[Q] Help, CM11 WhatsApp+ Icon

Hi. I'm using CM11 on my Note 2 LTE, with Gem Flat theme.

I have use ApplicationReader to get the ComponentInfo{com.whatsapp/com.whatsapp.Main-01} and edited the appfilter xml file for the theme. However WhatsApp+ icon refuse to change.

The WhatsApp+ that I am using: http://www.osmdroid.net/2015/01/What...s-No-Root.html

The theme I am using: http://forum.xda-developers.com/show....php?t=2467075

I have change icon of several other apps like Google Inbox, Dance Up etc and they work.

Would really appreciate any insight into getting the WhatsApp+ icon change.

Thank you :)
