Legacy iOS Kit

Features

  • Legacy iOS Kit supports all 32-bit iOS devices, and some 64-bit (A7/A8/A9/A10/A11) devices
    • Devices that received iOS 16 and newer will only have limited functionality (e.g. sideloading) and some features like SSH ramdisk are not supported
    • Legacy iOS Kit defines legacy devices as all iOS devices that are vulnerable to checkm8 and older
  • Restore to signed OTA versions (iOS 8.4.1 and/or 6.1.3) on A5/A6 devices
  • Restore to iOS 10.3.3 (signed OTA version) on supported A7 devices
  • Restore supported devices to unsigned versions with SHSH blobs
  • Restore to unsigned iOS versions with iOS 7 blobs (powdersn0w)
  • Restore supported 32-bit devices to unsigned iOS versions "without" blobs
    • Includes downgrading iPhone 2G, 3G, 3GS, iPhone 4 GSM and CDMA, iPod touch 1, 2, 3, iPad 1
    • "without" is in quotes because powdersn0w uses iOS 5/7 blobs for touch 3 and A4 devices, but it is signed for everyone to use
    • Other devices however are true blobless
  • Tethered downgrades/restores to supported iOS versions for A5(X)/A6(X) and some other 32-bit devices
  • Jailbreak all 32-bit iOS devices on nearly any iOS version
    • Available on iOS versions 3.0 to 9.3.4 with some small exceptions
  • Hacktivation for iPhone 2G, 3G, 3GS, 4 GSM (activate without valid SIM card)
  • FourThree Utility - Dualboot iOS 4.3.x for the iPad 2
  • Boot SSH Ramdisk for supported 32-bit and 64-bit devices
  • Save Onboard SHSH blobs for supported 32-bit and 64-bit devices
  • Install IPA files for supported devices with AppSync Unified installed
  • Sideload IPA files for supported devices on Linux (and macOS)
  • Save SHSH blobs from Cydia servers for 32-bit devices
  • Enter pwned iBSS/kDFU mode for supported 32-bit devices
  • Save onboard SHSH blobs for jailbroken 64-bit devices (deverser)
    • This also saves onboard Cryptex APTicket and seed for iOS 16+ (x8A4)
  • Install TrollStore using SSH Ramdisk for supported 64-bit devices on iOS 14/15
  • Clear NVRAM for 32-bit devices
  • Device activation using ideviceactivation (especially useful for iOS 4 and lower)
  • The latest baseband will be flashed for certain A5/A6 devices (for iPhone 4S, 5, 5C, iPad 4, mini 1)
  • Dumping and stitching baseband to IPSW (requires --disable-bbupdate)
  • Dumping and stitching activation records to IPSW (requires --activation-records)
  • Data Management - Backup and restore, mount device, erase all content and settings
  • Misc Utilities - Pair device, export data and battery info, shutdown/restart device, and more
