  • iOS 5 Beta 4 Over-The-Air Update Not Compatible On Jailbroken Devices


    DISCLAIMER: iOS 5 is in beta and should be treated as such. Choosing to update or use an iOS beta is at your own risk. Be wary, cautious, and fully aware of the issues, consequences, or actions that may come about as a result.

    Today, as ModMyi reported earlier today, Apple has released iOS 5 beta 4 for developer use via the iOS Developer Center. One of the key new features to this update is the over-the-air update capability; an addition that has been long awaited in the community. Although the over-the-air feature is something new and exciting to try, for jailbreak users, you're out of luck for the time being.

    A few minutes ago, MuscleNerd (@MuscleNerd) tweeted out that jailbroken devices cannot update to iOS 5 beta 4 using the over-the-air capability due to some new "surprises" from Apple. This statement may clear the air in regards to people who may be frustrated and curious why OTA is not working for them on their jailbroken device(s).



    According to his statement, the OTA update checks the folder /Applications on your device to check for certain components; possibly sniffing out the jailbreak folders and files - something that he calls:

    It is unknown whether any of the dev-teams (iPhone Dev and Chronic Dev) are working on a fix or a means of bypassing this issue. Stay tuned and be wary of what is to come. In order to update to iOS 5 beta 4 on your device right now, if you have a jailbroken device, use either of the following two ways:

    • Restore to non-jailbroken iOS 5 beta 3 and use OTA
    • Do the traditional IPSW file update directly from iTunes using iOS 5 beta 4 IPSW


    UPDATE: Venexon (@Vexenon) tweeted out that the redsn0w beta 2 software that jailbroke iOS 5 beta 3 does not work on iOS 5 beta 4. If you're looking to keep your jailbreak on iOS 5, do not update at this time.

      Why? It is a stunningly elegant solution that works - if it hasn't for you then please let people know what the problem is rather than just post that.

      JBM was pretty good,
      but for style, stealth and overall technical excellence,
      these guys had the best jailbreak ever:

      If, OTA updates works for jailbroken devices, as soon as the update was applied your precious jailbreak would be gone. Just as if you updated in itunes with a stock apple firmware.

      Muclenerd has said he would "disable" these updates just for this reason. Now apple has decided not to "enable" them for jailbroken devices, hence the "present from apple".

      OTA updates are not something jailbreakers should be desiring. Its the exact opposite in fact..

      It's not a full update. Full updates are basically restores without the settings and media reset. A regular update uses the [huge] ipsw and it replaces all system files and apps. The OTA updates only update files that have been updated. That keeps the update size much smaller than the usual 700+mb. So the hope is that they can bypass any checks and still get the updates. Only problem is that apple will start updating core files to intentionally break the jailbreak. Fingers crossed for something good...

      Apple could easily check whenever you sync. They could just "verify" the iPhone. All they'd have to do is have iTunes send a random unsigned code and attempt to execute it. If it executes successfully then the device is jailbroken (similar to the iBooks thing they tried). But remember how much attention that got? People were furious that their book store wouldn't download anything. If apple did that same check but disabled, wiped, or reset the entire device, people would be furious and apple would get much more negative attention than they'd like.

      Tyler is actually sorta right. I'd say the most unstable jailbreak was ziphone. Heres why:
      ZiPhones 1-Pass method stuffed everything into the ramdisk, this led to memory corruption, like grayed out Wi-Fi or bluetooth.

      ZiPhone automatically downgraded your bootloader to 3.9, which thankfully could be updated again using Bootneuter. The reason this was bad was that if your iPhone was 1.1.2 or higher, you were screwed permanently, thanks to the Dev team though Bootneuter was an amazing (but again, dangerous if not used properly) tool.

      That's enough about ziphone. It's the most unstable jailbreak though. Just sayin. Haha.



      ANYWAY back on topic here.
      Addressing the stability of JBM3.0, let's go to one of our experts, jay freeman aka Saurik.

      -Me: Jay, what do you think of JBM3.0's stability?

      -Jay: comex is in /such/ a hurry that his new jailbreak will have a poorly tested kernel driver in it. I'd wait [...] to use it.

      ( twitter.com/Saurik )

      Well that's what Saurik thinks. If you want to disagree with him then I call 'ignorance'.

      OTA updates don't work on any modified device. Its across the board with Android/iOS/BlackBerry. If you mess with your OS, the check fails and Apple won't update it. Simple.

      Yes. What I'm adding is that people are thinking of bypassing or disabling the check (like wtf) but even IF they trick the check, apple can just update core and system files to break the jailbreak.

      Partly agree on that. With the benefit of OTA, Cydia could start offering Unthethered jailbreak updates
      That indeed would be useful to most iDevice users; but no loss at all, it only takes approximately 20 minutes to achieve the same thing over a wire, so long as you have all you jailbroken apps/tweaks backed up with something like PkgBackup

      Problem is that Cydia or anyone can't fix the delta updates and then push jailbroken ones out to you because then it would contain Apple code, the part of the delta update, and that would shut them down fast. That is why with custom firmwares the dev teams provide you with a tool that adjusts the firmware and you are responsible for getting the firmware and using the tool. The tools they have contain no apple parts so they can avoid lawsuits. That is why we saw the iPad 2 jailbroken day 1 and took so long to see it. It was said that in order to jailbreak it he had to use some of Apple's code.

      Heh, totally forgot about the lawyers (aka liers) when I was posting
      Totally agree on that; especially with all these "shouldn't be there" software patents breaking the competitions

      Yep, have to make careful steps to play the game and not get in trouble. Much like large corporations do also.
