epst to work on the sensation 4g

[Razo559]

so my last phone was the evo 4g and there was certain things you can do by accessing epst for example by dialing ##3282#

well i wanted to know if there is a way of getting this to work. or if its even possibe.

I have the epst.apk file that i would always use, its from a 2.1 rom.

so far i've tried the temp root then installing root manager and moving the file to system>app>epst.apk and installing it but its not as easy as when the phone is completly rooted.

the attached file is the file i would use with my evo
