As we all know by now the jailbreak community being upside down since 27th of September 2019. It marked some interesting achievement in whole jailbreak history. Now we have an unpatchable exploit to jailbreak out Apple devices forever. Apple might feel like a slap in the face. So without furthermore, I'll tell the reason why we become so much excited. It's because of Checkm8.
Checkm8 is the latest exploit which was discovered by the security researcher @axi0mX. And it sounds like "Checkmate" and they definitely did it on purpose, don't you think? So there is a number of specialties in this exploit. Number one is checkm8 could not be patched up with software updates, like ever. The reason is checkm8 is a bootrom exploit which is more effective on hardware than software.
And not only that we could be jailbreak almost any kind of iPhones, but the iPad and iPod also touch including new generations. As it says it will be iPhone 4 to iPhone X. All the A5 to A12 chipsets. It will be amazing to have one rooting tool for any jailbroken device right?
Furthermore, you will no longer have to be bound to the non-jailbreakable iOS versions even if Apple insists you to do so. Because checkm8 exploit is capable of downgrading your iOS version without essential Apple sign-ins.
So who is the genius behind all of this? It is not other than the famous hacker and security researcher @axi0mX. He was able to discover checkm8 exploit and he released it to the jailbreak community completely free for testing and developing upon it. He was able to jailbreak iPhone X already.
And he posted about it on the twitter also. But not alone, with the support of the Yalu jailbreak creator Luca Todesco. The posted video about iPhone X starting in Verbose mode running iOS 13.1.1. But furthermore, he mentioned it just got 2 seconds to jailbreak it after starting DFU mode in the iPhone.
But don't forget that Checkm8 is an exploit. Not a jailbreak tool. So we could not jailbreak our iPhone, iPad and iPod touch with it just using checkm8. It has to be utilized in a tethered or semi-tethered jailbreak tool which is USB-based. Otherwise, we couldn't jailbreak it right away. But as we can see, it is already caught some attention from the higher places in the jailbreak society.
It's the first time since 2010 that we could hear about this kind of valuable exploit. Until now all the jailbreak exploits that we used to jailbreak is for our devices are software-based. So Apple is always ahead of us with fixing the patches in the system. But not anymore.
Most apple device users do not have an idea about bootrom exploit. Bootrom exploit is rare and valuable because it will exploit the device hardware instead of software. So apple will not be able to release any software update to patch it and fix it. Which means that these devices are jailbreakable for a lifetime. The only solution available for apple is to recall all the devices and fix this exploit at the hardware-level. Bootrom exploit came to the public after a long time.
You might see the tweets of @axi0mX about Verbose mode running iOS 13.1.1. Because he was able to perform a jailbreak on iOS 13.1.1 which runs on an iPhone X with the help of the Luca Todesco, the developer of the Yalu Jailbreak. Furthermore, he also stated that it only took 2 seconds to jailbreak the iPhone using checkm8 after starting it in DFU mode. And as one of his tweet, he mentioned that most generations of iPhones and iPads are vulnerable including iPhone 4 to iPhone X. which means the A5 chip to A11 chip. This already made a chaotic atmosphere in the jailbreak community. Because we do not have any public BootRom exploit since 2010, from iPhone 4.
Maybe. Because as we can see almost all the main characters are in the play already. Specially Pwn20wnd and CoolStar already started to show interest. But some actions of the Coolstar have offended the jailbreak community in some way in my opinion. The reason is the way he talked in the recent tweet that he stated he is officially ending all work on A12+ on a firmware higher than 12.1.2.
And in his announcement, he was cleary jab at Unc0ver jailbreak tool which recently released their first public beta released for A12 devices run upto iOS 12.4. In his words it a “buggy jailbreaks on A12”. But most likely we will be heard about the jailbreak tool soon as my opinion even though they have small quarrels among them.
Anyhow, Coolstar and Pwn20wnd have started a cold war between them. If the Coolstar won it you will see a jailbreak tool which is definitely installed, Sileo. And if it is Pwn20wnd there will be a upgradation for the Unc0ver and you will continue using Cydia App Store. But already this can be considered a huge victory and thanks go to @axi0mX who have discovered checkm8 and release it to jailbreak community for free. So things are going to be interesting again. Don't you think so?
As I mentioned earlier the developers have already started their work on checkm8 BootRom exploit. The main competitors are the Pwn20wnd the creator of the unc0ver and the Coolstar who is the leader in Electra team. If we checked their social media we could see they are stating that they are going to focus on this now. Coolstar clearly mentioned that and he quit in A12+ on a firmware higher than iOS 12.1.2. And Pwn20wnd also appeared to be an idea with checkm8. So we will have a universal iOS jailbreak tool in the near future.
