I don't have CWM so I decided to do it manually (sorry I'm quite new to all this)
I copy the contents of the system folder in the zip to my phones system folders and set permissions to -rw-r-r
(copied files: the one in etc/permissions and the one in framework)
Then I rebooted and it was optimizing the apps to new android version (is that because of the framework adjustment?)
Now the playstore says that my device is not compatible (Xperia M SS 15.4.A.0.23)
Is there anything else I need to do to get this working, or do I just need to find the themes somewhere else?
