WIFI TETHER APP
youngnex in post #144 and #156 confirms Wifi Tether Router to work on 720T (the app cost $2 in the app store, and it requires root permission). This has been confirmed working on MK5, NAF, NC6, & NG5 (dward3662 post 1132) with the following settings:
WiFi Channel: 1 or 6If you are having problems losing connection try changing the WIFI Channel from 1 to 6 or from 6 to 1. Originally, I had to change the channel to 6 to eliminate disconnects. Worked great for months. Installed a recent Wifi Tether Router update (5/3/14) and had to change back to channel 1 to eliminate the disconnects.
No Firmware Reload: UnChecked
Wifi Mode: WiFi - N

judgeduck post 367 has confirmed the same hotspot solution (wifi teather router) works on NC6 with root. "
I am confirming that the same settings for WiFi Tether Router app referenced in post #1 are also good to go and working for Sprint rooted firmware L720TVPUBOA3 as well!
