the power button and volume down button at the same time.
  • After holding for 8 seconds, release the power button, but keep holding down the Home button (iPhone 6s or older) or the volume down button (iPhone 7 or newer).
  • Let go of the remaining button when your iPhone name appears on either iTunes or Finder (whichever you opened).
  • A prompt will then tell you if you would like to restore your iPhone. Select the Restore iPhone... button.

Once finished, you should be able to head to your Settings again and update your iPhone to the latest iOS version.

7. Still can’t update? Apple servers might be overloaded.

While downloading your update package, your iPhone connects to Apple’s servers. The servers may get overloaded with requests from hundreds of thousands of users trying to download iOS 15.

If you encounter an error in your update process, your best bet is to try and restart the download, or simply wait until Apple’s servers respond.
