I dont think you understand, you cant change init.x3.rc it is part of kernel ramdisk. You can only unpack boot.img then change file and then repack and flash it. So what i am asking you is to go to folder on the path, you will there see file enable than change it from 1 to 0 and than back to 1. No rebooting.
[LG Optimus 4X HD] Zhus06:
Okay done that, when i have set it to 0 all cores fired up (as they probably should) and all clocks worked (i think) now when its back to 1 its same as before, actually it's kinda worse, in 10mins the screen was off it had 4 seconds offline time on CPU0 and 6m on 475Mhz. 1 minute on 1500Mhz (the time my screen was on),

what to do? 51mhz and 102 are under 2seconds.. should I reflash omni again? and NOT touch anything ( actually I didnt do anything except use trickster a little)...

edit:

I will do and give you anything I can and you need.. maybe it's my imagination and it should work like this?

I'm not a total noob(i hope) but I think something is dead wrong, reflashing again maybe works but I am really doubting it, my only chance could be changing governor..
[LG Optimus 4X HD] ezet:
I couldn't receive or make calls no matter what. Switched 2g/3g the problem persisted and i had no data at all. I am sorry i can't provide a log since i was out at that time and i've skipped from using this kernel since i lost some calls the other day and i don't want it happen again.

I believe you mean not all roms support init.d . Most, if not all, third party roms support it i think. Also there are alternatives for people using a rom that doesn't support init.d like this https://play.google.com/store/apps/details?id=com.androguide.universal.init.d .

Even more you can grep for init.d support and if not inject it.
[LG Optimus 4X HD] iodak:
Then it is ok from kernel side something is using lot of cpu power. [MENTION=2236955]Zhus06[/MENTION]
[LG Optimus 4X HD] iodak:
No i mean kernel. I will see what i will do. I somebody doesnt like dont have to use it. You can always reset everything by flashing rom.

[MENTION=3506654]Flying_Bear[/MENTION] what gapps package are you using ? And how did gapps managed to screw up kernel ?
[LG Optimus 4X HD] ottomanhero:
I agree with [MENTION=3506654]Flying_Bear[/MENTION].This kernel got some lags in asphalt caused by I/O.I tried everything FStrim, diff governor - readahead cache values but it's still not as smooth as OP kernel.Could you please cherrypick IO stuff from OP kernel? It'd make this kernel perfect.
[LG Optimus 4X HD] Flying_Bear:
Dunno how but i had kernel panics quite often, with beanstalk, while noone else had them (i used p.a. moudlar minimal package). Now using some minimalistic package with only play services and play store, and i restored apps via titanium , so it works no problem. iodak suggested it may have something to do with google+ (it didn't), so i decided to replace whole gapps package.
[LG Optimus 4X HD] mario.gacv:
Sorry but I didn't undestand well, could you give me an example for these settings: 200 250 300 350 400 600 & 250 300 350 400 600 600

Thank you very much :)

It stable in mine case to ~560 on 1150 so i raised voltage only if to goes higher then that.
[LG Optimus 4X HD] gingerboy92:
i have to ask, are you running the latest omni? can you help test the new vanir? i have been having a very similar problem. heating and really bad screen on time besides that the cpu is not entering lower frequency states. also, try testing the unofficial cm11(that are compiled using p880-dev sources). if anyone else feel like testing, please.
[LG Optimus 4X HD] Conquerora:
My phone acts similarly. After a clean install it works as it's supposed to. Then after a few weeks wlan and baseband wakelocks come in...making standby and screen on times terrible. I also could not get cpuquiet to work properly on iodak kernel. Surprisingly, it works fine on Zaiben kernel (very close to stock, I think).
[LG Optimus 4X HD] moddroid:

[LG Optimus 4X HD] Zhus06:
I found out that freezing all apps from PA_gaps_minimal fixed it... so I tryed other gaps AND LOOK WONDERS it WORKS!

Although I am using stock kernel from omni now I can confirm that PA_gaps made me weird troubles..

I never liked PA team stuffs now they just helped me dislike it even more..

[LG Optimus 4X HD] DeeZZ_NuuZZ:
It's the variant of your cpu...means you can't UV so much and you can't really overclock....there are four , 0-3 and 3 seems to be the best...but sometimes also 0 can handle the same like 1-2 can :b fifth core will be always enabled...it has nothing to do with that..

[LG Optimus 4X HD] Mr.LOVER:
Max CPUs ?

hi, i want only 2 cpus online, so i read on OP that we go to /sys/kernel/debug/tegra_hotplug/max_cpus and change it to 2 ?

am i right?

when i go there and open that file with text editor, it shows me some digits there? should i delete those digits from that file before putting there 2 ?

i see these digits in that file...

2147483647

but in min_cpus file, is 0 (ZERO).

is that normal?

what do i do?
[LG Optimus 4X HD] danny19901:
To do all this I use Tegra Overclock app from playstore or use Trickster mod
[LG Optimus 4X HD] Mr.LOVER:
those apps are not free!!
[LG Optimus 4X HD] danny19901:
I think you can do in free version of trickster I believe
[LG Optimus 4X HD] Holzi001:
Yes, he can! :thumbup:
[LG Optimus 4X HD] Mr.LOVER:
ok, through trickster i have selected max cpus to 1, but still i see all cpus are working...
[LG Optimus 4X HD] danny19901:
Strange should work but to be honest I have never used Trickster to do this I use Tegra Overclock and i know it has to be paid for and can't be cracked what so ever as dev told me but its awesome I will say that but trickster should work or try some other free stuff out there but there the main 2 I know of
[LG Optimus 4X HD] Mr.LOVER:
just got it working with trickster, all i had to do is to click to activate on reboot and then reboot my device, and max cpus for some reason only work when you reboot :)

thanks for the hints, now it's working as i desired.

[LG Optimus 4X HD] iodak:
It is not impossible to upgrade to 3.4 it was already done from kholk but it need a lot of work and time. I did patch and build 3.4 but it is not booting. Probably some security issue.
[LG Optimus 4X HD] daniel.mota:
Cyandelta is an app from play store that allows daily updating of CM nightlies with small downloads (about 10 MB per update).

IODAK, I think I found a fix for the frequency locking. My battery dithers over the temp_throttle_skin limit, so I typed this:

echo 60000 > data/local/tmp/temp_throttle_skin

Mr iodak, quick question...

Trickster Mod or Tegra Overclock? Or?

(can anything gpu Overclock in app rather than scripts?)

I can't seem to get the init.d scripts to actually work following your guides in the OP
[LG Optimus 4X HD] moddroid:
To overclock gpu add this line to any script in init.d folder ( you don't have to modify permission):

Echo freq1 freq2 freq3 freq4 freq5 freq6 > /sys/devices/system/cpu/cp0/cpufreq/gpu_overclock

I'm on PA 4.4 and work great. ;)

Or you can use tegra overclock but is a bit buggy :(
[LG Optimus 4X HD] Ben36:
How do you actually check its working tho?
[LG Optimus 4X HD] moddroid:
Yes yes i have rebooted just five minutes ago and the frequencies are correct :)

You simply open the file /sys/devices/system/cpu/cp0/cpufreq/gpu_overclock with a root file explorer and see if che frequencies you wrote in che command are there.

[LG Optimus 4X HD] Ben36:
See i do and there is never any changes :-S
[LG Optimus 4X HD] Ottonet:
Then you are doing it wrong.

Editing those files can be tricky, at the beginning, it becomes easier as you get accustomed to some small rules.

1) do not edit them with PC editors. It is a lot easier to edit a init.d file on a PC and push it through adb. But PC files do have a couple of characters at the end of each line (Carriage return-line feed) which get the file invalid in UX OS's (in Android, there must be a single line terminator). Therefore it is safer to edit them with the editors that come with file exploring apps on Android (unless younhave a Unix system, based PC)

2) give correct permission to the file. To be sure, check from one if the already existing file in init.d directory. In order to visually remember it, I like to imagine permissions as an upside-down U letter.

................R.......W......X

Owner....x........x.......x

Group.....x.................x

Others....x.................x

3) give the file the correct owners, that are Root (000) as file owner and Shell (020) as the group owner.

4) reboot your device prior of checking the results. The file you are editing does nothing by itself, it is only a collection of commands (write something into other files) that are executed at boot.

EDIT: (just to keep all infos in one post, in case somebody else needs them)

Each file in init.d directory, in order to be executed, must begin with the following statement, put in a line on its own:

#!/system/bin/sh

Inviato dal mio GT-P3110 usando XDA Premium HD app
[LG Optimus 4X HD] Ben36:
I edited them in es file explorer, set the permissions all like you just said and rebooted, but nothing ever changes. I don't get why th :-S
[LG Optimus 4X HD] Ottonet:
The first line in your files should always be

#!/system/bin/sh

Is it like that?

Another thing that is happening here AND I don´t have seen it never before is that when I charge the level indicator of the battery starts to go lower not upper, example: I start charging my battery with 50% and it goes to 49%, 48%, 47%.

Now my battery "fills" overnight, I left it with 26% last night and woke up 8 hours later with 30% ! ! !

I think it's rom related, or battery miscallibration.
