In this article, we look at how to set up checkra1n for jailbreaking various Apple devices using iOS and what needs attention.
iOS of the devices or another way to pronounce it Apple ecosystem It is a known fact that it has a more closed structure compared to other operating systems and ecosystems. While this is the case with most mobile devices, it does iOS It is thought that there are even more restrictions when it comes to devices.
On the one hand, who want to use their device fully in return for the money they pay. iPhone or “IDevice” While there are users, on the other hand, there are companies that are restricted due to various security or other reasons. Jailbreak However, here is a technique that emerged as a result of this conflict.

Apple Although it is an unofficial transaction that is not supported by the US and most countries legal to apply to devices.
Jailbreak process Android on the side of “Root” the transition to the user or the common expression “Root” throwing iOS ecosystem you can think of it like the case for. Android On the side of the store, external application installation can make various customizations more easily, Apple These operations are much more limited in mobile devices. For these reasons JailBreak while providing freedom to the user in various areas, Apple It can void devices as it is not officially supported by the community and developed independently by the community.
In this article iOS on devices Jailbreak used to make the transaction “Checkra1n” We will talk about the installation of the software and the things that need attention. From companies specialized in forensic informatics Elcomsoft Let’s start to explain what you should do by using the narration.
Why is checkra1n used?
First of all, we should mention that it is up to you to jailbreak a device or not. If you have decided to dispose of a device, you usually have a few evaluation options. Perhaps the most logical and instructive of these options is removing restrictions by jailbreaking the device. However, we would like to point out again that this process will take your device out of warranty and has various risks. Therefore we are not responsible for any problems you may have. This is a guide and you are free to apply or not.
If you decide to jailbreak, you have the option to remove the restrictions using multiple methods, similar to the decision you made at the time of the initial disposal. If we count a few of them; unc0ver, Odyssey or the technical one our article will tell checkra1n may be. Checkra1n The main reason why the method or software stands out more than others is that it also supports many current versions of iOS, which are not available in most jailbreak methods.
Also in the field of forensic informatics checkra1nfrom the suspect’s locked device BFU (Before First / Unlock – Before First Unlock) The only jailbreak that allows it to be exploited using an unknown password. Apart from that, there is another important reason. Checkra1n jailbreaking IPA there is no need to sign the file.
Compatibility and CLI Mode
checkr1n jailbreakCompatible with Apple TV (Apple TV HD) and Apple TV 4K devices, from iPhone 5S to iPhone X, as well as many iPad models. Since it is constantly updated software, we recommend you to check which iOS versions it supports.
Checkra1n jailbreak not officially supported by developers iOS If you want to apply in version “Allow untested versions / Allow untested versions” You need to check the option. Elcomsoft According to the tests conducted by, checkra1n seems to work on iOS 13.5.1 and 13.6 beta 4. For versions 12.3 and below, don’t even bother trying.
In addition Elcomsoft suggested by checkra1n jailbreak way of doing CLI over GUI use of. It is said that you can do this more reliably this way. Also, the device in USB restricted mode BFU This is the only way forward if you have access to it.

If you only have a Windows computer Ra1nUSB / Bootrain or ra1nstorm With the help of the bootable, you can start by inserting the flash memory and booting.
also Raspberry Pi Although it has support, developers use the exploitin Raspberry Pi Zero and On Raspberry Pi 3 he thinks it will not work properly.
Our recommendation is both to save time and to tie the work to the “solid stake”. Mac computers your use. Not tested in Big Sur but It works great in Catalina That being said.
Cables and Connection
Definitely a good Lightning to USB (Type-A) Take care to use cables. USB-C if the point is possible do not use. You may be wondering why it should not be used. The developers themselves have an explanation for this.
“Unfortunately, Lightning to USB-C cables cannot be used to enter DFU mode and cause problems. There is nothing that can be done about it, and that includes USB-C cables from Apple and third-party cable manufacturers. If the cable does not work, we recommend you to use a USB-A cable with the help of a USB-A to C adapter, if necessary. “
Technically, they explain this issue as follows:
“BootROM will switch to DFU only if it detects USB voltage. This goes all the way to ensuring that certain pins on the Tristar chip are controlled. Since the Tristar chips do this based on the ID of the cable used, we think that USB-A and USB-C cables have different IDs. One of the USB-C cables causes the Tristar chip to fail to display the USB voltage pin. “
In addition, do not use any USB multiplexer Hub. Use only USB-C to USB-A adapter if necessary.
Other Tips for Checkra1n
