How to Install Houdini Semi-Jailbreak on iOS 10 – 10.3.2 for iPhone

There is a new jailbreak on the block, kind of, and it’s called Houdini developed by Abraham Masri or known as @cheesecakeufo on Twitter. Some of you may recognize this name because it’s the same guy that released the most recent jailbreak for iOS 10.2.1 dubbed Saïgon.

Before we begin any further, there is a quick disclaimer for the audience who are interested in Houdini. Following the developer, I think we should clarify that this is not an actual jailbreak. Rather, it’s more of customization tools that allow you to implement some jailbreak functionalities to your non-jailbroken iPhone.

I’ll talk more about what it does later on.

How similar is Houdini to a real Jailbreak?

It’s far from being an actual jailbreak because, for one, there is no Cydia. You will not be able to access the BigBoss repository to install jailbreak tweaks or third-party apps. However, you can still add Cydia sources and install themes onto your iOS device.

Like I mentioned earlier, think of Houdini as a customization app since it’s centered around tweaking the look and feel of your iPhone or iPad.

Here’s the list of features that you can expect to see.

  • Change the app’s icon of apps you installed from the App Store
  • Hide or rename your applications’ labels
  • Add Cydia sources and install themes
  • Clean all apps cache (similar to Ryan Petrich’s CacheClearer tweak)
  • Change your device display solution
  • Customize your passcode keypad
  • Add different colors or resize icon badges
  • Theme your Control Center icons and sliders
  • Customize the Music Control icons from your lockscreen

According to the developer’s release note on Reddit, there could be more features to come.

How to Download & Install Houdini on iOS 10 – 10.3.2

  1. Click here to download the Houdini.ipa file.
  2. You will also need to get Cydia Impactor on your computer as well. Obtain one from this page.
  3. Connect your iPhone or iPad to the computer
  4. Open up Cydia Impactor and drag & drop the IPA file into
  5. Impactor will ask for your Apple ID and password. Enter them to continue.

The app will be installed on your iOS device. You should see its icon on your home screen. Notice how you can’t open it yet? There is one more step you need to do.

Open the Settings app, go to General > Profiles & Device Management. Find the certificate with your email address and tap Trust. Return to your home screen and open the Houdini app. Press the “Start” button to proceed.

Houdini will go through different stages such as escaping sandbox, post-exploitation, fetching packages, and ultimately present you with a usable screen.

The main screen will present you with two shortcuts: clean system and respring. You can start by tapping on Sources. This is where you can install customize themes and tweak different parts of your iOS device. Under Packages, there are three various options: Tweaks, Themes, and Utilities. Go through them and make the changes to your liking.

Once you found a theme that you like, hit the Apply button. As soon as the downloading process is completed, go back to the main screen and tap on the “Respring” button. It will make the changes for you.

Help!! I’m having trouble installing…

No worries at all. If you tried to sideload Houdini via Cydia Impactor and it shows an error like lockdown.cpp:57 or gets stuck at Verifying Application, then this tutorial should help.

What about failed escaping sandbox?

If you were able to open Houdini and hit the “Start” button but it came back with an error message, you should follow the on-screen instruction. In this case, it would be to hold the power + home button for 6 seconds to reboot then try to start again.

Usually, you only see this problem when trying to run Houdini on an incompatible iPhone or iPad. Remember that this app will only work on 64-bit devices and between iOS 10 – 10.3.2.
