The original CSC code is located in the file: /efs/imei/mps_code.dat
The current CSC code is located in the file /system/csc/language.xml
CSCs are located in the base directory: /system/csc under their own subdirectories.
So MM1 (CSC for M1) is located at /system/csc/MM1 and has these subdirectories and files
