I've been trying to downgrade to 18.3 RC from 18.4.1 and so far it keeps giving me this error: "The iPhone “iPhone” could not be updated. An unknown error occurred (68). 0697.0044"
Am I doing something wrong?
Help would be appreciated
Also, the ipsw came from this: https://appledb.dev/firmware/iOS/22D60.html
Thanks

18.4.1 to 18.3 is not an upgrade

#

its a downgrade

#

you have to restore (which will erase all data)

#

you can also try this

#

with a backup

#

and it might work

How to restore an iTunes backup to a lower iOS version

The same steps apply to Finder if you're using macOS Catalina or newer which doesn't have iTunes.

  1. Close iTunes
  2. Open your iTunes backup folder
  • Windows: %APPDATA%\Apple Computer\MobileSync\Backup
  • macOS: ~/Library/Application Support/MobileSync/Backup
  1. Open the folder that matches your device's UDID (you can find it in iTunes by clicking the serial number)
  2. Open Info.plist with a text editor
  • Windows: Notepad++, Sublime Text, Atom, etc. (NOT Notepad or WordPad)
  • macOS: TextEdit or others
  1. Press Ctrl+F (Windows) or Command+F (macOS) and search for the version you took your backup on (near the end of the file)
  2. Change it to the version you have downgraded to (for example, change 14.4 to 14.3)
  3. Save the file
  4. Open iTunes and try to restore the backup

If you find that iCloud is broken after restoring the backup

  1. Go to Settings -> [Your Name] -> iCloud -> Manage Storage -> Backups -> [Device Name]
  2. Tap "Delete Backup"
  3. Go back to the iCloud page, and then "iCloud Backup"
  4. Turn on "iCloud Backup" and tap "Back Up Now"
  5. Once the backup is complete, go to Settings -> General -> Reset -> Erase All Content and Settings
    (Make sure you are NOT jailbroken when you do this. Restore rootfs first if necessary.)
  6. Set your phone up again and restore the newly created iCloud backup
