Came here just to scroll through the video but caught. Very well done 👍 You should try to make a more “click baiyt” title to get some traction

So if this is unpatchable then why isn’t there a jailbreak for any version of IOS 15? I’m so confused.

@CeaddL 2 жыл бұрын

The checkm8 exploit is unpatchable because the vulnerable code resides on a chip that cannot be changed or “fixed”. Any iPhone pre iPhone 10 is still vulnerable to checkm8 even on iOS 15/16. The reason you don’t have a working jailbreak today is due to changes in iOS and the lack of jailbreak development. Apple worked very hard to lock down iOS with iOS 15, mostly by using signature checks on the core os. If checkm8 is used to modify iOS (jailbreak it) those checks will fail and iOS won’t boot. Checkm8 can actually overcome this but the work required to do it outweighs the benefits to the people who can do it. Basically because there is no incentive to the small group of people able to do it, they don’t. 90% of these people have lucrative careers that consume most of their time. There is no motivation to donate months of their free time to create a free tool that a small group of people will use. This has been a long time coming in the jailbreak community and myself I am not surprised. I’ve been jailbreaking 12 years. It had to end sometime. Will you see an iOS 15 jailbreak? Maybe. There is always someone out there looking to make a name for themselves, if enough people group the right talents together it’s honestly possible we could see a jailbreak again. Is jailbreaking dead? Well… even if we see one or two more jailbreaks in the coming years I personally think the community is done. I was a jailbreak tweak developer. cydia.ceadd.ca

@@CeaddL Wow, thanks for the heartfelt response. It all makes more sense now, I’ve really missed the heydays of jailbreaking thanks to being an Android user for most of my time. I got an old iPad and really wanted to use it for emulation given the 4:3 aspect ratio but it’s on 15.3 and that tethered thing where you get Delta and one other app is a bit crap. I guess I can download retroarch but I doubt it’s well supported. I really want dolphin, although I’m not sure this tablet would really be up to the task. Then there’s other IOS games I’d like to play. Regardless. I’m sorry to hear this scene you’ve been so into has died a slow and painful death. Maybe one day something will be born from the ashes but you know, IOS is getting better these days, lockscreen widgets are here and such so I guess we don’t need tweaks like we used to. I still have an iPhone 5C to mess around with though. Thanks again.

You didnt mention anything about icloud locked phones.

@CeaddL 5 жыл бұрын

Correct, and on purpose. I do not condone nor support iCloud removal or device theft. If you have a iCloud locked device and need it unlocked you can contact Apple with the original receipt and they can help you. Otherwise have a good day.

@@CeaddL That's definitely interesting what you say about possibly removing the limitation of how many times one can guess the pass code. Hopefully I'm able to access such tools.

Yeah, something I didn’t cover in the video, newer devices like iPhone 8,x,xs and 11 appear to use the SEP rom to protect the encrypting from being brute forced. So unfortunately those devices can’t be brute forced with the method I describe but a SEP zeroday could allow this (which by the way does exist, google celebrite) Moral of the story, security is a myth. As for these tools being made public... it’s 50/50. I understand you want back into your device but.. would it really be a good thing if anyone can do this? Myself personally, I hope these tools remain private. For every good person out there theirs five bad. The needs of many outweighs the wants of a few. It’s better for all of us that those tools never get released. Anyways, sorry I couldn’t help but at least you now have a better understanding of what it’d take to actually crack your passcode.

@@CeaddL You do have a good point. Unfortunately, if this tool is given to the public there will be people who use it for malicious reasons as well 😑. I subbed to you btw.
