Default [Guide] [MOD] Tweakers Kit...Modified init.d and sysctl system + Flashable Disabler

Warning
If you read this you may go blind and never become erect again.
And there is a possibilty a sattelite will fall from the sky and crush your house


This most likely can be incorparated into any rom on any phone
Feel free to post this anywhere and include it in any rom(Just Give Proper Credit)


I made this about a year ago .Works quite well
it makes tweaking very easy
designed to make tearing apart full tweak scripts apart and testing lines a nd full scripts e easy.
allows you to make up to 7 totally different init.d profiles . the ability to turn on or off any profile.
So now you can develop 7 profiles to boot from and run any profile in realtime
also gives you 2 sysctl.conf to boot from and two more to run in realtime

you need root and busybox

the contents of the foldet ( etc) go in /etc
the contents of ( bin) go in /system/bin the 6 files containing (run) need to be executeable
now you can put install-recovery.sh in /etc to get everything to run at boot
if you have Gametheorys kernel you can use the sysinit i provided in / system/ bin

if you already have either of these used by something else just add the lines from mine to yours


init.d
put scripts in the main folder like normal
there are folders in side
prof1 to prof 6
you can set scripts in those
the foldercalled Scripts is to store unused stuff
also is the initd control where you can use root browser root explorer or any scriptmanager to run the (on,off or run) scripts
Note, i cleaned out all my scripts but decided to leave the main folder with a setup i use the most Remove them or use at your risk

now you have
sysctl.conf through sysctl.conf4 in your /etc folder
load those with sysctl settings
init the init.d/scripts/sysctl are scripts to turn on or off sysct1 and 2 and run 3-4 in tealtime

More (run at will) profiles
init.run folder
load setups in run1 to run6 folders
at anytime use the control panel in init.run to exec any ofrun1 through run6

Note all profile folders have a subfolder labeled (a) those are just like pocket folders to store unused scripts

FLASHABLE DISABLER
This design has something very valuable
each profile has its own (applet) in /system/bin
the install-recovery.sh execs all init.d and prof1 through prof6 applets
but when you use the control panel to turn on or off the profiles you are sinply changing the permissions to each (applet)
So incase you put a bad script in and boots up in a loop or something else
i made a flashable zip of all the bootable (applets) with permissions all at zero
This will render all the bootable profiles un executeable
your new init.d script throws you in a loop flash the
InitdDisableall.zip below and reboot
None of the profiles will execute

So this basically gives you 7 init,d folders . you can choose which ones to boot from
for instance
i load one folder with my settings.one core turned off and cpu set at 810 and a clogged up conservative governor with agressive lmk

say i want to convert movies or play games i boot from an init,d folder i loaded with both cores at full cpu and multitasking lmk and a different governor set for speed

And i added a realtime run feature
this means i can exec any of these folders in realtime without rebooting
Then as an added bonus there is an additional folder that allows you to load your profiles to 6 more folders that you can easily exec in realtime without booting

the sysctl has the same idea
you get 2 sysctl.conf you can load with different settings and choose which one to boot from
plus 2 more sysctl.conf to load that you can run in realtime

The idea is to be able to have many Profiles of settings prefabbed and the ability to exec them quickly

This makes switching from performance and battery saving very easy

It makes testing and designing your profiles very easy as well

Now if you look at Sepero's Bootbuddy
it runs scripts at boot from the ext sd
this is awsome for me, when testing scripts i test some from bootbuddy
i use this for certain things like build.prop or certain kernel tweaks that i am not confident about
if this tweak causes a bootloop i can remove the sd card and bootup without the tweak
after several bootups with no issue, i move the tweak from bootbuddy over to init.d
But if you only want to use bootbuddy and not init.d i added 2 more bootable folders so you can choose from 3 profiles to boot from or turn all off

HOW To Develop your profiles

When i start on a new phone this is my formula
first i find supported govenors
i choose the slowest governor
then make an init.d script to load the governor of choice at boot
Then i clog up the governor,this means i slow it down
I change the settings so it doesnt scale up very fast and scales down instantly
Maybe lengthen the duration between mpdecisions
This is awesome for battery use and further testing

Next I want to start chopping away at the cpu, So I remove all cpu cores but 1
then limit the cpu to a lower scale
I usually start nat around 900 mhz

Example
The lg motion with Gametheory's oc kernel with added governors
i used the Conservative governor setwith
sampling down 1
up threshold 96
down threshold 95 ( or higher)
one core on only running at 918 mhz

So now your phone is much slower,Much better battery life but less responsive
do an antutu benchmark
make sure to look at the Details,each individual score
NOTE if you dont know how to get started
use an app like Kernel tuner
check the settings and selected run at boot with init.d
close kernel tuner it will create an init.d script for you
now go to your init.d folder and make a copy of the script
go back to Kernel Tuner and Disable the run at boot settings. it will remove its scripts
but you have your copy

Now for the ease of profiling you need to Batch your tweaks
small and identical for easy swapping and removal
like all vm tweaks in a script only ,net tweaks in a script only
and save the varied settings in a folder
when you are done you will have several folders of batched tweaks
forinstance various Governor tweaks like i posted below
The Ondemand Governor
A init.d script to load the Ondemand governor with stock settings
but it has 4 scripts for ondemand governor with Slower settings and 4 with above stock settings
Do this for every governor you use
The same with cpu max limits

From here on the idea is to chop away at the cpu but keep the score the same or better (when i am done i will run the phone at 594 or 702 but is close to responsive as the 918,and when i run the phone at stock or better phone is fassst)

Running the phone at core only and at lower speeds make its much easier to indentify the results of individual tweaks
Next you need to look at your system
/proc/sys is a good place to start
here are many settings we are gonna start changes to optimize our phone.
fs,kernel,net and vm settings are here
Its nice to know this as many phones have the same files found here but a few may vary
