Untrusted Enterprise Developer Error on iPhone? Here’s a Fix

Many iOS users often see the popup that says, “Untrusted Enterprise Developer” when trying to install apps outside of the App Store. These are the applications that were not allowed by Apple due to their term and conditions. But in most cases, they do no harm to our iPhone and iPad.

If you’re new to the whole emulators and third-party apps thing, this would be the first or second error you see. But that’s fine because there is an easy way to fix the untrusted developer popup.

Why does this error appear in the first place?

Like I mentioned earlier, the popup only displays for apps or emulators that have been installed from Safari or sideloaded via Cydia Impactor. Since regular users are the one who installed them, they’re responsible for the apps they downloaded to their device. As a result, Apple added the warning to iPhone and iPad running iOS 9 and higher.

You will see the complete notice below.

Untrusted Enterprise Developer” along with iPhone Distribution….has not been trusted on this iPhone. Until this developer has been trusted, their enterprise apps will not be able to use.

The fix to this issue is relatively simple. If you believe the app you installed will not inject or do any harm to your iOS device, then you can tell the system to trust it.


How to Fix Untrusted Enterprise Developer in iOS

After downloading the app, don’t open it yet. Follow the instructions below first.

  1. Go to Settings > General > Profile
  2. On this page, you may find several enterprise apps
  3. Choose the app corresponding to the app that iPhone doesn’t let you open
  4. Tap on the Trust button and another one to confirm

Now go back to your home screen and try to open the application. You shouldn’t have any trouble opening it since its profile has been signed personally by you, the device owner. This Untrusted Enterprise Developer prompt is another great way to hardening the security of your iPhone. This will allow you to trust non-App Store apps manually.

Next time if an emulator or app doesn’t want to open, you know the reason why.

For iOS 9.3.3 Users

Another recent situation with this error would be the new Pangu Jailbreak for iOS 9.3.3. You can now download the jailbreak utility and initialize it to install Cydia without a computer. However, to open the Pangu app, you will need to use this method above before opening it on your home screen. I hope this help and enjoy!

Profiles or Device Management is Missing on iOS 10?

People get panic when they unable to find either option in the Settings app. Without trusting the sideloaded app, users won’t be able to launch it. Their application would just crash upon opening.

Not to mention, my comment sections has been blowing up with people reporting that their Profiles or Device Management is missing from iOS 9 / 10.

I guess it’s time to add an extra section to this post on how to fix such issue.

How to Find Your Profiles and Device Management on iPhone

Sorry to break it to you but there is only one place where you can find the Device Management page, which I already mentioned above.

If you can’t find one of the two, that means the profile wasn’t installed in the first place.

Unlike other iOS settings, the device management on your iPhone will become visible only if you have a profile installed (in this case the app that you sideloaded using Xcode or Cydia Impactor).You might want to re-check to see if there was anything wrong that could occur during the installation process. I suggest checking out this post and this one as well.

Other suggestions:

  • Restart your iPhone
  • Re-install the app from your computer

Let me know how it works out for you.

Unable to Verify Your App?

That seems like a rising issue for many people. I’ll use the YouTube++ app as an example. It stopped working and prompted me to trust the application. I then get redirected to the Profile page with a new option called Verify. Now, this is a real headache because verifying an app in this instance doesn’t do anything.

If I were you, I would go with the sideloading option. The Verify screen often comes up when you install apps directly from Safari or third-party App Store. When you download the .IPA file and install it via Impactor you’re less likely to face this problem.

Another thing you can do is remove the problematic app and re-install it.

QuickTrust tweak

The “Trust” button on our iOS devices can be complicated to find for most users. A new jailbreak tweak named QuickTrust aim to solve this problem. It will simply add a Trust button directly to the popup the first time you see it. That way you don’t have to waste your time going into the Settings app.

All you have to do is tap Trust when prompted with the warning. You can install QuickTrust from the BigBoss repo for free.

The More You Know: What Are These Profiles For?

Profiles are small configuration files that gets installed on your iOS device to install an app on the home screen, which sometimes is fully web-based. A profile also gets installed when you sideload a modified .IPA file using Cydia Impactor. Not all iOS profiles are the same as some don’t provide us with any app icon, they just give us some additional functionality. Some profiles can even come from Apple.

Type of Profiles:

Apple Beta Updates: If you enroll in the Apple Developer program; which is $99 a year then a special profile will be sent to you. When this happen, you will start receiving beta versions of any new major firmware that the company plan on releasing to the public.

Tweaked apps: If you don’t like how certain apps like Facebook or Instagram works, you can install a modified version of them which usually enhance the experience or add more features to the official app. You will need to use your Apple ID and password to install them to your iPhone.

Emulators: Some apps like emulators certainly violate Apple’s term of service. However, they rarely do any harm, so you can still install them from the web. (I recommend checking out Delta)

  1. Hello, I have a Verizon and when I go into settings it doesn’t have a General selection thing, is there another way I could do this?

    • Sad to break it up to you, but you are now stuck there, you must live the harsh weather environmments and with the monster, Ed Lee, best thing to do is to deal with it and live with it until you finally get the hang of it.

  2. after I give trust I can use the app but after I sync with iTunes it askes me to verify again wnich isn’t working.ps tell solution

  3. I allowed the trust through this method, then a day later the error came back. The only options in profile were ‘verify’ or delete’

  4. Same with me I installed notability from on safari and it worked at first but then like a week later it untrusted the app and my only choices were “verify” or “delete”

    I tried deleting it but I reinstalled it and the same process happened

  5. why is it asking me to verify app using my network connection? is the app developer trying to use my internet? is this normal?

  6. I am unable to find the trust app page with IOS 10, when in trust certificates there are no options, no other pages show me the app settings with these options either

      • How is a profile installed? this is new to me. I had the same hack installed in 2016 but its harder for me to install now windows keeps coming up with the same error saying certificates arnt trusted so Cydia impactor won’t complete its task

  7. Mine just started doing it again! Any new fixes ? Don’t wanna delete in case my game data gets lost in the process. 🙁 I’m so close to finishing the game

      • My stuff just started saying this today too!!!!! I already trusted my apps now all I have the option to do is “verify” and when I click “verify apps” it DOES NOTHING!!!! I downloaded so much music, too much music to just delete. I have to steady wifi or data. This is bullshit.

  8. When I go to push trust in the tutu app and Spotify Premium it’s says back blah connect to the internet and try again ..Thing is I’ve been using Snapchat and the internet and it all works but when u push the trust it tells me the same thing ..Any ideas ??

    • A lot of apps got revoked in 10.3.1. You might want to see if it was downloaded successfully in the first place.

  9. Hi. I installed the tutuhelper for Spotify ++ on my IPhone 6. I trusted and verifed but I uninstalled the app the next day but when I go into settings I don’t have device management I have regulartory filled with other company names. How do I delete that and go to my regular default for device management?

  10. Cydia impactor creates a 1 week profile if u add an untrusted app via pc.. is there any way to create a permanent profile?

  11. “Already installed as incompatible team.” I haven;’t seen anyone else with my error message. I did it exactly like the videos and d instructions, but it isn’t working.

  12. Look, i’m going to be honest, i have a pirated minecraft app and it won’t verify. I’m a minor and don’t have money. i’ll donate 100$ to those f*ckers when i start making money but i need minecraft now. how do i get around this crap? it isn’t working.

  13. I’ve been using Delta Emulator for over a week without problems. Then tonight it gives me the “Unable to Verify” error and I cannot even get it to open the app. It won’t verify when I go into Device Management either. Any suggestions? I’d rather not lose all my game progress by deleting everything.

  14. Thank you for the reply. Once I reinstall the IPA, will this be a recurring problem? Is there any way to save or export the data now? If not, how can I save it when I get it running again, for future reference? I sure appreciate your help.

    • The problem will occur as soon as the certificate expires. I think there is an option inside Delta emulator that will allow you to save and export your game data.

    • I have an iPad mini 4th generation and suddenly all my apps I had working and verified in the past unverified and won’t let me re verify and on top of that one of the apps has way over 200 songs downloaded and I don’t want to have to go through the process of downloading those all over again plus lose all the data in the GBA4iOS emulator if I undownload it and re downloaded it

  15. I’ve downloaded tutuapp for 4 days and now and its saying to me that I had to verified it. Instead, I deleted pokemon go and tutuapp and thought of reinstalling it. Unfortunately I can’t download tutuapp anymore. I tried to reset the network but nothing happened. I’m not sure what to do anymore. Could please help me out or give me a fakegps for ios?

  16. I downloaded an app off of the TutuApp and it was working fine after I approved the developer. Now all of the sudden I click on the app and I can’t play it until I verify the app. So I went to settings and went to general-profiles- and then clicked on the app developer. Next I clicked “Verify Apps” and nothing happens!!!! Help!!!

    • I had the same problem!! But a few things are different… . I got a app off of AppEven . It was working well and after 1 or 2 months it said “ vertify this app “ . I went to the iOS general and I clicked vertify but it did not do nothing nor did it fix the problem ! I hope someone helps me fix this problem plz!!!!
