A couple days ago, Apple just launched the new iOS 12 Beta. According to the testimonials on forums, the update to the new version causes many problems. Some of them fail to download or install iOS 12. In this article, we explain how to fix an error occurred when install iOS 12 Beta in iPhone X, 8/8 Plus, 7/7 Plus, 6s/6s Plus , 6/6 Plus, SE, 5s, iPad Pro, iPad Air 2/ Air, iPad mini 4/3/2 or iPod Touch 6.
The first possible solution is to do a forced restart on your device. This helps to force all processes on the phone to shut down and start running again. So, if it’s a problem in a timely manner, it will be solved after the hard reset.
To restart the iPhone, press and hold the Home button and Power/Standby button simultaneously for 10 seconds. For iPhone 7/7 Plus, press the Power/Standby button and the Volume Down button until the Apple logo appears.
If you can not download the iOS update file due to insufficient space, you need to delete files from the device manually.
The very first step is to check the storage space available on your iPhone and the space occupied by each of your applications. To do this, go to your Settings> General> iPhone Storage and you can finally find out how much space you have left. For applications, you will have to go to “Manage Storage”. You will then have access to all your applications and the space they occupy.
Now that you know the space available on your iPhone, you will have to sort through your applications to make room. Once in Settings> General> iPhone Storage> Manage Storage, you will see that some applications take up a lot of space and there are certainly some that you do not use anymore. If so, click on it and delete the useless applications!
If the iOS verification failed because you are not connected to the internet or you can not install the iOS 12 update file because an error occurred while preparing or checking for the update from Apple. In this case, make sure to connect to an active and stable network connection first.
Go to Settings> General> iPhone Storage. Type Manage Storage on the Storage tab. Then touch the iOS 12 software > Delete update.
