Hello, I could not fully understand your problem. If you could write what your Samsung model is, what your Android version is and what you used to modify the qmg file, I could help you. Can you try using Total Commander?

/system cannot be mounted rw on stock rom, use a magisk module to edit /system/media systemless-ly
