iH8sn0w gets a lifetime jailbreak for A5 (X) devices

iH8sn0w

iH8sn0w has found a security hole on the A5 and A5X processors of iOS devices. With this you can get a jailbreak for life, forever.

Even so, it must be indicated that This is not a bootrom-level jailbreak, but an iBoot jailbreak, there is a lot of confusion on the net about this type of exploit and about its future, there will be a jailbreak forever but these devices will be forced to use custom firmwares, it is not like the iPhone 4 jailbreak that cannot be closed. We tell you everything below.

Before proceeding further, it should be noted that the A5 and A5X devices are the following:

  • iPhone 4S
  • iPad 2
  • iPad 3
  • iPad mini *
  • iPod touch 5G *
  • Apple TV 3 **

* The iPad Mini (original, without retina screen), the fifth generation iPod Touch and the third generation Apple TV have a different processor, being an A5 it has 32nm, it has not been clarified that the exploit works on this processor.

** The Apple TV 3 is a world apart, it has very little software, and you always need some software to shape this type of jailbreaks, being totally different and not having iOS as we know it, it is not clear that it is may jailbreak in the future. In case it could be the first jailbreak for this device.

An exploit at the iBoot level not the same as a Bootrom level exploit, the second is forever, the first is forever but with conditions. A jailbreak at the Bootrom level cannot be closed, in any way, it is in the device's hardware. An iBoot jailbreak, or Bootloader acts on a part of the iPhone software, so can be closed with a simple iOS update, but using this security hole you can update iOS without changing the bootloader, so keep the jailbreak.

To explain it in clearer terms, the bootloader is what allows to use the recovery mode of the iPhone (Recovery Mode), it is software, it can be changed, but you can also use this control on the bootloader to update with a custom firmware that preserves the bootloader as it is; if you do this with all the updates you will be keeping the jailbreak forever.

That is, if it were released it would only serve for those people who do not update naturally (from the moment of being launched), but do so with custom software. If you update by mistake naturally, you lose the jailbreak forever.

Even so I said "if it were thrown", because it looks like your discoverer is going to save this exploit for hackers to use it to find new jailbreaks in the future, it will most likely never be released.

    This means that we already have to worry more, and if it is with this version of ios that is now where is the hole that we will have to save by creating a custom? For example, for ios 7.1 you can approach a custom keeping the hole and we will already have iBoot jailbreak?

      The exploit will be open until it is released and Apple can close it, if it were released now, it would be necessary to update to 7.1 with a custom, but it does not seem that they will launch it, so it will probably remain open forever.

        Thank you for your quick response, and of course for the news that is very good news ...
        Thank you Gonzalo R.

    I keep the talent of all these characters in the jailbreak scene. They put in check again and again the all powerful Apple (one of the safest in the world). They are phenomena

    Hello, I would like to know which is the iPhone 4 jailbreak that cannot be closed, I have been with this jailbreak for a short time and I had no idea that there was a jailbreak that Apple cannot close on iPhone 4, and I would also like to know if with that jailbreak it is possible to update the phone without any problem for example to iOS 7.1 when it comes out. All the best

    1.    Gonzalo R. said

      It is called Limera1n, it will allow you to jailbreak TETHERED in iOS 7.1, but it is not recommended, better UNtethered like now.

      Take a look on Google for these terms.

    Let's see, it is good to have a backdoor, but in the end the backdoors are filtered to apple and they are patched. So if I only released now, from the current version you could update to custom firewall and in case you update to a normal one by mistake, Downgrade to this version and then use the hack to get back to custom and update to the latest version of custom directly.
    This method is one of the oldest used in plays, Xbox, psp, wii etc. downgrade to the exploit and then install the custom.
    Simple and easy, I hope you get this exploit out because it would give a new world to ios by being able to install custom firmwares more easily.

    PS: I'm from Android

      There is no downgrade in A5 (X), so what you propose is not commendable.

      If you update to a patched version there you stay.

        Alberto, you talk about the processes used with the iPhone 3G / 3GS / and iPhone 4, having the shsh, that process can only be done with ios devices with a4 chip, with the following models with chi a5 you cannot go back as it is done with the a4. You are quite confused ...
        All the best

    With these things, the usual happens: launch it so that users can enjoy it? Or save it in case it hypothetically allows discovering other jailbreaks for other devices? Risking Apple shutting it down (by chance) in a future update without anyone being able to do anything?

    Personally, and risking being wrong, I would publish it so that users of all those devices could enjoy a jailbreak on their devices forever. And I have an iPhone 5, so in theory it doesn't work for me.

    Thanks Gonzalo, I know what those terms are, then another question arises, in iOS 7.0.4 which is the one I have now with the untethered jailbreak, would a tethered jailbreak also be made or would it remain untethered? In other words, in the iOS versions that already have untethered jailbreak, if Limera1n is used, they would be left with untethered or with Limera1n, only tethered jailbreak can be performed?

    1.    Gonzalo R. said

      In 7.0.4 the jailbreak is done through an outright software exploit, it is therefore untethered.

      If it were done with Limera1n (in fact it could be done since iOS 7.0 came out) it would be tethered.

      1.    VVG said

        Ok thank you very much for the info, I will take it into account when iOS 7.1 comes out

    2.    robcourret said

      In fact, if you have iOS 7.0.4 and you jailbreak it with Limera1n, it will be Tethered, but if you do it with Evasi0n 7 you will have an Untethered jailbreak.

    Hello, I have an Apple TV 3 with the latest software version
    Will it be possible to jailbreak to install third-party software?

    1.    Hercules said

      For now there is nothing jail for apple tv 3 gen.
      It remains to wait for this device, always abandoned by hackers

    When will they release a jaybreak for apple tv 3, will they release it?
