Hello friends many people have questions about changing the android version of this tutorial I will teach this is very simple and almost numca be errors ... Before you begin the tutorial is recommended root. We go to the tutorial:
1. Install Root Browser Lite download here:http://adf.ly/BedOf
2. After running the "Root Lite Browser" go to the system folder and then run the "build.prop" found in this folder do not forget to run on "RB Text Editor".
3. When running a search online "ro.build.version.release = 2.3.6" 2.3.6 if you have the android or "ro.build.version.release = 2.3.5" if you have the android 2.3.5.
4. In this line changes the numbers "2.3.6" or "2.3.5" for anyone such as "4.0.4"
5. After you save the modified file and restart the phone.
6. Go to settings / about phone and enjoy your new version of Android :-) remembering that it is not the real one is so personalized.
