You only can leave stock one on if you change name.There both the same name.So I found a stock mms that you can theme yourself within the app.Give me a little while ill post screenshots of everything.Are you rooted and did you deoxed your rom? Are you using stock rom? If you didnt deoxed your apps I think youll keep getting force closings after changing phone, contacts, and mms.I tried to change those when I was odex and thats what happened.I just stepped on a giant nail and I cant walk so my plans arent happening now. I'm going to play around with some things and let me see if I can fix. I'll pay screenshots also. Please answer questions so I know what you have. Thanks
I am rooted but pretty much stock otherwise. I have not deodexed but I have seen several posts on how to do so. @blaz1nr has a couple mods and the one for the S5 conversion has a deodex_me.zip.
Thank you so much for your time.
