So here's how it works with the new Google+ feature:
Apps that want to sign in using Google+ are verified from Google Play services by using the developer signature. With the patching of an app, the original signature is lost and the app will not be able to authenticate.
I have built a workaround that lets us spoof the original developer signature directly in Google Play Services. As the signatures have to be hardcoded in Google Play services, each new signature automatically results in a new build. That's why I will try to group the signatures and release one build a week or so.
Now it's up to you. Post the signatures of your Google+ apps here and I will implement them into Google Play. I've updated the first post with some new instructions and a new version of Google Play services that supports patched versions of Youtube and Clash of Clans (GMAPS patcher or LUCKY patcher will do).
From the first post:
Cobalt SignatureTool
This is a helper app to gather signature information from apps that require Google+ login.
Instructions:
1. Install an unpatched version of the app that uses Google+ Login
2. Run SignatureTool, select the app and press "TO CLIPBOARD"
3. Post the signature information here in this thread.
3. I will then add your app to the Google Play Services whitelist
Please only post one signature set per package.
