Then install these APKs:

adb install com.google.android.gms-6.6.03_(1681564-036)-6603036-minAPI9.apk
adb install GoogleLoginService.apk (Version: 4.4.4-1227136 ; Notice: this number seen in Application Manager in android)
adb install GoogleServicesFramework.apk (Like above line)
adb install com.android.vending_6.1.12-80441200_minAPI9(nodpi)ByMe.apk (Version: 6.6.03(1681564-036))

These are not necessary probably (After we added that signature), but do it to sure:

adb shell pm grant com.google.android.gms android.permission.INTERACT_ACROSS_USERS
adb shell pm grant com.google.android.gms android.permission.READ_LOGS
adb shell pm grant com.google.android.gms android.permission.WRITE_SECURE_SETTINGS
//adb shell pm grant com.google.android.gms android.permission.ACCESS_DOWNLOAD_MANAGER
//adb shell pm grant com.google.android.gms android.permission.CHANGE_CONFIGURATION
//adb shell pm grant com.google.android.gms android.permission.MANAGE_USERS

Or

Add these to your init file:

#ByMe
pm grant com.google.android.gms android.permission.INTERACT_ACROSS_USERS;
pm grant com.google.android.gms android.permission.READ_LOGS;
pm grant com.google.android.gms android.permission.WRITE_SECURE_SETTINGS;
pm grant com.google.android.gms android.permission.WRITE_SECURE_SETTINGS;
#pm grant com.google.android.gms android.permission.ACCESS_DOWNLOAD_MANAGER;
#pm grant com.google.android.gms android.permission.CHANGE_CONFIGURATION;
###

If above solution doesn't work, to add extra permission to these prebuilt applications:

include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := apkname.apk
LOCAL_MODULE_CLASS := APPS
LOCAL_PRIVILEGED_MODULE := true
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_MODULE_PATH := $(TARGET_OUT)/priv-app
LOCAL_SRC_FILES := apkname.apk
include $(BUILD_PREBUILT)

This snipped code, copy APK to /system/priv-app, to be eligible for system permissions. For mor information: http://stackoverflow.com/questions/40397443/how-to-add-extra-permission-to-a-prebuilt-application-no-source-code-in-aosp

Now run google play store application; not anything else. Login, Enjoy!
