Info 2 Tested Roms on SPH-L720T

I successful install universal Carbon Rom and latest TWRP on the Sprint SG 4 Tri-Band variant. I do not own the device but the only thing I could find was that the MAX CPU speed clock on this Rom is 1.8 GHZ, do not know if that is normal. It will display DIGITAL ROAMING even thou it is connected to the Sprint Network.

Universal Carbon Rom what is working
  • Bluetooth
  • WiFi & USB tethering
  • Camera
  • Sprint LTE 4G internet
  • Makes and Receives Calls
  • Speaker on call and regular speaker

Broken
  • Display for Carrier Name (DIGITAL ROAMING)

Not tested

  • Google Wallet

APPS That are working
  • Comadose v3.5
  • Xposed Frame work
  • Gravity Box [KK]
  • Wanam Xposed
  • Network Speed Indicator
  • more...

Thank to Carbon Rom Team, @teamwin, @Goddly

Be careful testing TW roms and always make a nandroid backup and have a copy of the official tar for Odin flash just in case. I have not tested any TW roms.
