How to Restore iPadOS 9.1 IPSW
🖥
iTunes (Windows / macOS Mojave and older) & Finder (macOS Catalina+)
- Download the iPad5,4_9.1_13B143_Restore.ipsw file to your computer.
- Connect your iPad Air 2 (Cellular) to your computer with a USB cable.
- Open Finder (macOS Catalina+) or iTunes (Windows / older macOS) and select your device.
- To Update (keeps data): hold Option (Mac) or Shift (Windows) and click Check for Update.

- Navigate to and select the downloaded .ipsw file, then confirm.

futurerestore allows restoring to unsigned firmware like this one when you have saved APTickets (blobs) from a tool like TSSSaver or shsh.host.
- Download futurerestore from github.com/futurerestore/futurerestore.
- Ensure you have a saved .shsh2 blob for iPadOS 9.1 (13B143) on your iPad Air 2 (Cellular).
- Put your device into DFU mode and run:
futurerestore -t your_blob.shsh2 --latest-sep --latest-baseband iPad5,4_9.1_13B143_Restore.ipsw
⛔ Warning: Using --latest-sep requires the latest SEP to be compatible with iPadOS 9.1. Always verify compatibility before restoring to avoid a bricked device.
📲
Entering DFU Mode
DFU (Device Firmware Update) mode is required for most manual restores. The button combination varies by device:
iPhone 8 / X and later / iPad with Face ID
Press & release Volume Up → press & release Volume Down → hold Side button until screen goes black → hold Side + Volume Down for 5 s → release Side but keep Volume Down for 10 s.
iPhone 7 / 7 Plus
Hold Side + Volume Down for 8 s → release Side but keep Volume Down for 10 s.
iPhone 6s and earlier / iPad with Home button
Hold Home + Sleep/Wake for 8 s → release Sleep/Wake but keep Home for 10 s.
💡 Tip: In DFU mode the screen stays completely black. If you see the Apple logo or a "Connect to iTunes" screen, you entered Recovery mode instead — try again.
