There’s a new release in the jailbreak line-up: an iOS 10.2.1 tool called Saïgon. Although it still doesn’t cater for the latest firmware versions, it comes closer than we’ve seen in a while and what’s more, is for 64-bit devices. We’ve waited a few days to see any early reports of success, before collecting up the currently available info on this most recent development in the jailbreaking world.

The Saïgon jailbreak incorporates three publicly released exploits into a single tool. It had been known for some time that the exploits known as ziVAtriple_fetch, and the kernel protection bypass (used in extra_recipe and Yalu) could be combined into a jailbreak for various iOS 10 firmwares, but until now no-one had seemed prepared to step up and perform the tricky work required to do so.

Developer Abraham Masri has taken up the task and managed to get the full jailbreak running on a small selection of devices, in a first beta posted to the Saïgon website.

Saïgon jailbreak compatibility

At present, the supported device/firmware list is a little ænemic, as seen below:

  • iPhone 6/Plus (10.2.1)
  • iPhone SE (10.2.1) (untested by developer but reported working by users)
  • iPhone 6s (10.2.1) (untested by developer but reported working by users)
  • iPad Air 2 Wifi (10.2.1) (untested)

However, there seems to be no reason why support should not extend eventually to all 64-bit devices on iOS 10.2.1. Further work, apparently based on devices’ video drivers, is needed to widen support.

Interestingly, triple_fetch works up to iOS 10.3.2, and ziVA works up to iOS 10.3.1. This means that some devices could eventually see a jailbreak up to iOS 10.3.1, though this remains to be seen. Other considerations to do with KPP and Cydia Substrate make this proposition a little more complicated, but the Saïgon website does claim that iOS 10.3.1 support for iPhone 6s is coming.

At the very least, the exploits should allow Saïgon to be used as a nonce-setter on firmwares up to iOS 10.3.1, even if it doesn’t end up being a full jailbreak above iOS 10.2.1. This would allow restoring to unsigned iOS 11 firmwares with futurerestore, if a jailbreak later becomes available for them. So you could save blobs for each iOS 11 firmware which is released, stay on a Saïgon compatible firmware for now, and make the jump at a later date.

Early reports suggest that the new tool is somewhat finicky, with some succeeding almost immediately whilst others struggle for hours before managing to jailbreak. It is to be hoped that this can be improved in later betas, though sometimes the exploits being used have a fundamental (in)stability which cannot be improved upon.

We’ll keep you updated on Saïgon’s progress, especially when more firmwares and devices are supported, but if you have a device on iOS 10.2.1 and would like to check it out now, the first beta can be obtained on the official website. For those wishing to peruse the code, try the author’s GitHub page. I personally am waiting to see if support arrives up to iOS 10.3.1, as the only devices I have which aren’t already jailbroken are on that firmware.

Have you successfully used Saïgon? Is your device due to be supported soon? Let me know your experiences with the tool below; it’d be interesting to get an idea of its stability.

    For once I thought this was an actual Jailbreak realease. IDB Please for goodness sake. Oh! This is a jailbreak.

  • Sampler

    Who else with iPhone 7 10.2 felt tremors in body after reading title?

    • prym

      yea, I need one for iPhone 7, thats why I still stick on 10.1.1 😀

  • pnh

    2015 called. They want their jailbreak back.

    • Abraham Masri

      🙁

  • Syjic_666

    Dam for some reason I decided to stick with iOS 10.2 – thought that would be useful but just missed the mark it seems. 🙁

    • David Gow

      Lol I think 10.2 is prior to 10.2.1 u should b ok

      • Syjic_666

        Hmm really oh OK I seem to have forgotten that one is able to upgrade to any firmware that is higher than the current one installed via other dowbloadble links. It’s been so long that I thought one can only upgrade to the latest firmware Apple has released. TX 🙂

      • pegger1

        You can only upgrade to the firmware that Apple is still signing for a particular device. Which is typically the latest firmware (sometimes the latest couple firmwares). To update to a firmware that isn’t the latest, but is still being signed by Apple, then you need to do it the manual way and download the firmware.

      This JB does NOT support iOS 10.2 ((((((
      (Let’s hope it will in after beta versions)

  • MMA Rules

    Zzzzzzz

  • It would seem that all hope is probably lost for those that upgrade to the 8/8+/X this year (at least for a substantial period of time if anything)

  • Jerry

    Another waste of time

  • M_Hawke

    7 Plus on 10.2.1 here, crossing all my fingers. Not motivated to upgrade to 11. Especially since there are many reports of problems. I did on my iPad Mini 2 and it really hasn’t changed my life. As a matter of fact, it has made it just a tiny bit more of a hassle. Not impressed with iOS 11.

  • raj joshi

    SUCCESSFULLY INSTALLED CYDIA ON MY IPHONE 6 iOS 10.2.1…THANKU VERY MUCH SIR…

  • WTF i updated my 6 plus last week

  • baddestsammaritan

    Its been a long wait for a 10.3 JB on iPhone 7+ Is it fair to say JB is dead in this day and age for 7+ devices?

  • mike ochoa

    Jailbreak Is dead. Let’s face it. Some devices never have seen a jailbreak

  • Deep Wadana

    Iphone 5S device

    • LOL That’s what you get when you use jio.

  • Hokese Oner

    Support for

  • d_buchino2677

    Jail broke my iOS 10.2.1 iPhone 6s last week. So happy I never updated and remembered to always stay on the lowest possible firmware possible like all the pros say to do.. after losing my. Yalu 10.2 jailbreak to a bootloop, I stuck it out and it paid off!!

  • Rayane Merabet

    Anyone ask for iPad mini 2 ? Processor are 64 bits to , maybe share with other device so it’s can be easy to transfer those exploit ..

  • Joseph Orlandi

    Has anyone successfully jailbroken an iPad Air 2 (Cellular+Wifi) running iOS 10.2.1? To specify the device has no data, no accounts signed in, and the iOS software was installed via iTunes, not OTA.

  • Henry Gleeson

    Mine keeps getting to privilege escalation on the jailbreak and then resetting. Anyone know what might be causing this?
