#2 iPhone Won't Update to iOS 12? Why not Using iTunes?

It is common knowledge that OTA (Over the Air) updates are usually easier and more convenient to perform, and most iPhone users, therefore, prefer to upgrade using OTA. However, OTA installations often lead to "iPhone won't update to iOS 12" issue, either due to weak Wi-Fi network/internet connection signals during the update, or accessing the Apple servers when they are busy due to a large number of users trying to upgrade at the same time, and so on. Consequently, in such cases, we would recommend updating manually using iTunes. The process is equally easy and fast.

Here are the steps for updating to iOS 12 using iTunes:

Step 1. Open iTunes on your computer and plug your iPhone in using your cable. (Make sure you have the latest version of iTunes installed on your PC.)

Step 2. Click the "iPhone" button just at the top of the window to select your device. Then click on "Summary" > "Check for Update."

Step 3. Click "Download and Update" to confirm you want to update your iPhone.

Step 4. Enter your password if asked. Then, your device will be successfully updated to the iOS 12.

#3 Charge Your iPhone Before Updating to iOS 12

It is very important to ensure that your iPhone or iPad has sufficient power (over 50%) charge level before attempting to upgrade. If not, make sure you connect your device into the charger when you want to upgrade to iOS 12. This is because backups take a while, and you don't want your battery to run out of juice during the process.

#4 Factory Reset Your iPhone

Have you tried all the above tips, and you're still having issues updating to iOS 12? Then try doing a factory reset. This will wipe your device completely, so it is very important to do a backup before resetting factory settings.

To reset, go to Settings > General > Reset>Reset All Content and Settings.
