iOS 10.2 jailbreak could come via YaluX update

By , Jan 9, 2017

iOS_10.2_jailbreak_announcement

The creator of the iOS 10.1.x jailbreak YaluX has announced that he intends to update the tool, currently in beta, to add support for iOS 10.2. Luca Todesco tweeted that his solution for the instability of the early builds of his tool has tangentially allowed for compatibility with the most recent firmware, news which will no doubt delight many in the jailbreak community who are trapped on iOS 10.2, and who have been lamenting the death of the jailbreak on currently signed firmwares.

Before you click your heels and start popping corks, there is one major caveat to this piece of news: the support for iOS 10.2 will not extend to the iPhone 7 and iPhone 7 Plus. Whilst this is disappointing for owners of those devices, there is a good reason for the lack of support. It seems that Todesco’s 0-day vulnerability which he gave up to make the iOS 10.1.x jailbreak, a KPP bypass technique, does not work on the iP7(+) on iOS 10.2. This may be due to this model’s superior hardware security measures.

As you can see from this image, Todesco’s changes will allow root access on the iP7(+) on iOS 10.2, which is better than nothing, but will not work fully enough to provide a complete jailbreak on that device/firmware combination.

What we must bear in mind with this news is that the main aim is to bring stability to the tool; that is why Todesco is employing a different technique. The 10.2 support is simply a happy side effect of this change. So, for iP7(+) users at least, it may be more comforting to look at this announcement as one of upcoming stability for their 10.1.x jailbreak, rather than a missed opportunity for a 10.2 jailbreak. All other 64-bit devices should be compatible with the tool on 10.2 (as well as the previous firmwares of 10.1.x).

It seems that the instability problems with the beta tool, most notably with the behaviour of SpringBoard and Cydia Substrate, may have been inherited from, or indirectly caused by, Ian Beer’s Project Zero code. It is possible that this has necessitated an additional exploit to be used by Todesco in order to work around these problems, and this is what has allowed the broadening of firmware compatibility along with the stability improvements. If so, it is good of Todesco to make use of additional exploits to bring these advancements, though of course this may not be the case.

Hopefully we will see a version of the tool with these new amendments released soon, in order to beat the iOS 10.2 signing window. Jay Freeman (Saurik) has commented that he believes Todesco’s new approach will work, which is generally an encouraging sign.

For now, I would recommend anyone on iOS 10.1.x to remain where you are. In the unlikely event that this release does not happen or has problems, you will still be safe on iOS 10.1.x and can use the existing tool, along with any updates it receives. If you want to be well prepared, simply download the iOS 10.2 IPSW for your device, and when reports of the 10.2 tool’s release and stability are confirmed, you can then use it to restore your device before iOS 10.2 goes unsigned.

If you are on a lower jailbroken firmware such as iOS 9.3.3, the same advice applies. Prepare your IPSW, and wait on your lower firmware until the tool is ready.

I would also recommend everyone to save their iOS 10.2 blobs with TSSChecker/TSSSaver. It is general good practice, and has been advised by Luca Todesco more than once. It could, in some limited cases, serve as a way to get back to iOS 10.2 in future.

Have you got your IPSW ready? Are you excited at the possibility of a signed firmware jailbreak? Pray tell.

    Iphone 7 plus user on 10.2 so this means nothing to me sadly.

  • Obada Essa

    And still no jb for iPhone 5/5s/6(Plus) on 10.0-10.1.1.. I own an iPhone 6 Plus 🙁

    • Joaquim Barbosa

      iPhone 5 is 32-bit, so that’s a different issue now. It’s much less likely to get any attention. Support for iP5s/6(+) is coming, as has been said many times. Luca Todesco is re-writing the tool, and will then add support for 64-bit devices. It will be released soon with some luck. Thanks.

      • Arjan Vlek

        Why is 32 bit never supported anymore? Is it really that much harder to provide a jailbreak for 32 bit devices as well? These devices being older, it is likely they are less secure, isn’t it?

      • Joaquim Barbosa

        I think it is more that the vulnerabilities are often different on 64- compared to 32-bit. This means that to support both requires more work, and also more exploits, which are valuable. But the biggest issue now is that very few of the people who will actually make a jailbreak use 32-but devices anymore. So there is no interest/pressure/testing for those devices. In addition, very few 32-bit devices even run iOS 10 well now, and many stop at 9.3.5 anyway. Overall, it’s just an unfortunate case of them becoming unsupported legacy devices I think. I personally just want to see a 9.3.x jailbreak for 32-but, up to 9.3.5, and then to leave it there… Thanks for reading!

      • Arjan Vlek

        I understand. However, it would be great to see, when apple makes iOS 11 which likely requires a 64-bit device, that there will be one final jailbreak release wich ‘breaks all 32-bit devices 4 life. Either on 9.3.5 (iPhone 4s, iPad 2, iPad 3, iPad mini 1, iPod touch 5) or on the last iOS 10 release (iPhone 5, iPad 4). There was a video of a jailbroken iPhone 5 on iOS 10 beta, via some sort of boot loader exploit. I hope they’ll hold on to that exploit for this hypothetical final release…

  • MrE23

    I can’t get TSS Saver to save my blobs. I get an error message: Invalid ECID! (HEX)

    The ECID is correct, the iPhone version 6S is correct and the board model N71AP is correct.

    Very frustrating 🙁 Awaiting reply from 1Conan on /r/jailbreak…

    • Joaquim Barbosa

      Hmm, that’s odd. Does your ECID have no letters, only numbers?
      You could try using TSSChecker instead if you’re comfortable with Terminal commands.

    • TK421

      You could also try the telegram method. it’s posted on Reddit jailbreak

    • had3z

      Are you positive what you have is correct. Have you tried the iTunes method to get your ECID. Doesn’t hurt to check again 😉

  • Rondog

    Great to know that a jailbreak may be possible soon, I wouldn’t lose hope if you have an iphone 7, a lot can happen between now and the public release. We have to remember that Luca has been adding different iphone versions, so who knows? Tadesco is a great jailbreaker and nothing can come as a surprise. We just have to let him do his thing.

  • David Gow

    Waiting patiently. Thanks to all for their time and patience. Happy New Years to all
    Ip6+ 10.1.1

    • Joaquim Barbosa

      And to you David!

    • David Gow

      Yes I was jb but alas I had to restore

  • Blip dude

    This is some welcomed news. Especially after finding out that my out of warranty iPhone 6S Plus is going to cost me $329 to replace (Bluetooth and NFC issues), so assuming that the new iPhone I get is still 10.2 I’ll be good.

    • Joaquim Barbosa

      With luck, you’ll be ok. We’ll have to wait for release to know for sure, but it seems like you’ll be fine. Just don’t upgrade to a 7(+)!

  • Micki

    lol so he totally skipped the IOS 10.1.1 jailbreak for the iPhone 6!

    • Supah Hollywood

      No he didn’t ; adding 10.2 was just coincidentally he is still working on bugs for it to work well with 5s/6/6+
      He could drop it now but then you’d be on here complaining you had to restore

  • Steve Harold

    What about 10.2.1

    • Supah Hollywood

      No

      • Steve Harold

        K I’ll downgrade via an update in iTunes

  • John

    Not really sure if 32-bit devices will get jailbreak on IOS 10 ever. I own an iPhone 5, should i stay on 10.1.1 and wait for a (unlikely) jb o just update to the last IOS version? ☹️

    • Joaquim Barbosa

      In general, lower is *always* better. Unless a trusted developer has said “update before signing window closes, I have a tool for X version” you should always remain on as low as possible. More bugs = better chance of jailbreak. Having said that, I agree that it may be a while before we see an iOS 10 32-bit jailbreak. Thanks for reading!

  • Mark S

    Thanks! Got my 10.2 downloading now…..

  • I really hope it will be an untethered jailbreak.

    • Agneev Mukherjee

      How so? The headlines state “YaluX update”, so it’s an update…

    • Joaquim Barbosa

      I’m almost sure it won’t be Prasoon, YaluX is semi-(un)tethered and the new version will almost certainly be similar. Cheers!

  • Diego Milano

    What exactly do you mean by “prepare your IPSW”? You mean just downloading it or doing something else with it? Also, my understanding is there is a site to get all of these IPSW, or maybe I am confused and they are just pointing all of them to the original source (Apple) much like iDB does, but I thought there were mirrors?

    • Joaquim Barbosa

      Yes, I mean just download the correct one so you don’t have to download it later, with the signing window running out. You will just be able to select the file in iTunes and away you go. Firmwares can be found here:

      Yes, all the sites point to Apple, the same as iDB.

      Cheers!

      • Diego Milano

        Cool, thanks. I’ll grab it later today then.

  • guy4jesuschrist

    I’m on a 6s Plus, 10.0.1…I’ve seen conflicting information that the current jailbreak doesn’t/does work on 10.0.x–10.1.1. Is this correct, or should I update to 10.2? I’ve asked Luca on Twitter and searched for the answer, but haven’t found it yet.

    • Tim

      For iPhone 6s Plus the jailbreak will work on iOS 10 to 10.2

      • guy4jesuschrist

        I tried to respond to both yours and Joaquim’s comments, hoping it’d post my reply below your replies, but it didn’t, so I figured I’d let you know that I responded to y’all above.

    • Joaquim Barbosa

      For 6s it should work on all iOS 10 up to 10.2. However, please wait until the tool is released before you move to iOS 10.2, just to be safe. Thanks.

      • guy4jesuschrist

        I tried to respond to both yours and Tim’s comments, hoping it’d post my reply below your replies, but it didn’t, so I figured I’d let you know that I responded to y’all above.

  • Y2J: Keeper of the List

    Pretty pissed that I waited on my 6S+ and didn’t update but Sprint gave me a great deal on a 7+ and it came with 10.2.

  • Natalie

    So, Got screwed over by the SHSH2 blobs not actually being saved on the iPhone 7, now this. LOLs. Rip Jailbreak.

    • Joaquim Barbosa

      That is unfortunate, I agree. However, it would always have been advisable to stay on a lower firmware like iOS 10.1.x instead of just saving the blobs and moving to 10.2, as this is always best practice in jailbreaking. Hopefully we’ll see a 10.2 tool for iP7 at some point though, don’t upgrade any further! Thanks

  • T. Allen

    I’m on 9.3.3. I need to download the 10.2 IPSW NOW. Is that part of what the article is saying? If so, that’s cool. But what about saving my blobs? I cannot save 10.2 blobs if I’m on 9.3.3…..right??

  • aced

    I personally would like to ask what are the chances of a iOS 9.3.5 jailbreak on a 5s/6/6s? I missed my chances of getting onto iOS 10.1 because of a lack of checking idb but whatever it’s my loss, but what are the possibilities for the people stuck on iOS 9.3.X? Will this be a possibility or a waste of time?

  • djluna31

    I need to jailbrake my iPhone 6 please when is going to be available please tell me

  • aizathisyam

    I’m currently on Ip6+ 9.3.3 JB… Should I stay or will YaluX support Ip6+ on 10.2?

  • Just bought a 7+ where it’s not officially sold I thought it’d be on 10.1 but unlucky its on 10.2

  • bung

    is it working on ipad mini 4 10.2?
    thanks
