futurerestore is a hacked up idevicerestore wrapper, which allows manually specifying SEP and Baseband for restoring

Latest compiled version can be found here:
(MacOS & Linux)
http://api.tihmstar.net/builds/futurerestore/futurerestore-latest.zip

• Supports the following downgrade methods
  • Prometheus 64bit devices (generator and nonce collision mode)
  • Odysseus for 32bit devices
  • Re-restoring 32bit devices to iOS 9 with @alitek123's no-nonce method
• Allows restoring any nonmatching signed iOS/Sep/Baseband

• Bundled Libs

Those don't need to be installed manually

• jsmn

• External Libs

  Make sure these are installed
  • libzip
  • libcurl
  • openssl (or CommonCrypto on OSX)
  • libplist

• Submodules

  Make sure these projects compile on your system (install it's dependencies)
  • tsschecker
  • img4tool
  • idevicerestore

Usage: futurerestore [OPTIONS] IPSW

Downgrade/Upgrade/Re-restore same iOS. Whenever you read "downgrade" nowadays it means you can also upgrade and re-restore if you're on the same iOS. Basically this allows restoring an iOS and the installed iOS doesn't matter.

• Jailbreak
• SHSH2 files with a generator
• nonceEnabler patch enabled

You can downgrade if the destination iOS is compatible with the latest signed SEP and if you have shsh2 files with a generator for that iOS.

1. Device must be jailbroken and nonceEnabler patch must be active
2. Open shsh file and look up the generator

• Looks like this: <key>generator</key><string>0xde3318d224cf14a1</string>

3. Write the generator to device's NVRAM

• SSH into the device and run nvram com.apple.System.boot-nonce=0xde3318d224cf14a1 to set the generator 0xde3318d224cf14a1
• verify with nvram -p

4. Connect your device in normal mode to computer
5. On the computer run futurerestore -t ticket.shsh --latest-baseband --latest-sep ios.ipsw

Prometheus

NonceEnabler

1. Get nvpatch https://github.com/Siguza/ios-kern-utils/releases/
2. Run on the device nvpatch com.apple.System.boot-nonce

• reboot
• reactivate jailbreak with https://jbme.qwertyoruiop.com/
• done

• Use cl0ver (https://github.com/Siguza/cl0ver)

• iPhone5s or iPad Air on iOS 9.1 - 10.2
• No Jailbreak required
• SHSH files with customly chosen APNonce
• The shsh file needs to have one of the nonces, which the device generates a lot

You can downgrade if the destination iOS is compatible with the latest signed SEP. You also need to have special shsh files. If you don't know what this is, you probably can NOT use this method!

1. Connect your device in normal mode or recovery mode
2. On the computer run futurerestore -w -t ticket.shsh --latest-baseband --latest-sep ios.ipsw

• If you have saved multiple tickets with different nonces you can specify more than one to speed up the process: futurerestore -w -t t1.shsh -t t2.shsh -t t3.shsh -t t4.shsh --latest-baseband --latest-sep ios.ipsw

• futurerestore compiled with libipatcher (odysseus support)
• Jailbreak or bootrom exploit (limera1n)
• Firmware keys for the device/destination iOS must be public (check ipsw.me)
• SHSH files for the destination iOS (OTA blobs work too!)

If you have a jailbroken 32bit device you can downgrade to any iOS you have blobs for. You can still get OTA blobs for iOS 6.1.3 and 8.4.1 for some devices and use those.

1. Get device into kDFU/pwnDFU

• Pre-iPhone4s (limera1n devices):
  • Enter pwndfu mode with redsn0w or any other tool
• iPhone4s and later:
  • Jailbreak required!
  • Enter kDFU mode with kDFU app (cydia: repo.tihmstar.net) or by loading a pwniBSS from any existing odysseus bundle.

2. Connect your device to computer in kDFU mode (or pwnDFU mode)
3. On the computer run futurerestore --use-pwndfu -t ticket.shsh --latest-baseband ios.ipsw

Futurerestore + Libipatcher

kDFU App

Enter kDFU Mode (watch up to the point where the screen goes black)

You can use any odysseus bundle for this

• No Jailbreak required
• SHSH files without a nonce (noNonce APTickets)

If you have shsh files for iOS9 which do not contain a nonce, you can restore to that firmware.

1. Connect your device in DFU mode
2. On the computer run futurerestore -t ticket.shsh --latest-baseband ios9.ipsw
