How to root LG Optimus L3 E400 Smartphone How to root LG Optimus L3 E400 Smartphone? 
I followed the instructions on this webpage:
http://www.rootlord.com/2013/02/root-lg-optimus-l3-e400-smartphone.html.
But nothing happens, it says on the site that after the process is complete there should be an app in the app drawer called "Superuser" with a green icon, but its not there.

This is the model that Google Play displays: Vip MK LGE LG-E400

This is the output i get from the application:


Thank You
I tried using the same program and many others to root that phone none of them worked, except for Key root Master MOD (This app is in Chinese but it still works as I have used it my self and succesfully rooted my Lg e400f).

Instructions:


Download the Key root Master MOD. I uploaded it to my Google Website here. Scroll down to the bottom of the page and download the "Install.apk  
Sideload the APK
Click the second button Mulai Root and a popup will show 
Click the button that says root and another popup will show button in purple with 2 buttons (one red and one purple) 
Click the purple button 
Your phone should be rooted and have SuperSU installed 
Optional: Use a root checker to check if you actually have root privileges


This was the only root method that worked for me, as all the other ones didn't work.

You may see Stop Looking And Root Phone Here! youtube video. I didn't use this video for my guide but this shows you how to use the app (as the app shows interface in Chinese language).
