For both files permissions should be rwe-r-r
If it still don't work do the copy paste commands in emulator which is in first post after this..
It should work..I have successfully got my lockscreen and power menu button by this on my grand Quattro running JB 4.1.2
This is the only method to get back those...even u try reflashing your stock firmware u won't get it.do it again without mistakes in code..
In the code the first two line is to remove those two corrupted files and the next two steps is to add those two files and the following codes is to set permission which it needs minimum 777 permissions to work.....
so if u get error like no such file directry exclude two lines below su.
