Winocm shows off untethered iOS 7.1 jailbreak on iPhone 4

By , Mar 20, 2014

ios 7-1-untethered

Well known hacker and future Apple employee winocm posted a video demonstrating an untethered jailbreak of iOS 7.1 earlier today. The video, which he posted to YouTube, shows off what appears to be an untethered jailbreak on a Verizon iPhone 4.

In a brief tweet, winocm sent out a link to the video with the caption ‘iOS 7.1 untethered boot.’ Now, details regarding the clip are very scarce right now, but the fact it exists is fueling hope for folks on newer firmware wanting to jailbreak their devices…

Again, we know nothing about how winocm was able to pull this jailbreak off or if he has any plans to release his work to the public. Remember, he began showing off an untethered jailbreak for iOS 6.1.3/4 last summer and it didn’t appear until late December.

The video is noteworthy though, as Apple killed evasi0n7 when it released iOS 7.1 earlier this month, leaving users without a way to jailbreak. Also noteworthy is the fact that fellow hacker iH8sn0w says he’s going to record a similar video with an A5 device.

Thanks to everyone who sent this in!

    OMG OMG TEAM JAILBREAK ALL THE WAY

    • Jerry

      really? LOL

  • CAS

    I think he post it as a demostration that it can be done, I don’t think he will work on it when he is about to work for apple.

  • Chun-Li aka ThunderThighs

    “iPhone 4″ Won’t be shock or amazed until he actually does a A6+ Device Jailbreak. Else wise this is pointless. Especially since Semi Restore and iLex made the scene from preventing any updates.

    • RarestName

      Because new devices are always jailbreakable, right? Right?

      • XboxOne

        because most people care about the newer iDevices. Bet you use an iPhone 4, iPod Touch 4th gen and iPad 2 lol.

      • RarestName

        iPhone 5s, iPad 4, Nexus 7 (2014) and Moto G.

      • duck hairs

        Nexus 7 2014 ay?

      • RarestName

        Oops, 2013.

    • Palmer Paul

      SemiRestore and iLex both have limitations.

  • Marcus

    I doubt this will be released. He is going to be interning at Apple soon and why would he waste precious exploits on a 7.1 jailbreak anyways?

    • Matt

      Such exploits
      Much worth
      Wow 7.1 jailbreak

      • Marcus

        It’s 5 A.M. I’m doing homework and you made me laugh. <3 Doge

    • Jonathan

      It’s not exploits… it’s a bootrom exploit. They’ve been using the same exploit for the iPhone 4 for a tethered jailbreak. There is no loss here.

      • Marcus

        A bootrom exploit is still an exploit. It literally says that right in the phrase. “Bootrom EXPLOIT.” This is also an untethered jailbreak so it’s not even using the LimeRain bootrom exploit. It’s using another exploit and that shouldn’t be wasted on a 7.1 jailbreak.

      • Jonathan

        If that’s the case, those who update to 7.1 on an iPhone 4 will never see a jailbreak again. I am 99.9999999999999% sure that the iPhone 4 will not see iOS 8.

      • https://pbs.twimg.com/profile_images/412035973686366208/r14EeLu9.jpeg CPVideoMaker101

        i already am jailbroken on iOS 7.1 on the iPhone 4

      • Damian

        How?

      • Arjan Vlek

        iPhone 4. ‘Nuff said.

        (Tethered is always possible on ip4)

      • https://pbs.twimg.com/profile_images/412035973686366208/r14EeLu9.jpeg CPVideoMaker101

        iPhone 4 will forever have a tether jailbreak.

      • James

        what site or link did you use for this?

      • Marcus

        I think you misread what I said. When I said they wouldn’t waste an exploit on a 7.1 jailbreak I meant that they wouldn’t waste it on an untethered jailbreak. A tethered jailbreak already exists for the iPhone 4 on 7.1 because of the LimeRain exploit.

      • Jonathan

        Ah. I need misread it. :P I assume they’ll do what they dif for 6.1.x. Wait until iOS 8 is out when Apple stops updating iOS 7, and make the jailbreak then.

  • Luuc

    Capacity: 4GB? LOL

    • Carlos Gomes

      What’s so funny about it?

      • Ian

        The capacity. That’s what’s funny.

    • ThatsMe

      It happens when sectors and parts of the NAND, become unwriteable. Phone interprets those as not present. It happens to people who mess around with and their phones internals alot, and those who use the device to the end of the NANDS life cycle (~256k read/writes average for slightly older NAND Devices)

    • http://173.58.214.169/ Anthony3595

      Actual formatted capacity less!! Also with the space that iOS 7 takes.

  • kokeropie

    Doesn’t iPhone 4 will always can be jailbroken for tether due to limerain exploit?

    • Nirvana

      Yes, l1mera1n does bring the tethered jailbreak, yet this is only an untethered boot, no Cydia

  • Nirvana

    winocm should release the jailbreak before going to Apple. He may put more work onto this! (with the help from ih8sn0w as he once did with 6.1.3 jailbreak maybe)

    • Ernie Marin

      and pretty much ruin his opportunity at Apple by doing the same thing they hired him to stop doing, i don’t think so.

      • Sandy Cook

        lol. Somehow I highly doubt he was hired as a means to stop him jailbreaking

      • Nirvana

        Don’t know, Apple may address him with the bug on the next update (like evad3rs were) instead of firing him or hiring him to cease jailbreaking!

  • suttonmontreal

    If he releases it. He will get fired from Apple before he even starts working

    • Marcus Gomita

      I don’t think so. By doing this he’s making Apple safer by showing hacks in the iOS.

    • Umut Bilgiç

      I dont get why people think that Apple and JB community are like rivals. I get were the idea is coming from, but really, Apple makes software and some talented magicians find vulnerabilities to exploit. Just that.

  • Sean Keenan

    Would love to see a 7.1 jailbreak. Still on 7.04 and didn’t even bother with .06. Not updating untill a jailbreak comes, no matter how long.

    • Mademan

      iOS 6 is better than the gay colored ios7 for jail breaking, more compatible tweaks that working.

  • Matt

    Yuh uhm there was a post saying that iPhone 4 will always be jail-breakable
    Right??
    Well anyway pretty cool — now how bout one for the 5s

  • Reporte Apple 
  • Johannes Mertens

    Pretty sure he’s using limerain bootrom exploit, which only exists on A4 Devices.

    • Sandy Cook

      It’s untethered though

    • Marcus

      That’s only for a tethered jailbreak -.-

  • iltas

    can i jailbreak 7.1 in iphone 5

    • ConduciveMammal

      No

  • onebyone_

    respect! to both hackers for all your hard work and all of the time dedicated to this.

    Thank you!

  • abdullah575

    NONONO apple reslase iOS 7.1.1 to pacth the ios 7.1 untherd jailbreak !!

  • Kenrick Fernandes

    i’m screwed,can someone help me? I had recently upgraded to 7.06 and then after which i installed a few tweaks(i pay for all of them). Worked well for a month. But now my phone has become insanely slow. I have to keep restarting for it to become fast again but then after a couple of hours it becomes slow. Also i tried reinstalling every tweak manually, but doesn’t help. :( Can i re jailbreak somehow?

    • Dontwannaknow

      Try semi restore. Heard it works but never try myself.

    • f96lrs

      ilex rat it works very well i have used it icleaner also very good

      • Kenrick Fernandes

        you sir are a genius. just using icleaner worked :D

  • Ernie Marin

    you know since he’s going to work for Apple, chances are this exploit is going to be long gone before any public release can be made.

  • jp2002

    Jailbreak devs always have a root exploit not used in public jailbreak tools. He probably could have used it to demonstrate.

  • Abdl

    iOS 7.1 not worth it. So much problem it has!

  • Sandy Cook

    If anyone wants to TETHER jailbreak 7.1 on their 4 right now, check out Geeksn0w

  • irshad k

    Did anyone try jailbreaking using GeekSn0w jailbreak for iPhone 4 iOS 7.1 ?

    • Khalid Tahhan

      I tried geeksnow 2.6 3 times. I dont recommend it. I then restored 7.1 and tried ios soft dev v5 that worked well. Geeksnow trys to automate all the three steps into one which failed at different steps for me 3 times. So i suggest using ios soft dev v5 and doing the three steps seperatly. It is easy and there is a video on you tube detailing it.

      • irshad k

        Does that jailbreak gave you cydia ????

      • Khalid Tahhan

        Att is the gsm iphone 4 (firmware versions labelled 3,1)

      • irshad k

        Can you please say the disadvantage of this jailbreak ? Is all tweaks available of ios 7.1 ?

      • Khalid Tahhan

        Not all but u can try any tweak and see. You can always rejailbreak forever so no need to worry about loosing your jailbreak here. Just try. Most tweaks seem to work but on the ip4 i am minimizing the number of tweaks on it to not get slow down again on the system. Just install essential tweaks to you.

    • Sandy Cook

      Yes, working fine _so far_

  • ɑղժɾҽա

    I’m already jailbroken on iOS 7.1 (beta 3).

  • Lurker22

    Forget 7.1, i want an ability to go back to iOS 6. On my 4s upgrading to iOS 7 was the worst thing I ever did, so much slower than before.

    • mav3rick

      I hear you! 4S here will stay FOREVER on the real iOS, 6.

  • f1ght3r

    “Hey guys, look at what I can do!” – This doesn’t mean anything unless a jailbreak comes out of it. I’m kind of getting tired of some of these hackers teasing with these images of them jailbreaking their devices and then nothing comes out of it. Don’t get me wrong, I know there’s a lot of talent out there, but a lot of these guys just like to toot their own horns.

    • Sandy Cook

      Something’s always come from it though. They post stuff like this so people don’t lose hope every time something’s patched

  • nonchalont

    That’s great. Does 7.1 drastically improve the performance on the iphone 4? Because 7.0 on iphone 4 sucks. Makes my iphone 4 useless. My 3GS is faster on 6.X compared to i4. If 7.1 makes i4 buttery smooth again, then I praise 7.1 untethered!

    • Khalid Tahhan

      Yes drastically smoother on 7.1

      • nonchalont

        Good to know, thanks my friend. Can’t wait for untether JB for 7.1 for i4.

      • Khalid Tahhan

        Anytime bud.

    • Sandy Cook

      It’s not really any smoother that I’ve noticed, although I DO have reduce motion on

      • nonchalont

        Oh ok, me too. Just thought maybe less lag and quicker/smoother animation overall.

  • Leviscus Tempris

    My life sucks again. Shortly after March 12 My iPhone 5 began acting strange all by itself and began to delete my apps and data and replace them with “Other” Looking it up suggest my phone is now corrupt. Its 4 months past warranty and too late to jailbreak it again. I cant open any apps without them crashing out and I’ve removed 10 GB of data and instead of cleaning it its now 5 GB over full. Looks like I’m going to be jailbreak-less in a few days if I can’t find a fix without a restore.

    • sadaN

      Try deleting these files, the Springboard should rebuild you apps db:

      /var/mobile/Library/Caches/com.apple.LaunchServices-045.csstore
      /var/mobile/Library/Caches/com.apple.mobile.installation.plist

      good luck

      • Leviscus Tempris

        I will! the only thing that worked was removing music which only freed the space I wasn’t using. It stopped when I disabled iCloud services and synced manually but the rest of the space didn’t return, its just gone. iFile also cant find any files that are filling it up.

      • Leviscus Tempris

        Sadly those files arent on my phone anymore

      • Leviscus Tempris

        Ended up doing a semirestore, setting it up now. Going to try iCloud restore first and see if that helps. My entire backup was 350 MB for my 32 GB phone. I think it was Flex that caused it. All my data loss stopped when I uninstalled it and a tweak from it called “IdiotProof” may have been storing my locationd info on my wifi connection.

      • Leviscus Tempris

        Didnt work, I dont have those files on my iOS 7

      • Leviscus Tempris

        Issue stemmed from use of a tweak in Flex. My comment about it earlier was removed for some reason. I’m not attacking anyone, but when I say that I could watch my phone storage fill I wasn’t kidding. It stopped once I removed Flex and the add-on “Idiot Proof”. It seems that it was storing my locationd data every second. But how do I find the location of storage?

    • Damian

      SemiRestore, semirestore!!!

      • Leviscus Tempris

        All that did was delete all of my content and settings, plus half my phone is now other data…

      • Leviscus Tempris

        Turns out the issue was iCaughtYou Pro. It has over 8 GB of data in its .app folder and I’m still copying the data off my phone. Im using iExplorer to export my files from root and windows to search for issues now.

  • https://www.youtube.com/user/zetor4711 Douggie

    Will this work on a 5S with 7.1?

    • Tony Trenkle Jr.

      Read the article idiot…It only works on the Iphone 4 and its not even released to the public yet…

      • https://www.youtube.com/user/zetor4711 Douggie

        Tony, Thanks for the feedback. By the way having Jr. in your title is useful, it helps to distinguish your position if the gene poll of jerks.

      • Tony Trenkle Jr.

        *pool Guess I’m in the gene pool that can spell. :)

      • Agru

        You’re still a moron

      • https://www.youtube.com/user/zetor4711 Douggie

        Your witty repartee is only surpassed by your rudeness!

  • Brian Voll

    I think we can all wait for iOS 8

    • Khalid Tahhan

      Theoretically yes. I will do so on my iphone 5. On my iphone 4 i wont be able to load ios 8. Ip4 in my view is a better quality phone than the ip5. I intend to go back to it as my daily phone once a untethered jailbreak is released for the final iteration of ios 7. Thanks to ios 7.1 and how it returns the ip4 smoothness to the operating system now i can see myself reverting back to it. Better battery life, better built. I can live without lte really and siriport will get me siri on it. Unless ios 8 and ip6 are wow then i may upgrade again.

  • iltas

    CAN I JAILBREAK 7.1 IN IP5

    • Khalid Tahhan

      In your dreams yes, in reality sadly not yet.

  • Ethan Desmond

    why cant they always make the verbose boot everytime you turn it on?

  • Mark Babatunde

    Great work, Winocm! I hope to start working on jailbreaks soon! Can anyone tell me how to install Mac OS X Mavericks using VMWare Player?

  • Michael Hulet

    Personally, I say it’s fake. Remember DreamJailbreak? MuscleNerd called that guy out because of the verbose boot he did on an A6 that wasn’t plugged into everything. A verbose boot requires a *really* low-level exploit, such as a BootROM exploit or iBoot exploit. While I do realize that the iPhone 4 is susceptible to the Limera1n exploit, that requires (just like any other BootROM/iBoot exploit) it be in DFU mode connected to a computer, which this is not. Winocm an iH8sn0w are both very reputable, but I think they’re just joking with us

  • Siddharth Desai

    No need to re-jailbreak after using Semi-Restore.

  • HamptonWalley

    I hope jailbreak won’t come for 7.1 and my phones with 7.06 will worth more money.

  • Kenrick Fernandes

    semi restore is only for ios 5 – 6 and not for 7. On a brighter note i used icleaner and it worked..

  • Joao Carneiro

    How can i unlock my iphone 4 ? i have iOS 7.1 . I know i can unlock BY my carrier but its very expensive. Can someone help me ( i only see scams in the web, i want a legit Stuff :) )

  • yolo

    if he jailbroke it, then where is cydia?

    • Michael Hulet

      A jailbreak doesn’t necessarily install Cydia. All you’re doing when you jailbreak is allowing root access on your device and allowing the running of self-signed/unsigned code. It doesn’t have to install any kind of other software

  • Justin Clark

    I NEED IT FOR MY IPHONE 5S

  • hartefbrown1

    Why would he do that? It only upsets those on ios 7.1. I had to update because for the life of me i could not get my 23 gig back on my iphone 4s, and i tried everythin, i mean everthing, yes everything! So now i am stuck on ios 7.1

  • feng

    Hai Mr.iHsnow can you gave me ios7.1 jaibroken tool?

  • Harman

    Link not worth to be used :/ Some other link please.. a survey free link :(

  • christine Grimes

    where do i find the download for the iphone 4 7.1ios???? phone is stuck in a bootloop,
