Hi,
Looking for the web i found this tweaks for lg touch for nexus 4 ?
It will work with the lg optimus 4x HD (P880) ?
I have some issues with the touch accuracy..
Code:
####################################################################
# TOUCHSCREEN ACCURACY FILTER
####################################################################
if [ $TOUCH_TWEAK_EN = "y" ]
then
echo "Touch Control enable status *before* running the script"
cat /sys/devices/virtual/input/lge_touch/accuracy_filter_enable
#Turn on
echo "$touch_force_en" > /sys/devices/virtual/input/lge_touch/accuracy_filter_enable
#Adjust the params
echo 5 > /sys/devices/virtual/input/lge_touch/ignore_pressure_gap
echo 4 > /sys/devices/virtual/input/lge_touch/touch_max_count
echo 50 > /sys/devices/virtual/input/lge_touch/delta_max
echo 8 > /sys/devices/virtual/input/lge_touch/direction_count
echo 1 > /sys/devices/virtual/input/lge_touch/time_to_max_pressure
echo 55 > /sys/devices/virtual/input/lge_touch/max_pressure
echo "Touch Control enable status *after* running the script"
cat /sys/devices/virtual/input/lge_touch/accuracy_filter_enable
echo ""
fi # end of [ $TOUCH_TWEAK_EN = "y" ]

Thanks!!
Won't work as the echoed files aren't in the directory it's trying to change
I think with a little file path change/ file name change it would work but I'm not that much into it

Sorry for my weak English。
In order to improve the sound ,I write a script.
as below,the script doesn't work.
Can you tell me,what's wrong in the script?
sorry from my bad English!

These are different usb modes you can force from a adb shell (needs root)
This is just a fyi for information.

cdc_ether
Hi I am trying to connect a cdc_ether device into the LG Nexus5 usb port. I have cross compiled kernel for 3.4.0 hammerhead for this devices and enabled the cdc_ether module on it. But when I looked at the /sys/devices/virtual/android_usb/android0/f_cdc_ethernet/on, the f_cdc_ethernet directory doesnt exist. Does that mean the kernel was compiled wrong?
Can I use gasket to enable upsm at 5% ? I'm complete noob so will need talking through thanks

Thanks for reply but that means nothing to me?
No one with a basic guide
Do you have ROOT?
If not, you can"t auto turn on UPSM.
Yes I have root
@bandit250
you are still interested?
Yes please
First, Make a test.
Task:
1. Run shell [mark ROOT]
Command:
echo "2" > /sys/devices/virtual/mdnie/mdnie/accessibility
Push play
upsm should turn on.

I try, through the Kernel Adjutor, to set the minimum frequency of the big / little cores, but they are reset. If I understand correctly, this is due to the "System Modes" setting in the "Battery" section. The maximum frequency can be lowered and maintained, but the minimum is reset each time. Is there a way to stop this behavior?
Probably not. Your only option is to use a custom ROM I think.
Solved with script
