How to Fix Cydia Impactor Errors When Jailbreaking iOS 10.1 – 10.2 With Yalu

For some of us who upgraded to iOS 10.1, Christmas came a bit early this year as hacker Luca Todesco just released his iOS 10 Jailbreak.

More specifically, this jailbreak utility called Yalu will support the following devices:

  • iPhone 7 on 10.1.(.1)
  • iPhone 6s and iPad Pro on any iOS 10 firmware

If you have an iPhone or iPad running anything below that, it’s quite sad to say that iOS 10.1 is no longer available for upgrade or downgrade since Apple just stopped signing them.

There are a few more things you should know:

  • Yalu jailbreak is no untethered
  • The tool comes as a .IPA file and you will need to sideload it

Talking about sideloading, we did a test drive ourselves as well.

Silly me, I made a few mistakes while I jailbroke my iOS 10.1 device using Yalu and Cydia Impactor. In this post, I’ll put together a list of issues that I went through and their fixes. Hopefully, that will help you guys.

http-win.cpp:158 Error on Windows

Since yesterday, a bunch of users has been getting this error when they tried to re-jailbreak their Yalu app using Cydia Impactor. The entire message goes something like this:

Peer certificate cannot be authorized with give CA certificates SSL certificate problem: self signed certificate chain

Luckily, Saurik was quick to update his tool to version 0.9.39 which fixes the cpp:158 issue that people encountered when they use Cydia Impactor for their Yalu Jailbreak. In addition to the bug fix, we also found a new feature called Cydia Extender.

If you ever receive this SSL verification error message on Windows, just update Cydia Impactor to the latest version.

Error Provion.cpp:150

Let me guess, you dragged and dropped the .ipa onto Cydia Impactor then you entered your default Apple email and password?

You almost got it. This error popup when you use the iTunes password that you always use. To fix it, just head over to this page, sign in, and scroll down until you see APP-SPECIFIC PASSWORDS.

Under that, click on “Generate Password…”. Give it a name and click Ok. Use that particular password to sideload your Yalu jailbreak.

Error Installation.cpp:42

This was a laugh out loud moment for me. I was so excited about the new jailbreak that I grabbed the wrong iPhone. Cydia Impactor couldn’t install the .IPA file on it since it was still running iOS 9.3.3.

If you see the Installation.cpp:42 error, it means that your device isn’t compatible (mostly due to firmware version).

And that’s pretty much it. After switching to the right iPhone and use an app-specific password, I was able to jailbreak iOS 10.1 using Mach_Portal, Yalu, and Cydia Impactor.

Unable to Open Mach_Portal app

After sideloading the jailbreak, you won’t be able to open its installed application right away. Take a step back and go to the Settings app.

Then, go to General > Profile(s) & Device Management > Developer App and Trust the application with your Apple ID on it. Head back to your home screen and you should be able to launch the “mach_portal” app.


The rest of this error message:


An invalid value ‘CY- mach_portal’ was provided for the parameter ‘appIdName’

And the solution to this is updating Cydia Impactor to the latest version. You should see a popup asking to update when you open the app. If it didn’t show anything, uninstall it and click here to download the newest version.

Runtime Error!

A lot of people seems to report the unknown Runtime Error! when signing IPA with Cydia Impactor. According to a user from Reddit, you will see two popups. One from Microsoft Visual C++ Runtime Library and the second will display the crash log.

To fix this issue, all you have to do is:

  1. Open the App Store and tap on the Search icon ten times. This will clear the app’s cache
  2. Restart your iOS device to free up some RAM
  3. Last but not least, perform a hard reset

Stabilizing Your Jailbreak With extra_recipe+yaluX

As you can see from above, with all those errors, it’s safe to claim that the Yalu jailbreak is not really stable. However, those who have a jailbroken iOS 10.1.1 no longer have to worry about such thing. Luca Todesco just updated his official Yalu site with a new .IPA file called extra_recipe+yaluX. This new jailbreak aims to fix any bugginess that users experience while using their iPhone.

The extra_recipe+yaluX was created by developer xerub based on the mach_portal exploit by ianbeer. If you still haven’t updated your iOS firmware yet, click here to download the new .IPA package (beta 1 as of writing this) and give it a try.

  13. Facing problem while jailbreaking 10.1. Cydia impactor shows completion of process but yalu app doesnt open 🙁 At last i deleted yalu app it is also not showing after jailbreaking too.

  16. Türkçe: GeneratingApplicationMap hatası veriyor. farklı bilgisayardan denedim tekrar aynı hata, telefonu resetledim tekrar aynı hata, iki faktörlü kimlik doğrulama iptal ettim tekrar aynı hata, çözüm yok mu?

    GeneratingApplicationMap gives the error. Tried from different computer again same error, reset phone again same error, cancel two factor authentication again same error, no solution?

  17. Anyone else that may be having a simalir issue… I have an iPhone 7 on 10.1 downloaded Cydia impactor and .ipa beta 4. I opened up impator plugged my iPhone into my PC then dropped the ipa beta 4 into the bottom of the two boxes. When everything was done I went into settings>general>device management>then clicked on the itunes > then selected the itunes login again to trust the application. Now this is where I ran into problems. I went to Mach_Portal but instead of a white screen it went black and froze that way for a good 45 seconds, then restarted my iphone 7. after reboot there were both the Cydia impactor and Mach_Portal apps and after trying to go to both Mach_Portal and Cydia impactor multiple time and getting “device storage almost full” it would reboot again. So I deleted the Developer App. and Mach Portal. I then restarted the whole process but instead of using the ipa beta 4 I used the “ipa beta 3” after following all the steps, everything seems to work (although I still get the device almost full pop up and I literally have nothing else installed). Just an fyi this is my first time doing a jailbreak, so just make sure you do your research. If anyone knows how to resolve the device storage almost full please feel free to chime in. Hope this information helps someone else with the same issue

    • This error meaning you have reached the maximum number of unsigned applications allowed, You can fix this error by Downloading extra_recipe IPA file.

      Instead of that, you can also use an online jailbreak method. No Apple ID, and no Cydia. “Silzee” website is the best no PC jailbreak tool available site I have ever seen.
      Try to fix your error by following one of above methods.
