Cydia Installer Preparing Filesystem

Saurik has pushed an update to Cydia Installer, bringing it to version 1.1.25. This latest version of Cydia Installer moves jailbreak content found in /Applications to the user partition from the System partition. It’s recommended that all users update as soon as possible.

Update: Cydia Installer was updated to version 1.1.26 shortly after being updated to 1.1.25. The latest version doesn’t show any release notes, but we assume it is just a minor update to the more notable 1.1.25 version.

Here’s what Saurik had to say about the update:

When Pangu and I were discussing the jailbreak release for iOS 9, there was originally a limitation of the jailbreak (due to Apple’s mitigations in iOS 9 being “actually effective”) that made it impossible to free disk soace by moving /Applications from the system partition to the user partition. After doing a bunch of testing without moving this folder, we ran into a similar issue with another folder that Cydia was still stashing. After contemplating just not stashing almost anything, we made a painful “executive decision” to make a wider sandbox carve-out than normal and allow for these folders to be moved, but that Pangu would spend time attempting to fix this somehow. It was not clear to me in which direction they would “fix” the issue, and so I’ve been concerned about pushing an update that stashes /Applications. However, as of last night, Pangu has told me that they will not be pushing a change to break this feature. Also, Apple just released iOS 9.1, so I’m pushing this Cydia update now in order to minimize the number of people who run into some problem with a “late stash” after the signing window closes, which will happen very very soon. (Meanwhile, I’ve been spending most of my time for days working on updating the Eraser feature of Cydia Impactor to support iOS 9, as Pangu is now doing something more complex that I previously was not setup to “undo”, in addition to Apple making some changes to the OTA format. I managed to get this done just in time, though I also ended up managing to do it without having to actually restore my device a eve once.)

This means that jailbreak content will be moved from the System partition, and hence, Cydia will have to perform a “Preparing Filesystem” after installing this update. This explains why “Preparing Filesystem” was so fast on the new jailbreak, because this stashing wasn’t done upfront with the version of Cydia Installer bundled with the jailbreak. It actually had nothing to do with iPhone 6s performance, as I once speculated.

Cydia Installer System Partition

Check your storage via Cydia → Storage Information → Storage

As you can see from the screenshot above, installing Cydia Installer version 1.1.25 allowed me to reclaim some of my System partition storage space. I don’t have tons of jailbreak content installed on my device, so it wasn’t a huge deal for me, but for those of you using apps that take up lots of space, this will be a positive change for you. It also means that the “Preparing Filesystem” may take significantly longer for you, depending on all you have installed.

As Saurik stated, it was a wise move to deploy this update prior to the signing window closing for iOS 9.0.2. As you know, iOS 9.1 just dropped, and it effectively kills the current Pangu jailbreak. Users who ran into stashing errors may be forced to restore, which would render their device un-jailbreakable when the signing window closed. Saurik wanted to avoid any of these potential issues, hence the release of Cydia Installer 1.1.25.

Interestingly enough, Cydia Installer is actually showing as version 1.1.26 when you open the package page in Cydia. I’m not sure if this is a typo, a mix up, or what. We’ll be sure to provide you with an update when we are able to get to the bottom of this.

Have you updated to the latest version of Cydia Installer?

    Got the 1.1.25 upgrade opened cydia a few minutes after there was a 1.126 upgrade

  • Peter

    Just updated, then rebooted and now my phone is stuck in a bootloop. Ugh I guess I have to update to iOS 9.1 now and wait for the next jb which better be soon

    • Mhamad J. Hajj Chehade

      Upgrade then downgrade lol

      • Saulo Benigno

        True 🙂

    • Julio M.

      Same thing happened to me, stuck without a phone for the whole day :/

      • Arjun Vegda

        what is the solution ? can we save our photos ?

      • Julio M.

        I downloaded the 9.0.2 IPSW and restored my iPhone to that then jailbroke again. If the photos are backed up to iCloud they will be saved. If not, you’ll have the latest from the last time you backed up.

      • Arjun Vegda

        but itunes isn’t detecting my phone 🙁 and my phone is just showing the apple logo

      • Julio M.

        Oh. You have to put it into DFU mode. Hold both the power and home button until the screen goes black, let go of the power button but keep holding the home button for about 5 seconds.

        Do this connected to the computer so you know when to let go, as soon as iTunes recognizes it, you can let go. Then just restore.

    • Newgunnerr

      No dude the signing window is probably still open for 9.0.2 hurry and restore to 9.0.2 !!

    • Cristian B

      Me too dude. Had to restore. At least I’m still on 9.0.2. I’m the fence on wether I should jb again or wait for 9.1 jb

    • Shadowelite123

      same…. got stuck in a boot loop and now waiting on the ipsw to finish downloading… its actually because you update the pangu untether package and the cydia installer package at the same time. thats why you get sent into a boot loop

    • VITICO

      same thing just happened to me..

    • Jayy

      mine is doing the same thing, what do I do? i’m already in the process of downloading 9.0.2 to my laptop to re-jailbreak, which I dont feel like doing!

      • rimzan

        same issue here , can u give me download link of 9.02

    • Pritpal Singh


    • Jayy

      I just re-jailbroke

    • Ramo L

      Found this solution elsewhere and it works for me:
      “Here’s a solution I used to fix it unti a patch is released. While powering on your phone, hold on the up volume key to boot without subrate, if not allready installed, install icleaner pro and open it. Go to the + tab and go to subrate add on’s. Disable then all. Now reboot you device normally. It should avoid the boot loop of death. Now go back into icleaner and enable everything again. Now respring. Your tweaks should now work. Don’t reboot. Otherwise you will have to do it again. The only thing that does not work occasionally is winterboard. I’m on iPhone 4S 9.0.2 and this worked for me. Hope this helps someone.”
      I hope this helps.

    • Joostiphone

      Make a backup in iTunes. Dfu. Shift+restore to ipsw 9.0.2. Setup as a new iPhone. Jailbreak with latest pangu. Restore the backup.

  • William Melendez

    Reading your comment got me nervous. Not touching that upgrade quiet yet.

  • Adam W

    hey, after cydia update and shows Restart Springboard, cydia crash, take me to home screen. After a maual respring there is nothing in all of my sources, no packages, any fix???

    • RedSymphony

      Same with me but what I did was I didn’t respring I just open Cydia let it do its thing and then it auto resprings

  • Shadowelite123

    For those who didn’t know, don’t update cydia installer while also updating the pangs untether package at the same time. it will send you into a boot loop causing you to restore and update.

    • Adam W

      pangu said that in their untether page

    • socrates

      I updated both without a problem. I wonder what makes this effect some without effecting others.

    • David Ruiz

      If only I read this 10 minutes ago…
      Today I went to Corvette factory and lose all my photos ):

    • I updated both at the same time and was fine so it’s gotta be something else

  • rubeN

    whats the latest pangu untether package?

  • Saulo Benigno

    Why update? I read only problems about it.

    What will be the benefit?

    Everything is working fine for me on the old version. What about you?

  • wswalex

    man.. i really need a fix for the crashing photos app


    same here.. smh

  • rubeN

    Safari is crashing on my Air 2 everytime I open it.

    • rubeN

      Working fine now after a reinstall Cydia installer and a few reboots

  • monsytrons

    This post should be updated to tell people to stay far away from the update. I just updated and now my phone is stuck in boot loop. Can’t even get iTunes to recognize that the phone is plugged in so I can’t restore. Have tried booting into no substrate by holding the volume up button, hard reset, nothing works. Stuck at Apple logo.

  • George

    I had an issue where after i updated cydia i couldn’t open up my phone/contacts or safari i just reinstalled a random tweak rebooted and everything went back to normal.

  • Tim

    Yay infinite boot loop. Thnx. <3

  • Keyzer Soze

    1.1.25 killed the system, leaving a bootlooping device

  • Gregg

    Stuck in a boot loop… So annoying… And prior to this “upgrade”, it was working so great.

    • Arjun Vegda

      whats the fix now ?

      • Gregg

        As far as I understand, you have to restore to stock and re-jailbreak. I don’t feel like doing that right now, though. For now you can get out of the boot loop by holding the volume up button during boot up. I reinstalled the Cydia installer and rebooted a few times, but that did nothing. Really wish they would fix this.

      • Arjun Vegda

        that isnt working either ? how am i supposed to do ?
        i tried holding the volume up button and power button. but its still stuck on apple logo.

      • Gregg

        Not sure what to tell you. I can boot normally by holding the volume up button.

  • Nesly Lacroix

    My iPhone cannot access the internet after I jailbroke and updated Cydia Installer. Anybody having this problem? I have isolated the issue with the latest Cydia Installer. I jailbroke another device and had no problems before launching Cydia.

  • I did the upgrade and now my system partition has even LESS space.. I had 15% before and now I’ve only got 8%

  • Rizz

    My just keeps saying preparing file system been like that for at least an hour

  • Mike Chille

    Hey everybody, i’m having some problem with my JB.. What i mean is that i did everything like you told us and at the end i have my Cydia (but still have the Pangu and the WWDC on my screen) and when i open Cydia the app isn’t 100% complete.. I have made some print screen if someone wants or can help me that would be really great.+

    Should i just wait that Cydia Impactor get updated??
