Does anyone know do something like this?
https:\redfern.me/bypassing-root-detection-in-three-intouch/
http:\bertonjulian.github.io/2015/01/30/root-detection-bypass.html

With this app?
https:\play.google.com/store/apps/details?id=com.orange.es.orangetv&hl=es
APK Download: https:\drive.google.com/file/d/0B_98s430aqHGcTdBQmhfV0VyLW8/view?usp=drivesdk

I decompiled the application into Smali using apktool, but i don't understand smali code.

Thanks in advance !!
