How to Go Back to a Previous Version of iOS on Your iPhone

Going back to a previous iOS version on your iPhone involves downloading the appropriate firmware file, using iTunes or Finder on your computer to restore your device, and preventing the device from auto-updating. Once complete, your iPhone will function on the older iOS version, but note that this may void your warranty or violate Apple’s terms of service.

After completing the process, you might not be able to access certain features or security updates that come with the newer iOS versions. Additionally, some apps might not function correctly if they require the latest iOS version.
