Keyboard Backlight

[kauthor47]

A friend of mine has a Cliq that he was a bit unhappy with, using the stock software. I've taken him through the process of rooting and flashing a couple of roms, the latest one I installed for him is j_r0dd-mb200-v1.7.6. I've noticed that ever since giving him custom ROM's, his keyboard backlight hasn't worked at all, and I haven't really seen a definitive answer or fix for this. I tried to follow these directions:

I have written a very simple solution to the keyboard backlight issue:

prerequisites:
root access
busybox (possibly)

The trick is to read from the input device related to the keyboard and turn the light on when any key is pressed.
As the read call is blocking until any key is pressed there is no CPU consumption (and consequently no battery discharge due to the script itself).
you have to create a script called for sample backlight.sh and insert these instructions:

while [ 1 ]
do 
  cat /dev/input/event3|read -n 4
  echo "1"> /sys/class/leds/keyboard-backlight/brightness
  sleep 1
done

copy it on sdcard and try to launch it as root from a terminal emulator:

If you don't want the script has bound to the controlling terminal launch it with:

nohup bash /sdcard/backlight.sh > /dev/null &

now when you press any key on the keyboard it would light up!

leave a feedback please!

But to no avail. If anyone can shed some light on this little script, or perhaps give some more detailed instructions of how to run it (run it through terminal? press return key three times after typing in the command? etc) that would at least be a bit of a head start.

Thanks.

i have the same exact problem with my wifes cliq. I started flashing and the keyboard stopped. There was only 1 ROM that it worked on. I hope this works, but can u explain this in noob version. I know how to do some things, but i dont understand half of what u said

workkkk in my dext thks brooo

Did you follow the directions verbatim or improvise? I'm just wondering if I'm overlooking something or if it just isn't working on his Cliq.

i havent tried it yet, i just dont understand how to write a script and is the second option via terminal emulator?

[kauthor47]

My guess was to paste the code into a text document and rename it to be .sh instead of .txt, and execute it in the terminal using the commands given. But I may be wrong since it didn't work for me.

I've packed the script in a flasheable patch.

Requisite: rooted rom with init.d support (all the 2.1 rom except VwE series):

wow! I see that my script was successful!!
no importance if you launch throw terminal emulator or adb shell the last command.
But with the adlx patched version there is no need to use that command.

ok, you made a good thing to create a patched version of my script.
But the script produces some messages on the standard error (without any importance), this is the reason I used the redirection to /dev/null in the script launcher (nohup...).
As you inserted the script in /system/etc/init.d, it needs to test where the standard error messages go.

yeah good point :-D. The output should now go to logcat.

k. ill try this as soon as i re root the wifes cliq. Stupid me wanted the stock 2.1 so i reverted to stock, upgraded and now i lost root access or at least my recovery. And I come to find out i still cant update the stock 2.1 since her latest version is some ish thats not listed in the requirements

uhm.. I think the script needs #!/system/bin/sh on the top to work correctly in init.d..can you correct the patch?

no, im just created n load script code 1 via Gscript mode.apk

the script is correct now :-), have you set execution permission to it? As it is invoked throw the program run-parts, it requires execution permissions..

I've just checked, just in case, but both the script shebang and the script permission were already set correctly in the zip I published.

The patch is to be flashed! Not extracted and pushed manually :-D.
