Do you have an MTK device with no further updates and stuck on ICS? fear not! follow this guide and the JB easter egg will be yours!
This app is not developed by me
all the credits goes to iamareebjamal the one who made the guide and app originally
1)get the Framework.jar from your ROM
2)decompile the jar
3)go to /smali/com/android/internal/app/ and replace the PlatLogoActivity.smali with the one in the attachments
4)thats it! recompile it
5)download this app and push it along with framework.jar or create a flashable zip for both!
6)app should go in /system/app and and framework.jar to /system/framework
Now go and enjoy the easter egg
I've already made this flashable zip for stockrom v2 of micromax a89 so people who want to try it can download stockv2_JB_easter_egg.zip from attachment and flash it via recovery!
