Hello dear users of our dear xiaomi, I would like to ask you for help, I really like to study systems and look for possible bugs or ways to help them improve, so I would like to ask you for help on which programs to use to decompress and compress again the miui files, called "system.new.dat" and "system.new.dat.br", if you can also help me, I would like to know what other files can be edited to access the ROM code, Thank you for understanding and I appreciate whoever helps me.
