EPST Change Unlock Code

[stevedusa]

Ya can't change EPST on Sprint devices, unlike VZW devices they are all six 0s.

You need to find your own MSL code by doing some registry editing and maybe, 30-40 minutes.

Where was the instruction I can't find it but what I remember was, change a registry command, wait for 20 minutes, check if a file exist, change the registry back and wait the same amount of time, then search that file for MSL and there is your unlock code.

Anybody has a link to that post?
