Default [Q] Accidentally Deleted DownloadProvider.apk from Galaxy Core

I have accidentally deleted DownloadProvider.apk from my Galaxy Core. As a result I am unable to Download apps from google play.. It stucks into "Downloading..." I tried to push DownloadProvider.apk app (of galaxy fame 4.1.2) into system/app of my core.. But that does not work.. Can anyone provide me the SecDownloadProvider.apk and the odex file of Galaxy Core? Or a way to get back to the initial state?
