Default [Q] How to write AWB files in /sys/

hello, few days ago i got awb files from forumers, but i cant replace the file.

When i use ES File explorer with root browser and replace the file, it say permission denied, why?

When i use other Root Explorer, the path /sys/Android_awb_blabla... at top there it write "mounted as Read/Write", which means
i can rewrite it, but i cant, even with Root Explorer

Anyway to replace it ? Thanks

*SOLVED*

Actually just tick permission then its ok to replace
