[H] Can't make changes on System/usr/keylayout READ-ONLY
I've successfully rooted my table, installed Supersu, TWRP and even tried the CM11 ROM in it.
The main problem is that I want to add/change some files on the /system/usr/keylayout folder so I can configure correctly my xbox 360 wireless controller (I'm having the spin buggy thing on some games).
But whenever I try to make changes in that folder using "ES File Manager" (granting it SU) It just pops up "Try again, this folder is read only"
I tried changing it through the Terminal Emulator through these steps:
mount -o remount,rw /system (or mount -o rw,remount /system its the same)
Didn't make any difference...
Can anyone help me really hard here?
I'm now with the LG Firmware 50020D and android vers 4.4.2 (rooted)
