Trying to install the latest iOS 15.4 update, but it’s taking forever and your iPhone gets stuck on the Preparing Update screen?
What to Do When My iPhone Is Stuck on Preparing Update?
Step 1. Inspect Your Storage Space
Storage is always the first concern to installing any updates. If you are upgrading from iOS 15.1 to 15.4, then 252 MB's space would suffice. But if you are using an older iOS version, very likely you need to make roughly 2GB’s free space for the installation.
Now, go to Settings > General > [Device] Storage, and check the remaining storage in your iPhone. If it's is less than the required amount, then try deleting some unused apps and files and see if the problem is solved.
Already having enough storage, but the iPhone still gets stuck? Then you can tell that your iOS update issue is caused by something else. Proceed to step 2.
Step 2. Reconnect your WIFI
Any iOS update would require a stable network. Or else, it can be interrupted anytime. Now, restart your Wi-Fi router. Make sure that all settings are configured with the correct credentials on your iPhone. You can even reset the network and reconnect afresh.
Next, go to an area nearby with better connectivities, be it your balcony, living room, or courtyard, etc. Then, hard reset your iPhone and start it afresh.
Step 3: Perform a Hard Reset
Chances are some minor iOS glitches are disturbing your iOS update progress. A hard reset helps by shutting down all running faulty programs and killing potential bugs in your iPhone. Most system related iOS issues can be fixed easily with a hard reset.
Here’s how to go about it:
From iPhone 8 to iPhone 13:
- Press and quickly release the volume Up button.
- Press and quickly release the volume Down button.
- Next, hold the Side button until the Apple logo shows up.
For iPhone 7 series:
- Press both buttons for Sleep/Wake and Volume down until you see the Apple logo
- When the Apple logo is displayed, release both buttons.
