I need some clarification on something, so the checkm8/checkrain exploits allows you to downgrade/upgrade to any supported version, correct?
so, it will boot normally on any version that you downgrade / upgrade to but you'd need your pc to turn it on with jailbreak.
ok.. so why can't i just use any jailbreak tool supported for that version

In today's video, we're discussing the latest CheckRa1n Jailbreak news. Cydia and Zebra Package Manager for iOS have both been achieved on CheckRa1n Jailbreak for iOS 13.1.3, iOS 13.0, iOS 12.4.1 and so on, on iPhone X all the way down to iPhone 5S using the CheckM8 BootROM exploit. 

#CheckRa1n Team has posted just a few hours ago a photo of three devices running the CheckRa1n jailbreak with both #Cydia and #Zebra installed, thus confirming that CheckRa1n comes with an application that allows you to choose which package manager you will be using. For now, it's unsure how many package managers will be available. Cydia and Zebra are open source. So is Installer 5 and Saily, but Sileo is kept closed source by Coolstar / Electra / Chimera Team, so it may not be included. 

The CheckRa1n #Jailbreak cannot be patched, so support for all upcoming iOS versions such as #iOS 13.2, iOS 13.2.x and so on is very easy to add. However, the CheckM8 exploit does not support the A12 devices and neither does it support the A13 devices, so no iPhone 11 and no iPhone XS, XR and XS Max either.

I know it sounds like Conspiracy theory but could it be possible that Apple paid money to the checkra1n team so they don’t publish the jailbreak?

As my thread. I wonder if I can jailbreak my device iphone Xs ios 12.1 by Uncover. I’m on chimera now but when I update packages from sileo my device turn into black screen and shutdown 2 times in several hours

In today's video, we're discussing the current status of the iOS 13.0, #iOS 13.1.2, iOS 13.1.3 and also iOS 12.4.1 #Jailbreak, for all the devices including A12 devices and A13 devices. As you probably know, A12 devices are the iPhone XS, iPhone XS Max, and iPhone XR, and A13 devices are the iPhone 11 variants released this year. In the video we're discussing the current iOS kernel exploits available, which ones work on which types of devices and what are the best iOS versions to stay on if you wanna jailbreak your device as soon as possible.

We're also discussing about CheckM8 and its compatible devices, as well as what should people who don't have a device compatible with #CheckM8 / CheckRa1n should do. For those devices, such as the #A12 and A13 ones, #tfp0 kernel exploits are still vital for a successful jailbreak and people should still choose the versions they update to wisely.

For the devices compatible with CheckM8, which are the iPhone X all the way down to iPhone 4S, the iOS version they stay on is completely irrelevant because the exploit is not patchable and thus we can use it to jailbreak iOS 13, iOS 12 and any other iOS version, past present or future. 

Hey,
I want to know if is possible to downgrade IOS 13.1.3 to 12.4/12.4.1 to 12.4

Hello guys when I try to use checkm8 exploit, terminal says that device is not supported , I tried latest iOS of iPhone 6 , and iOS  13.1.3 on iPhone SE , any ideas?

Hello everyone,

I'm trying to compile the last build of tsschecker released by s0uthwes and tihmstar

I get the following error when trying to compile it.

the configure part is ok:
 

In this video, we're going to start the process of CFW creation for iOS 13.1.3, #iOS 13.0, iOS 12.4.1 or even iOS 11 (any iOS version that works with CheckM8 compatible devices). And as we start, the first logical step is to be able to extract the decryption keys for iBEC, iBSS, and iBoot which need patching for a CFW to work. These files are packed inside an IM4P container which also contains the decryption key and IV, but these keys are encrypted themselves in a KBAG which can only be decrypted by the device's chip. While we cannot get access to the GID key, we can use CheckM8 exploit by @axi0mX to decrypt these.

This step is crucial in the process of CFW creation on iOS because if you cannot decrypt the files, you cannot patch them. The CheckM8 exploit released by @axi0mX is compatible with iPhone 4S all the way up to iPhone X on all iOS versions compatible with these devices, past present or future. So you can do this procedure on any supported iOS version. Keep in mind that the keys you obtain using #CheckM8 are usable for your iPhone model. For example, if you have an iPhone X and you extract the keys for iOS 13.1.3 iBoot, the keys will work on all iPhone X devices on that version. The GID key changes per CPU not per individual device.

Hi, I'd love to see a video like good old times on how to bypass an iCloud lock on iPhone 7 (4s-X) as CheckM8 is out!
