Unify the order of log to store value

Unify the order of log to store value

- Issue:
Each functions have different order of logic for storing value.

- Solution:
In previous code, some functions first stored file and then changed the
memory. However, some other functions did the reverse of it. So, this
patch unifies the order of logic for storing values in each functions.
Through this patch, all functions will store the file first and then
update the config struture on the memory.
