You can stop server update with Xprivacy it has all the features(check my former thread).
If you don’t have Xprivacy installed
Install Hosts Editor – – – >
(Host Editor is used to install host address, redirect or block them)
Free Download APK File of the Hosts Editor v1.4 for Android – APK4Fun
You must have Root Previledges.
Open host Editor, click the Right Top Corner , the “+” Sign and input
Those tweakware addresses in the screenshot, all IP Address should be 127.0.0.1 (that’s your phone IP)
There might be other server address I don’t know about if you have it input it.
Note: You won’t be able to access Tweakware Website in your browser, so if you would like to download the new tweakware update you have to delete all the addresses in host editor or just update through the Google store.
