Restoring with blobs using FutureRestore

For support in English, ask for help on the r/Jailbreak Discord Server.


If you are on iOS 15, you will need to follow thisOpen in new window guide instead. Note that if you are on iOS 15 and are on an A12+ device, you will not be able to downgrade, as there is currently no jailbreak or exploits which can be used to set nonce on A12+ devices running iOS 15.


  • Blobs saved for the version you want to restore to
  • A jailbroken device


Getting Started

  1. Open your package manager on your jailbroken iDevice
  2. Add repo.1conan.comOpen in new window to your sources
  3. Download and install dimentio
  4. Download and install NewTerm2

Setting nonce


If you're using unc0ver on iOS 14.6-14.8, you cannot use dimentio as libkrw isn't functioning. You should set your generator from unc0ver's settings instead.

  1. Open your blob in a text editor and search for generatorGeneratorExample

  2. Note down the value inside the <string> field

    • This should be a 0x followed 16 characters which will be a combination of letters and numbers. This is your generator.

NOTE: If there is no generator value, try to remember which jailbreak you were using at the time of saving blobs. If you were using unc0ver, your generator is most likely 0x1111111111111111, and if you were using Chimera/Odyssey/Taurine, your generator is most likely 0xbd34a880be0b53f3

  1. Open NewTerm 2 on your iDevice and type the following command, where [generator] is the value you just grabbed: su root -c 'dimentio [generator]'

  2. When asked for a password, enter your root password

    • By default, this is set to alpine, not your phone's password.
  3. Once the command executes, a lot of text should appear

  4. Near the end of the text, you should see the line Set nonce to [generator]

On Computer

  1. Connect your iDevice to your computer

  2. Make sure that your computer is trusted by your device

    • Optionally, you can create a full backup of your device through iTunes or Finder
  3. Open FutureRestoreGUI on your computer

    • If prompted by Windows Defender or other anti-virus software, allow the program to run - it’s safe
  4. When opening FutureRestoreGUI, you should be greeted by this menu: image

  5. Click the Download FutureRestore button to fetch the latest version of FutureRestore ** Note:** If your device supports iOS 15 or is a WiFi only-iPad, you will need to click the Settings button and enable Futurerestore Beta, then click the Download FutureRestore button. This version of futurerestore requires macOS or Linux.

  6. Click the Select Blob File... button and select your blob .shsh2 file

  7. Click the Select Target iPSW File... and select your .ipsw file

  8. Then click the Next button to navigate to the Options menu, make sure Extra Logs is enabled

  9. If you are not downgrading, then it is safe to enable Preserve Data in the options menu in order to keep data. However using it while downgrading may be dangerous

  10. Do not enable AP Nonce Collision on any modern devices

  11. Click Next to navigate to the controls menu
