Unable to install iOS 26.7.1 on iPhone 16 Pro

Unable to download and install iOS 26.7.1 – Update fails

Hello!


I have been trying to download and install iOS 26.7.1 for two days, but I keep getting an error message saying that the update failed.


I have enough free storage space on my iPhone, and my battery is sufficiently charged. I have also tried downloading the update several times, but nothing works. Every time, the same error message appears, and the update cannot be installed.


I have attached a screenshot of the error message.


Has anyone experienced the same issue? Does anyone know how I can fix it?


Thank you in advance for your help!


Device: iPhone 16 Pro


Software: iOS 26.7.1 (attempting to install)

The first things I would do is charge the battery, leave it connected to the charge circuit, and turn of low power mode. After those steps, attempt the update again.
