Restore Downgrade

Restore/Downgrade option in Legacy iOS Kit is one of the options in the Main Menu. Restoring refers to the process of flashing firmware to the device, and may be for downgrading or upgrading to another iOS version. The options available in the Restore/Downgrade section can vary depending on the device.

Selection

• OTA Downgrade
• powdersn0w
• Latest iOS version
• Other iOS versions, depending on the device
  • For the iPhone 3GS and iPod touch 2, many iOS versions are available in the menu
• Other (use SHSH blobs)
  • This option is useful for iOS devices with SHSH blobs for unsigned iOS versions and would like to use them to restore.
  • This is supported on all supported devices that use SHSH blobs (from the 3GS all the way to the iPhone 7.)
• Other (Custom IPSW)
  • This option should only be used for restoring to IPSWs NOT made by Legacy iOS Kit. Examples: restoring a GeekGrade or whited00r IPSW
  • For iPhone 2G, 3G, iPod touch 1, this option can be used for restoring to any iOS version.
• Other (Tethered)
  • This option is for tethered downgrades, meaning the device requires a computer in order to boot.
  • To boot up a tethered downgrade, go to: Other Utilities -> Just Boot
• DFU IPSW
  • If your button/s are broken, you can use a DFU IPSW to force the device to DFU mode. This will also clear all device data, so backup data and SHSH blobs before proceeding.

Options

These options are prompted for selections and iOS versions they are available for. All of these options apply to 32-bit devices only.

• Jailbreak Option is for adding a jailbreak when creating a custom IPSW. This option is enabled by default.
• Memory Option is for using system RAM when creating a custom IPSW. This option is enabled by default. This option can be disabled if the PC/Mac does not have sufficient RAM for the operation (8 GB or more is recommended.)
• Hacktivate Option is for hacktivation of iPhones. This option is useful especially when the user does not have a valid SIM card available.
• Verbose Boot Option is for enabling verbose boot for the custom IPSW. This option is available for powdersn0w IPSWs only.
