Activating on Sprint after de-activating the device from Ting pushes OTA files for Hotspot and other features. Only when we see the yellow Sprint Spark boot screen, the Sprint ID app, Sprint zone, these options in settings come up. A ##786# or a ##72786# wipe will remove them. Applicable on HTC Desire 510 and Tribute also. Flash concerned PRL and make RUIM if available for Tata Docomo. Some Tata Indicom OMH SIM cards do not detect on Volt. Avoiding Boost and going in for SPR pre is a safer bet.
