You need to reboot your phone (If you installed everything right with Xposed and Wanam.) I thought the same thing at first, but after a few reboots, the custom icon left and now says Official in status. I have done all root methods for this phone and Kingo is by far the best one, you just need to retry and make sure you follow each and every instruction to the tee. Not flaming, just telling you what helped me and others. Thanks man,,,,already did that after the root. for some reason its not working no matter what i do. worked before on the other root method but not this one
edit: ok now im pissed off(excuse the french). i have factory reset everything and fully unrooted. i can not get the custom icon off my phone. gonna re root with the other way that i was before. ill report back. as far as im concerned this way sucks
GOOD LUCK
