Can I downgrade iOS 18 to 17 without a computer?

 

"Hi, everyone. I'd like to downgrade from iOS 18 to iOS 17. iOS 18 is a disaster on my device, and I don't want to wait for an update. However, my computer has recently been absent from my presence. So, I'm wondering if and how I can downgrade from iOS 18 to 17 without a computer. Thank you ahead of time.”

Many people may tend to downgrade to 17 as they encounter issues like Battery Drain after updating to iOS 18. However, I’m sorry to say that downgrading iOS 18 to 16 without a computer is unavailable and it seems hard to realize at this stage to downgrade iOS 18 to 17 without a computer. Whatever software you use to reach the downgrade from iOS 18 without a PC will fail. If you hear some words that you can do without a computer, then she or he is not honest with you.
