How to Make mach_portal Jailbreak Stable on iPhone 7/7 plus

Now that mach_portal seems to be stuck in the beta stage since forever, we must make it more stable. Let’s find out how to do this.

Is mach_portal iOS 10.1.1 Jailbreak Stable?

The mach_portal jailbreak for iPhone 7/7 plus is plagued with a lot of issues and errors. As it’s still stuck in beta version, manual actions are required to perform certain functions.

Here’s what you need to do manually.

  • Manually Start Substrate after each reboot.
  • Manually restart Springboard as and when needed.

Even maintaining the jailbreak on your device properly is quite a chore. Here are a few of the problems that persist on this jailbreak –

  • Random reboots
  • Relies heavily on user intervention
  • Broken backboardd
  • Kernel panics

We will fix these issues and make mach_portal a whole lot stable and easier to maintain. If you haven’t used mach_portal jailbreak already, follow this step by step tutorial.

As you know, the developer of Yalu jailbreak is no longer working on a jailbreak. Thankfully, other developers are actively developing unofficial fixes for all errors found in Yalu jailbreak.

This tutorial has been long overdue. So let’s get right into it!


  • A jailbroken iPhone 7 or iPhone 7 plus running iOS 10.1.1
  • Cydia Installer

How to Make mach_portal iOS 10.1.1 Jailbreak Stable on iPhone 7/7 plus  

1. Install Order 66 Substrate Fix for Yalub3

Order 66 Substrate Fix for Yalub3 enables Cydia Substrate and reinstalls Anemone and Rocketbootstrap. It is based on command line interface, so you require MTerminal terminal emulator to run it.

With Order 66 enabled, you no longer need to enable Substrate manually. It will also fix the functionality of LaunchDaemons with mach_portal iOS 10.1.1 jailbreak.

The correct procedure of using Order 66 is –

  • Boot your iPhone 7/7 plus.
  • Start mach_portal
  • Enable Order 66 via MTerminal.
  • Respring.

It improves the stability of your jailbroken iPhone 7 or iPhone 7 plus manifold.

Note – If you have already installed Substrate Fix, remove it before installing this fix.

2. Install iOS 9 Respring Fix

It is another great fix for iPhone 7 users. It is completely fine to install it alongside Order 66.


They don not conflict and increase the stability of your device.

Note – If you have installed Order 66 Substrate Fix, there’s no need to install iOS 9 Respring Fix separately. The latest of version of Order 66 (1.5.1) comes integrated with this fix.

3. Install CydiaRespringFix

Order 66 is a great tool but it doesn’t fix backboardd. This is where CydiaRespringFix comes into action.

Enjoy your Stable iPhone 7/7 plus Jailbreak

Even though this is not an official fix, you will still notice a huge difference. Your iPhone 7 will be more stable than before.

untethered jailbreak

As mach_portal isn’t open-source, it’s unlikely we will ever get a final jailbreak for iPhone 7. If you have an iPhone 7, these tweaks are your best bet right now.
