Samsung SPH-L720 Galaxy S4 Sprint

Phone Pre-Setup:

PLEASE NOTE: If the device is on the Android 4.3 OS, you will be required to get the SPC/ MSL for the device before flashing. Since the update, Houdini will not be able to automatically unlock the device without you manually inputting the SPC/MSL during the flash. In most cases, customers may call Sprint to get the SPC/MSL for the device. Alternately, a handful of applications can be found online that may assist with getting the SPC/MSL as well. (Please note the app, "Get My MSL" will only work on Android 4.1.2 devices.)
