How to make your own init.d script
Hey fellow XDA users!
I'm creating this thread as I've seen a countless number of times the same question asked (literally hundreds)
'How to I set (_____) on boot?'
Finally I have come around to answering that question! This thread will allow you to control system/kernel parameters on boot
Now many of the kernel devs around the HOX forums have created some pretty epic kernels with tons of features which can be modified as much as the user wants and now I'll be showing you how to set these parameters on boot without the use of apps! :laugh:
Requirements
Rooted
Busybox
Custom Rom with Init.d Support (Most custom Rom's, check in OP of Rom thread)
A Root File Explorer (We're going to do this through the phone)
Stock ROM does not support init.d
If you're on a stock rom, you can easily add init.d support using Ryuinferno's very very helpful thread!
Enable Init.d Support
Once you've done that, come back and follow the instructions
Now to begin, let's look at a typical init.d script
Code:
#!/system/bin/sh
#CPU
echo pmc > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 1200000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
#Smart Dimmer
echo 1 > /sys/devices/tegradc.0/smartdimmer/enable
#Fast Charge
echo 1 > /sys/devices/platform/htc_battery/fast_charge
#S2W
echo 1 > /sys/android_touch/sweep2wake
OK, now to a new user this may seem quite confusing but once broken down it can be easily understood:
#!/system/bin/sh = This is required at the start of every init.d script
echo .... = Sends the command
'<insert value here>' = You can put a value after 'echo' and it will send that value to the file you have shown the path to, e.g. 'echo 1 >...'
>/.... = Specify the path and file in which to change on boot
So for example if I put this in my script:
echo '1' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_voltage
I am changing the file 'gpu_voltage' to 1, allowing gpu voltage to be enabled on boot (currently only XM's & Alex-V's kernel)
Similarly with the command:
echo '0' > /sys/class/leds/button-backlight/auto_bln
I am disabling auto-bln on boot
Hopefully after you've read all of that, you've understood a little more about init.d scripts
Now let's actually create some scripts
Instructions
We'll be using a file explorer on Android since Window's editors don't format the text correctly
1. Create a file using your choice of file explorer, I'm using Root Explorer and put it in /system/etc/init.d/
2. Open the file and write the following into it:
#!/system/bin/sh
3. Then choose which file you want to modify on boot and what value you want to change it to, and write the echo command and path into the file
For example: echo interactive > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor - (for interactive governor on boot)
echo 1200000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq - (for 1.2ghz on boot)
Now there's some things to look out for when doing this:
• You need to make sure you're pointing to the file not just folder when entering the path in '> /....'
• You need to make sure you put the spaces in the right places and don't put any spaces in random places
• When entering multiple values you need to put the values in quotation marks like this "....." - so for example if I want to set max GPU speed I would do this:
echo "416 416 416 416 304 304 247 247" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
• Also if you put a '#' in front of the line of text then it ignores that line, as you can see in my example I have a line that says '#CPU'. This is just to tell me I'm making modifications to the CPU and so I put a # in there so that line is ignored (the echo command below it is still carried out)
• You can do all the commands in one script and do as many as you like!
The various parameters that can be controlled are most likely on the OP's of the respective kernel threads (it would be ridiculously long if I were to put them all in this thread)
4. Once you're done, save and exit the file
5. Then rename it with a number in front, this number will decide which init.d script will run first (lower the number the earlier it's run on boot)
So for example I named my file: 25kerneltweaks
It doesn't really matter what number you put but just make sure there's no other scripts running after which will also change kernel parameters (leave them but just give your script a higher number)
Almost done now!
6. The final thing you have to do is set permissions:
Now you won't be able to use ES File Explorer for this step as it just can't set the right permissions for init.d scripts for some odd reason, preferably use Root Explorer but others should work (except ES)
Set permissions as rwx-rwx-rwx (shown in the image)

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you don't have Root Explorer or a good substitute you could also do this through terminal emulator:
To do that enter this into emulator (press enter after every line)
Code:
su
chmod 777 /system/etc/init.d/insertfilenamehere
And permissions should be set
And that's pretty much it folks
You have successfully created your own init.d script!
Many people prefer this method as you don't require apps to set stuff on boot, now it'll just be done automatically for you :good:
Btw this will work on any android device, so if your a wandering googler (is that even a word ) searching for a guide like this, it should work on your phone/tablet as long as you fulfill the requirements
Hope you guys found this useful, it's the first thread I've made so sorry if it's a little rough around the edges and
Press thanks if I helped and please rate the thread, I'd greatly appreciate it!
now all who have this questions can make their own script every time they ask if somebody else can do -.- ... good guide mate i always do that with smanager but some ppl are then confused ._.

Thanks! I have a question: I tried to set a different max cpu frequency by using this command for my device echo 2107680 > /sys/bus/cpu/devices/cpu0/cpuinfo_max_freq
via adb shell and Root Explorer but anytimes I save the file it back to original value.
I also put a new init.d file within that command with no success. Why that?

Hi, unfortunately it doesn't work. I also made a stand-alone script (below)...

Hello
i want to expand the memory a little bit
so tried to use
Swapper - https://play.google.com/store/apps/details?id=org.azasoft.free.swapper&hl=en
Swapper 2 (for root users) - https://play.google.com/store/apps/details?id=lv.n3o.swapper2
then testing with free command on the Terminal Emulator
but it's still showing me that the swap equals to zero
so my question is "does CM9 support swap file"
and if yes "how can i create a working swap files"

If you're using Arco's CM9, then I can say: Yes, it supports swap files. See below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As for "how to create one" ... here's how:
1. Creating a Swap File
Determine where you will place your swapfile* . For purposes of illustration, I will use /xxx/yyy. Remember to change this to the actual directory!
Open Terminal
Enter these commands; do not type the numbers, remember to replace /xxx/yyy with an actual path, and replace zzz with the size of swapfile you want (in MiB)
Code:
su
cd /xxx/yyy
touch .SWAP
dd if=/dev/zero of=/xxx/yyy/.SWAP bs=1048576 count=zzz
mkswap .SWAP
Test the swapfile with the following code, again in Terminal:
Code:
swapon /xxx/yyy/.SWAP
free
Once you see that the swapfile is working, turn it off again.
Code:
swapoff /xxx/yyy/.SWAP
2. Activating Swap File on Boot
Download the attached 99swap.txt
EDIT the downloaded 99swap.txt !! You must replace /xxx/yyy with the actual directory.
Optionally, replace the SWAPNESS value (range between 0 ~ 100)
Make sure you have a working init.d! If your ROM does not support a working init.d, then stop; see next section
Rename the file to 99swap
Copy the file to /system/etc/init.d (remember to mount /system rw first)
Open terminal, and enter the following commands:
Code:
cd /system/etc/init.d
chown root.shell 99swap
chmod 4755 99swap
ls -l 99swap
Reboot your phone, and check the logfile, which should be /data/local/99swap.log
3. Activating Swap File on Boot using Script Manager
Download Script Manager here
From within SManager, find your edited 99swap.txt file, and tap on it
Activate "Root" and "Boot" buttons, then tap on "Save"
Reboot your phone, and check the logfile, which should be /data/local/99swap.log

One tip : Change the SWAPNESS value to 40. After extensive testing, I think 40 is better than the current value of 20.

thanks for your method, it works very well and I solved the problem with the ram of my I8150 and some related freezing.
I have only a problem with the activation on boot, I followall the steps but in the log file is always explained that "the directory ttt/ttt was not found. Is it mounted ? " (ttt/ttt is the correct folder of the .SWAP file).
I have this problem either on internal and external sdcard (I prefer the internal because it's too quick without lagging).
Can you help me understandig the problem ?
Thanks a lot and sorry for my English.
I run on Samsung I8150 + Cyanogenmod9 rc8 - fully working with 350 mb of swap file on internal sd (reserved for cwm backup and swap, I used the CM9 option for cross the internal and external sd.

Yeah, it seems some ROMs mount the directories late; when the script triggers, the SD cards (internal/external) are not there already.
I have been playing with nohup command, but I just can't get it to run reliably on such ROMs.
So, I suggest going the SManager route instead. It's much more reliable. Besides, you really *don't* want to use a Swapfile during Boot; it slows down things because when the kernel sees that swapfile is available... it starts swapping (almost) right away. You'll need Swapfile during normal usage, so activating the Swapfile after the phone finishes booting actually makes more sense...
(BTW, I'm sorry I can't maintain this anymore... I no longer have my W; it's been handed over to my little-brother-in-law, and I've moved on to a new phone...)

thank you very much for your reply, I understand that is not mine mystake if it'sn run
I will continue to launch the swap file using the terminal emulator and swapon command but...
as the folder addre is too much long and write it anytime manually in the terminal emulator is possible to create some script or anything else to be launched manually without writing anytime all the command line (similar to an .bat file,sorry I don't known linux and on , I'm still a winzozz slave..) ?
sorry for my bad english explaination, and in any case thank you for your interesting and support.
best regards
+++updated+++ I solved in the terminal emulator - left touch for setup - initial command - I wrote
'su' - "press enter"
'swapon /xxx/yyy/.SWAP' - "press enter"
now everytine I open the terminal emulator the swap file starts automatically, so I need only to tap the app and after exit.
too easy,too quick

How it works:
1. Each boot.img packs zImage (real kernel) and ramdisk (special files for kernel use)
2. This one has all modifications from LGGW rootboot by Justin Case:
a. Adds su binary, superuser.sh install script, modified install-recovery.sh and additional step into init.rc file to invoke superuser.sh install script. Also modifications to mount system as rw and some disabled security.
3. So basically it mount system as rw and does following (cut from superuser.sh install script):
Code:
#!/system/bin/sh
/system/bin/mount -o remount,rw /system
/system/bin/sleep 2
/system/bin/cat /sbin/su > /system/xbin/su
/system/bin/cat /sbin/su > /system/xbin/daemonsu

/system/bin/chmod 06755 /system/xbin/su
/system/bin/chmod 06755 /system/xbin/daemonsu
/system/bin/chmod 755 /system/etc/install-recovery.sh

I have dumped the rom from my debug/test version and was wondering if you were able to give me a guide on how i could try and flash it with a retail version? I presume this root guide probably won't work for me
Well, if hardware and partitions are the same - I do not see why it will not work. However, it will not help to flash.
I might try to compile twrp, but will have to carefully read its docs first.
thanks @XorZone confirmed as working and a nice easy process too (I was already unlocked).
Out of curiosity, modded LGGW rootboot or just renamed?

Thanks for letting me know!
I reverse engineered changes in LGGW by unpacking and comparing ramdisks from both rootboot and original lg kernel and then applied the same changes to our kernel extracted from PC Companion files.

that's awesome man! will purchase mine next week, can't wait to root it. thanks for the answer.
Thanks for the root, XorZone. For anyone wondering, here's the dmesg of the watch
A few small observations from digging:
The main chipset seems to be the BCM23550
The CPU has 4 cores, 2 are disabled in software. Should be easy enough to reenable if you please
It definitely has WiFi hardware, but the firmware is currently missing from the image. If you mange to get a hold of compatible firmware and nvram, it should be simple enough to get WiFi up and running
The WiFi firmware message mentions a "43341". Which is odd because apparently the main chipset does have WiFi support built in. Searching for a Broadcom 43341 gives you this, but this might just be a red herring.

Yeah, I noticed the same about WiFi chip, it might be that they packed bcm43341 as part of the BCM23550 soc, like Invensense MPU9250 chip packs mpu6500 inside.
For the 43341 I'm finding it in the configs here: https://android.googlesource.com/kernel/tegra/+/bdde9f16131a5ac2039062d5ce22e3e153acbe68^!/
Looks like BCM43341 is BCM4334 + NFC chip, so we could try S3 I9300 files as per http://redmine.replicant.us/projects/replicant/wiki/GalaxyS3I9300Firmwares

I've confirmed root survives the Lollipop update
Wow, I was out whole weekend, will have to catch up with the update
Hello from the V10 Forum! This is a mod I created and posted for V10 users, but as various devices use Qualcomm hardware and similar operational conditions, the biggest similarity being Linux , and by some requests from others here to post this, I am offering this modification to other devices as well. It is already thoroughly tested and the logic and rationale behind the conditions are cross compatible with many Linux systems/machines anyways. You should see positive results just as everybody else has.
You must be rooted to apply this mod.
**SEE POST 2 FOR CHANGE LOG**
***VERY IMPORTANT IF YOU ARE GOING TO USE THIS MOD, you need to navigate to the /system/etc folder on your device, and rename any files that exist in that sub-folder that have the words "ZRAM" in them to have a .bak extension rather than a .sh extension so it does not run at boot.
You will also need to navigate to the /system/bin directory with a root explorer and rename the "mpdecision" binary to "0mpdecision.bak" .... The added 0 is just to move it to the top of the list of files so you can find it easily if you need to.
This is a step by step instruction on how to replace the /system/etc/init.qcom.post_boot.sh file for the device. Be it known, however, that this instruction (and file) can be used with any device running the Snapdragon 805 SoC combo.
What does this do?
Simple. It turns your device into an even more efficient powerhouse. Here are is a list of everything done:
-Interactive Governor tuning for performance and better battery life, a quick description of what I did...
-low load, quick response, low frequency
-high load, quick response, higher frequency
-modified input boost settings for Interactive
-Locked cpu cores on - your battery life will not suffer, don't worry.
-Modified a bunch of system permissions to remove samsung garbage from controlling hardware.
-Switched IO scheduler to noop, and tuned accordingly
-Adjusted minfree values (RAM management, it is a little more multi-tasking friendly)
-Adjusted VM parameters - swappiness, dirty ratios, cache pressure, centisec values, etc (again to complement multi-tasking... your data will hang out a little bit more before being written to disk, but house cleaning won't happen all at once, so there is still good performance and your system won't bog down while it is flushing the toilet)
-DISABLED zRAM!!! - I have no idea why a device with 3 GB of RAM has zRAM enabled. This is purely a waste of CPU cycles and other system resources. You want physical memory, not compressed memory.
-Changed congestion algorithm to cubic (better network performance... assuming the network bandwidth is already there
-Cleaned up the shell file and fixed some errors.
-Removed calls to mpdecision
-More to come!
How to do this, we'll just get right to it.

Very important you put the file on the root of your INTERNAL SDCARD!!!
Do not forget to do this.
After you do that, open terminal emulator, and type the following commands in the order they are presented (I would highly recommend just copying them from this post one by one and switching back and forth between your browser and the terminal app):
Code:
su
Code:
cd /
Code:
mount -o remount,rw /system
Code:
cd /system/etc
Code:
rm init.qcom.post_boot.sh
Code:
cd /sdcard
Code:
mv init.qcom.post_boot.sh /system/etc
Code:
chmod 0644 /system/etc/init.qcom.post_boot.sh
Double check the file has been replaced with a file explorer of some sort, double check permissions, then reboot. Good to go.
***CHANGE LOG
5/14/2016
-Modified scaling up activity to be a little less aggressive, this should help battery life quite a bit
-Switched scheduler to cfq and tuned it, huge increases in io throughput - the new cfq should be used for these devices, no comparison in performance to any other
-Moved. above_hispeed_delay module down the pole a bit (moAr batteries)

the note 4 has 3gb ram..?
So just copy and paste and hit return after each line in terminal
Edit: i think it worked because my i/o is set to noop now
Sent from my Not4 Mod using Tapatalk
I just did this the old manual way in root explorer. Added .bak to post boot instead of .sh, copied the new post boot to system/etc and changed permissions. Added .bak to mpdecision. No zram files for us to edit. Rebooted. Ran antutu with a 5,000 point increase. With MM I steady got 70,450's and now.
This is great for now until we get some well built custom kernels. All the roms I flashed since I had the note 4 from launch day, and I don't think any devs worked on tweaking the post boot like they used to on the HTC eVo line like I was used to.

Well my experience with this is odd. I did what Death-Dealer suggested and I can tell things are working faster/better but my antutu score went down instead of up. As long as I'm happy with the performance I guess it doesn't matter what antutu says.

Sounds interesting.....would you mind linking to v10 forum so i can read what experiences people are having? Thanks and thanks for your work and time.
Last question (for now ) any reason this wouldn't work with a ported S7 rom?
Edit nvrmd found some threads......reading now
Awesome....something new haha. Thanks bud. I'm currently running Tekhds rom and using Kernel Adiotour with Senthils Nightmare profile and Project Skynet mod......is it a bad idea to try this while using those? Thanks in advance and thanks for your hard work too.
Good info. Thanks.

I'm running RR 5.6.8 on Marshmallow and I'm not seeing any of the files you listed on my phone. No ZRAM files, no mpdecision, and there isn't a init.qcom.post_boot.sh already on the phone. I went through the steps any way just to see if it would do anything and it all worked successfully, but I can't really comment on any performance gains. Is this a Kitkat/Lollipop only mod? Perhaps MM got away from the same file that this is intended to tweak?
Thanks for your help either way. Looking forward to trying it again when I have a rom it's intended for.

Yes that is the value for internal SD. If you scroll down you will find the one for external SD. It is set to 1024 in the file. I set mine to 2048 as it provides better performance with my SD caRd
NOTE:
1- First tnx to @soniCron for his amazing work for governor profile... here
2- I edited GhostPepper in to the init.d script and values completly with XZ cpu cores frequency.
3- No need to run terminal any more for set profile at any boot! or use third-party kernel manager or profile manager apps. only copy/past, set permissions, reboot and BINGO
BACKGROUND:
I test Butterfly (from HTC10) profile and MadDog from (Nexus 5x) and edit that for xperia xz. After multi time test and check diffrent values... i fine GhostPepper v1.3 is a complex of smooth like butter, good performance in games and best battery life for day to day use.
Quote from @soniCron :
Uses a quantized, frequency-aligned parametric curve to influence low core clock rates while providing extremely smooth transitions from each clock rate and exceptional battery life. The current favorite, albeit not very well tested so far. HIGHLY RECOMMENDED

REQUIREMENTS:
1- rooted xperia xz
2- enable init.d (see post2)
3- TWRP recovery installed (for enable init.d)
4- any file manager with root browsing feature. (or use twrp built-in file manager!)5- enough knowlage about linux permissions, governor, init.d
CREDITS:

5- go to advanced/terminal and run built-in terminal
6- type this commend line by line in terminal:
Code:
cd /sdcard

The interactive tweaks change to cpu clock jump step. In medium usage like web surfing or lesson to music you don't need max freq.
Now cpu need more time to raise to max frequency
This profile set gpu clock at maximum for little frame drop in games (play AAA games drain battery fast)
If you no need that only delet init.d folder or delet governor file.
please, help!

Can you make one for drunksauce gov it's the best on Nexus 5X and is used in D.U. has crazy SOT on my Nexus can we get this ported to XZ. If not what do I do to get it ported just open the init file and edit the frequencies and how many CPU like ex: cpu0 cpu1?
Well I tried to port drunk sauce my self using the 99gov for Xperia XZ I found in this thread as a reference for the frequencies on our device. I'm running it now can confirm it is a success. I'll m working on it over the week. If anyone wanna try and give me feedback that be cool. I'm noticing a small drop in proformance in stamina mode but there no lag and SOT seems to be great. Give it a shot :good:

New update to my DrunkSauce port now on Version 4, Noticed that when I was checking CPU statistics I was showing the most used frequency on LITTLE Cluster was 1593MHz, Also noticed the associated battery drains from this. Added 3072MHZ Target load to LITTLE Cluster and Also changed the Input boost to have LITTLE Cluster firing at lowest frequency 3072MHz for CPU cores 0-3.
Enjoy!!!! Because im loving this thing right now buttery smooth and power saving.
