[MOD]Keyboard backlight toggle - LG Optimus 3D

I have tried to use some apps to turn off the backlight permanently but not work for my O3D.
So I tried an odd way to do it.
I tried to forced brightness value to 0 by using
Code:
echo 0 > /sys/class/leds/keyboard-backlight/brightness
chmod 444 /sys/class/leds/keyboard-backlight/brightness
Running this script should permanently kill off your keyboard LED. you can use
Code:
echo 1 > /sys/class/leds/keyboard-backlight/brightness
chmod 444 /sys/class/leds/keyboard-backlight/brightness
to turn on the LED or use:
Code:
chmod 664 /sys/class/leds/keyboard-backlight/brightness
to restore system automatic operation
I have written a simple apk file for u who dont have gscript.
the app just run the script above, you can always run the script on gscript or any terminal emulator you want (needs su)
Bug:
This runs perfect on my O3D now with Acurarom, but it sill have some problem with CM7-SF ROMs. Anybody knows what is the problem here?
For those who found the script useless, you might try to add two lines after turning on/off
Code:
chown 0 /sys/class/leds/keyboard-backlight/brightness
chgrp 0 /sys/class/leds/keyboard-backlight/brightness
and make sure add these two lines before the restore script
Code:
chown 1000 /sys/class/leds/keyboard-backlight/brightness
chgrp 1001 /sys/class/leds/keyboard-backlight/brightness
These two codes may prevent changing the led setting back to "rw" from some other apk with root access

HElP
I have the same problem but the question is how cpmment scripts with which tool is my first time I do this kind of things. Sorry for my english

Excuse me, where I post these scripts in O3D?

I have made an .apk file for anybody have trouble running the script

Thanks a lot for that apk. I've been looking for a way to turn the buttons backlight off n this works perfectly on 2.3.5. Thanks again!

Thanks for APK!

Is there any option to set the backlight on permanently only when the screen is on, and to dim it a bit?
Nice app btw.

I knew a way to do that but it won't be as easy as this one.
And for dimming the max backlight might require some mod in the boot.img which i am not familiar.
I will see what I can do
After all, this app only works with some devices on some ROMs. There's an app in the market that can do the job. If your devices made no response to those apps, you can try this method. (which is fairly unconventional)

would it be possible to make this script run at boot? (Such as init.d scripts), i've tried directly adding it to init.rc but it doesn't seem to work (System rewrites it the on boot, even without write permissions).
(Not with a script app such as Rom Toolbox/Script manager)

Here's the app that keeps the led lights on.

The app seems not working on my o3d.
BTW if you only want to keep the leds on while screen on and dim it, a modification from kernel or a background services might be needed.
I invent this method basically try to get rid of the services

It might be possible, but I don't know how to do it.. :-( ~~
at least not using "init.rc"

Thank you this app works for my htc chacha running superOSR rom based on CM 7 but only in turning off and can't turn it on again

Problem
Ok, i have tried the solution here, but my brightness file is here:
\sys\class\backlight\keypad-led\brightness
When i set it to 0, the lights turn off, and after that i change the file permissons to 444 with chmod.
But when i turn off screen and turn on again (stand by mode) the keypad lights turn on again, and when i go to edit the brightness file again, it shows the value 255.
Any sollutions??

Collin_ph Battery Tweak for Darch Froyo Roms

LAST UPDATE to this thread.
RC1 of Collin_ph battery tweak has been released.
Due to several changes, etc.. I'm starting a new thread here: http://forum.xda-developers.com/showthread.php?t=762283
Newest!
UPDATE - Beta 10 released 08/16/2010
Sorry about 2 updates really quick-- this latest release was to address 2 bugs that cropped up.
Description: Battery tweak is a collection of settings that enable the hero to optimize battery lifetime. I get 35+ hours on my hero with the tweak installed with the normal 691mhz settings. When on battery power, the cpu is gradually lowered (configurable) as the battery drains, and when put on power, the cpu is put into high performance mode. Most settings are configurable.
Beta 6 includes an optional LED fix if your charging LED is hanging, and some optional performance tweaks to the cfs scheduler. For more information see the documentation linked below.
Simply download the tweak and flash.
Reboot and under adb shell run batt-cfg
Note: Make sure you are root first by running su if you are going to run batt-cfg through terminal.
You may change the settings at any time by running batt-cfg again and settings will take effect without rebooting.
New verison as of 08/16
http://www.primoweb.com/froyo/collin_ph_battery_tweak_v3_beta10.zip
Documentation (Updated for Beta 10):
http://www.primoweb.com/froyo/battery_tweak_v3.html
This tweak will conflict with setCPU and OCWidget, so please disable them.
Can I say it again. Don't use set CPU, or OCWidget. You don't need them with this tweak. If you want to customize your CPU, simply run the customize utility in batt-cfg -- you can set your min/max clock speeds there. Thanks!
Feature list:
Customizable Battery Tweak with 2 presets
LED Fix for charging LEDs that are stuck on
Experimental CFS (completely fair scheduler) performance tweaks
Audio quality fix for froyo (disables stagefright)
Disk tweaks (mounts all mount points noatime,nodiratime)
Probably more I'm missing.
Edit:
If you want to try this tweak in another rom, your rom will need a /system/etc/init.local.rc file-- that's where the service is started.
Additionally, it won't do much good unless it's on a clockable kernel.
There are other prerequisites such as sh existing in /system/bin but generally speaking if it starts up, it should work. If your rom has no /system/etc/init.local.rc, you can add the file and "import" it (I believe), within the init.rc of the boot image, but it'll require a little work.

It should work with any .29 kernel that's has the same structuring as toasts/darchs, so theoreticaly, it'll work with any ROM really.
Can this be done if I'm using the darch overclock undervolt kernel for Fresh 2. 3. 3? The reason I'm asking is because my battery life is already good with darch's kernel but if I can flash this on top of what I'm using that would be great.

Only way to find out, try it.
Only problem is that I have no idea how to config the settings after setting this up. The instructions say to go back into the shell and configure the battery settings. Guess I will have to wait until someone who knows what they're doing tries. I don't have any skills at working within shell and wouldn't know what coding to write.

[Script] Darkness in the dark hours

hi everyone
I present to you:
Darkness in the dark hours​
this is a pack of:
- a script I made
- Gscript lite
- Screen filter(optional, but recommended)
I strongly recommend to you to read the whole post and only then apply my script!
A lot of users tried to find a way to do this, so I polished my script I used for Eternity to make it universal(hopefully )
this script made to work with rooted 2.1+ firmwares and busybox properly installed.
1. Install Gscript lite
2. To make this script revertable on the newer brand of kernels, you will need to add one line to hw_config.sh (because I just don't trust init.d scripts)
run this from adb or any terminal emulator from phone as superuser
Code:
echo "\n\n\nrm /data/noled_tmp_reverse.prop" >> /system/etc/hw_config.sh
3. in Gscript choose Add a script and name it whatever you want(e.g. NOLed) and paste these lines in it
Code:
#! /system/bin/busybox sh
# "turn off keyboard and notification LEDs" for ANY android firmware
# this script needs su access
# made by Adolf1994
# thanks for the help diimaan
# maybe final version - revertable
# requires hw_config.sh modification to be properly revertable
DIR=$(cd /sys && find | grep brightness | cut -c 3- | cut -d : -f 1 | head -n 1)
LED=/sys/$DIR
LED1=$LED:rgb1:red/brightness
LED2=$LED:rgb1:green/brightness
LED3=$LED:rgb1:blue/brightness
LED4=$LED:sled/brightness
if [ -s /data/noled_tmp_reverse.prop ]; then
chmod 00644 $LED1
chmod 00644 $LED2
chmod 00644 $LED3
chmod 00644 $LED4
rm /data/noled_tmp_reverse.prop
else
echo 0 > $LED1
echo 0 > $LED2
echo 0 > $LED3
echo 0 > $LED4
chmod 00444 $LED1
chmod 00444 $LED2
chmod 00444 $LED3
chmod 00444 $LED4
echo 1 > /data/noled_tmp_reverse.prop
fi
exit
4. tap on "Needs SU" then save
5. run the script and enjoy surfing at night without the annoying hw leds
(most likely you WILL get stderrs on 2.2+, but it's normal)
Note: if you get EMPTY stderrs, that's no problem. BUT if something is shown next to the stderr, like permission denied, then please report
optional. install Screen filter from market: https://market.android.com/details?id=com.haxor&feature=search_result
This is only for 2.1 and/or 2.2. On 2.3 I experienced a problem that's I couldn't press install in package installer activity. I nearly reinstalled the whole thing. You've been warned!
Night is over? Just run the script again and wait till the LEDs light up.
If You Don't Like LEDs At All, This Pretty Line Will Disable Them At Startup
http://forum.xda-developers.com/showpost.php?p=17514012&postcount=27
Q: Why modifying hw_config.sh?
A: Because if you reboot your phone while the leds are off, there will remain a file that normally indicates how the script should act upon running it. That one particular file should not present after boot.
Q: I'm on Wolfbreak's ROM. Won't that mess tweaks up?
A: In no way. Impossible. Unless you didn't follow steps properly.
hope you like it
and don't forget to press thanks button
can I use script manager to run this at boot?
I think it'd be fine

from gscript I get a bunch of stderrs, too. however, from a terminal emulator it runs fine, so no problem.
It's the most noticeable if the phone is on the charger, because you will see that the led suddenly switches off.
you can revert the script back with a simple reboot.
Sorry for being a noob, but what does this do? :$

any new experiments with sd card mounting?
There was some interesting posts by one shaun in link2sd thread! he's using x10! somehow he managed to find more free space in /system than in /data!
so no need of an extra partition, you can just run the script to mount the /system as rw on boot and then link the link2sd mount point to it! I sent a PM to him about how is it working! let's see...

Should explain how to do it, just need to add commands to a start up script that is editable on your phone, that runs before the GUI is started. Dunno how I would create a universal script as you will need to edit diff files on diff phones.

[Q] Keyboard Dropping/Missing Keystrokes?

Since I've gotten my Sidekick, I've noticed on most ROMs a horrible tendency to not register key-presses on the physical keyboard. There was one ROM early on that didn't do this (or very little) and one of the versions of RAGE was very good. I'm running GOV3.2 Bulky right now and it's not horrible, but it's noticeable. Does anyone have an idea of what might cause this? Thanks.

I wonder what the issue is that's causing it to show up on custom ROMs. Though, I've had it on the stock ROMs as well.
Have you tried this version of the kernel? Along with the removal of the keystroke logger, it also contains a patch that allows you to lower the keystroke timer delays... If you are experiencing dropped keystrokes, this could help, as the patch was designed for tht very issue.

Thank you!!!!!!!! I went ahead and dug into that thread. I do have that kernel already on my phone. I looked at the thread linked in that thread that gives a patch to adjust the timer delay and column delay in the kernel. HOWEVER, I'm not knowledgeable enough to apply that patch to my phone as it's given. Elsewhere in that thread, someone gave the commands to edit the settings manually through a terminal which I did through Android Commander on my PC and it worked wonders! Being the suspicious type, I guessed that the settings might not keep after a reboot. Unfortunately, that is the case and I had to reapply the settings after my phone finished restarting. So, I'll have to play with this a bit more to get it to keep, but thank you for showing me this!
You're welcome! That patch was made just for this issue. And yeah, it doesn't stick after a reboot, so we could either compile the kernel with chosen settings added in, or make a simple init.d script. I never did either one lol, was too lazy to try editing and building the kernel from source, and was on the stock ROM so I thought maybe it had no init.d support. You could probably create a file with those same commands used in Terminal, and throw it in your init.d folder to change the settings at boot.

I set my column delay to 30 and my timer delay to 1 and it now feels like I'm typing on a Sidekick again! I wouldn't know how to correctly compile the kernel myself with these settings changed. So, are there any devs out there willing to make a zip that can be flashed in CWM so these settings will become permanent?

I've noticed this problem and thought it was just me :$

To those interested in the commands I used to fix the keyboard, see below. If you reboot your phone, these settings will go away and you will need to input these commands again. For a permanent fix, someone will need to add them to a kernel that can be flashed. To use these commands, your phone must be rooted. I've successfully used Android Commander to enter these commands from my PC while my phone is connected via USB.
The current timer delay may be read with:
cat /sys/devices/platform/s3c-keypad/timer_delay
The default is 5 if I remember correctly.
A new timer delay may be set with:
echo 1 > /sys/devices/platform/s3c-keypad/timer_delay
The default 300 µs column delay value may be read with:
cat /sys/devices/platform/s3c-keypad/column_delay
A new delay may be set with:
echo 30 > /sys/devices/platform/s3c-keypad/column_delay
In either command, you may experiment with different values by changing the 1 or the 30 in either command to what you want. I believe the lowest is 1 and the max is 256 for the timer delay. If you damage your phone running these commands, that's on you. I'm just telling you what I did and feel worked for me. YMMV. Also, if you don't want to connect your rooted phone to your PC and want to use Terminal Emulator from the Play store, that will work too. You need to enter 'su' prior to running the above commands and grant the terminal super user permissions for the commands to take.

You are very welcome! All done, BTW. Posting my updates now.
Permanent Fix(Manual way)
Taking the timer_delay and column_delay tricks shown above...I was able to make an init.d script(pretty easy, tbh) but don't feel it merits an update.zip since it's so easy. What I did was:
1. go to /etc/init.d
2. find the last script(In GOV3.3 it's 18complete) and rename it - adding one to the sequence(In my case I renamed it to 19complete)
3. make a new file name 18keyboardfix(The number depends on your rom, really...like if you renamed the above file to some thing like 33complete, you'd call this 32keyboardfix. Easy? right?)
4. Open the file you just created and put:
Code:
!#/system/bin/sh
echo 1 > /sys/devices/platform/s3c-keypad/timer_delay
echo 30 > /sys/devices/platform/s3c-keypad/column_delay
5. Set the permissions to rwxr-xr-x or whatever the numeric equivalent is. (0755, iirc)
6. Reboot
7. (Optional) Recheck the values with the following commands:
Code:
cat /sys/devices/platform/s3c-keypad/timer_delay
Code:
cat /sys/devices/platform/s3c-keypad/column_delay
I take no credit for this fix. Really, it was all ged92781 for providing the commands. All I did was find a way to make it permanent(Well, it's just reset when the devices is turned off and the init.d scripts set it back to you desired values, but that's debatable on whether it's permanent or not...either way...it works and is a simple fix)

Idk, honestly. Try and see if your script works first, if not, then use the one I made using the commands ged92781 provided. Now...to find a way to fix the spaztic touch screen...that'll be tricky.

[GOVERNOR][2.6.39.4] Hotplug for Nvidia Tegra

Hello again xda, today I want to present something tiny, but nontheless important (in my view) for our old TF101 ...
The first working HOTPLUG governor for this device!
Q: What the hell is 'hotplug' ?
Hotplug Governor:
The “hotplug” governor scales CPU frequency based on load, similar to
“ondemand”. It scales up to the highest frequency when “up_threshold”
is crossed and scales down one frequency at a time when “down_threshold”
is crossed. Unlike those governors, target frequencies are determined
by directly accessing the CPUfreq frequency table, instead of taking
some percentage of maximum available frequency.
The key difference in the “hotplug” governor is that it will disable
auxillary CPUs when the system is very idle, and enable them again once
the system becomes busy. This is achieved by averaging load over
multiple sampling periods; if CPUs were online or offlined based on a
single sampling period then thrashing will occur.

As you can see, hotplug is able to deliver you the fastest experience and the most fps in game (kernel independant), but it also allows for completely switching off one core to save battery life. In my testings, that worked very well. I also found out, that with this governor, my TF is deep-sleeping like a baby. No governor around here (not even smartassv2 ... could deliver me this performance while maintaining a decent battery life).
Tested on EOS 4.2.1 with EOS4 kernel
But try out yourself:
NOTE: This works on any 2.X kernel available (my Harmony series, ELiTE series, KatKernel series, or any other kernel except my divemaster)
Code:
1) Download a terminal emulator (if you don't have one already)
2) Download the .ko module from [URL="https://dl.dropbox.com/u/31119007/xda/hotplug-tegra-2/cpufreq_hotplug.ko"]here[/URL]
3) Remember the path you saved the module to (or preferably move it into /system/lib/modules)
4) su
5) insmod path-to-module/cpufreq_hotplug.ko
6) Switch to 'hotplug' governor with your favourite tool.
If you were too lazy to read my instructions, this is for you ..

As always, have fun, share, and report back!
​
I have followed the instructions, do I have to run it every reboot or just this one off?
Nothing really happened when I ran it but I guess it just loads the module.
Cheers buddy
Must say thanks again for all the amazing work!

Good work! I was trying to do this same thing the cpusleeper app but couldnt get it to work. Definitely giving this a go.
Edit: installed fine but wont survive a reboot. Any fix for e this?

Got a reboot while browsing with stock browser for five minutes.

The only problem as 2 people discribe abovme is RR or Random Reboot.
Thats only problem.
sounds very promising i'll try it out and report if I get any RR's.
Getting error insmod: Can't open 'path-to-module/cpufreq_hotplug.ko'
Cd to my download folder which is where it is, am I doing something wrong?

Wow I derped that up, thx lol.
Was running fine at 1.2 decided to bump it up to 1.4 hit apply and it rebooted on me, is also didn't stick after reboot like others have said.
In here you may find how to make permanent the governor insmod.
Long story short is "add a script in /system/etc/init.d , it can be something like 91modules. . Add execution permission and it can contain the same code as before. Reboot and it should load your module at boot (be sure that the path to your module is right).
Also, you can do that in one line as root in a terminal. First, be sure that your /system is mounted as rw, not ro. If you don't know how to do that, as root, in a terminal, execute:
Code:
mount -o remount,rw /system
Then:
Code:
echo -e \#\!/system/bin/sh'\n'insmod [B]/path/to/module[/B]/cpufreq_hotplug.ko > /system/etc/init.d/91modules | chmod +x /system/etc/init.d/91modules
"
It should load automatically next time you reboot.
I created the 91modules file and done the editing and file permission in ES File Manager, but the above instructions should work flawlessly.
Don't thank me for this. Thank MapleSyrup

Posts like this are keeping my work up and my releases coming.
People like you are the reason I am putting this much effort in this kinda old device .
For those who experience SOD/RR with hotplug and can confirm it's not related to anything else, please gimme a dsmg/ksmg (I recommend using 'Lumberjack' from the playstore (made by Chris Trotman, EOS founder).
*NO* logcat, that isn't any useful for me in this case ..
I do now have 2 days uptime with hotplug governor, not a single SOD/RR, pretty much usage (wifi on all the time, a little Riptide GP, web browsing, most of the time playing music) and still got 20% left with EOS4 kernel while achieving full performance while needed. This thing is deep-sleeping just perfectly.
I have placed the hotplug in the system this morning and my battery life still 99% im using it with dock and dono m8 but if theres any problem but seems my tf101 dont consume energy at all im starting to get scarry lol

I typed all this in and it wont survive uve a reboot. I placed the module in /system/lib/modules and typed that. When i see the | is that a new line or all one line?
Sent from my Transformer TF101 using xda premium
You can make that code in 2 commands, 1st is all before the | and 2nd the command after the |.
In order to work your final 91modules should look like
Code:
#!/system/bin/sh
insmod /system/lib/modules/cpufreq_hotplug.ko
In order to test if it's working you cat try to run it from the terminal (it may need "su" before)
Code:
./system/etc/init.d/91modules
If it's not complaining about not being executable, you may test to see if it's loaded with "lsmod".
If it's loaded it surely will survive the reboot.
I hope that helps you.
Looks like it created the 91modules file in init.d but when i try to set permissions using chmod +x it says bad mode. Maybe thats why it isnt working, wrong permissions.
Sent from my Transformer TF101 using xda premium
Indeed the chmod +x command doesn't work.
You may use ES file explorer to set file permissions but also you need to allow it superuser access, mount /system as writable and "up to root" and mark execute and write to the user. At the end the file should have the following permissions: rwx r-- r--
Ill give that a try and see if that does it. Thanks!
thanks
Thanks RaymanFX, this is a great addition to our device.
Also thanks to all your work, you are keeping this device alive...

Minfree settings in CM12 Roms

As there are again and again discussions concerning the minfree settings in CM12 roms, I decided to open this thread. If a moderator thinks, this is the wrong place for this thread, just move it, to where it belongs.
Obviously, since the last builds of CM12, the settings for minfrees cause some trouble. After a clean install of any rom, the minfree settings in trickstermod and in fauxclock are completely empty. In fauxclock the settings for OOM (out of memory) Score as well. Some people entered them manually, but I'm afraid, this won't help.
To really solve this, you have to do the following steps: open your file explorer, go to sys/module/lowmemorykiller/parameters. There you will find 5 files. Two of them do not have correct permissions. The first one, called adj, is for the OOM Scores. The other one, called minfree, is, you won't guess it, for the minfrees. :fingers-crossed:
As you see, both of them have only write permissions, but no read permissions. So I guess, the system will ignore these settings completely. I checked this, using cool tool from play store, very nice tool to show for example the actual free ram in your status bar. And in deed, the ram went down to 25MB, after I had opened a handful apps, and then my phone stopped working. I only could do a reboot.
Now the solution, which is quite easy: change the permissions into rw-rw-rw (666), and maybe change the group under owners into root (I'm not sure, if this is necessary, but it does make no problems, so why not).
Et voilà - if you now open trickstermod or fauxclock again, you will see the preset parameters. As you can see also, the minfrees there are really high. In another thread, there have been suggested the following settings, which are a good standard:
trickstermod 48/60/72/84/96/120
fauxclock 12288/15360/18432/21504/24576/30720
Important: In fauxclock, the minfree settings are not made in MB. You have to enter the so called "pages" for minfrees, which I can't explain exactly, what this is. In general, if you want to change minfrees in fauxclock, just take the settings in MB, you want to, and multiply by 256. This will give you the correct values.
BTW I don't think, it's a good idea, to change the OOM Scores, as long as you do not know exactly, what you're doing.
So, hopefully I could help a bit and clear some things up. But the final question to the CM devs remains:
is this a bug or is this a feature?
With me, those files were already chmod 666, owner root. I use latest liquidsmooth rom. What i did, prior reading your post, was that i set minfree in trickster, from my presets, than immedatly switched to faux, parameters were there, pressed apply, switched set on boot and rebooted. After that minfree r sticking in faux and trickster. Guess that my actions leaded to what you have described. Anyway, your way is much more convinient - at least one app less to use
I don't get it... The directory you mentioned is empty on my one s as well as on my nexus 10 both with cm12.
However my settings stick since I use fauxclock.
One more thing I don't get is in fauxclock. It says "kilobyte" explicitly in the minfree settings although you said (and it stems to be) this strange pages value....

You have to use your file manager with root permissions. Depending on which file manager you use, this can be done differently. The inbuilt CM12 file manager can be given root permissions in settings, in Root explorer for example you have to mount the directory as r/w.
An yes, you are right, fauxclock says, the settings are in kilobyte, but this is not correct. If you succeed to open the minfree file with your file manager, you will find there exactly the values, you have entered in fauxclock.
Damnit, you're right. Solid explorer doesn't show the content of the directory.... I use it a long time and always had the feeling solid explorer shows me all files...
Cm file manager works, thanks!

It does work with solid explorer as well. The point is, there is no option, to set root permissions manually in solid explorer. So the trick is to create a situation, where solid explorer will ask for root access. For example: long press any folder in your system root, tap properties, tap change (attributes) and now press OK, without changing anything. You will be asked for root access.
Now everything should be fine!

For solid explorer, just try to open /data and it will ask for root permissions. I do it every time I flash my phone.
Thanks a lot man! I wasn't aware of the skewed minfree files. Was setting them in Trickster and wondering why the apps keep shutting down on me when multitasking. Great work

Uh yes obviously. However they were actually closing the instant i opened another app. Couldnt even keep two apps open at the same time, that was pretty bad.

Yes, I know what you mean. Was the same for me. Having better minfree settings that stick after a reboot helped but didn't solved the issue completely. But at least now phone is usable. I put my hopes in that Google patch they'll release with 5.0.3

Thanks for this thread, I changed the permission with "chmod 666" using adb shell, but after a reboot, the files were back to write-only mode, is it normal ? How do you make it permanent ?

If it's reverting, I guess the only way would be through an script that runs at boot time. But it's strange, the permissions should stick once set...

I used a file explorer with root permissions like root explorer or ES file explorer. My permissions are actually rw-rw-rw, both for adj and minfree file. I guess, this is 666? And they stick after a reboot. But honestly I am not quite sure, if I changed something else. IIRC, I might have changed the permissions for system/etc/init.d/90userinit to rwxr-xr-x. Maybe you want to check this, too.
Well, they don't stick because init.rc sets them to chmod 0220 on boot. That makes me wonder if maybe it was supposed to be like this? I wanted to change it but I don't want to screw anything up. There is a dedicated section for low memory killer in init.rc and only things there are chmod 0220 for those two files and chown for them - so basically the things that we are fixing in this thread. A bug or a feature?

Thanks for this hint! Indeed, this might be the other thing, that I had changed. In CM11 roms, the described permissions in init.rc are 664 - both for adj and minfree file. I am not quite sure, if this helps, but it's worth an attempt. You can change the permissions in init.rc to 644, reboot and see, if the permissions for adj and minfree are sticky now. I just did this ,and everything is fine -so you can try without risk, I guess. But I must say, I hadn't the problem before, that the permissions for adj and minfree were reset after reboot. Could be related to the changes in init.rc, but I am not sure.
A weird thing: I made a backup and tried anyway yesterday but after a reboot my init.rc restores itself to normal. I tried another time: Modified the values and saved. After reopening it's still there and it stays there but only until I reboot the phone. After reboot the permissions are not set correctly and init.rc restores itself to original state. Is there something I do not know about modifying init.rc? Because that is the first time I try to do something with it.
