Cydia Substrate

If you’re jailbroken on iOS 8.3, you’ve likely been frustrated by the lack of Cydia Substrate support up until now. As you’re no doubt aware of by now, Cydia Substrate hasn’t worked on iOS 8.3 due to a fix that needs to be implemented by the folks at TaiG.

The good news is that the fix is out, and I’ve confirmed that it works. If you’ve jailbroken your device with the TaiG 2.0 tool yesterday or earlier today, you can use a simple .deb file install to fix Cydia Substrate in just a few minutes.

In this tutorial, I’ll show you how to install the TaiG 8.3 Untether .deb on your jailbroken iOS 8.3 device and fix Cydia Substrate.

Note: TaiG has warned users not to use this release, as it is still in testing. Proceed at your own risk.

Note: Your device must already be jailbroken with the TaiG 2.0 tool.

Step 1: Install iFile from Cydia

Step 2: Force close Cydia

Step 3: On your iOS 8.3 device, go to our download page

Step 4: Tap the TaiG 8.3 Untether.deb download

Step 5: Tap open in iFile

Step 6: Tap Install

Step 7: Reboot your device after the install completes

That’s all there is to it. Now go enjoy all of the compatible jailbreak apps and tweaks that rely on Cydia Substrate! We’ll be back with a full tutorial for the TaiG 2.1 jailbreak tool for Windows a bit later.

    After I reboot my phone, it automatically reboots itself nonstop.

  • Joe

    Why is this happening!!? How do I fix this problem!? This error comes up on almost every app I try to download!!!

  • Wesley Elder

    Hey, i have installed this, everything seems fine, but i can’t install any of the tweaks i want, barrel for example. In cydia it says “This product is not supported on your IOS version” Are people installing these manually?

  • whendovescy

    Happy camper, followed the the tutorial video and I have a working jailbreak! Thanks 🙂

  • Rujo

    I did all this, and rebooted my device. It still says “recheck” where it should say “install” in every tweek I`m trying to download. Does that mean that the TaiG 8.3 Untether.deb download didnt work?

    • Joe

      Has anyone figured out this problem yet??

  • Amin Yasin

    Anyone who has trouble with Tweaks not showing up in the setting tab, i found a method to clean install Preference loader.

    1. Open Cydia.
    2. go to installed tab
    3. Switch to Expert tab at the top.
    4. Remove Preference loader and Respring the device as Prompted.
    5. After Respring, you have the reboot the device again. Power off and Power ON again.
    6. Install Preference loader from Big Boss and respring.
    7. Install any tweak and you will find the tweak in the settings.

  • Roly

    very noob like of me, i know that (last i recall) cydia has to be updated or something of the like, in regards to being unable to download theme packs in Cydia. Keeps saying my version of iOS is unsupported. I want to support the devs with a legit purchase, any work arounds to this so that I could swap my icons out on Winterboard?

  • Alex

    Guys… I’ve already installed cydia, but when I download a tweak it doesn’t appear me on settings

    Does the 2.1.x version of TaiG includes the Cydia Substrate fix or we still need to do it manually?

  • Martin Mohlala

    I have updated to IOS 8.4, however Cydia is not working. Error: cannot locate package.

  • frank

    can someone help me, cydia sources there no update

  • Anon

    Does this work when you have jailbroken the device with pp?

  • Burton S

    No. I mean that it shouldnt be described as a 30 stage process to move information from the device to the SD card, and however perhaps not function 75% of the time. Im not just a telephone designer, i dont need that full mess of a UI, actually if it lets me cistomize my icons or whatever. I couldnt care less. I want my telephone to function correctly without 6 hours of tinkering.
