Hi, I'm currently on TextNow and I went ahead and loaded CM as my daily driver but I still wanted the stock TextNow app etc...
TextNow phones come with a system app specifically designed for our Moto E. I just took that app and libs, plus the stock apns file, then modded the sprint eri file, fixed LTE and put it in a flashable zip.
1. Uninstall the market TextNow app (If installed)
2. Boot into your favorite recovery and install the zip file below.
Note: This is for MM 6.0+ ROMs
