Thanks for the reply. I've installed them again, tried, and waited hours for the silent update.

$ adb shell pm list packages -f | grep -i google

However, it is stuck in the "Sign in" button in Google Play (tried also to sign in in other Google apps, like Gmail and YouTube, similar). If I check logcat, I see the below (Errors only):

"Find my device" is also activated as device administrator, so that supposed to give more permissions.

You might be right about just installing these, and they supposed to work, because the app they removed recently (Lznet) didn't seem to unlock the bootloader or root the device, and people reported it working. So basically we should just copy what it does, and it supposed to work (unfortunately I read some articles where they said just installing the apks to user space is not enough, there are special permissions which only apps installed under /system can be granted to - the people you're referred to as idiots :D ) . Do you have any other suggestion what to install or set?
