idevicerestore

A command-line application to restore firmware files to iOS devices.

Table of Contents

Features

The idevicerestore application is a full reimplementation of all granular steps which are performed during the restore of a firmware to a device.

In general, upgrades and downgrades are possible, however subject to availability of SHSH blobs from Apple for signing the firmware files.

Some key features are:

WARNING: This tool can easily destroy your user data irreversibly.

Use with caution and make sure to backup your data before trying to restore.

In any case, usage is at your own risk.

Building

Prerequisites

You need to have a working compiler (gcc/clang) and development environent available. This project uses autotools for the build process, allowing to have common build steps across different platforms. Only the prerequisites differ and they are described in this section.

Linux (Debian/Ubuntu based)

macOS

Windows

Configuring the source tree

You can build the source code from a git checkout, or from a .tar.bz2 release tarball from Releases. Before we can build it, the source tree has to be configured for building. The steps depend on where you got the source from.

Both ./configure and ./autogen.sh (which generates and calls configure) accept a few options, for example --prefix to allow building for a different target folder. You can simply pass them like this:

./autogen.sh --prefix=/usr/local

or

./configure --prefix=/usr/local

Once the command is successful, the last few lines of output will look like this:

[...]
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing depfiles commands
config.status: executing libtool commands

Configuration for idevicerestore 1.1.0:
-------------------------------------------

  Install prefix: .........: /usr/local

  Now type 'make' to build idevicerestore 1.1.0,
  and then 'make install' for installation.

Important

idevicerestore requires a properly installed usbmuxd for the restore procedure. Please make sure that it is either running or configured to be started automatically as soon as a device is detected in normal and/or restore mode. If properly installed this will be handled by udev/systemd.

Usage

The primary scenario is to restore a new firmware to a device. First of all attach your device to your machine.

Then simply run:

idevicerestore --latest

This will print a selection of firmware versions that are currently being signed and can be restored to the attached device. It will then attempt to download and restore the selected firmware.

By default, an update restore is performed which will preserve user data.

Mind that if the firmware file does not contain a 'Customer Upgrade Install' variant, an erase restore will be performed.

You can force restoring with erasing all data and basically resetting the device by using:

idevicerestore --erase --latest

Please consult the usage information or manual page for a full documentation of available command line options:

idevicerestore --help
man idevicerestore
