Unable to install update
Struggling to install the update on my iPhone 11, I'm consistently receiving an error message that states I'm unable to install the update due to unknown reasons.
iPhone 11, iOS 17
What iOS version are you currently running and to what are your trying to update?
...an error message that states I'm unable to install the update due to unknown reasons.
How much free space on your phone? A common cause of that message is that you do not have enough free space in your storage to allow room for the compressed installer and the resulting decompressed temp files. The 17.6 update for my iPhone SE2020 was 7.5GB before decompressing.
