Although iOS 15 beta has the least issues reported compared with another iOS beta, it is still very likely to bring trouble to users. The common issues include iOS Bluetooth problem, iPhone restart loop, cellular problem, etc.

How do I fix the iOS 15, 14 software update failed?

iOS update issues are usually caused by 3 reasons: the network conditions are bad, iPhone has not enough storage or has wrong settings, or the Apple server gives no response.

There is one more thing that needed to be mentioned. You need to install the new iOS as soon as possible, because according to Apple Support if a profile is not installed in 8 minutes after being downloaded, it will be automatically removed by the system. To save your time, you’d better check your Internet conditions by method 1 and then try other solutions to resume the iOS 15, 14 updates.

#1 Check network conditions on iPhone

First, you need to make sure the Internet is available on iPhone. Bad Internet might cause iOS download stuck. Open Safari to see whether you can view any page.

Then, you need to stop other apps using the Internet on iPhone so close other apps like Netflix or Dropbox on iPhone, because they might use the Internet to load videos or files. Restarting iPhone would be a good choice.

Finally, if the network conditions are still not good for a software update. You need to find another Wi-Fi or reset network settings on your iPhone.

Go to iPhone Settings > General > Reset > Reset Network Settings

#2 Make sure enough iPhone storage

The full installation package of iOS 15, 14 are more than 5GB (the profile is just several hundred GB) so you need to prepare 10GB of space on iPhone to download and install the package.
