SuccessionRestore

Modern alternative to Cydia Eraser, a tool that allows users to restore their jailbroken device(s) back to stock iOS without a firmware update or the use of SHSH2 blobs.

Unlike Cydia Eraser, Succession uses rootfilesystem DMGs that can be dumped to perform a restore, making Succession more reliable and easier to update, while always maintaining support for modern iOS devices/firmwares.

Special thanks to comex for generously providing attach, a component that allows DMGs to be attached for use on older devices.

How it works

Succession is both an IPSW downloader/extractor and DMG mounter, allowing the ability to perform a restore on your device by:

Downloading an IPSW from Apple's servers for your device/iOS version
Extracting the largest DMG file from the downloaded IPSW
Mounting the extracted DMG file on your filesystem (at /var/mnt/succ)
Using rsync to replace any modified file with a clean versions from the mounted DMG file while deleting additional files

Once this occurs, mobile_obliterator (aka "Erase all Content and Settings") is called to complete the restore. This is NOT dangerous, as files have been correctly replaced with cleaner versions and your device is unjailbroken at this point.

Device Support

All devices running iOS 10.0 or newer are fully supported
Devices running iOS 8.0-9.3.5 are supported (exclduing the iPad Pro 12.9", iPad Pro 9.7", and iPhone 6s+) through the usage of decryption keys provided by theiphonewiki. Succession will be able to support the currently excluded devices as soon as decryption keys are posted there, and this will not require an update to Succesion to include support.

Installation

If you'd like to go back to stock iOS, you can obtain Succession from:

My Cydia Repository
Dynastic (default repository on all jailbreaks and package managers, iOS 11 or higher)
BigBoss (default respository for Cydia only)

You can also find pre-compiled versions of Succession via Github Releases if you pefer to install packages manually.

Compiling

I really don't anticipate anyone ever attempting to compile this project... but here it goes ¯\_(ツ)_/¯

In order to compile Succession, you'll need a fairly recent version of macOS with fakeroot, ldid, and dpkg installed. If you do not have these dependencies, you can easily installed them by using Homebrew:

$ brew install fakeroot
$ brew install ldid
$ brew install dpkg

As of Succession 1.4.12, you will need a fairly recent version of theos set up, you can follow their install tutorial here

Once you have these dependencies, clone Succession using Git:

$ git clone https://github.com/Samgisaninja/SuccessionRestore.git

Compiling is fairly simple afterwards, thanks to the compile and install scripts provided in the root directory of the project. You can use them to compile and install Succession directly onto your device.

Note: The install script will only work if you have OpenSSH installed on your iOS device.
