mach_portalfix.ipa – Fix All Cydia Errors on iOS 10.1-10.1.1

If you installed any bogus tweak, Cydia will not work as expected. We can fix this by using a modified version of Yalu jailbreak. Here’s what you need to do.

We will use modified mach_portal package (mach_portal fix IPA) to install Cydia first. This will fix all your Cydia errors. Remember YaluFix? This is the iOS 10.1.1 version of that file.

If you are able to SSH into your device, use this tutorial to manually install Cydia.

This method comes in handy when –

  • mach_portal is not able to install Cydia on your device.
  • You are not able to manually reinstall Cydia via SSH.
  • Cydia is throwing a lot of errors such as DPKG Locked error.
  • Cydia’s filesystem is corrupted.

This will work only if you have a device running iOS 10.1.1. If you have an iOS 10.2 device, use YaluFix.


  • A compatible device running iOS 10.1.1
  • A computer running Windows/Mac/Linux
  • Download Modified mach_portal.ipa
  • Download Original mach_portal.ipa
  • Download Cydia Impactor

How to Fix Mach_Portal Not Installing Cydia on iOS 10.1.1

Step 5 Go to Settings > General on your device. Scroll down and open the Device Management section.

Step 6 Select Trust Profile option.

Step 7 Unplug your device from the computer.

Step 8 Start mach_portal and it will show a white screen and then exit. Let it finish.

Step 9 Do not open Cydia at this point. Delete the modified mach_portal IPA file you just installed.

Step 10 Install the original mach_portal IPA file with Impactor. Read this guide to do it.

That’s it. Cydia will now be installed successfully on your device.
