I recently reverted to factory settings on my rooted huawei u8185 due some problems i faced with a nonmarket app and when i rebooted google play store just wasnt there. so i downloaded an apk off the internet and installed it but every time i open it it gives an error message:"The application Google Play Store (process com.android.vending) has stopped unexpectedly. Please try again." i checked if download manager was working and it is. im clueless.
