Don't worry. In this article, we will introduce some quick ways to fix the problem and proceed with your iOS 17 update. Keep reading.

Why Is Download and Install Button Greyed Out on Your iPhone?

Whenever a new iOS version is available, your iPhone or iPad will prompt you by displaying a red badge in Settings > General > Software Update.

If your device isn't charged or connnected to internet, you won't be given the option to click "Download and Install". In addition, this issue can be caused by insufficient iPhone storage or software gitches on the device.

How to troubleshoot and fix the greyed out Download and Install button on your iPhone? Here are some useful tips:

1. Check Internet Connectivity

The Download and Install button may be grayed out if your iPhone is connected with cellular data or a poor WiFi. Thus, you'd better check your iPhone's internet connection and ensure the device is connected with a strong Wi-Fi network before upgrading to iOS 17. Here's what you need to do:

1.1 Use Wi-Fi Instead of Cellular Data

If your iPhone is on cellular data connection when updating to iOS 16, you should see a notification "This update requires a Wi-Fi network connection to download".

To switch to a Wi-Fi connection, just go to Settings > Wi-Fi and toggle the Wi-Fi on. Once you are connected to a stable Wi-Fi network, go to Software Update and now the Download and Install option should work as normal.

1.2 Turn Off WiFi and Turn It Back On

If you're connected to WiFi but the Download and Install button is still greyed out, poor Wi-Fi connectivity is to blame. You can open the Safari app and open some websites to test the internet. If the internet is not running properly, you can try to turn off WiFi and then turn it back on.

1.3 Disable Wi-Fi Assist

If Wi-Fi Assist is turned on, your iPhone will automatically switch to cellular data when the Wi-Fi network is poor. In this situation, you should go to Settings > Cellular Data > Wi-Fi Assist and turn it off.

1.4 Reset Network Settings

Another workaround is to reset network settings when the Download and Install button is still greyed out. After that, all relevant network settings on your iPhone will be reset to factory defaults.

To do that, open the Settings app and head to "General". Then tap on "Reset > Reset Network Settings". Enter your device's passcode when prompted and confirm the action.

1.5 Try with Another iPhone

If there is still the problem of "Download and Install button grayed out" after resetting network settings, you can try to perform the iOS 16 update on a different iPhone to check if the issue occurs due to the network issue. If the Download and Install button doesn't gray out on that iPhone, there must be some issues with your current device.

2. Check iPhone Storage Space

Large storage will be occupied to install a new iOS update. If there is not enough storage available on your iPhone, the Download and Install button may be grayed out during the iOS 17 update. So another constructive suggestion we offer to you is to check your iPhone storage space. Here're how to do that:

Go to Settings > General > iPhone Storage and you will see the remaining storage on the device. It is recommended to reserve at least 1GB before upgrading.

3. Check Battery Percetage on iPhone

In general, when updating to the latest version of the iOS, the power is one of the key factors that cannot be ignored. If you do not follow the instructions, it may cause great potential damage to your iOS device.

The iPhone power is so important that Apple itself will not allow users to do the iOS 17 update when the device has less than 50% of battery charge remaining.

So before updating, make sure that the device has enough power, or it's better to plug the device directly into the power supply using original Apple lightning cable.

4. Download and Install iOS 17 with iTunes

The steps described above show you basic tricks to get rid of the "Download and Install" button grayed out issue. Some users may still find this issue when they intend to install iOS 17. If so, use iTunes instead.

In some cases, iTunes is a great alternative to update iOS. For example, there is not enough storage space on the iPhone, there is no Wi-Fi around to do the iOS update, etc. Not much to say, let's show you how to use iTunes to download and install iOS 17 on your iPhone.
