Enterprise app deployment doesn't install on iOS 8.1.3

Question

After updating iOS 8.1.3, I tried to download, but getting error \"Unable to download app\" and \"could not be installed at this time\" mes

Answer 1

I have sovled this problem.

1. Since Apple has changed provisioning profiles, please RENEW the provisioning profiles (File 1) and copy it into the "Payload/".
2. Make sure there's a Entitlements.plist (File 2) in the "Payload/", and this plist file MUST be PLAIN TEXT which is created by a text editor.
3. Make sure there's a Info.plist (File 3) in "Payload/", and this is created by XCode;
4. Copy the Entitlements.plist (File 4) anywhere else except the "Payload/".
5. Be sure "Bundle identifier" in File 1-4 should be the same.
6. Use this Entitlements.plist (File 4) to Re-Sign the IPA file.

You can resign it like this

codesign -fs "iPhone Distribution: Your Company Name" --entitlements=/Users/SenTR/Downloads/codesign/Entitlements.plist /Users/SenTR/Downloads/codesign/Payload/Your_Project_name.app

Entitlements.plist sample

    
        application-identifier
        PREFIX.yourappBundleID
        aps-environment
        production
        get-task-allow
        
        keychain-access-groups
        
            PREFIX.yourappBundleID
        
    

If you know Chinese, this will be helpful.
