Firs I want to say that my nexus s is rooted with the latest CWM (or at least latest enough to install 4.4). First I installed 4.3 from slimroms. One month ago I installed 4.4.2 again from slimroms. All is fine except that with 4.4 I have BIG battery drain. I am thinking of rolling back to 4.3. But I want to do a complete backup of the OS with the apps and settings - all. In case I don't like 4.3 I want a .zip image so I can install back my backup and everything will be just like before. So is this possible or not? I know there are apps that can do a backup but how deep is this? Is it only the apps, or the apps and settings, or u can do only OS image? CWM can do backup too but since I've red it does backup only for the OS -no apps no settings.
Any tips will be appreciated.
