    Just curious as to why they can jailbreak every other device, but not this one? Does it have a different file system, something specific in the hardware, etc.?

    Just seems it's been out awhile, and these guys seem to be able to turn a box of milk into a camero with their computer skills, yet can't seem to get this one done.

    Any ideas?

    They haven't found exploits to allow the jailbreak.

    It's a combination of the newer CPU & much less of a filesystem surface to work with in finding an exploit. The ATV2 can rely on a hardware exploit whereas the ATV3 does not have the same

    I understand that part, but why (how?) can they find exploits for both newer and older devices than the Apple Tv3 but not specifically it?

    Meaning, I get what the next poster said about the hardware exploits, but what makes it so hard to find the software ones when they seem to find these exploits everywhere else?

    ATV3 uses a modified A5 chip which has proven to be difficult, if not impossible, to hack.

    I understand your plea.

    But that does not change the fact that the exploits just are not present.

    Since you seem to represent that the best hackers have failed in some way, I challenge you to figure out a method to inject a jailbreak into the modified A5 chip.

    The reason that jailbreaks exist for devices newer than Apple TV 3 is because more people own/use those newer devices. Apple doesn't sell as many Apple TV 3s as iPhone 5s, iPad 4s, iPad minis, iPod 5th, etc.

    It is impossible to comprehend the incomprehensible.

    ----------

    The presence or absence of exploits in a device is not a function of sales.

    I have no idea how to create an actual jailbreak. My comments were not made as a challenge or whatever. I was curious as to the actual reasons (not just "its been discussed" or "it has different firmware") why it was so difficult to jailbreak. When people seem to be able to mod nintendo, sony, apple products, etc. and the jailbreakers continuously jailbreak new devices, new chips, new firmware, I was just curious as to what made the ATV3 so special that nobody seemed to be able to break it. ie. ATV 1 and 2 were done, iphones have all been done, but this one device seems so elusive. I would think it would be a goldmine for someone to jailbreak.

    In lay men's terms, the iOS isn't as "robust" or as "big" as the iOS on all the other devices. The hacks used for a jailbreak don't work on the atv3 because the areas were these hacks "attack" simply don't exist on the atv3. The hackers referred to the atv3 as "not having as large of an attack surface".

    This is what dhlizard means when he says the hacks "simply don't exist". He's absolutely right. The hacks used for evasion and absinthe can't be used on the atv3 because the areas of the iOS where these hacks occur "simply don't exist" on the atv3 firmware.

    Edit: I just realized I misquoted dhlizard. I'm not gonna fix it because the larger point remains. I hope this helps.

    You're welcome. Sorry its not technical or detailed at all. But that's the gist of why the atv3 does not have a jailbreak and prolly never will :(

    There isn't a jailbreak because no one is working on the atv3 that's the only reason, if the evaders were interested in jail breaking it it would be jailbroken!
    Anyway why don't you just install XBMC on your iPhone / iPad / or mac, and just AirPlay it to the atv3?

    Do you really know which of the hackers have worked on the ATV3 ?

    I am aware of some who have (core members of the jailbreak community), and as already stated, the exploits to support a jailbreak just are not there.

    Your claim is incorrect !

    Alls you had to do was search that name in this forum and it would turn up zero results, therefore confirming its fake.

    This is as good as it can get. Even if you were to put it into a more technical explanation, I am sure OP would be clueless about it.

    No one ever said you are a retard. It's normal for someone that doesn't do programming/hacking to understand the technical aspect of JB. If you are into programming/hacking then you would not be asking it here because there are better website for it. So the explanation given to you is as good as it gets.

    Let's explain the famous jailbreakme website. Here is how it is done. This comes from another site that explains about it. Do you understand?

    I'm wondering whether to just keep on waiting or to buy an apple tv or some cheaper android device. I only really want for XBMC to watch sky sports and 3pm kick off football matches. Is there an android alternative that can do this as well or better than atv2 for a much lower cost? I would also like airplay but can sacrifice this is it's worth it. Atv2s are now going for £220. I'd be really annoyed if I got one and then atv3 was jailbroken within a few weeks or even 2 months - left with an outdated gadget that is probably worth 1/4 of what you paid for it. Not ideal. On the other hand I could be left waiting for a year or more. Then I would be equally annoyed that I hadn't bought one. Probably damned if I do and damned if I don't. :mad:

    Its because apple is now shipping code without (or rather, with less) serious memory management bugs in it.


    I've been saying jailbreaking may go away for a little while now... and the reason is mostly due to apple overhauling their development tools and the new additions to objective C. Specifically: ARC - automatic reference counting.


    Short version (without getting into too much developer type detail): memory management on objective C is a lot harder to screw up now, with ARC (compiler manages memory for you automatically) and the new compiler toolchain (LLVM/clang - clang generates far better diagnostic messages than GCC - warning of potential unsafe code and possible bugs, also).

    Memory management bugs are typically how software is hacked.

    No memory management bug = a lot less likely to find an exploit.


    This is one of the things that most end users will have no idea about and just don't appreciate changes under the surface of OS X Mountain Lion and onwards, and iOS6 onwards.

    They look mostly the same, but internally the code has been heavily cleaned up - mostly helped by the new compiler and new objective C feature: ARC.

    It's also a major reason I am so "pro" mountain lion and onwards. The new technology under the hood (so to speak) is a huge win for security.

    Also the ATV3 is probably more secure than an iPhone or iPod because it is more purpose built and less versatile. All the content that typically hits it is off the app store, and so it's harder to throw maliciously crafted data at it. It doesn't even do PDF or web browsing for example so there's 2 programs that will never be exploited straight up....

    I highly doubt the ATV3 is getting jailbroken any time soon, if ever. I wouldn't hold my breathe. Either buy an ATV2 or some other device.
