Please donate to support OMA and CrewRKTablets firmware work, thank you !

Hi guys!
Sorry for my bad english
I installed 1.3.3 version on my GoClever R83.2 (Mediacom 875S2) and brightness adjustment not worked for me because system trying to write brightness level to
/sys/class/backlight/rk28_bl/brightness
istead of
/sys/class/backlight/rk30_bl/brightness
I have mounted system.img to my file system and using grep I found this path using in compiled library /system/lib/hw/lights.rk30board.so
Then using HEX editor I replace only two bytes (in text: 28 -> 30) and IT WORKS!!!
Now I have not time to build patch, but may be one of you can do it?
Download and replace your lights.rk30board.so
OR
Flash your device used patched system.img (1.3.3 Oma's image. only this lib replaced)
ACHTUNG!!! Don't forget: you must set permissions to this file!
it possible from terminal or via adb: chmod 777 /sys/class/backlight/rk30_bl/brightness
Enjoy!
Tomorrom I will try to build patch for using via CWM
The following users say thank you to uncoder for this useful post:

Cool. Well done!
I can do a CWM fix if you are ok with that?

Great find uncoder.
Just thinking about another way to fix the problem without patching files, would it also work by making a symlink from /sys/class/backlight/rk28_bl/brightness to /sys/class/backlight/rk30_bl/brightness ?
Cheers.

@up in init.rk30board.rc i found this line:
"#backlight
chown system system /sys/class/backlight/rk28_bl/brightness"
so i'll try change it to:
#backlight
chmod 0777 /sys/class/backlight/rk30_bl/brightness"
-------------------------------------------
F**k yeah! I fixed the permissions. Now it works perfectly on every boot . Now boot.img must me flashed with RKAndroidTool v1.35.
I hope I fixed it right the brightness:
Can anyone please test it?
