How Can I Downgrade iOS 18 to iOS 17 on a Windows PC?

If you don't put your device into DFU (Device Firmware Update) mode correctly, nothing’s gonna work. When you’re downgrading  iOS 18 to iOS 17, you’ll need to enter this mode to bypass any problems. Follow the specific button sequence for your iPhone model. A Google search should give you the steps, but kind of like a dance move, practice makes perfect!

Sometimes, Windows might throw a fit while communicating with iTunes. Ensure no other processes are hammering your CPU and that you're not doing heavy downloads or games during this process. You’ll want a smooth ride with nothing else clogging things up.

A stable internet connection is vital during the process. If iTunes warns you to download something mid-downgrade and you lose your connection, you're in trouble. Use a wired connection if possible—less chance for problems!
