I had the same problem -- tried to install iOS 15.7 on iPhone 8 and got the "software update failed" error.


Here's what worked: I freed up enough storage space until I had about 9 GB free. That's it.


I originally tried when I had about 4-5 GB free. It didn't install, and I got the exact same error as above.


I tried again when I had about 7 GB free. It still didn't install; same error.


Once I freed up enough storage space (by deleting apps and things) until I had about 9 GB free, then the update installed, no problem.

To the people claiming you need approx 10+ GBs of free storage on your phone for the new iOS to successfully install...what about those of us who literally can't free up that much memory? My phone's only 25GB, I already transferred nearly all my photos and managed to successfully download the new iOS, which took up 5GB. I have 6.3GB of extra memory right now and literally nowhere to get more memory space from. I've been trying to install it for three hours now to no avail. I need to update my iPhone SE due to WhatsApp policies as they will stop supporting my current version of iOS. Am I seriously supposed to buy a new iPhone solely due to the fact that the update requires an ungodly amount of free memory storage, which isn't even listed anywhere?
