Turn off buttons' backlight on HTC Desire

I find it annoying when reading ebooks so I decided to turn it off. The setting is located at: sys/class/leds/button-backlight/brightness. Unfortunately the program I'm using, root explorer, won't let me access this value although I have rooted my phone. Is there any editor program for android like regedit for windows or is there any other way to do this?
Thank you!

I managed to "open as text" (cannot be edited) and the value is 255. I want to change it to 0. Anybody????

I would like this aswell for when im reading.
Thanks

here is a way to do:
load the program called "Gscript Lite" from the market
create a new script called
"keybacklight_off"
type in
echo 0 > sys/devices/platform/leds-microp/leds/button-backlight/brightness
create a new script called
"keybacklight_onn"
type in
echo 1 > sys/devices/platform/leds-microp/leds/button-backlight/brightness
klick on you homescreen klick on "links" (i have a german Phone dont know how it's called on your Phone)
click on Gscript Lite and select you script

I have a problem. The script definitely works, but as soon as I open an ebook with aldiko reader the backlight turns on again and the same thing happens when I power the screen off and then back on. Is there a way to permanently turn off the backlight?

Thanks for your idea! Why not post it in dev forum, so they can build it in new roms

Thank you. You have my "permission" to do so if you want.

matter to me that when I'm going to watch a video again I turn back, there is some way to turn them off permanently?
thanks

Hi, is there a permanent fix now?
Every time my screen turns off the backlight comes back on

I think you've misunderstood me (or rather, I just said it wrong ): The lights turn back on when the display has been off... they're not on while the display is off, but if I turn the display off and back on again, they're back on.
Maybe it's because the Desire doesn't have read/write access to the system files?

Is there a way to turn off the HOME, MENU, BACK, SEARCH button light permenatly? I just want the screen on and the buttons to remain off.
thanks

Yes, install "LEDs hack" from the market. Will turn off button lights but needs root.

Tried this app
It's doing its job but keeps annoying me with a warning "... has been granted superuser ..." every 10 seconds or so.
Uninstalled immediately !

Works great for me running Leedroid 2.2e. Check your superuser is up to date as per the initial screen.

Got it working without notifications now. Great app. I'll just keep an eye on the battery usage when the phone is on standby.

How to switch off your softkey backlight

I see a few people asking about this and I found this app that works on my HTC One X.
Screen Filter:
https://play.google.com/store/apps/details?id=com.haxor&hl=en
If you just want to switch the lights off, set the filter to 100% then un-tick the enable softkey back light. It works great when watching videos or using it as a nightstand clock.
Hope their wasn't a thread about his. I did a few searches and couldn't find anything, hope this helps a few people.

Does it save the preference after reboot? I use Adjbrightness and after rebooting I have to load the app up again.

I will have a look but I think you have to reopen it.

I had a test now and it doesn't start on boot. But when you start the app after a boot it then knows what your last settings were. Hope that helps.

K, when I have the time I was thinking of writing my own app that does this.

If u put the app (screenfilter) in some autostart program it will work fine, if u dont wanna enable it manually.

That is a great idea, I was wondering if there was an app like that I will have a look and see how well that works. But it's really nice to disable those lights, gives the phone a really neat appearance.

I did this on my previous device (xperia u, to get rid of the annoying LED-bar )

NOTE:
*** If you accidentally make your screen go BLACK ***
1. Pull your battery
2. Uninstall the app to reset your bad brightness setting
3. Reinstall the app and use it normally again"

Don't worry if you hold down the power button for a couple seconds it simulates a battery pull. Then when you start up, provided you don't have it on a autostart app you can then go in and change the settings. Also if you do set the brightness too low it gives you 10 seconds to approve it or it will just revert your settings. If that makes sense.

Make a new file, call it 99KeyOff.sh and put this in it:
#!/system/bin/sh
# ========================================
# init.d script for key light off. ONE X.
#BACKFROMTHE[/QUOTE]STORM
# ========================================
#disable Key Backlight
echo begin set Key Backlight - KB
echo KB - set permissions rw
chmod 0666 /sys/class/leds/button-backlight/brightness
echo KB - set Key Backlight 0
echo "0" > /sys/class/leds/button-backlight/brightness
echo KB - set permissions ro
chmod 0444 /sys/class/leds/button-backlight/brightness
echo KB - done!
Put it in the init.d folder or run it manually in a terminal emulator or script manager.

Unfortunately that doesn't work on the Maximus ROM. I think it's because the rootfs mounts read only. I tried adding a remount line to the top but nothing happened.

[Q] Tester for Capacitive Button Brightness App

Hi One X community! I'm from the AT&T One X world, so I don't really belong here However, I wrote a little app for the evita/snapdragon One X that changes the brightness of the capacitive buttons (back, home, recent tasks) and I'm curious to see if it also works on your endeavoru/tegra3 One X. Would anyone be willing to test it out and report back in this thread? Although the app requires root permissions, I cannot imagine it doing any damage to your device should it not work. That being said... anything is possible... you have been warned
If you don't mind testing it out, there are 2 ways to do it:
Load the APK file for the application and run it
Run a command as root
Load the APK file for the application
If you are willing to load the app, the APK is available here: http://forum.xda-developers.com/showthread.php?t=1912216. After loading the APK, just launch the app "Capacitive Buttons Brightness" from the launcher and press one of the 3 buttons in the UI. If the capacitive button brightness changes, then the app works.
Run a command as root
Run the following command from a root shell:
echo 0 > /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/button-backlight/currents
This should shut off the button backlight. Using 1 and 2 instead of 0 should make the button backlight dim and full, respectively. These are the commands ultimately issued by the app.
Other Ideas
If this method of setting the button brightness doesn't work, would you happen to know the command to issue that does work? If you do, I could incorporate that command into my app, and have it choose the right command based on the current device.
Thanks in advance for your help!

Hi there, didnt try your app.
But here at endevour we do stuff differently
either with some kernel hacks - never tried them
apps like screenfilter or adjbrightness and its child.
or :
SENSE: editing framework-res
CM10(not sure this would work on sense):
echo 0 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness
chmod 444 because as soon as you go screenoff it changes to default value, same as reboot.
that path you posted I couldn't find it in my installation.
echo 0 > /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8xxx-led/leds/button-backlight/currents

Thanks PAGOT for the information. So if I understand you correctly, running these 2 commands will turn off the capacitive buttons backlight:
echo 0 > /sys/class/leds/button-backlight/brightness
chmod 444 /sys/class/leds/button-backlight/brightness
But you're saying these two command only work on CM, and not Sense-based ROMs?

I do not know if they work on Sense roms, I didn't try it there. On sense I edited framework-res which doesn't work for sure on CM.
Dont know the other way around . Someone with a sense rom and rooted would have to test it. Right now I am not near a device like that to test.

In an attempt to get this app working on the HTC One X+ (evitareul) I believe I also got it to work on the international One X (endeavoru). Since they both use the Tegra3 chipset the changes that made it work on the One X+ should make it also work on the International One X.
Could someone load the attached app and let me know if it sets the capacitive button brightness? If it does, then I will post an "official" version into the Play Store asap. Thanks!

Confirmed working on international one x running cm10.
The half brightness doesn't work though. When enabled brightness goes down for a split second and then back to full brightness. Nice little app.

Awesome. Thanks for your response! It was the same thing on the One X+ where "dim" and "bright" were exactly the same. On the North American One X (Evita) the "dim" setting is actually slightly dimmer than "bright". I will get this app fixed up and published as soon as possible. I will also start a thread in the apps/themes aection once that is done.

A widget would be a nice addition.

I've created one (hopefully) last test version of the app. This one only shows buttons for "bright" and "off"; the button for "dim" is not shown on the International One X since "bright" and "dim" have the same effective brightness.
Could someone do a quick test with the attached app? Just press the "bright" and "off" buttons each a few times and ensure that the capacitive button backlight turns on or off, as expected. Also, double-check that the correct device name ("HTC One X (endeavoru)") is displayed at the bottom of the "About" screen. Thanks!
Version 5 of the test app is attached.

An official version of the app that supports the International One X (endeavoru) has now been published. See http://forum.xda-developers.com/showthread.php?t=2033973

Works ok and the name is displayed correctly too.

[PRO]Toggle script help

My keyboard backlight trigger stopped working so i have no backlight when the keyboard is opened.
I was hoping to write a script to toggle the backlight using a spare hardware key on the keyboard (368, that silly search/browser key below the enter key).
I have written 2 scripts to turn it on and off which were really simple (and work :victory but a toggle script looks a lot harder.
OFF
Code:
#!/system/bin/sh
echo "0">/sys/class/leds/keyboard-backlight/brightness
ON
Code:
#!/system/bin/sh
echo "255">/sys/class/leds/keyboard-backlight/brightness
Can anyone help me with this, i suspect it would be pretty simple for someone familiar with scripts.
DId i mention i know nothing about writing scripts...

Code:
#!/system/bin/sh
state=`cat /sys/class/leds/keyboard-backlight/brightness`
if [ "$state" == 0 ]; then
echo "255" > /sys/class/leds/keyboard-backlight/brightness
else
echo "0" > /sys/class/leds/keyboard-backlight/brightness

How can I execute that script with the hardware key (search/browser)?

Any news about that ?

Yyyeeeah...
I wish there was more news, but I guess not...
How hard could it really be (for you awesome people who know how to do everything)?
I mean, I run the same (almost) ROM on both my xmp and xp, yet on xp there's no HW-keyboard backlight when clearly on xmp it's no problem.
I know the phone is outdated now to say the least, but seeing as how there's such a dedicated group of users who prefer to have a hardware keyboard, shouldn't there be at least one programmer willing to put a few hrs in?
Please, please, pretty please, please with ice cream and cherries ontop-- uuuh AND WHIPPED CREAM TOO! yum... -what was I talking about...?

Control your AOD (LED alternative - Automate flow)

Hi all,
I am also missing a notification LED for incoming messages et al.
Well, the following might be of interest for some of you. Let me explain: I took a closer look at Automate and the flows provided by the user community there. Unfortunately all the flows for controlling the AOD there do support Samsung and LG devices only. By chance I stumbled across the correct name for the Huawei-specific variable that needs to be triggered. So, I took a working flow for LG, simply replaced the variable's name and voila, a working flow, without the need for root or something.
And it works like this: each time an incomming message (or something similar) triggers a notification, the stock AOD gets switched on, showing you the usual clock and notification icon. As soon as you are disabling the notification (by reading the message etc. pp.) the AOD gets switched off again. This works quite well, saves some battery (compared to having AOD constantly on), and you can clearly see when a new message arrives. I also didn't need to put Automate in the battery white list, it simply works as intended.
The necessary steps to get this working are as follows:
Install Automate from play store
Install the Automate extensions "network permissions", "settings permissions" and "superuser permissions" (the latter does not need root for granting the permissions indeed)
Enable "superuser permissions" via adb:
Code:
adb shell pm grant com.llamalab.automate.ext.superuser android.permission.WRITE_SECURE_SETTINGS
Switch off the AOD functionality in your devices settings
Download the (zipped) flow I have attached to this post and install it
Start the flow and grant the permissions you are asked for
If you use flow v01 switch off the logging of that flow, there are tons of data generated while the device is plugged in via USB, flow v02 works fine with loggin enabled
Enable "Automate" in Settings -> Accessibility features -> Accessibility -> Downloaded Services
I have been running this solution since late November. For me it runs smoothly, stable and battery friendly. Maybe it's also helpful for some of you. Just let me know when you have questions.
Disclaimer: I have published the flow on 25th November at android-hilfe.de and in the Automate community only recently.
Cheers.
Update:
@RoteDose has been so kind and had a closer look at the old flow and completely reworked the power charging check, so there's no log flooding anymore. So he created a v02, that I have attached here now. Thanks a bunch for your support, mate!
To do: research for AOD icons to be refreshed after disabling the notification
- Found a list of Huawei specific settings here.
- And you can list the settings by
Code:
adb shell settings list system|global|secure

You can download to your phone the file "Huawei AOD switch.zip" I attached and unpack it to a path of your choice. In the Automate app you can import the unpacked "*.flo" file through the dots menu on the top right. You are then able to give permissions, switch logging and start/stop the flow.
Hope this helps. Just let me know. Cheers.

Is there anything else to do after the upload? Unfortunately, it doesn't work for me. I get a notification and nothing happens. But when I turn on the screen and lock the AOD shows. But that's not how it's supposed to work.

Its not working o my P30, Emui 10. I followed instruction everything allowed, AOD stock deactivated, but nothing......Automate works fine, flow is active, but...… What could be wrong......

First of all, thank you for this solution.
But I have a little problem. I don't know why, but for me doesn't work :/
AOD switched off -> started the flow (granted all the permissions) -> lock the screen -> i got a message (the phone vibrated), but the AOD doesn't switch on -> unlock the phone, just to the home screen (doesn't read the message) and lock again -> and now the AOD is switched on

The problem is solved.
Just need to enable this:
Settings -> Accessibility features -> Accessibility -> scroll down and enable Automate

Let's stop, switch on logging and restart the flow. Try enabling Automate in "Downloaded Services" as @razer91 described below your post. Maybe the log info will then help you finding out what goes wrong. Just let me know.

I don't think so. At least here it's all fine. Automate is not even in the battery saver white list, and going to sleep perfectly. Also, I detected no CPU wakelocks.

Yes, I checked too. The consumption of battery by Automata is minor.
