Hot on the heels of the source code being posted to GitHub yesterday, Luca Todesco has posted a very early build of the tool to his website. Work on the GitHub code proceeded quickly after its posting last night, with Todesco and others merging several commits to enable Substrate, add more device support, and streamline the tool.

About the tool

The tool currently sits at Beta 1, and as such is not to be expected to be perfect. It likely still has many bugs, and does not yet support all 64-bit devices. However, Todesco has commented that due to the new methods it uses it should be more stable already than the Beta 3 of his previous tool, which was for iOS 10(.1(.1)).

Current device support extends to:

  • iPhone 6s
  • iPhone 6s+
  • iPhone SE
  • iPad Pro

Community members have added offsets (which provide support for other devices) to the code but they do not work yet, as the code needs further modifications from Todesco. He has stated he will not be able to make those changes until at least the weekend, as he needs to be able to test on those devices. This includes all 4k devices (memory page size, not screen resolution), which is every device earlier than and including the iPhone 6. It is for this reason that the supported device list at the moment is restricted to 16k devices. Once Todesco has updated the code, the offsets added already by others will bring the iPhone 6 and iPhone 5s into the fold, with other 64-bit devices joining as their offsets are added.

This edition of the tool should work on all iOS 10 versions up to iOS 10.2 for the devices listed above. It does not currently work for the iPhone 7 or iPhone 7 Plus, but when it is finished it will support them on iOS 10 versions up to iOS 10.1.1, but not iOS 10.2. All 64-bit devices are expected to be supported eventually.

Should you use it?

Yalu for iOS 10.2 already has Cydia Substrate enabled, without the dubious hacks which people were employing on the previous betas, and should offer more stability than the previous betas too. Whilst I personally would wait a few days for stability reasons, it should not be too dangerous to try out the tool now, only if you have a supported device, and while iOS 10.2 is being signed. Before the iOS 10.2 signing window closes, I would recommend returning to stock iOS 10.2 and awaiting a final (or at least gamma) release, though of course, this is up to you. You should be able to move up through the releases without a problem.

Currently, the tool can only be installed by downloading it from Todesco’s website and then side-loading it onto your device using Cydia Impactor. You will need an Apple ID for this. If you are unsure as to how to go about this, give it a miss for now. I will be posting a guide on how to install the tool soon!

In the meantime, if you’re unsure as to what OS version you need to be on or what course of action to take, check out my updated guide, which talks through all the options you have as regards updating, restoring, and jailbreaking.

  • Alan Zhao

    Does it work with iPhone 7 10.0.x

    • Joaquim Barbosa

      Read the article man. It doesn’t yet, but it will.

    • Alex Best

      yes.but wait for couple of days till public version come out

  • Rodney Coleman

    Just updated to 10.3 beta…..

    Guess I’ll wait until the next jailbreak.

    • Tom M

      downgrade to 10.2.

    • Alex Best

      go buck to 10.2 now man! noooooow! 😉

    • Joaquim Barbosa

      You can downgrade to 10.2 now if you like. Or do you have an iP7(+)? If you have any device other than iP7(+), downgrade to 10.2 quickly, and you can still jailbreak…

      • Val

        how to downgrade to 10.2? i have iP6S+ 10.2.1..

      • Νίκος Τιτομιχελάκης

        Just download ipsw 10.2 and restore the file holding shift on windows

      • Val

        yup got it. i remember using that method. thank you.

      • Joaquim Barbosa

        Yes. Download the iP6s+ IPSW for iOS 10.2 from our downloads page. Make sure you download the correct one for your device model. Then, in iTunes, hold down “alt” (Mac) or “shift” (Windows), and click on the “Restore” button. Then select the IPSW file you downloaded to restore to 10.2. Do not restore to 10.2.1 by mistake.

      • Val

        got it thank you!

  • Javier Gore

    Awesome. This is finally taking shape of a public 10.X Jailbreak. Glad I stayed at 10.1 on my iPhone 7

    • Joaquim Barbosa

      Yup, perfect place to be. Now just wait for a stable release for iP7 and you’ll be set.

    • William Melendez

      Tell me about it. I was getting tempted to download 10.3 beta 1 lol.

      • Devgru

        If ur tempted jack it.. And go back..
        .

      • William Melendez

        No, I can’t. I have the 7 plus and I’m currently on the 10.1.1.

  • Alex Best

    Lucaaaaa! 5s suport? ??? please.

    • Joaquim Barbosa

      Read the article. It’s coming, but not before the weekend. It will support all 64-bit, but needs changes for the 5s.

  • No i6+

  • I’m so glad I didn’t update my iPhone! Going to wait a while until the jailbreak is out of beta.

    • Joaquim Barbosa

      Good plan. What device/iOS are you on?

      • Diego Milano

        Me too, even though it’s tempting to update but since I can’t jailbreak iOS 10.2 on iPhone 5s, I’ll have to pass since I cannot test this before deploying this into my main device (iPhone 6s Plus).
        I just hope Prometheus works!

  • Tom

    Is it stable enough to JB? Or should I wait for the next build?

    • Joaquim Barbosa

      I’m putting together a how-to guide now. But I’ve already restored to stock. I think it is probably safe enough to try out if you want, but for the sake of a few days I prefer to wait on stock and start with a stable build from a clean slate. Up to you though!

      • Tom

        Thanks!

  • Ruck

    Ok so can we load this, and not have to do the steps of the mterminal chmod?
    So do we need to still do the mach_portal hack?
    Also can we do this when only on 10.1?
    Thanks

    • Joaquim Barbosa

      Please read my articles, they answer all your questions. It depends what device you have, whether you can do it or not. You didn’t mention your device. No, with this you do not need mach_portal hack or terminal commands. Cheers!

      • Ruck

        Sorry, I have a 7s Plus. So I assume I can’t even use this yet, from what the article said. I am just getting real tired of the chmod commands everytime it reboots 🙂

      • Devgru

        Don’t try.. It will soft brick ur device..

      • Joaquim Barbosa

        You will have support on 10.1, not on 10.2 if you have an iP7(+). So stay where you are. You will not need commands.

      • Ruck

        Ok I’m confused. From what I read.

        Every time I reboot, I need to do the following:

        Do the mach_portal patch
        Then do all 4 chmod commands.

        So even if the phone reboots on its own, I need to do those two steps.

        Is that correct?

      • Joaquim Barbosa

        No, you only need to do the first step on every reboot. The second step is just once after loading the tool onto your phone. And on the 10.2 tool you won’t have to do that even once. You only have to use the app once per reboot, nothing else.

      • Ruck

        ugggg so I have been doing that each time. LOL…oh well. I know them by heart now 🙂

    • Alex Best

      do nothing ! wait

  • Aviorrok

    iPhone 7 plus jailbreak iOS 10.1.1 or wait for stable jailbrwak or update to iOS 10.2 and wait for jailbreak?

    • Joaquim Barbosa

      DO NOT GO TO 10.2. STAY ON 10.1.1. Stable jailbreak for iP7+ is coming on 10.1.1. NOTHING IS COMING ON 10.2 FOR IP7+.

      • Aviorrok

        Thanks!
        Time to updates my themes

    • Alex Best

      10.1.1 stay !

    • Al Fresco

      Hard to tell. I’m in the same boat. I was just about to update to 10.2 but then I saw this article and aborted the process. I really hope this jailbreak is untethered.

      • Devgru

        Its semi not unthetherd.. Semi is best of both world.. U can enjoy non jail broken and jail broken in same device.. Cheers

      • Joaquim Barbosa

        It’s not untethered, but 10.2 will not get iP7 jb support, only 10.1.1. Cheers.

    • Devgru

      Stay on 10.1.1..

  • Steve Harold

    It says has Cydia substrate, but does r have the actual Cydia app?

    • Joaquim Barbosa

      Yes, it does.

    • Devgru

      Both.. Cydia with sudstrate enabled

  • Allstarz_Black

    I’m on 9.3.3. Any luck for me?

    • Joaquim Barbosa

      You can already jailbreak 9.3.3 on 64-bit devices. What device do you have?

      • Allstarz_Black

        True. I’m jailbroken on an iPhone 6. But I want to be jailbroken on iOS 10.

      • Joaquim Barbosa

        If you’re techie you can save 10.2 blobs quickly now with TSS Saver, and upgrade later, even after 10.2 stops signing. But if that sounds too complicated, jump to 10.2 quickly now. iP6 will be supported soon. Up to you.

      • Martin

        dont! my biggest regret

  • Guilherme 

    i5s iOS 9.3.3 here. Should I stay or should I go to 10.2 right now?!

    • Martin

      stay

      • Mark S

        go

    • Joaquim Barbosa

      Check out my guide:

      http://www.idownloadblog.com/2017/01/25/ios-10-2-1-jailbreaking-what-are-my-options/

      iP5s will be supported on 10.2 soon, so it’s up to you whether you stay on 9.3.3, switch now to 10.2 and wait, or wait on 9.3.3 and switch later with Prometheus. The last option is harder though and you must save shsh2 blobs NOW if you want to do that. Cheers!

    • Mark S

      Should I stay or should I go? Da da da da da da da da. It’s always tease tease tease….

      • Guilherme 

        Hehehe that was intended

  • Max Barlow

    It’s not beta, it’s alpha

    • Joaquim Barbosa

      Turn of phrase, but yes, you’re right. Although he called the first three for 10.1.1 betas, and he has said this build is more stable than them already, so maybe they should have been called alpha, and this beta. Who can say…

    • Devgru

      Its beta not alpha.. Just he add support for 10.2..

      • Joaquim Barbosa

        That’s not the only difference. This is technically a different tool to the other one with different methods. It has support for 10.2 because it is slightly different, not the same.

  • Mohammad Dika

    Guys im on ios 10.1.1 on ip6 do i stay or do i upgrade or lose hope entirely cause so for for both 10.2 and 10.1.1 ip6 isnt supported

    • Joaquim Barbosa

      Upgrade to 10.2. It will be supported soon.

      • Mohammad Dika

        On 10.1.1 it wont?

      • Rigs101

        It will be supported for your device but Apple introduced new things on iOS 10.2 so I would recommend updating to iOS 10.2 since it will have new features and some bug fixes over 10.1.1

      • Mohammad Dika

        Agreed. Thanks

      • Devgru

        What wont

  • Rigs101

    Is this tethered? Semi? Or untether? I haven’t jail broken my iOS device since iOS 8.4, but now I miss 3Gunrestrictor

    • John Smith

      It’s really interesting how many forget to mention this, it’s literally the most important aspect of a jailbreak.

      • Rigs101

        I know for the previous version it was semi, but this article didn’t mention this at all

      • 5723alex .

        untethered.

      • Supah Hollywood

        Are you sure? I believe it’s semi

      • Devgru

        It’s semi thetherd..

      • Devgru

        Its semi thetherd..u can rejailbreak by phone its self and U don’t want computer to jailbreake every time ur device restart or switch on.. Its thetherd one

    • Digitalfeind

      It is semi

    • Joaquim Barbosa

      It’s semi-(un)tethered. People don’t mention it because many articles have been written about this tool already, it’s basically the same as Luca’s one for 10.1.1. And all recent jailbreaks have been semi-(un)tethered because of iOS security. From now on, unless it is specified, assume all releases are like this on newer firmwares. Cheers!

    • Reilitas

      I wonder if we’ll ever see another untethered jailbreak. I’m here with my iPad Air jailbroken untethered on iOS 8.0! Now that’s an older firmware lol I remember in ancient days when 7.0 was finally going to be a thing, and that it would change the face of iDevices forever. Before Control Center was a thing we were all waiting and waiting for the feature!

  • LosTiraPiedra

    so i cant jailbreak with iphone 7 10.2? >.<

    • 5723alex .

      NO

    • Devgru

      Yes 100 %

    • Joaquim Barbosa

      No, you can’t, sorry.

  • David Gow

    When I check my phone for update it says 10.2.1 is available. I think I should wait to get home to update to 10.2 on iTunes or is already to late to update to 10.2. I know it’s a silly question but……

    • Joaquim Barbosa

      You can only manually move to 10.2, your phone will skip it. You must download the 10.2 IPSW manually, and restore with it in iTunes.

      • David Gow

        Thanks

  • Micki

    “Tool Wil be available to more devices soon”. Same thing he said for the other tool. And it nevertheless helped other devices. I wouldn’t keep my hopes up.

    • Joaquim Barbosa

      It still will be. This new tool IS PART OF bringing stability/support to the other tool. They’re the same project.

    • Devgru

      Respect his work first.. And its completly free of cost.. U know to release jailbreak there should be 10 to 15 exploit to burn.. U know how much it will take to find 1 exploit.. And every exploits are used in that jail break apple will patch that in future version..

      • Micki

        I do very much so. But if you release a hack tool then release the final not bit by bit.

  • jaimem17

    A few questions. iPhone 6 jb on 9.3.3 I saved my blobs using tsssaver but I am a bit sketchy about the blobs because of the touchid thing, I read from a developer that i6 support is coming soon (weekend), should I risk and upgrade to 10.2? Do you have any idea when Apple stops signing versions? like on tuesdays or so, or could it happen over the weekend? Thanks

    • Devgru

      May be in few days.. Till stop singing 10.2.. If u have blobs saved correctly u can update ur device to 10.2. And save blobs of 10.2.. Until its too late.. Hope this is last jb for ios10.x.x.. And no other teams are working..

    • Joaquim Barbosa

      The signing can stop any time. No way to predict. There will be no Touch ID problems moving to 10.2 with Prometheus, only to 10.1.1, so that is fine. You should still check your blobs are valid though if you want to do that. If you are too worried, update now. I am waiting on 9.3.3 and using Prometheus later.

      • jaimem17

        Thanks Joaquim, I believe I saved them correctly through the tsssaver site and verified the file with them. I`ll take your advice and wait, maybe next week we have i6 support.

  • aced

    Cant wait for the long list of supported 64 bit devices. Just to confirm this doesnt work on iphone 5s ios 10.2 I tested.

    • 5723alex .

      Only for iPhone 6s, iPhone 6s Plus, iPhone SE and iPad Pro running iOS 10.0, 10.1.x, 10.2.

    • Devgru

      Its open source now.. Some one will make it to every device..

  • Hùng Cường

    after i jailbroke my 6s plus on ios 10.2
    almost applications are crash.
    i dont know why?
    i need help

    • Devgru

      Hard reset ur device..

  • hudson martins

    So Next week out for iPhone 5s? Go to 10.2 or stay on 10.1.1.?

    O que vc acha, Joaquim?

    • Joaquim Barbosa

      Go to 10.2. Acho que a proxima semana vamos ver apoio para 5s, ja comecou…

      • hudson martins

        Obrigado!

      • Andrieux Querido

        Estou no ios 10.1.1 no meu iphone 7Plus. Fico nele ou update pro 10.2? Estou só esperando o JB 🙂

  • Natalie

    iPad Pro. Do you mean the 11″ or 9″ both models?

    • Devgru

      Both

  • Diego Milano

    Good advice, bud.

  • igobythisname

    Any word on if/when Cydia Eraser will get updated to work on iOS 10.x? it’s the main reason why I’m staying on iOS 9.3.3, thanks!

    • Devgru

      No word from saurik..

  • Y2J: Keeper of the List

    I’m so happy Sprint gave me a 7+ on 10.2 :))))))

    *sarcasm*

  • Rondog

    If I use this beta version of jailbreak will it affect my device when we get the final version and try to update to it?

    • Devgru

      Yes u can update.. Every beta is not too buggy.. Even non developers not able notice bugs.. If u afraid wait for stable one

    • Joaquim Barbosa

      I think you’ll be able to update without problems. I’m playing it safe and waiting for stable, but in theory you can install over the top.

  • Jason

    Ok, as far I know for now, I have iPhone 7 plus, I’m still onto 10.1.1 I have not jailbreak it yet. And I know 10.2 only support iPhone 6S not iPhone 7 plus. If I were to jailbreak 10.1.1 by using Cydia compactor and I have to rejailbreak every 7 days? As I know it’s not going to be unthreatened jailbreak semi-unteathered. How long do I have to wait for a stable jailbreak? Once they make a stable jailbreak will i still have to use cydia impactor every 7 days?

    • Devgru

      Rejailbreaking every 7days.. Hope ur mistaken.. Its semi thetherd jail break not unthetherd.. If u have iPhone 7 stay at 10.1.1 if u don’t want loose jailbresk.. When stable version released.. U can update existing jb..

      • Jason

        Thanks!

    • Joaquim Barbosa

      You will still have to re-jailbreak every 7 days unless you have a developer account I think. You won’t have to wait very long for stable I don’t think.

      • Jason

        Thank you for your reply. Fingers crossed!

  • jalexcarter

    “but when it is finished it will support them on iOS 10 versions up to iOS 10.1.1, but not iOS 10.2.”

    soooooo if 10.2 is not going to be jailrbreakable with this tool so why the heck is it named yalu for iOS 10.2? Is it just me or is this really confusing? guess ill keep my iphone 7 on 10.1.1 for now unless someone from iDB would like to clarify

    • Joaquim Barbosa

      It’s for 10.2 for all devices EXCEPT ip7. So ‘Yalu for 10.2’ is pretty much correct. One device can’t dictate it’s name for the entirety of the rest. The iP7 is an exception not the rule. It will work on 10.0-10.1.1 for iP7 though. Cheers!

      And yes, to clarify, ip7(+) stay on 10.1.1, everyone else 64-bit, go to 10.2.

      • Devgru

        Its only for 6s,6s+.5se, both iPad pro.. Not all 64bit device

      • jalexcarter

        oh okay, that wasn’t very clear in the article, thanks for putting it in lamens terms for me!

  • Jimmy Carter

    I have a iPhone 6 on iOS 10.1.1 do I need to go up to 10.2 or stay on 10.1.1

    • Reilitas

      Never update it. You’re on the REAL gold master!

    • Joaquim Barbosa

      Go to 10.2 while you can. Thanks!

  • David Gow

    I take great care to remind me later from apples about new updates to iOS. Somehow my phone is trying to update to 10.2.1 I was on wifi and turned it off. Is there anyway to cancel the update
    This sucks because I was on 9.0.2? – And had a great jb I used impacter or the latest one from surik but it didn’t work and had to update. I don’t think I can wait another three years for a jb. Any ideas would be appreciated

    I miss my tweaks and thanks again for the hard work

    • Rodney Coleman

      No one is ever any help here lol

      Go to settings>storage>and delete the update

      • David Gow

        Cheers

  • Rockwell

    Jailbreaking has become a straight ish show.

  • Reilitas

    I wonder.. why hasn’t there been anything for the iPod Nano? lol

  • Josh Venegas

    so will this not work on iOS 10.2.1?

  • Endriu Andrei

    Iphone 7 iOS 10.1.1 here . Should I stay here or update to 10.2 ?

    • Iskren Donev

      iPhone 7/Plus owners should stay on 10.1.1.

  • Lola Loredana

    iOS is shit. Whit or no jailbreak.

  • nvog

    What it really takes to have a decent, like good old times, UNTETHERED jailbreak, with no expiring certificates, reboots, and other shit ??????

    Maybe a donation or something ??? Speaking for myself…. I’d give it gladly to have a similar to 8.4 or 9.0.2 jb.

  • Alex-V

    is there still a problem that in app buy is a no go ..?

  • getzufreezed

    will this Yalu Jailbreak tool work on iPhone 6 Plus as well? It says all 64 bit but iPhone 6 Plus is not mentioned explicitly. Thanks for the help.

  • David Gow

    Sweet. No problems swipe selection pro first tweak. Thanks to all the people again

  • This is why I’ve got a brand new 7+ sitting in a drawer doing nothing and still using my 6S+. None of these new jailbreaks are stable or convenient and until someone cracks 10.2 I’m stuck on 6S+, but at least it works 100%!
