This is my First post So sorry if i make any mistake of my Language.........
Be ready to Root ur elanza 2 I have done it after trying many methods Its really work
(1) install"Universal ADB drivers" to ur PC (Tested on Windows 7 only)
(2) Restart ur pc
(3) Install "Root Genius 1.9.6 (if u don't find this version install any version and then update this).
(4) Connect ur Elanza 2 with enabling usb debugging.(Also connect ur device as MTP device)
(5) Now open root genius.It will detect ur phone
(6) Click on Root Button
Note: (1) After rooting this king user icon shows in ur phone I have tried many times for Superuser but there is no binary update for SU.
So no need to install SU. king user provide u root access.
(2) If Root genius not detect ur phone Connect ur phone as "USB STORGE"
Don't forget To hit "THANKS"
