I don't know if this is the correct place for this information, but it is a gathering of mods, so I will post here.
I did the mod to remove the connection optimizer for Sprint. made the changes in PhoneFeature.smali, rename the apk to bak so it wouldn't run, went to Mobile Networks and the option was still there. Upon clicking on it, the Connection Optimizer ran??? What!? LOL. So, I looked back at PhoneFeature.smali and noticed there is a CSCFeature setting under the optimizer heading. I went to feature.xml and changed true to false and it removed it from Mobile Networks. I don't know if there is another way to run the app, but it looks like it is completely gone now. So, at least for LP on the Note 3, setting the CSCFeature flag, in addition to the mod, removes the Optimizer. Someone could try with just the CSCFeature change and remove the apk to see if that is the only change needed to stop it from working (I think it would be easier to just change the xml than do a smali edit). I may push my untouched Telecom.apk and see, but it will be a while. Anyways, here is the edit
Code:
<CSCFeature_Common_EnableSprintExtension>false</CSCFeature_Common_EnableSprintExtension>
This line already exists in feature.xml, just change true to false
