What is Checkra1n jailbreak?
Checkra1n iOS 13.1.2 jailbreak based on recently released checkm8 bootrom exploit has essentially been announced.
Luca Todesco and now axi0mX has taken to Twitter to share a screenshot of an Apple iPhone being exploited by a custom-built jailbreak that he is calling checkra1n (like Geohot’s limera1n).
And yes, this jailbreak is built on top of the checkm8 exploit, which means that it will offer compatibility for all A5-A11 devices regardless of the firmware that they are running.
Is checkm8 a Jailbreak?
Checkm8 is an exploit and not a jailbreak. It is, in fact, possible to leverage Checkm8 to load custom or modified kernels and support additional jailbreak capabilities or sideloaded apps, but so far this has not been publicly achieved.
Since the exploit itself doesn’t persist across device reboots, persistence and other critical modifications would require additional vulnerabilities in iOS or its kernel.
All the iOS versions (which is run on above-supported devices including latest iOS 13.2, iOS 13.1.2, iOS 13.1.1, iOS 13.1, iOS 13)
Compatible devices – Checkm8 jailbreak

- iPhone 5, 5C & 5S,

- iPhone 7 / 7 Plus,
- iPhone 8 / 8 Plus and iPhone X,
- As well as all iPods from iPod Touch 5 to iPod Touch 7th Generation, and all iPads that are not A12.
Benefits and constraints
That the jailbreak uses a new exploit named Checkm8 that exploits vulnerabilities in Apple’s Bootrom (secure boot ROM) to grant phone owners full control over their device.
Unlike just about every jailbreak exploit released in the past nine years, it targets the iOS bootrom, which contains the very first code that’s executed when an iDevice is turned on.
Because the bootrom is contained in read-only memory inside a chip, jailbreak vulnerabilities that reside there can’t be patched.
That benefit is countered by the threat that the same jailbreak will give hackers a new way to install malware or unlock iPhones that are lost, stolen, or confiscated by unscrupulous authorities.
Checkm8 Jailbreak Features
Features the Checkm8 exploit allows include as mentioned below:
- Jailbreak and downgrade iPhone 3GS (new bootrom) with alloc8 untethered bootrom exploit.
- Pwned DFU Mode with steaks4uce exploits for S5L8720 devices.
- Pwned DFU Mode with limera1n exploits for S5L8920/S5L8922 devices.
- Pwned DFU Mode with SHAtter exploits for S5L8930 devices.
- Dump SecureROM on S5L8920/S5L8922/S5L8930 devices.
- Dump NOR on S5L8920 devices.
- Flash NOR on S5L8920 devices.
- Encrypt or decrypt hex data on a connected device in pwned DFU Mode using its GID or UID key.
How to install Checkm8 Jailbreak
Install checkm8 jailbreak exploit with the computer ( Just works only Mac or on Linux. No Windows tool for now. )
- Download iPwnDFU from here: https://github.com/axi0mX/ipwndfu
- Unpack the ZIP file on your Desktop.
- Open Terminal and run “cd /PathToYourExtractedFile” (change PathToYourExtractedFile to the actual path).
- Connect your iDevice to the computer using a USB cable.
- Put the device in DFU Mode. Before iPhone 7, you do it by pressing and holding Power + Home until the screen is off, wait a few seconds, release the POWER button but keep pressing the HOME button for another 10 seconds. the screen should remain black. For iPhone 7 and newer, you need to press and hold POWER + VOLUME DOWN until the screen is off, wait a few seconds, release the POWER button and keep pressing the VOLUME DOWN button for another
- In the Terminal run “./ipwndfu -p”. If you get an error, run it again until you get a message telling you the iDevice is now in Pwned DFU mode.
- The Pwned DFU mode will remain until the phone reboots. You should not see anything on the screen (black screen). This basically it. You can now DUMP the ScureROM, demote the device to enable JTAG, and soon you’ll be able to restore CFWs, do downgrades, etc.
CODE AVAILABLE ON GITHUB
Axi0mX’s jailbreak is available on GitHub. The code is marked as a “beta” release.
Most jailbreaking exploits are usually packaged in easy to use tools. For the moment, Checkm8 is in a very raw form and it isn’t recommended for users without proper technical skills as it could easily result in bricked devices.Axi0mX also published a Jailbreak guide, Others features will be added soon, he said.
“A bootrom exploit for older devices makes iOS better for everyone.
Jailbreakers and tweak developers will be able to jailbreak their phones on the latest version, and they will not need to stay on older iOS versions waiting for a jailbreak. They will be safer.
”Axi0mX said this vulnerability cannot be exploited remotely, the attackers need to have physical access to the device.
