Update: tvOS 11.1 and iOS 11.1.2 are now unsigned.


New exploits for iOS 11.1.2  and below have made the possibility of upcoming jailbreaks very real. However, without the proper preparation, you could be left in the cold, without blobs to restore, or on the wrong firmware. Also, not everyone should update, so you need to be sure it’s for you. Let’s go through the options.

Should I save blobs?

Yes. Everyone should save blobs, regardless of device or current firmware. You never know when a new tool will let you use them, and they may save your bacon. People who should especially save them are those who are already jailbroken, or who are waiting on iOS 10.3.x for a v0rtex/Saïgon jailbreak. They may be able to move to iOS 11 later using them, and have the best of both worlds. This is not certain however. If in doubt, save them now. If doubtless, save them. We have a guide on saving blobs.

I’m on iOS 11.2 at the moment

Downgrade immediately to iOS 11.1.2 while it is still signed. You will need to download the firmware manually, connect your device to iTunes, alt-click Update or Restore, and select the downloaded iOS 11.1.2 .ipsw. On Windows, a shift-click is needed instead. Do not simply click Restore/Update, as this will take you to iOS 11.2, which we do not want.

Once on iOS 11.1.2, follow my guide to stop your device from updating, and wait to see how the jailbreak progresses.

I’m on iOS 11.1.2 already!

Stay where you are! That is perfect. Follow my guide to stop your device from updating, and wait to see how the jailbreak progresses.

I’m on iOS 11.0-11.1.1

These firmwares should still be supported by the exploit, but since you can, why not upgrade immediately to iOS 11.1.2 while it is still signed? You’ll still be covered, and you can grab the extra features and bug fixes at the same time. To do so, follow the section entitled I’m on iOS 11.2 at the moment.

I’m on iOS 10.3.x

This is the only legitimately tough one. The vulnerability used in Ian Beer’s iOS 11.1.2 exploit has already been made into another exploit by Siguza, called v0rtex, for iOS 10.3.x. There is not really much to choose between them in terms of jailbreak. I personally would stay, as the Saïgon tool already exists to host v0rtex, v0rtex is being heavily worked upon, and iOS 10.3.x may offer more of the bugs which are still needed to finish off a jailbreak. However, if you just have to have iOS 11 and believe both exploits will become a full jailbreak, follow the instructions in the I’m on iOS 11.2 at the moment section.

If you have an iPhone 5s, an iPad mini 2, an iPad mini 3, or an iPad Air (1) AND you have blobs saved for a jailbroken iOS 10 firmware, do not update. You can use futurerestore with your blobs and v0rtex to downgrade to an iOS 10 jailbreak, such as Yalu.

I’m on iOS 10.0-10.2.1 jailbroken

If you’re on any of these firmwares, have already consulted our Can I Jailbreak? guide, found you can jailbreak, and done so, then stay where you are. Do not exchange a current jailbreak for a possible future one. Unless you want to of course, in which case, we accept no liability.

I’m on iOS 10.0-10.2.1 on an un-jailbreakable device/firmware

If your device wasn’t covered by the early iOS 10 jailbreaks and fell through the cracks, then you might consider upgrading by following the instructions under I’m on iOS 11.2 at the moment. An exception would be users on iOS 10.2.1 with a device that is expecting Saïgon support. For the other niche groups who missed their iOS 10 jailbreak, like non-iPhone 7(+) users on iOS 10.0, I’d say the time has passed and you should just upgrade to iOS 11.1.2.

I’m jailbroken on a firmware below iOS 10

If you’re happy with your current level of app support and compatibility on iOS 9, 8, 7, &c. feel free to stay and enjoy your jailbreak, which may even be untethered. If however you’re beginning to feel excluded from your favourite app updates and the iOS feature-set, now might be the time to consider moving to iOS 11.1.2. Follow the instructions under I’m on iOS 11.2 at the moment.

If you have an iPhone 5s, an iPad mini 2, an iPad mini 3, or an iPad Air (1) AND you have blobs saved for a jailbroken iOS 10 firmware, do not update to iOS 11. You can use futurerestore with your blobs and v0rtex to move to a full iOS 10 jailbreak, such as Yalu.

I have a 32-bit device, what about me?

If you have a 32-bit device un-jailbroken on iOS 10.x, stay where you are. v0rtex can technically support you all the way up to iOS 10.3.3, it’s only a matter of time.

If you have a 32-bit device on any firmware below iOS 10, you can jailbreak already! Do not update in hopes of a jailbreak when you already have one. Besides, you can just wait there until v0rtex is finished, and then update.

Apple TV and tvOS

If you have an Apple TV 4 on tvOS 11.2, downgrade immediately to tvOS 11.1. Our guide on the topic, along with the tvOS 11.1 .ipsw, should do it. Once on tvOS 11.1, block updates with a nifty method.

If you have an Apple TV 4K on tvOS 11.2, you’re screwed. Sorry.

If you have an Apple TV 4K or an Apple TV 4 on tvOS 11.1, stay where you are! Block updates with a nifty method.

If you have an Apple TV 4 on tvOS 9.0-11.0, move immediately to tvOS 11.1. Our guide on the topic, along with the tvOS 11.1 .ipsw, should do it. Once on tvOS 11.1, block updates with a nifty method.

If you have an Apple TV 4K on tvOS 11.0, stay where you are! Block updates with a nifty method.

If you have any other Apple TV, nothing to see here I’m afraid.


In summation, everyone on every device, on every firmware, should periodically save blobs for every new firmware. Other than that, the general rule is that jailbroken users should stick, and non-jailbroken users should move to iOS 11.1.2 where possible. There are exceptions though, so read carefully. It is on iOS 10.2.1-10.3.3 that the hardest decisions lie, as those users must choose between two unreleased prospects. I advise staying, but it will be a personal decision. For more background, and in some cases even different options, I recommend you check out our full Can I Jailbreak? guide. It has more nuance and exposition.

    Does 11.1.2 have a bug that makes It reset on a certain date ? I am on 11.1.1 should o upgrade to 11.1.2 ? Thanks

    • ChrisLinke

      I’m in the same boat, I commented on a previous post and got no response.. after doing research, it seems the bug isn’t on all phones, and also applies in very small qtys to 11.1.1 . If you’re not affected by the ‘sudden drop in temp’ bug in your climate, I’d stay on iOS 11.1.1 . The other fix in 11.1.2 I could never find info about (videos distorted?).

      • ChrisLinke

        Also, iOS 11.1.2 introduces a new autocorrect bug (easy work around, but still…). Forgot to mention that if you don’t have an iPhone X, this shouldn’t even be a debate. Stay on iOS 11.1.1

      That’s up to you. I have heard this is a thing, I don’t know if it affects all devices though. If you’re worried, it’s fine to remain on 11.1.1, it should still be covered by any future tool.

  • burge

    “If you have a 32bit device your probably out of luck but downgrade to 11.1.2.

    More like if you have a 32 bit device on iOS 11 that’s a f-ing miracle.

    • Arjan Vlek

      Was about to post the same. But anyways, a 10.3.3 jb would also be very nice 🙂

  • igobythisname

    I’m jb on 10.0.2, I saved blobs for 10.3.3 with hopes of (at the time) to future update/restore/whatever once a jb was released supporting 10.3.3; I believe a jb is out for 10.3.3 but now have been told that I cannot update to 10.0.2 -to- 10.3.3 since only iOS 11 is being signed.

    Pretty damn disappointing!

    So when I see you guys talking about -Save blobs, esp if you’re already jailbroken- that disappointment rises again!

    • Joaquim Barbosa

      This was possible previously, when iOS 10.3.3 SEP was available. It now doesn’t work as only iOS 11 SEP is signed. The exception is A7 devices, like the iPhone 5s. If you have one of these devices, you can still futurerestore to 10.3.3. If not, keep saving your blobs as you *might* be able to use them to move to iOS 11 instead in future. Blobs are not always able to be used, as things are very complicated with unsigned restores. I advise people to always save them because, even though you might not be able to use them in the end, if you don’t have them, you definitely can’t do anything.

    how do i restore backup from ios 11.2, if i downgrade to 11.1.2? itunes forcefully update me to latest software. pls help.

    • burge

      You download the iOS 11.1.2 IPSW and use that to restore too. Read the article and use the links within the article to see how to go about doing this.

  • Joshfei

    What are the benefits or tweaks that are compelling to jailbreak the apple tv? I’m more familiar with the iPhone scene.

    • Joaquim Barbosa

      Currently none, but this is partly because there have never been enough users on a jail breakable firmware to make an ecosystem arise. Ideally, we could get Cydia Substrate working, and have tweaks, unsigned apps, etc, just as on iOS. Someone needs to take on the challenge though, and a larger audience makes it more likely. A jailbreak is the first step obviously, so stick on tvOS 11-11.1 if you can.

      • Joshfei

        makes sense, thanks for the response.

  • diggitydang

    No iPhone X .ipsw’s in the Download section? It only goes to iPhone 7 Plus… am I missing something?

    • diggitydang

      Nevermind… I found it… it just doesn’t go in order… not order my iPhone chronological version anyway…

  • nathan stout

    I restored and am successfully on 11.1.2 but now when im setting up my phone it give me a page titled “Software Update” and forces me to update before I can use my device

    • Hdagniel Hdavyo

      same for me

      • pjstran

        Any answer as to why this is and how to work around it?

    • Joaquim Barbosa

      Really? I’ve never heard of this before, do you have a picture? Which device are you on? Have you tried connecting to iTunes to activate instead, or setting up with no wifi so that it can’t check for updates? Did you use Restore or Update in iTunes to get to this point?

      • pjstran

        I tried both…shift+restore and shift+update and both brought me to a page called “Software Update.” The only thing I can think of is I didn’t put my device in DFU mode prior to the shift+updates using iTunes. Of course, used iTunes for this process. I am now locked out of the potential jailbreak because of this Software Update page…very odd.

  • speaking of downgrade, im at 11.1.1 and i have my shsh saved of 10.3.1 theres a way to downgrade with my blobs saved from that ios ??? ios 11 is too laggy for my 6s and honestly i dont like ios 11, theres a way to downgrade to my saved blobs ?? thanks 😉

    • Joaquim Barbosa

      I’m afraid not, sorry. Downgrading to iOS 10 from iOS 11 doesn’t work because you have to use the iOS 11 SEP, which isn’t compatible with iOS 10. The only devices which can move iOS 11 to iOS 10 are the A7 devices (iPhone 5s etc.), because they have iOS 10.3.3 SEP still signed by Apple, for some reason. I’d advise you to do a full manual restore (not update) of your device to iOS 11.1.2. A clean start might speed it up, and iOS 11.1.2 might have small improvements too. Then wait there for a possible jailbreak. Instructions for how to move to iOS 11.1.2 are in the article above. Thanks for reading!

      • But the thing is iOS 11 is too laggy 🙁 but if iOS 11.1.2 is still signed well I’ll download it 2nit and do a complete restore from 0 with out nothing installed

  • Emmanuel Moyana

    Thanks for the article

  • MESTIRI Ahmed

    If you’re on 11.2 or higher it’s important that you use the alt + update button instead of alt + restore or you’ll erase your iPhone and can’t restore your data back (iTunes will force you to update in order to restore the backup made on 11.2). https://uploads.disquscdn.com/images/5833d24a631e547f6433829b2af589c513aeb0adc6cd424c8be0d7e970fe786d.png

  • Joaquim Barbosa

    Correct! Don’t try to restore now 🙂

  • 王秀英

    Thank you for this article. It has got to be the most detailed which is out there at the moment. I have got an iPhone 7 on 11.2.1. I have the blob for each iOS version saved. How to downgrade to 11.1.2? I have been searching so much and found this article in the end. Please tell me the blobs are actually worth something! Thanks again, mate.

  • Kurdo Kamal

    hello guys, is there any way that I can put my iphone 7 with 10.2.1 to IOS 11.1.2? I have shsh for all other ios in the between. or should I upgrade it to 11.2 then downgrade it to 11.1.2? but I read that you can’t downgrade even with shsh anymore ? please I need some advise. Thank you.
