Need Help Sprint Banner!

Hey does anyone have a viable way to change or remove the carrier banner name. I want to de-sprint my phone's lock screen.... I have tried everything I could find on several different forums including this one. I have tried searching for the CDMA work shop and all that i could find is the trial one that is missing the NAM tab. I have tried QPST and I get to Read From Phone in Service Programming and I get the message "Roaming list receive Failed". Today I tried the APK multi-tool. I de-compiled the framework-res.apk and modified the res/xml/eri file then compiled that as a system APK file. I inserted that file using the TWRP recovery filer manager. All of this and NOTHING. I spent a lot of time on this and learned a few things except how to change the carrier name.

I am using:
Rooted
Samsung Galaxy Note 2
Model: SPH-L900
Android Version 4.1.2
I have been switching between the Stock Rom and the H2O Rom

Thank you
