MANUAL SOFTWARE UPDATE:
Hello apple community. I've been struggling with this for a week. I started using an iPhone 8 that hasn't been updated for a few years now meaning its still running on version 12.1.4.
My issue is now when I try updating it to the latest version it says "iOS version does not support wirelessly updating to latest version. Please connect your device to iTunes on a computer to update to the latest software".
I've always used android so I am very new to the apple community. I do have a laptop BUT its not a Mac book and I assume I need a Mac for this. If anyone knows what to do in the situation please reach out, I really need help. Thank you in Advance.
