What will happen if I "Clear data" for the "Settings" app? (com.android.settings) I'm on a stable (Installer) build of Cyanogenmod 11 on a Galaxy Nexus, and for a while I've not been able to access 'Settings' at all - tapping on it to try to open it, gives me a "Unfortunately, Settings has stopped." crash.

I'm not a fan of unnecessarily wiping and re-flashing ROMs unless I absolutely have to - and I've got an idea, which is to 'Clear data' for the 'Settings' app (com.android.settings) and maybe that will make the crash go away and me be able to finally access Settings once again.

But what will I lose by doing this?

Will I lose important settings such as my (finely tuned) customised home screen icon layout, or my saved Wifi network passwords? Will it even delete my saved Google account(s) in the OS and possibly cause havoc as a result?

And furthermore, Could backing up the 'Settings' app in Titanium Backup Pro (then restoring), be a solution to fully restore the app's settings if it does?
I did it a few days ago for the same problem (CyanogenMod M8 for i9100):


I didn't lose anything;
It fixes the problem =)
