Default [Q] how to write in /sys/

Ok so here it is... have two Samsung androids. Well on my galaxy pocket plus(GT S5301) I simply tried the TSP FW update. Well it failed so I got on a quest to fix it. I found that the TSP FW is at /sys/devices/virtual/sec so on my galaxy trend (ace2x) the are files and folders such as tsp, touch key, etc. On the galaxy pocket only the switch and sdcard remains. So I can pull the files from my other phone but I can't push or paste to the pocket. Is the a way to push to that folder
Even root explorer can't paste there using read abd write.
Oh and the TSP FW UPDATE code is the *#2663#
