You're correct that Apple only allows upgrading via official channels, and downgrading is not officially supported through iOS updates. However, it is possible to do so using third-party tools and firmware files, but please note that this process involves some risks, including potential data loss and the possibility of voiding warranty. Proceed carefully and make sure to back up your data before attempting.

Important Notes Before You Start:

  • Download the correct firmware: You will need the iOS 17 IPSW firmware file compatible with your iPhone 14 Pro.
  • Tools needed: Third-party software like 3uTools, RedSn0w (more complex), or other reliable tools that support iOS firmware flashing.
  • Ensure your PC has iTunes installed: You can download iTunes from Apple’s official website.

 

Here's a step-by-step guide to help you downgrade from iOS 18 to 17 on your Windows PC:
1. Download the iOS 17 Firmware (IPSW file)

   Visit reputable sources like ipsw.me and select your device model (iPhone 14 Pro).
    Download the latest iOS 17 IPSW file compatible with your device.
    Save it to a known location on your PC.

2. Download and Install 3uTools (Recommended)
    Download 3uTools from 3uTools.net.
    Install and launch the software.

3. Connect Your iPhone to PC

    Use a Lightning cable to connect your iPhone.
    Open 3uTools; it should recognize your device.

4. Enter Device into Recovery Mode
Follow the prompts in 3uTools to put your iPhone into DFU mode:
    Quickly press and release volume up.
    Quickly press and release volume down.
    Hold the side button until the screen turns black.
    Release the side button and then hold both side button and volume down for a few seconds until the device is in DFU mode.

5. Select the IPSW Firmware for Downgrade
    In 3uTools, go to the "Flash & JB" tab.
    Click "Select Firmware" and choose the iOS 17 IPSW file you downloaded.
    Make sure "Retain User Data" is unchecked unless you want to keep data (note: downgrading often requires a clean restore).

6. Start downgrading from iOS 18 to 17
    Click "Flash" to start the process.
    Wait for the process to complete; do not disconnect your device during this time.
    Your iPhone will reboot once the process is finished, and it should now be on iOS 17.
