Unity 4.6 | 4.7 AdMob iOS Crash

Hi, i'm using AdMob via Google Mobile Ads Plugin ( link ). It's working on Android, but crushing on iOS, right after unity splash shows up (does not reach my splash). I tested on: Unity 4.7.1f1 and 4.6.3f1 (IT'S WORKING in Unity 5.3.4), xCode 7.2.1 and 6.4, several versions of plugin and AdMob sdk, also some old without CocoaPods with manual framework integration. iPhone 4, iOS 7.1

Not working in new clean project without any references to plugin classes. Even if I delete all plugin files besides Plugins > iOS (.h .m files) and manually add GoogleMobileAds.framework in xCode. So something wrong with those files?

Problem occurs before Crashlytics initialize, so I don't have meaningful information about the error. No C# specific error in xCode console with script debugging enabled. Device log:
