My solution will work to all of u. Atfirst make a folder named "obb" in "sdcard/Android/" & then follow the steps below.The main problem is all of u are placing the file com.gameloft.android.ANMP.GloftM4HM.obb file to "sdcard/Android/obb" but u have to place the whole folder com.gameloft.android.ANMP.GloftM4HM to "sdcard/Android/obb" and to get the meltdown update u have to make a empty folder named "obb 1100" in "sdcard/Android/".Hence open the game first time online and then u can play offline from next times.OK thank u and fell happy to say if u still facing problems.
