iOS 8.4 Prepare Jailbreak

iOS 8.4 is scheduled to drop on Tuesday morning to usher in the Apple Music era. While this is extremely exciting for most iOS users, it should raise some eyebrows if you enjoy jailbreaking.

Although there have been rumblings and whispers about the fact that iOS 8.4 is susceptible to the same exploits that allowed TaiG to jailbreak iOS 8.3, until there is solid evidence, that’s all still speculation.

It’s possible that the release of iOS 8.4 could spell an early end to the fun we’ve been enjoying lately. So how does one prepare for iOS 8.4?

Unless Apple knew about the exploits used in the TaiG tool in advance of its release, then I think it’s unlikely that they issue a fix within a week’s time for iOS 8.4’s release.

As someone who’s worked in development for a large corporation, I know all too well about the code freezes that occur around big events like public software releases. If a code freeze has been in place at Apple for the last week, and it didn’t know about the exploits used until now, then it’s very possible that iOS 8.4 can still be jailbroken.

That said, you can’t guarantee something like a jailbreak due to its inherent complexity. There’s a lot of moving parts in play here.

What you can do, however, is prepare.

First and foremost, if you wish to jailbreak, you should make sure that you’re on the latest iOS 8.3 firmware, and that your device is in a state that you’re satisfied with.

You don’t necessarily need to run the TaiG tool on your phone yet, but you should be on iOS 8.3 to enjoy the latest firmware and all the latest fixes that Apple has introduced since iOS 8’s debut.

After iOS 8.4 is released, Apple will eventually close the iOS 8.3 signing window. When the signing window is closed, users will no longer be able to restore to iOS 8.3, and will be forced to iOS 8.4 if they ever need to restore for some reason. If it turns out that iOS 8.4 isn’t jailbreakable, then you’ll be stuck without a jailbreak.

Here are some tips to consider:

  • Make sure you’re on iOS 8.3, even if you don’t want to jailbreak right this second.
  • Perform a fresh restore on your device with iOS 8.3. That way it’s free of any issues, and will last for a long time should iOS 8.4 not be jailbreakable.
  • Save your SHSH blobs for iOS 8.3 just in case you are ever able to use them to downgrade in the future.

Are there any additional tips that you’d like to add? Sound off in the comments down below.

    Jeff, you have a typo in paragraph 3 2nd line. You say, “IOS 4 and it should read, “IOS 8.4”.

    • LOL. I think iOS 4 is past its time. Thanks!

      • Mac Shaughnessy

        Yup, no problem LOL.

  • Ali

    I plan to (soon) update to iOS 8.3 (not jailbreak yet) and see if iOS 8.4 is jailbrekable or not.

  • leart

    yeah i would love to be again on ios 4 😀

  • Chris

    Honestly, no, without Springtomize and other tweaks not working in 8.3 I’ll end up hating myself if I update. For the time being in staying with 8.1.1.

    • Adrian

      Stop failing. Just use the individual tweaks that make up springtomize… 8.1.1 sucks hard.

      • Damian

        There is no individual working tweak that could resize the icons

      • Jaime Micha

        I used Upscale and also tried Bigify both seem to work. I liked upscale much better but it changes the resolution of the whole OS, for example, I have an iPhone 6 using Upscale to have the resolution of an iPhone 6+

  • Matheus Lisboa

    I will probably update only my ipad to 8.4 (since there aren’t any really nice tweaks for iPad) and use apple music in it

  • Blip dude

    I’m just gonna keep my iPad Air 2 on iOS 8.1 for now, iOS 8.3 really does nothing for the iPad except a lot of bug fixes. My iPhone 6 Plus is on iOS 8.3 and all I’m seeing is an extra 2 icons (Apple Watch and Activity) and I have no use for those. If an iOS 8.4 Jailbreak is released, then I’ll update both devices accordingly.

    BTW, I’m not sure why no one thinks ahead, but if iOS 8.4 is still Jailbreakable with the same exploits, everyone may want to jump ASAP on Jailbreak because I feel Apple will have a better opportunity to patch it quicker.

    • Shadowelite123

      Uhh considering those are iPhone apps only, I don’t see much can of a problem really. Plus isn’t 8.1 still buggy?

      • Blip dude

        Not on my iPad Air 2, I’ve had no problems at all with this version of iOS 8 at all. Every OS is buggy, but I’ll admit iOS 8.3 seems a bit more efficient than the most. I’m noticing a lot of the issues that I had on my iPhone 6 Plus suddenly disappearing.

    • M2

      A lot of bug fixes isn’t really nothing.

      • Blip dude

        I would agree if my iPad Air 2 was giving me problems, but it isn’t. The iPhone 6 Plus however, did give me issues especially when using Safari and other apps on Landscape mode. Now with the 6+ on iOS 8.3 I feel it even more efficient and smooth even with a Jailbreak.

  • White Michael Jackson

    Does anyone know a collection of jailbreak tweak for an elderly person to make iphone easier to use? Just jailbreak tweaks please.

    • kurt

      Is it not already easy enough? Do you mean like make things bigger and what not?

    • Varun Soi

      There are plenty of awesome tweaks reviews in idownloadblog, go have a look! 🙂

    • Lucus Bendzsa

      Springtomize

    • Mr_Coldharbour

      Activator, this tweak breaks the boundaries with everything especially when it comes to accessibility. And Bigify maybe.

  • Lakh Jhajj

    Jeff, the only thing comes to mind is that if TaiG knew and has exploits that could jailbreak 8.4 then why did they rush to release a jailbreak for 8.3?

    What was the rush? May be u can explain better what was TaiG Team thinking. !

    As we Know people will update to 8.4 just to get Apple Music and it would made more sense to release a IOS 8.4 jailbreak instead for 8.3(if they had exploits to JB 8.3)

    • kurt

      More than likely because another jailbreak team had a jailbreak as well, maybe pangu jailbreak and its all about being first in that business. You have to beat your competition.

    • Arzensan

      I guess they just wanted to play it safe and make sure the community gets a jailbreak before iOS 8.4 rolls out cause Apple might

    • Svs

      M O N E Y

    • n0m0n

      I was wondering the same thing. My thought was maybe they pushed it out before the release of 8.4 just in case the jb didn’t work on it?

  • Jailbrkr21

    If someone (myself) is already jailbroken on 8.1 is it worth updating to 8.3 now? What extra stuff was added between 8.1 to 8.3?. the only reason i can think is that some apps might require 8.3 to install?? Thanks.

    • Shadowelite123

      Well since I updated, things have run a lot smoother. And for me, my jailbreak is running smoother as well.

      • Jailbrkr21

        So is it worth all the effort of updating and then rejailbreaking, adding all sources and reinstalling all tweaks?

      • kron1k 

        Id say so. I was on 8.1 and would get resprings every so often out of the blue. Now things seem very stable and smooth. Plus if you decide to get an Apple Watch you have the ability to use it.

      • Jailbrkr21

        I use my watch on my 6 plus that I don’t jailbreak, I was thinking for my iphone 5s that I do jailbreak but I think I will update tonight when I’m home.

      • kron1k 

        I use my 6+ with my watch…it’s even better being jailbroke. I’m likely going to upgrade my backup iPhone 5 to 8.3 later today so I can have a backup that I can use my watch with.

      • Jailbrkr21

        The only reason that I don’t jailbreak my 6+ is because sky go and banking also don’t work on jailbroken devices and I like the bigger screen for sky go. I always have a 5s with me anyway so I can jailbreak that one.

      • Damian

        Yes it is worth
        There is not much different but iOS feels faster and is defiantly less buggy

      • Jailbrkr21

        started the process. updated to iOS 8.3 but now need to jailbreak. wish me luck, this is the bit that normally fucks me over.

      • Shadowelite123

        In my opinion, yes.

  • Peter Fernandes

    Simple just stay on 8.3 til u know if its safe or not to upgrade 🙂

  • Mr_Coldharbour

    I’m looking to update to iOS 8.3 by tomorrow on my iPhone 6 before signing window closes and then jailbreak. Why I’m not waiting for 8.4? Simple, I’m not a fan of the new music app from 8.4, I’m NOT going to use Apple Music, I have all my music that I enjoy and love so I couldn’t care less about this Apple Music. Bombard me with hate comments of you must but I said my piece.

    • kron1k 

      Same here brother. I’m also not a fan of paying $10 a month for it either. To me Pandora and the music that I have are what I listen to. I don’t see that changing.

      • Mr_Coldharbour

        You know, I don’t even stream music, I want my music on my device (which is why I always opt for a +64GB iPhone) everywhere I go without worrying whether or not I have a decent cellular connection or an Internet connection at all. Plus I travel a lot and not everywhere do I get internet connection either that or it’s wonky. I have all my music either through past purchases on iTunes or the good-old CD rips on my iTunes library, and other methods of obtaining music. I just don’t buy into the whole music streaming gig, just as much as I didn’t buy into that Facebook monstrosity, I still don’t and never will. Also, the kind of music I listen to just isn’t available on mainstream music streaming services, they just put hit radio trash, I listen to underground music, 1/3 of which were never released.

  • Platy

    I’ve heard the jailbreak doesn’t work on 8.4 due to the DDI race condition being fixed (which has been used in jailbreaks as early as iOS 6).

  • Jailbrkr21

    Why will my jailbroken 5s not find the update for 8.3? Its on 8.1 now, wasnt there a feature in the JB that stopped the ota download files to save space on device and stop the annoying red update stamp on the springboard? Is there a way around this problem that doesn’t involve plugging into computer? I would like to download the ipsw on the device and update from there too. Thanks.

    • Mr_Coldharbour

      There’s no way around it. You have to plug it in to iTunes and restore to 8.3 from there. First of all, OTA updates make jailbreaks fail and are therefore problematic. Secondly, ever since iOS 7 jailbreaks, they disable the ability to update OTA because people might accidentally update and also the reason I just mentioned earlier on them making the jailbreaks fail and cause issues.

  • ilikeiphone

    8.3–>9.0

  • Hot12345

    SHSH blobs doesnt work with umberrela…

  • Chris

    If you look on apples point of view it would be profitable not to fix the exploits for iOS 8.4 when iOS 8.3 is still jailbreakable because it prevents many potential Apple music customers to update and usa Apple music. But since people don’t have to pay anything this argument is flawed 🙁

  • M2

    I’m sure someone will be able to port Apple music into 8.3 with a tweak. Also, maybe I’m missing something but who really cares about Apple music. Not sure what is so special about it. Apple radio seems sufficient to me.

    • Thomas Meredith

      Is Apple Music replacing Apple Radio?

  • Jordi Miró Miró

    Well I spend 24/7 listening to music, so I think I’m gonna send packing the iOS 8.3 Jailbreak if there’s none for the 8.4. I’d rather have Apple Music.

    • Austin

      Jailbreak. get spotify version 2.4 get spotift4all

      free spotify premium + Jailbeak…

  • Okada San

    I posted this on a different thread but didn’t get any replies so I thought I’d try here.

    Off topic here but I figured this is the best place to get some insight. I’m holding off on the JB for now but I just updated from 8.1.2 to 8.3. Of course I lost my previous JB but that’s ok since I plan on doing it after all of this gets fixed. Anyhow, I had untethered hey Siri installed when I was jail broken. Today, out of force of habit, I said “hey Siri” and it actually worked. I wasn’t plugged in to anything. Thought it was a fluke but it happens every time I invoke Siri (and it’s pretty sweet that it does!). I didn’t think this was going to be a feature until iOS 9. Any thoughts?

    • Konix

      Settings > General > Siri > Allow “Hey Siri”

      • Okada San

        Thanks for the reply but I wasn’t asking how to enable “hey Siri”. I was asking why “hey Siri” works on my phone even though the phone isn’t plugged in and I’m not jail broken anymore.

  • rfow

    With the amount of money I spend on music in the iTunes store, Apple Music is a must for me. I’ll be updating and hoping for an 8.4 JB. Literally the only reason I JB is for BytaFont and TetherMe (which I could do with out for the most part.)

  • ShawnTXDFW

    I’m unsure of what to do at the moment. I re-jailbroke my iPad. Went from 8.1.2 to 8.3 installed the TaiG tool and everything is good on the iPad. Reinstalled mostly all of the tweaks I had to begin with. But on my iPhone 6+ I’m on iOS9 beta 2. In a way I want to to jailbreak my iPhone, but only because I have an apple watch. That being said who knows what the future holds as far as jailbreaking goes when it comes to the watch. In a way, I like iOS9. In a way, I want my tweaks. So I’m split. What would you do? Would you jailbreak your iPhone if you have an apple watch? Any pointers here would be appreciated.

    • ShawnTXDFW

      Only downfall I forgot to mention was I already installed the beta 2 on my watch as well. So that might not help me in my case anyway.
