WARNING: To be clear, the instructions below could result in bricking your device. Wait for the jailbreak to open and check. Find the checkra1ngui file and double-click it.
![]() ![]() ![]() Jailbreak Dmg Full File SystemWithout the passcode, you can still extract data, but the data you get will be not include any of the encrypted data (ie. An iOS device identified in a BFU state means that the device passcode has not yet been entered by the device user. For the purposes of this article, we will not be discussing BFU (Before First Unlock) jailbreaking or BFU extractions. There is NO BRUTE FORCE SUPPORT. To obtain a Full File System (FFS) extraction, you must know the passcode. Do these in the order they appear, as some of the tools are dependent on others. There are also devices (such as the iPhone XR or XS) that will run iOS12 but are not vulnerable to Checkm8.This leaves a sweet spot (in Purple in the table below) of around 7 generations of device that are vulnerable to the exploit (in Red in the table below) and are capable of running a supported version of iOS (in Blue in the table below).In preparation for extracting a phone, there are a few pieces of software you need to install on your computer. However, the jailbreak 'checkra1n' only works on devices running iOS 12.3 and above.This means that there are some devices that are vulnerable to Checkm8 (such as the iPhone 4S and 5) but not checkra1n, because they cannot run iOS12 or above. Our testing has shown that the resulting TAR file is usable by ArtEx in exactly the same way that GK Extractions are.The method we are going to focus on however is the method by fellow forensicator Mattia Epifani available at: This is a free and awesome tool that is pretty straightforward to use to obtain an FFS of a checkra1ned iOS device.Apple computer (Some of these steps will also work on Linux but this is outside of the scope of this article).Target iOS device must be vulnerable to Checkm8 and CheckRa1n.To add more clarity here, the exploit 'Checkm8' runs on any iOS device from an iPhone 4S up to and including an iPhone X. The older releases of checkra1n based on a quick perusal, shows they are all beta previews. In this article only the GUI Mac version will be shown.At the time of writing, the latest version was noted as 0.10.1 beta. The CLI also denotes the Terminal application on the Mac. It is currently only supported on Mac and Linux in both GUI (Graphical User Interface) and CLI (Command Line Interface). Photoshop express for mac freeHence the reason for installing these tools now, so that you are ready to perform the extraction after the device is jailbroken with checkra1n. After the device is checkra1ned, this script has the ability to perform either a BFU extraction, which obtains a limited amount of data if the device is locked, or a complete full file system (FFS) extraction if the device is unlocked. The iOS BFU triage script is named by the author. In this case it was renamed to checkra1n_0.10.1.app in order to distinguish it from other versions of checkra1n.Xcode CLT, brew, SSHPASS, libimobiledevice, and dialogWhy are we going on these side quests and installing more software tools? Because they are required for properly running the iOS BFU triage script. This screenshot is showing the contents of the mounted checkra1n beta 0.10.1 DMG file on the desktop.The Application folder now shows the checkra1n app installed. This screenshot shows the checkra1n beta 0.10.1 DMG file mounted on the desktop.Drag this file over top the shortcut icon of the Applications folder. If any errors occur, try typing the command instead of copy/paste to see if the issue is resolved.If this is the first time installing CLT for Xcode, and if you are on Mac OS Catalina, then the following reference is a good guide with screenshots:If you have previously installed Xcode, then you will see a different response from the Terminal. I typically install both, but the Command Line Tools should install without the need for Xcode.The Command Line Tools (CLT) includes a module called GNU Compiler Collection (GCC) which includes libraries for various languages and is necessary for this extraction process to work.To Install Command Line Tools, start the MacOS Terminal and type:Once installation has finished, you can type the following to ensure installation worked.Which should return: /Applications/Xcode.app/Contents/DeveloperYou can also confirm that GCC is installed by typing:Terminal Tips: *Sometimes, copying and pasting from website into terminal can include characters that cause issues. However, for this process, you will need the Command Line Tools which do not get installed with the App Store version of Xcode. Typically, the IDE is a graphical interface and is available from the Mac OS App Store. Ufed reader download for macUse that time to go make yourself a brew. It makes it easy to install software from outside of the Apple ecosystem.More information about HomeBrew can be found at To install, enter the MacOS Terminal and type (or copy and paste) the following command and then press ENTER:The terminal should respond by identifying what will be installed, and where brew will be installed to.This process can take a good few minutes. The reply shows that CLT for Xcode is already installed.HomeBrew is a free package management tool for MacOS. As a workaround, we typed the command: xcode-select -install. This is very helpful for scripting." Again, we will use HomeBrew to install from the MacOS Terminal using the following command:Dialog is little tool to make MacOS show user friendly dialog boxes from shell scripts. To install libimobiledevice, type the command shown below in terminal and press ENTER.The terminal should respond with messages stating it is installing dependencies.According to that page, SSHPASS is "a tiny utility, which allows you to provide the ssh password without using the prompt.
