Device: Lt18i I copied the xperia keyboard apk (textinput-tng.apk) into the /system/app of my MIUI 4. But the keyboard FCs whenever i select it. I dont know if i need to change any permission settings. I found another thread on XDA, (http://forum.xda-developers.com/showthread.php?t=1706482), but i did not understand what the guy meant by changing the permission to 644. Also they are talking abt the stock xperia ICS rom. Can someone pls help me make this work?
