Is there any way of modding cpuinfo_max_freq without custom kernel?

Is there any possibility of modding /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq without modding the kernel?
Just in case you don't know, cpuinfo_max_freq is the file that limits the maximum processor speed to 1000mhz.
cpuinfo_min_freq is the one that limits the minimum processor speed to 100mhz (i've no interest in modding that file).
I know i can acquire this with a custom kernel or by modding one myself, but i'd like to know if there's any way of doing this other than with a custom kernel.
Tried using root explorer and change permissions to write too apart from read and then modding, without success.
Tried changing permissions using root explorer and then using an init.d script
Tried a few more things, but so far none have worked.
Thanks

You did everything correct but one thing more open root explorer.
# Go to desire file (make sure you have it on rw)
# Now press and hold the file
# a menu will popup
# go to open in text editor and you can edit it
Enjoy

i have just tried it.. normally when i change any system file with text editor, i click on "save&exit" and it says it is saved and the original file is named as xxxxxxx.bak..
but this time there is no .bak file and the original file is not changing.. i write 1200000 but when i try to open it again it turns back into 1000000 ...

Tried that too. Root explorer says it's modded it but if you open it again, no change has been applied
Apparently, it's read only even after changing permissions.

or that file is modified by something else all the time.. obviously we have to change something else before that..

The kernel. Just wanted to find out if there was another way, it'd be much simpler than modding a kernel. It seems there isn't

Just a trial idea, copy that file to as card, then edit it. See if it saved then, then rename old one as xxxx.bak and paste the edited file there.
I can't do it as I am on a custom kernal and i am able to change it as I said.
Check it out and tell if that's any help

Its impossible, i tried this command on terminal: echo 1800000 > /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq it says permission denied (i was su)

think you have to edit the init.rc file

[MOD] Enable init.d scripts support on stock kernel

Hello!
This is a small mod, inspired by non other than our great DoomLord (so if it helped you, thank him/donate to him/worship him ) and his thread in the X10 section.
I am trying a lot of things on my phone, so I often switch back and forth from stock kernel to DoomKernel.
However, I use lots of init.d scripts (my favorite one being SuperCharger)
and I just don't want to lose this feature when I'm on stock.
So, without further ado, here are the steps that are needed to make init.d scripts run automatically at boot on stock kernel.
Requirements:
1. Stock Kernel
2. Root
3. Busybox
4. CMW Recovery for Stock Kernel by nAa.
5. Root Explorer or any other similar app.
Instructions:
1. Download the attached zip and place it in a folder in your SD card.
2. With Root Explorer, go to /system/etc. Press the Mount RW button on top right corner.
a. If the file install-recovery.sh is not there, then press Menu and create a New File.
Name it install-recovery.sh and then long-press on it and select Open in Text Editor.
Paste this text in it:
Code:
#!/system/bin/sh
# init.d support
busybox run-parts /system/etc/init.d/
Save it and delete any .bak file that Root Explorer might have created. Set the permissions as in the attached screenshot.
OR
b. If the file install-recovery.sh is already there, long-press on it and select Open in Text Editor. Paste this text in the end:
Code:
# init.d support
busybox run-parts /system/etc/init.d/
In both scenarios, don't forget to leave one empty line at the end of install-recovery.sh file. ***
3. Reboot into Recovery and flash the init.d-autorunner-stock.zip.
4. Reboot your phone and with Root Explorer go to /data/local/tmp.
There should be a txt file there named "init.d_log_test.txt" and once you open it, you should see the word "done".
5. Now you can use your favorite init.d scripts on stock kernel!
If you want to check if the scripts you want to use actually work, please refer to one of my older threads about how to test them.
*** I am not including an install-recovery.sh because this is the file that Link2SD depends on, so it's better if you modify it yourself, rather than use mine.
Let me know if it worked for you!

This is a setup in order for scripts placed in /system/etc/init.d to be executed automatically at boot. Such scripts can do lots of things, like RAM optimisation, CPU scaling, mount options, etc etc etc.

Can the script be added to hw_config.sh? Will it be execute on boot? Inteks' swap2cache script can be added to hw_config.sh too.

Sorry, I don't know for sure. But probably yes.

Great post mate, thanks. (already give you thanks button)

Seeing if this works on ray
I get this file in the init.d folder after.flashing the file
#!/system/bin/sh
touch /data/local/tmp/init.d_log_test.txt
echo "done" >> /data/local/tmp/init.d_log_test.txt
Not in data/ local
I have ran supercharger script and files are appearing in inlit.d folder think it's working
Edit : tested it as per the thread further up it would seem its all working!
Sweet
Hope it is ok I have shared this on the Ray thread? (I have linked back to your thread)

Hi iridaki thanks for your little mod here! I just want to give a hint of what might been a little issue but might make your whole mod is not running. You do mention about changing permission on install-recovery.sh, but you gave it as a picture. The Problem is XDA on web these days is not arranging the image as inline, but as an attachment. So i and chiefy009 did the same mistake, not changing the permission because it is just a one line and not clear enough. Please add additional step like:
3. Make sure install-recovery.sh have permissions of rwxr-xr-x

Overclock Error?

hi al i tried to overclock my w8 tonight and when i downloaded the oc file from
http://forum.xda-developers.com/showthread.php?t=1020313
and paste it to system/lib/modules it says copy error file not found (read only system) what is this? any solution ?

you use root explorer? up you see a small rectangle button, with a r/o or r/w, click on it and try again.
sorry my bad english

ohoh okay ! downloaded root explorer now is fine ...wait i try if i can finish it!

i dont get what does this mean
-edit hw_config, add line insmod /system/lib/modules before battery fix command

lol
go to system/etc, find the file hw_config.sh, click on it until a box appears, click on open with text editor and put theline you said..next save and reboot or upload your hw_config file that i make for you lol..you use stock kernel right?

ya stock ..i use rename ...am i wrong?

rename?? rename what?? just make what i said in post above if you see a line: "#battery fix bla bla bla" put above this line

wait choose which option? view / execute ?

theres a rename option ..i used the rename just now and nothing happened

just put the file in system/lib/modules, reboot and use an app called setcpu or no-frills cpu to oveclock the device.the line you said already exists in hwconfig file if you use gingerDx

ARRR i still cant!! i click edit using text editor at the front i typed in
insmod /system/lib/modules/x8oc.ko # x8 overclock
rebooted
nothing happened! =(

look at my post above i edit

ohh...YEAAA DONE!! whats the point of
nsmod /system/lib/modules for?

[TOOLS][script] ROM Tools v2 (Kernel Extractor)(BML15 IMG backup)

ROM Tools v2 ​
Version 2 BETA
v2b (Officially v2)
Linux Script
by iamareebjamal
Automated Android script for extracting boot.img and bml15 partition​
My PC has issues so I can't use it to build mods and scripts, also, I have a very slow internet connection. That's why I don't upload my ROMs. Provided, I build EACH and EVERY one of my mod on my mobile, including those long scripts with repeating commands and making it easy for other guys to use, I could've just created a script with two commands which rendered error if used incorrectly, but I make it noob proof in every way possible so that there are minimum errors from your side and if something gets wrong, you know what it is. Even uploading 5 mb of mod makes it very difficult as I have to reupload if it fails. Writing scripts on mobile is not easy, you'll know if you have done it, it takes hours. Also, these colorful and easy guides are also made on mobile by writing BB codes ONE BY ONE by hand.
I am telling you because a person day before yesterday posted my Amazing Sounds Mod in another forum without my permission. However, he has removed it now. My work is fully open sourced for you to learn and make your own mods. But taking part of my work and posting as yours is not appreciated.
The MOST you can give me is love, prayers and Thanks

Out of the time I was absent from XDA(13 hours ) , I was searching for a method of extracting the kernel from your ROM
Imagine, you want to extract boot.img from your ROM but don't know what to do, you don't have internet to download the stock or custom kernel or simply want to extract it?
I did not find anything except the solution of Android Kitchen but what if you want to do it on your android?
As a bi product of this search, I got a lot of knowledge about the partitions used by Android system and the blocks that define them.
I also got basic knowledge about Linux Scripting.
So, I created this script that backs up your boot.img and bml15.img partitions.​
​ boot.img - kernel of your device
bootextractorv2.sh - Backs up your kernel
bml15.img - IMEI partition
bml15extractorv2.sh - Backs up your IMEI partition
Note:- SGY Toolbox also backs up and restores bml15_EFS.img. And that also with a nice user interface, I just created this mod, because I wanted to but I recommend newbies to use SGY Toolbox for backing up IMEI
However, I found no tool able to backup the kernel, so it may be very useful for some members

nice tool for kernel backup... :good:

Doesn't work for me, S5830i stock firmware. If I use script manager method, a lot of "not found" messages, and finally the boot folder is empty. I give script manager root permission. And if I use a terminal emulator, the same error messages, finally there is a 5MB boot.img file, but "untouchable". I can not copy in any other folder. If I connect to PC, boot.img is missing. Appears again in the mobile when I disconnet the USB. I can not change file permissions with root explorer....
Also when the script ask if I want to create a zip file for recovery, I select 1 and I get "bad integer, run again"
Thank you

You have busybox?
If no,
You can't run it

Yes, and the script founds it (it says). Finally I zipped boot.img with root explorer and that zip file could be copied to the PC. Guess the file is ok. Thanks.

Why you zipped it?

English is not my language. I explained that boot.img was untouchable. I tried to copy to computer and I always got writing errors. Rebooting wasn't useful. Permissions couldn't be changed with root explorer.. The file was there, but couldn't do anything with It. Tried to zip it and it worked, and I copied the zip to my computer..

Sure that there is problem in busybox applet sync
I don't know why script couldn't detect it

I don't know what the problem was. I installed, not without many problems, the last busybox available, and everything worked ok. Out of curiosity, I compared boot.img file extracted with "problems" and the boot.img extracted now cleanly, and are identical.
