Code resign using Ipa not failing with Installaation error-IOS

Question

I am doing it through command line .The code is from third party developer.Previously it is working.Now it says Installation failed.

I use following code to resign

1. Unzip the .ipa file unzip app.ipa

2. Delete the current code signature file rm -rf Payload/MyApp.app/_CodeSignature/

3. Add in the new provisioning profile cp ~/Downloads/AdHoc.mobileprovision Payload/MyApp.app/embedded.mobileprovision

4. resign the code codesign -f -s "iPhone Distribution: Company Certificate" --resource-rules Payload/MyApp.app/ResourceRules.plist Payload/MyApp.app

5. rearchive the app into an .ipa file zip -qr app-resigned.ipa Payload/

You also need to resign Framework, Dylibs, Appex,... files too.
But for best way to find problem of install, open XCode->Device and select your iphone to view log message when install failed.
