idevicerestore

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

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 firmare files.

Some key features are:

  • Restore: Update firmware on iOS devices
  • Firmware: Use official IPSW firmware archive file or a directory as source
  • Update: Allows updating the device by default or erasing all data
  • Download: On demand download of latest available firmware for a device
  • Cache: Downloaded firmware files are cached locally
  • Custom Firmware: Restore custom firmware files (requires bootrom exploit)
  • Baseband: Allows you to skip NOR/Baseband upgrade
  • SHSH: Fetch TSS records and save them as ".shsh" files
  • DFU: Put devices in pwned DFU mode (limera1n devices only)
  • AP Ticket: Use custom AP ticket from a file
  • Cross-Platform: Tested on Linux, macOS, Windows and Android platforms
  • History: Developed since 2010

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.

Installation / Getting started

Debian / Ubuntu Linux

First install all required dependencies and build tools:

sudo apt-get install \
	build-essential \
	checkinstall \
	git \
	autoconf \
	automake \
	libtool-bin \
	libreadline-dev \
	libusb-1.0-0-dev \
	libplist-dev \
	libimobiledevice-dev \
	libcurl4-openssl-dev \
	libssl-dev \
	libzip-dev \
	zlib1g-dev

Then clone, build and install libirecovery which is not yet packaged:

git clone https://github.com/libimobiledevice/libirecovery.git
cd libirecovery
./autogen.sh
make
sudo make install
cd ..

If the configure processes indicates old or missing libraries, your distribution might not have yet packaged the latest versions. In that case you will have to clone these libraries separately and repeat the process in order to proceed.

Continue with cloning the actual project repository:

git clone https://github.com/libimobiledevice/idevicerestore.git
cd idevicerestore

Now you can build and install it:

./autogen.sh
make
sudo make install

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
