Hi guys. I have some init.d script that I use from previous kernel. Would appreciate it if someone can tell whether it'll work with this kernel.

One is for colour and gamma

#!/system/bin/sh

#Setting rgb
color_r=255
color_g=255
color_b=255
echo "$color_r $color_g $color_b" > /sys/devices/platform/kcal_ctrl.0/kcal
echo 1 > /sys/devices/platform/kcal_ctrl.0/kcal_ctrl

#Setting gamma
g_white=84 #Whitepoint, LG=0x72, GOOG=0x40,40,20 Low values=extreme whites, risk of blown out highlights
g_mids=42
g_black=118 #Blackpoint, LG=0x76, GOOG=0x76,76,74 Low values=cut out, banding in the shadows
g_unknown1=0
g_contrast=22 #Contrast, LG=0x00, GOOG=0x00,00,1F
g_brightness=6 #Brightness, LG=0x00, GOOG=0x00,00,10
g_saturation=74 #Saturation, LG=0x50, GOOG=0x30,30,50
g_greys=48
g_unknown2=2

#Tweak red gamma values here if needed
gr_white=`expr $g_white + 0`
gr_mids=`expr $g_mids + 0`
gr_black=`expr $g_black + 0`
gr_unknown1=`expr $g_unknown1 + 0`
gr_contrast=`expr $g_contrast + 0`
gr_brightness=`expr $g_brightness + 0`
gr_saturation=`expr $g_saturation + 0`
gr_greys=`expr $g_greys + 0`
gr_unknown2=`expr $g_unknown2 + 0`
gr_cksummotley=`expr $gr_white + $gr_mids + $gr_black + $gr_unknown1 + $gr_contrast + $gr_brightness + $gr_saturation + $gr_greys + $gr_unknown2`

#Tweak green gamma values here if needed
gg_white=`expr $g_white + 0`
gg_mids=`expr $g_mids + 0`
gg_black=`expr $g_black + 0`
gg_unknown1=`expr $g_unknown1 + 0`
gg_contrast=`expr $g_contrast + 0`
gg_brightness=`expr $g_brightness + 0`
gg_saturation=`expr $g_saturation + 1`
gg_greys=`expr $g_greys + 0`
gg_unknown2=`expr $g_unknown2 + 0`
gg_cksummotley=`expr $gg_white + $gg_mids + $gg_black + $gg_unknown1 + $gg_contrast + $gg_brightness + $gg_saturation + $gg_greys + $gg_unknown2`

#Tweak blue gamma values here if needed
gb_white=`expr $g_white + 0`
gb_mids=`expr $g_mids + 0`
gb_black=`expr $g_black + 0`
gb_unknown1=`expr $g_unknown1 + 0`
gb_contrast=`expr $g_contrast + 0`
gb_brightness=`expr $g_brightness + 0`
gb_saturation=`expr $g_saturation + 1`
gb_greys=`expr $g_greys + 0`
gb_unknown2=`expr $g_unknown2 + 0`
gb_cksummotley=`expr $gb_white + $gb_mids + $gb_black + $gb_unknown1 + $gb_contrast + $gb_brightness + $gb_saturation + $gb_greys + $gb_unknown2`

echo "$gr_cksummotley $gr_white $gr_mids $gr_black $gr_unknown1 $gr_contrast $gr_brightness $gr_saturation $gr_greys $gr_unknown2" > /sys/devices/platform/mipi_lgit.1537/kgamma_red

# Show the current configuration and the checksum
echo "Verify that the values are written correctly..\n"
echo "RGB values:"
cat /sys/devices/platform/kcal_ctrl.0/kcal
echo "\nRed gamma values:"
cat /sys/devices/platform/mipi_lgit.1537/kgamma_red
echo "\nGreen gamma values:"
cat /sys/devices/platform/mipi_lgit.1537/kgamma_green
echo "\nBlue gamma values:"
cat /sys/devices/platform/mipi_lgit.1537/kgamma_blue
echo ""

Another one is for stock f sync behaviour, ie F sync always on.

#!/system/bin/sh
#stock f sync settings
#place in init.d or userinit.d with the correct permission, rwxr-xr-x for it to be enabled on boot.
#delete this file to disable it.

echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled
[/HIDE]

Thanks guys!
