Before you download

  • Make sure your device’s model number is one of: iPhone16,1, D83AP. You will find it in Settings → About phone, or on the box.
  • This file is for the Global region. Installing another region’s firmware can remove features or block updates.
  • Apple devices can only restore versions marked “Signed”.
  • Back up your photos, contacts and files first, and charge the battery above 50%.

How to install

Use Finder on a Mac or the Apple Devices app / iTunes on Windows to install an IPSW file. Apple only accepts versions it is still signing, so check the “Signed” label before you download.
