[APP] LG 2X/Black Notifications

Hmm thanks for the explanation. I had a feeling SuperUser wasn't working very well too. Here is the v1 for people who changed to SuperSu. (I removed it thinking it wouldn't work.)

I have just tried it on the new CM10 build, and my version works fine with the ordinary superuser app there. There's something odd going on with superuser and the LG ICS builds.

I've been messing around trying to pin down the superuser bug. A couple of observations:

canWrite() on the brightness file initially returns False, even though the correct permissions have been set and the file is writeable by the application. This happens with both superuser and SuperSU. On CM10 roms, it initially returns the correct value. I have a feeling that if I can fix this bug, everything will work fine again.

With superuser, permission is granted and the chmod works, but the process does not close (bug in superuser I think).

it works! i had to manually modify /sys/devices/platform/star_led/leds/star_led/brightness permissions, the app itself doesn't ask for su permissions and therefore is not checking brightness perms (?)

thanks for the hints guys

I tried this, I set the brightness to 7, but it worked until the lights went out for the first time, then the brightness value returned to 25.
Why?

I have Official ICS V30a.

Which version did you use? (my version v1 or v2, or rmein's apk?)
Do you mean the application works but the first time, the brightness' value is 7, and next time 25? Or it works only the first time?
Can you check the file's permission is rw rw rw ?

I use v2 and the file permission is rw rw rw.

I open the file "btightness" with any text editor and i see that the default value is 25. than i set the value to 7 and save the file. The brigness level remains to 7 until the touch key lights turns off for the first time. When i touch the screen again the lights are brighter and if i open the file, the value is reset to 25.
But if I go to Settings => Display => Brightness => Front key light, and turn it off, the brightness value remains at 7 but the lights remain lit all the time, even in deep sleep.
It has to do with the kernel that automatically overwrites the value, and when i disable them from settings, the kernel already consider them off even if the LED Notification use them?
