“I was trying to update my iPhone 12 to latest iOS 15 version but the download and install option in 'software update' was greyed out. How can I fix this?”
Upgrading iPhone to the latest iOS 15 brings many newest features and security improvements. However, some users have experienced issue with the Download and Install button grayed out and they're unable to do the iOS 15 update. Before getting yourself into a complete flap, the easy and useful tips below will get you out of the crap.
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 connectivity and ensure the device is connected with a strong Wi-Fi network before upgrading to iOS 15. Here's what you need to do:
If your iPhone is on cellular connection when upgrading to iOS 15, 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 Wi-Fi network, go to Software Update and now the Download and Install option should work as normal.
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.
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 shouldgo to Settings > Cellular Data > Wi-Fi Assist and turn it off.
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". Thentap on "Reset > Reset Network Settings". Enter your device's passcode when prompted and confirm the action.
If there is still the problem of "iOS 15 Download and Install button grayed out" after resetting network settings, you can try to perform the iOS 15 update on a different iPhone to check if the issue occurs due to the network issue.
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 15 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.
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 15 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.
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 15. If so, use iTunes instead.
