# idevicerestore
-## About
+*The idevicerestore application allows to restore firmware files to iOS devices.*
-The idevicerestore tool allows to restore firmware files to iOS devices.
+## Features
-It is a full reimplementation of all granular steps which are performed during
-restore of a firmware to a device.
+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.
-To restore a device, simply run:
-```bash
-idevicerestore -l
-```
+- **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
-This will print a selection of firmware versions that are currently being signed
-for the attached device. It will then download and restore the selected firmware.
+**WARNING:** This tool can easily __destroy your user data__ irreversibly.
-By default, an update restore is performed, which will preserve the user data
-(unless the firmware image does not contain a 'Customer Upgrade Install' variant,
-in which case an erase restore will be performed).
+Use with caution and make sure to backup your data before trying to restore.

+## Installation / Getting started
+
+### Debian / Ubuntu Linux
+
+First install all required dependencies and build tools:
+```shell
+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
+```
-**In any case, usage is at your own risk.**
+Then clone, build and install [libirecovery](https://github.com/libimobiledevice/libirecovery.git) which is not yet packaged:
+```shell
+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](https://github.com/libimobiledevice/) separately and repeat the process in order to proceed.
-## Requirements
-
-Development Packages of:
-* libimobiledevice
-* libirecovery
-* libusbmuxd
-* libplist
-* libcurl
-* libzip
-* openssl
-
-Software:
-* usbmuxd
-* make
-* autoheader
-* automake
-* autoconf
-* libtool
-* pkg-config
-* gcc or clang
-
-## Installation
-
-To compile run:
-```bash
+Continue with cloning the actual project repository:
+```shell
+git clone https://github.com/libimobiledevice/idevicerestore.git
+cd idevicerestore
+```
+
+Now you can build and install it:
+```shell
./autogen.sh
make
sudo make install
```
-## Who/What/Where?
+## 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:
+```shell
+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:
+```shell
+idevicerestore --erase --latest
+```
+
+Please consult the usage information or manual page for a full documentation of
+available command line options:
+```shell
+idevicerestore --help
+man idevicerestore
+```
