REQUEST/IDEA for a safety script for tweaking/OC

I had an Idea for a script that would run at bootup, and if a certain variable had a "value" of NOT 1.
then the script would change the CHMOD of a userinit.sh located in the sd-ext from 050 or 777 to 750 then it would change the variable "value" to 0 were it would stay untill another script that runs at shut down or reboot setts the variable to 1 and changes CHMOD back to 050 or 777 so that the userinit.sh is not run.
That way if a change is made during operating the phone that causes the phone to crash with out shutting down properly the script runs which causes the userinit.sh to run and "resets" userinit.sh values to a "default". Otherwise if shut down properly nothing happens.
This could be expanded on to include repairing the EXT or clearing some special cache or other stuff I am unfamiliar with but that you might want to run after a crash.(like logcat?)
any way what do you think? any promise?

I think, for overclocking purposes anyway, making the userinit.sh unrunnable would make the phone break immediately, as I think it would go to the highest available frequency. However, I like the idea, though I'm not sure how to run scripts on shutdown. I think for overclocking, it would check if the shutdown was clean on startup, and if not change the applicable line to the next lowest number, which it would get either from a seperate file or maybe it could be stuffed in the script itself. (Just my somewhat uneducated thoughts)

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

most rom devs/tweakers launch userinit.sh by calling it with a sh
e.g.
/system/bin/sh /system/sd/userinit.sh
so it will still run !! ( as init doesn't care about permissions, it is god )
don't believe me?
Code:
echo "echo I ran" > /data/test.sh
chmod 000 /data/test.sh
sh /data/test.sh

Keep it simple. If a change in userinit.sh breaks your system, reboot to recovery and edit it and reboot again.

And I know that most roms now have a script called something like in /system/etc/init.d/20userinit that runs at startup and checks to see if a userinit.sh is present in sd-ext,if so it runs it.Also I noticed that the script can be there but if it is CHMOD to 777 it wont run. This is the "Reset script" Set to restet to something you like and run other tasks to help Fix/Diagnose probs.
The OC changes would be made from a different script such as 86supersettings
Or a userinit located in system/sd maybe ?
The thing is making sure one is read before the other.
Any way I probably will just learn the language better and do it from recovery console.
Thanks again

chmod 777 makes it rw and executable by everyone!!!!!!!!
have a look here
http://www.comptechdoc.org/os/linux/usersguide/linux_ugfilesp.html
but as I mentioned above, init ( the initial progam runs as root and doesn't care about permissions, ( it wouldn't be very good at doing initialising the system if it had to seek permission )

Yea your right. Well I said I wasn't that good at this linux stuff! Now I Proved it.
Any way as you can see this is more of a request..... I still think it's a good Idea.
Thanks for your help FireRat.

I understand how I could manualy Replace the modified script with a default one that was on my sdcard from within recovery after a faild OC change...but..
Are you saying I could actualy modify the original script from recover? Do you have any info on how? A link?

If you have RA-Recovery, adb works, so you can pull/push the userinit.sh script. You can also enter the terminal and use vi to edit it from recovery. You may have to mount the ext partition first, but that's pretty easy. "mount /system/sd" will do it, if /system/sd doesn't exist, "mkdir /system/sd".

Ok, Thanks that makes sense. I'm still learning adb though. And I tried vi once before with no luck. But now I know what to learn about.
Thanks a lot I appreciate it.

I'm not sure you need it,
this is for education value, if you want to play ^^^ is where to start

Thank You!
That is perfect
I need to add all of this to the startup script right?

I am going to use the beta boot up script from ZKX called 86Supersettings, but I could use a userinit/user.conf like most do. Correct?

well, a .conf file should be just that
a file with configurations , not an executable script

OK. I guess I meant both together. I would use the user.conf to make tweaks. Then have to modify the userinit.sh with the part you made. Something like.
#!/system/bin/sh--LEAVE THIS OUT. ITS ALL READY AT THE BEGINNING
if [ "`cat /data/cleanshutdown`" != "1" ];
then
echo "shutdown was not clean"
Dont run user.conf
and set cpu or other stuff to "default"
else
echo "shutdown was clean"
Run user.conf for tweaked settings

If I'm way off then I guess I need to re-read the Userinit thread.

well, in practise it doesn't matter
the file extension is only for use humans, if I'm looking in a directory and I see .conf I expect it to be a configuration file, I see .sh, its a shell script, .py python, pl perl .......

I see. Well Thanks again for your help. Your script does work. I tried it. crash on purpose.
I still have a lot to learn.

Folks;
1) If you're OC'ing via SetCPU, remember that this doesn't change the recovery kernel, and you can uninstall SetCPU from Recovery. From there, all you need is a "safe" userinit.sh.
3) If you're OC'ing via userinit.sh -- same deal. Your phone crashes on you and you just edit it to a safe config from recovery.
Tweak away.

This is what I ended up with

Named 86supersettings so it runs after userinit.sh if one exists.
I put some Led indicators in so you can tell if it ran right at boot up. (about all I did besides copy and paste) Thinking about adding some other stuff like repair ext, or some kind of log to help me see what happed... any suggestions.

OK, here's another Idea for another safety feature...
I would like to "hard code" a temp fail-safe in to the code. I would like to get rid of SetCPU and when OC-ing it's nice to have a temp failsafe.SHUTDOWN!LOL
Any way I guess I would just add a few lines to some existing script in my phone?.... Any suggestions.
Thanks for your time.

[KERNEL MOD] keytimer user setting script for mkasick Epic 4G keyboard patch

After having shared this on the #epic channel, I decided to share it here... This is for kernel devs who've incorporated mkasick's sysfs keyboard patch, located here.
This kernel mod and accompanying script are meant to be used in conjunction with mkasick's epic keyboard patch, and will perform the following:
1) Allow the kernel developer to easily choose the initial timer_delay value for the patch
2) Allow the end user to adjust the setting, and have it persist past boot
3) Checks user input for the setting, and not allow settings to occur that will make the keyboard unresponsive, or unusable
Files:
keytimer_initscript.sh
keytimer
Instructions for kernel devs:
1) Take the script inside keytimer_initscript.sh, and add it to your custom initscript called from init.rc
Note: place after the init.d section, or theimpaler747 script will overwrite the keytimer script.
2) Place the keytimer script inside your initramfs /sbin
Instructions for users:
1) Have a kernel with this mod inside, like mine:
DRockstar.Clean.Kernel.EC05.v1.02.zip
Note: Other kernel devs have this now, so it should come to your favorite kernel soon!
Also: If your current kernel has the mkasick sysfs keyboard patch, but not my kernel mod, you can take the keytimer script, and place it /system/xbin, and chmod 755 /system/xbin/keytimer. Without my kernel mod, the setting won't persist through a reboot, but it will give you an easy way to change the setting.
2) Open Connectbot or Android Terminal, and type su
3) type command: keytimer
it will show usage and the current value, the default is 7.
example use to change to theimpaler747 value of 5:
keytimer 5
Accepted values are 1 through 16.
The change will be immediate, and will persist after reboot.
Hope you all like this one, enjoy it!

Good job DRockstar ....This is saweet

good **** DRockstar....i already have it commited to my source for the next version
keep up the good work!

OK, links fixed, with code also posted.
Posted instructions for those who just want to use keytimer script, in case your favorite kernel doesn't have the keytimer mod installed yet, but has the keyboard patch installed.
Thanks to Rodderik for server space, after fossnet server got toasted.
Peace!

I'm pleased that folks are making good use of the sysfs patch, and making the user-side keytimer configuration much more approachable and useful. Thanks for doing this, it means a lot.

Sorry for asking this noob question but I just want to clarify. This is the stock Kernel with mkasicks fix to allow for the keyboard tweaks correct?
Nothing else is different about the kernel? If so, this is exactly what I was looking for.

Updated the kernel download to v1.02... which fixed some apps like metamorph not working with the location I set for busybox.
I need to make a post for the kernel now... sources are now posted at github.com/DRockstar.
to answer the previous question, yes, this kernel is intended to be a simple rooted kernel, based off samsung stock, with only simple mods ... its feature are:
* Root and busybox with minimal system mods
* designed to allow OTA update after flashing back the stock kernel
* mkasick sysfs keyboard patch, with my keytimer script
* voodoo sound 7 by supercurio, controlled by voodoo control app in android market
* additonal custom scripts in /sbin for cleaning root, busybox, and flash kernels and recoveries
This kernel was built to replace the traditional one click root method for my all in one root and recovery script.

ICS Transition Animations
A simple tutorial to get ICS transition animations on any ROM
Full credits to Capez only
Download APK Multi Tool (previously known as APK manager) from here
2) Extract with WinRAR, from the ROM you want to modify, the file framework-res.apk, that you can find in the directory \System\framework\.
3) Go to the apk manager folder and place the framework-res.apk file in the folder "place-apk-here-for-modding".
4) In the apk manager folder, double click on the file "Script". A cmd window will open.
5) Where it says "Please make your decision", write "22" (Set current project) and enter. Then enter "1" (to choose the first apk) and enter. Then enter "9" (Decompile apk) and enter.
The script will decompile the framework-res.apk.
6) Now go to your apk manager folder, go to Projects\framework-res.apk\res\anim\.
In this folder there are the animations of your rom. They consist in some .xml files decompiled.
7) Download this:
http://www.mediafire.com/?1qjwtotg1r8umm1
8) Copy the files from the folder "anims" of the zip downloaded into the anim folder and you are asked to replace the files; choose yes. Then copy also the files from the folder "other_files" to the anim folder.
9) Now go to your apk manager folder, go to Projects\framework-res.apk\res\values\. Edit the file integers.xml and put these two lines under the line of "shortAnimTime":
<integer name="config_activityShortDur">150</integer>
<integer name="config_activityDefaultDur">220</integer>
Save.
10) Return to Script. Enter "11" (Compile apk) and enter.
The script will rebuild the framework-res.apk.
11) You are asked if this is a system application. Enter "y" and enter. Then a second question appears. Enter newly "y".
12) Then after it processes, Don't press anything & DON'T CLOSE THIS WINDOW!!! A new folder "keep" is created in the apk manager folder. Go inside it and delete the file "resources.arsc". Now go inside keep\res\anim\ and delete every file with the same name as every file of the "anims" folder of the zip downloaded.
Then return to Script and press enter. It processes, then if everything went ok, in the folder "place-apk-here-for-modding" a file "unsignedframework-res.apk" is created. Copy it outside and rename it "framework_res.apk".
13) Now you can create a flashable zip or you can simply push it to your system (but you have to sign the apk).
CONGRATRULATIONS!!! YOU ARE DONE!!!

Swapping out PNG's in .apk
Full credits to itiskonrad
***Swapping out PNG's***
Okay, so say you have an icon or an image in your phone that you just don't like and would like to swap out with something (or swap out with nothing, so you can't see it at all). Here is what you'll need:
7zip for your computer
Root explorer for your phone
Some kind of image editor. I'm partial towards Paint.net. =) (Only if you're actually going to edit an image. If you're just going to swap it out for something else, you obviously won't need this.)
Here is a good example of something where I really felt like I needed to change some images we can use that I just discovered last night while calling to activate my credit card over the phone. Here is the dialer when you start the phone:
Notice those handy letters next to the numbers =)
Once I started the call to the credit card company, it asked me to verify myself by inputting, using the keypad, the letters of my mother's maiden name. So I opened the dialer, and what did I see?
For whatever STUPID STUPID REASON, they REMOVE the letters next to the numbers on the keypad that opens DURING the call, making it extremely difficult for me to type my mother's maiden name in the time permitted, given that no, I don't off the top of my head know where the letters sit on the dialer. So I felt this needed fixing =)
1.) Copy the apk you want to modify from your phone (using root explorer) and transfer to your computer
In this case, I wanted my Phone.apk, which is in /system/app. The vast majority of system apps are in this folder with the major exception of framework-res.apk, which is the phone’s BIG cajone in /system/framework, and as such, should be handled with utmost care. Messing with framework-res.apk incorrectly is an EASY way to brick your phone in a heartbeat.
2.) Unzip the apk using 7zip and look for your PNG's!
Keep the original, untouched, zipped apk somewhere safe on your computer. You’re going to need one to modify and another copy for safekeeping in case you want to revert back to the stock apk, or something goes wrong. Unzipping the apk just makes searching for the PNG you’re looking for much easier, since you can change the folder view in windows to give you a thumbnail of each of the items. And lookee, lookee, here they are in phone/res/drawable-hdpi, right next to other dial buttons with those handy letters!!
3.) Edit your PNG's however you want.
In this case, the work is pretty much done for us! I just swapped out the PNG's without the letters for copies of the ones with the letters, and just changed the names of the files to the original versions, like so:
4.) Using 7zip, right click on the original, untouched apk, choose 7zip, and open archive. DO NOT EXTRACT.
Open archive will let you explore the apk without having to extract it and lose the proper packaging of the apk.
5.) Select all your newly modified PNG’s and drag and drop them into the correct location in the open archive of the original apk, letting them overwrite the old PNG’s.
6.) Put this newly modified apk back onto your phone. Using root explorer, copy the new apk into the /system folder of your phone.
7.) CHANGE THE PERMISSIONS of the apk to match those of the original apk in /system/app.
In this case, long press on the phone.apk, select permissions, and select the check boxes as follows- Owner: Read, Write; Group: Read; Others: Read. This matches the permissions of phone.apk in /system/app
8.) Move the new apk into /system/app, and let it overwrite the original!
9.) Restart your phone!
Voila! Now when I call my credit card company and have to type in names, I can!

I thought it is useful to kept all of them in one place.
But based on your response if you feel it is not necessary and the Mod also feeling the same, Please delete this thread.
I don't mind.

I think this thread is very useful and i will surely subscribe and use this thread in the future

Thank you very much for your support. But lets wait for the MOD's reply.

Just to help your argument, there's a collection of ROM's so why not a collection of tweaks

yup... make a master index of tweaks
and we can apply only those we want separately ..great idea !

Regarding your battery problem (seen in your signature)
Me too faced battery problem. But at first I thought it is an issue with firmware or problem with out G3 itself. But after getting it replaced by Samsung Service Centre it gives huge battery backup, of course with Custom ROMs only.

+1 for this topic. Great job!

Good work! But Jazux shouldn't be given any credits for these, it was knzo who repo'ed it ... Jazux did nothing!

Yeah i can see that lol

Just used some of these tweaks on stock XXJPS (only the ones i found useful for me). I will see the result

plz delete jazux from credits, because he had opened similar thread long back which he had copied from other thread and didnt even care to give that guy credits..so i think jazux doesnt deserve those credits

[REF][DEV] Tweaks for i9003 list [UPDATE]

This is a list of all threads avaiable to our phone, using for ROM developer too...
i decided to post in general, becouse this is not developer threads, developer threads are done from developers and i'm a human no developer.
Adrenaline Shot v14 Universal ​What do these tweaks do?
the first improve is under /system/bin, replace 2 bin with leaked from ICS 4.0 , with GREAT EPIC improvement , 2 bins 're app_process and system_server.
app_process executes, and executes a runtime environment for a dalvik class
The system server is the core of the Android system and as described in the boot sequence post it is started as soon as Dalvik is initialized and running.
like all tweaks , this will add some /system/etc/init.d script , if kernel supports of curse
( for everyone using Gentoo, know init.d too )
the first one is 00remount
Code:
#!/system/bin/sh
#Partition mounts by Dsexton702
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /system /system
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /cache /cache
mount -o remount,noatime,nodiratime,delalloc,noauto_da_alloc,barrier=0 /data /data
This script will (re) mount the EXT4 partitions with some "tweaks", like noatime, nodiratime,delalloc and soso.. , speed increased in R/W
the second is 01kerneltweak
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_GENTLE_FAIR_SLEEPERS > /sys/kernel/debug/sched_features
unmount /sys/kernel/debug
using NO_GENTLE_FAIR_SLEEPERS as schedule features, nothing to hard
the third 02journaling
provide to delete cache if its too big
the 4th is 03sysctl
Code:
#!/system/bin/sh
sysctl -p
This is simply call to sysctl ( parameters settings under linux kernel ), its under kernel tweak
the 5th is 04sysctltweaks
this will set a lot of utils things about kernel and its driver ( like governor ) , if people using ondemand it will set ondemand/up_threshold to 65 ( more responsive , but increase battery drain ) and ondemand/sampling_rate to 30000 ^^
05sdcardspeedfix
fixing READ_AHEAD_KB , suggest it will increase sdcard speed ( not too much )
06zipalign
provide to zipalign all /data/app/*.apk files, anything know to apk files are zip archive contains a lot of things, zipalign optimize this archive , major info at developer.android.com/guide/developing/tools/zipalign.html
07vacuum
this provide to "VACUUM" all *.db ( see SMS's DB, etc ... ) to rebuild all *.db better, increase performance too!
08ramscript
i never will use this, this is not designed for our phone IMHO it can be replace with superchanger ( see after )
/system/lib/libsqlite*
will replace sqlite's lib for better performance, sqlite has sync and async method, this will disable sync , theorically it will double the performance in I/O
/system/xbin
it simply provide a sqlite3 bin and zipalign bin, nothing tweaks
Click to expand...
Click to collapse
Thunderbolt tweaks ( this is not avaiable, i upload some script i've download a time ago )​/system/etc/init.d
s78enable_touchscreen_1
Code:
#!/system/bin/sh
#Touchscreen
#Configure touchscreen sensitivity
#Sensitive(Chainfire)
echo 7035 > /sys/class/touch/switch/set_touchscreen;
echo 8002 > /sys/class/touch/switch/set_touchscreen;
echo 11000 > /sys/class/touch/switch/set_touchscreen;
echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
this is IMHO the best script i've ever seen , this will increase sensitivity of touchscreen
07sqlite_optimize
this will vacuum and re-index all db, better than Adrenaline's 07vacuum IMHO
S70darky_zipalign
Another zipalign script, useless
*bolt_siray*
this is not developer for our phone, this will working only with adeguate kernel ( we haven't )
S98CFS
it will provide a lot of tweaks using sysctl and kernel proc/ interface
S98system_tweaks
this is a lot of script unify in one script
i edit this to be "better" with our phone, i delete re-mount runtime , adrenaline's 00remount do it better
and modify this part:
Code:
# ==============================================================
# smartassV2
# ==============================================================
if [ -e /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq ]; then
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq;
if [ "`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq`" -eq 300000 ]; then
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
else
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
fi;
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_wakeup_freq;
echo "85" > /sys/devices/system/cpu/cpufreq/smartass/max_cpu_load;
echo "75" > /sys/devices/system/cpu/cpufreq/smartass/min_cpu_load;
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/ramp_down_step;
echo "0" > /sys/devices/system/cpu/cpufreq/smartass/ramp_up_step;
fi;

THIS IS THE ONLY MEMORY Manager, this provide a better ram manager by android, anyone know that Random Access Memory contains a kernel and all APP run, kernel are loaded in lowest address possible , and all app are loaded when open, android usually doesn't close this, for better speed when you re-open its, but if you have small RAM ( 512 MB too ) this will cause a lot of problem , superchange fix it!
i suggest to use 512HP Balanced ( or Performance ) with Bulletproof launcher + OOM FIX, Nullify lag work too
HOW INCLUDE THIS INTO MY ROM?
Poseidons ROM include this by ****ty init.d script, i suggest to delete and re-apply
if you are not ROM Developer is simple, download latest avaiable by link i provide at top and with ROOT-enabled ( check su ) and Script Manager ( or terminal emulator -> # su -> sh script_location ) follow the scripts guide, remember, using this can cause ( 0.01% ) bootloops, i suggest to use local.prop and init.rc integration
if you are a ROM Developer is more complicated than simple user, for stick you can use:
init.d script ( like poseidons )
local.prop and init.local.rc ( suggest ) under /data
build.prop
init.d script ( i do not see this, for me is the worst way to get it )
init.local.rc:
create a /data/init.local.rc contains

i9003 tweaks​
01loopy
this will make phone more smoothness by renice ( change priority ) the main process will run
i suggest to set your launcher process here like:
Code:
### Launcher apps ###
renice -19 `pidof com.sec.android.app.twlauncher` # TouchWiz Launcher
renice -19 `pidof org.adwfreak.launcher` # ADW Launcher Ex
renice -19 `pidof org.zeam.core` # Zeam launcher
renice -19 `pidof info.tikusoft.launcher7`# Launcher 7

PART2
95allinone
This will provide a complete collection of tweaks avaiable, i hate this becouse, a lot of tweaks here are not implemented correctly , like:
Code:
#Part below here edited by me (changed values) Credits to Juwe11
if [ -e /sys/module/lowmemorykiller/parameters/adj ]; then
echo "0,1,2,4,6,15" > /sys/module/lowmemorykiller/parameters/adj
fi
if [ -e /sys/module/lowmemorykiller/parameters/minfree ]; then
echo "2560,4096,5632,10240,11776,14848" > /sys/module/lowmemorykiller/parameters/minfree
fi
if [ -e /proc/sys/vm/swappiness ]; then
echo "20" > /proc/sys/vm/swappiness
fi
zOOM zOOM :
Code:
echo "2560,4096,5632,10240,11776,14848" > /sys/module/lowmemorykiller/parameters/minfree
This is the same things that do superchanger, but this will be wrost for our phone IMHO
Code:
echo "20" > /proc/sys/vm/swappiness
the right value ( in my cases ) is 0, i haven't swap of anyway we dont have to have a swap!
Zipalign Runtime, it will just implemented by a lot of script, this is also the wrost IMHO zip align script i've never seen
Code:
for k in $(busybox mount | grep relatime | cut -d " " -f3) ; do
sync;
busybox mount -o remount,noatime $k;
done;
this will break 00remount script
Code:
for i in /sys/block/*/queue/scheduler ; do
echo "noop" > $i;
done;
if kernel support i suggest deadline
Code:
# Tweak kernel VM management
echo 0 > /proc/sys/vm/swappiness
echo 10 > /proc/sys/vm/dirty_ratio
echo 4096 > /proc/sys/vm/min_free_kbytes
??? WHAT? again?
Code:
echo "interactive" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "cfq" > /sys/block/mmcblk0/queue/scheduler
see upper
Code:
echo "deadline" > /sys/block/mmcblk0/queue/scheduler
What? another change?
this is good:
Code:
# Copyright @ CRANIUM ROM

#End Cranium Tweaks
Conclusion: 95allinone is simply a addiction of all tweaks avaiable in one script without any review and improves for our phone ( in this case, this work ), this will only increase the boot time and break others tweaks installed ( some )
99V6_Superchanger
DO NOT USE THIS, THIS IS EPIC FAIL INIT.D SCRIPT!
Code:
mount -o remount,rw /system
mount -o remount,rw /dev/block/mtdblock3 /system
mount -o remount,rw /dev/block/mtdblock6 /system
*facepalm*
in my terminal:
Code:
# su
# ls -la /dev/block/mtd*
ls: /dev/block/mtd*: No such file or directory
anyway this is not init.d script, this is v6 script , this is not compatible with init.d ,

WHICH GOVERNOR DO U USE?​( ref: Simba501 )
SEE THIS
Anyway i suggest:
- Smartassv2 if you want performance over less battery
- InteractiveX if you want battery over less performance
CAN ANY KERNEL DEVELOPER INCLUDE LULZACTIVE CPUFREQ-DRIVER IN OUR KERNELS? ITS THE PERFECT GOVERNOR , EITHER FOR BATTERY AND PERFORMANCE
EGL TWEAK!​Android header said:
Code:
#
# One line per configuration, of the form:
#
# D I TAG
#
# D: display (0: default)
# I: implementation (0: software, 1: hardware)
# TAG: a unique tag
#
# The library name loaded by EGL is constructed as (in that order):
#
# /system/lib/egl/libGLES_$TAG.so
# /system/lib/egl/lib{EGL|GLESv1_CM|GLESv2}_$TAG.so
#
in the stock ROM the egl.cfg is:
Code:
0 0 android
0 1 POWERVR_SGX530_125
what's meaning?
simply using cpu ( with gpu too ) to render all apps and system
if you modify to:
Code:
0 1 POWERVR_SGX530_125
it will use overall GPU render only, more fast and imho better Battery life because, CPU in our cases with overclock consume more than GPU

Wow!! very good thread!! I am setting up a custom rom, could u tell me what of these could give my rom a better battery life? Thank u man!

Battery life is influence by:
Running Apps
Governors do you use
Memory Manager ( #1 addicted )
If you set /etc/init.d script to set conservative governor and implemented v6 without any stupid app like facebook or bloatware samsung, and your battery seems infinite
in the past i used SCH Rom , its used only v6 and most important tweaks , without any stupid bloatware, battery seems very infinite ^^ like 2% in 5 hours under 2G network

Ok, sorry for my noob question but I am learning a lot of things this days.. where can I find a tutorial about how to set a governor or a frecuency by default in my kernel? Thank u very much

I'm noob too
for frequency are too kernel releated to be generalized,
or if you using XDA_Bam kernel
39frequency
Code:
#!/system/bin/sh
echo "300" > /sys/power/overclock_opp1
echo "600" > /sys/power/overclock_opp2
echo "800" > /sys/power/overclock_opp3
echo "1000" > /sys/power/overclock_opp4
anyway you can create init.d script like
40governorbattery
with:
Code:
#!/system/bin/sh
echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
and see if it stick ^^

Hi.
Are there codes that can remove or dissable the TouchUI aka TouchWiz interface on the i9003 and just use the android deffult launcher?
Another thing something that will easy-up my ram usage and allow more usable ram?
If so how do i implement them?

I just want to add a cool sound and audio tweaks using MagaBassBeats_Mod
First download the MagaBassBeats_Mod_9003.zip file from the xda forum.
Now copy it to the sdcard.
Reboot to the recovery mode.
Now select install from zip file and chose internal sdcard.
Search for the zip file, hit power button, and chose yes.
That's it now you can enjoy a great sound quality.

[GUIDE][TUT] Learn basic scripting, how to execute scripts, mod building

Hello guys, I want to share my expirience with users who wants to learn basic scripting stuff, busybox commands, how to use them, how to execute them, how to make .sh files.
Ok, let's start!!! ​
First we must to learn what is busybox. BusyBox is software that provides several stripped-down Unix tools in a single executable file. It runs in a variety of POSIX environments such as Linux, Android.
Busybox allows you or programs to perform actions on your phone using Linux (copied from Unix) commands. Android is basically a specialized Linux OS with a Java compatible (Dalvik) machine for running programs. The Android kernel is a modified version of the Linux kernel (that is why the Android kernel must always be open source). Busybox gives functionality to your phone that it does not have without it. Many programs, especially root programs such as Titanium Backup, require busybox to perform the functions of the program. Without busybox installed your phone is much more limited in what it can do.

}
Here is some info about busybox, you can track here release dates, you can download sources...
http://spblinux.de/2.0/doc/commands.html
Also here is busybox installer for our "linux devices" heheh ^~^ by stericson. You have two versions of it as you see paid and free.
Chose paid if you want to donate him for awesome job.
Free:
https://play.google.com/store/apps/details?id=stericson.busybox
Paid(PRO):
https://play.google.com/store/apps/details?id=stericson.busybox.donate
After that you need Terminal app, you can download it from playstore too.
Link: Download it from here
This app emulates Linux terminal, with it you can access to android shell.
Lets's start with learning basic terminal stuff
The most of shell commands doesn't need root access, but some of them are need it.
To give root access to the terminal app, you need to type next.
Code:
su [I](press enter)[/I]
After pressing enter, another window will popup to grant root access. Tap on GRANT
***When you typing something into the terminal window, take care because EVERYTHING IS CASE SENSITIVE.***
We all know there are three permissions per group on a file read,write,execute or rwx.
To set permissions as rw-r--r-- we use chmod 644 or 0644 but most don't know why ? Here's why
Read or r has a positional weight of 4, Write or w has 2 and Execute or x has 1. Add them up for each group and you'll get the chmod number to use. For above example, the numbers will be (4+2)(4)(4) i.e. 644 or if you want four digits, use 0644 and that's pretty much it. It comes in very handy if you're learning shell scripting because Linux revolves around permissions. (Thanks to @MSF Jarvis)
Let's go trough basic shell commands. ​
If you interested about all commands, you can check them HERE.
cat [file destination] - use this command to print everything from a file to the terminal window
Example:
Open terminal window, and type next:
Code:
busybox cat /proc/meminfo [I](press enter)[/I]
You will get output after pressing enter
Now, you can see here, if you open any file manager and go to destination which was given for example "/proc/meminfo"
You will see next file and stuff inside it
Heheh, is it same?? ^~^ for sure that it is, you can use it for any file on your device which have text in it.
Let's go to the next basic command ^~^
echo - this command can be used for printing arguments to stdout. Also you can use it for adding text in already existing file which we need here, because we are learning scripting stuff, right? ^~^
Example:
Open terminal window, and type next:
Code:
busybox echo "Scripting is awesome" > /sdcard/test [I](press enter)[/I]
Ok, let's explain this.
First you added a command echo to add something in existing file, then between "..." we need to put arguments, for our case this is "Scripting is awesome" next we see symbol " > " which will forward arguments to next added direction, in our case this is "/sdcard/test".
First we need to have a existing file (IMPORTANT)
After we agreed with that we have a file
Open terminal as I already explained and after pressing enter you will get output on the terminal window.
That is a file from our /sdcard/
Don't delete this file, we will use it later with " sh" command.
Let's go to the next basic command
clear - Use this comand to clear whole terminal window.
Example:
You have a terminal window which have a lot of stuff on it, for example stuff from previous lines, text, etc.
You can simply make it blank with just one command
Code:
busybox clear [I](then press enter)[/I]
And voila, terminal window is blank
touch [file destination] - Use this command to create a blank file on any destination on your android device.
Example:
Open terminal window, and type next:
Code:
busybox touch /sdcard/scripting_007 [I](press enter)[/I]
This will create file called "scripting_007" on "/sdcard/" in this case, you can put any.
As you can see file "scripting_007" exist on /sdcard/
mkdir [file destination] - Use this command to create one empty folder on any destination on your android device.
Example:
Open terminal window, and type next:
Code:
busybox mkdir /sdcard/development [I](press enter)[/I]
This will create folder called "development" on "/sdcard/" in this case, you can put any.
sh [path of a file] - Use this command to execute basic script
Example:
Open terminal window, and type next:
Code:
sh /sdcard/test [I](press enter)[/I]
This will execute file which you make before with "echo" command
sleep [time in secs] - Use this command to make an offset between executing lines inside script.
Example:
Open terminal window, and type next:
Code:
busybox echo "Scripting is"
busybox sleep 10
busybox echo "awesome"
This is a combination of two commands as you can see, echo and sleep.
After launching this simple script in terminal window you will get first "Scripting is" and after 10 secs you will get awesome.
rm [ -f (file) -rf (folder)] - this is a command for removing files (-f) and folders (-rf)
Example:
Create a file called "android" on sdcard, then open terminal window, and type next:
Code:
busybox rm -f /sdcard/android
This simple code will remove a file called android from sdcard.
Now do the same thing with a folder, create one with the name "android" and run terminal emulator
Code:
busybox rm -rf /sdcard/android
This will remove folder called android from your sdcard.
Now, let's go with some advanced stuff​
You need any text editor, I suggesting this one
Link: Download from here
Now, open the app and write a new file and give it a name "test1"
Inside a file write next text:
Code:
busybox echo "Android"
busybox sleep 2
busybox echo "is"
busybox sleep 2
busybox echo "Awesome"
Save the file and copy it to some location, i suggest /sdcard/.
Open up terminal emulator and type next
Code:
sh /sdcard/test1 [I](press enter)[/I]
This thing will execute your script with the name test1 from /sdcard/.
Output will be "Android", then after two seconds will appear "is" and then after two more seconds "Awesome" will appear. THATS IT!!! You learned how to make a file (script) and how to execute it with terminal emulator.
Now do the same thing make a file with the name "test2" and make another file with a name "print"
First open "test1" and write next:
Code:
busybox echo "After 5 seconds"
busybox sleep 1
busybox echo "You will get a suprice"
busybox sleep 2
busybox clear
busybox echo "1"
busybox sleep 1
busybox clear
busubox echo "2"
busybox sleep 1
busybox clear
busybox echo "3"
busybox sleep 1
busybox clear
busybox echo "4"
busybox sleep 1
busybox clear
busybox echo "5"
busybox sleep 1
busybox clear
sh /sdcard/print
I think that you already know whats happened here
You have print, then you have sleep to make offset, and after that you have clear command to make window blank
Now open file with the name "print"
Inside it write next:
Code:
busybox echo "Voila, suprise"
Save this file, and open terminal emulator, and write next:
Code:
sh /sdcard/test2
And magic happens
In this example you learned how to execute second file with first, I think that it's not difficult for you
In this example we will play a bit with colors outputs
Codes for colors are below
Code:
busybox echo -e " 1. Black \e[0;100m \e[00;37;40m"
busybox echo -e " 2. Red \e[0;101m \e[00;37;40m"
busybox echo -e " 3. Green \e[0;102m \e[00;37;40m"
busybox echo -e " 4. Yellow \e[0;103m \e[00;37;40m"
busybox echo -e " 5. Blue \e[0;104m \e[00;37;40m"
busybox echo -e " 6. Purple \e[0;105m \e[00;37;40m"
busybox echo -e " 7. Cyan \e[0;106m \e[00;37;40m"
busybox echo -e " 8. White \e[0;107m \e[00;37;40m"
Try to copy this into terminal window and see what will happened or try whing which you learned before with the executing files. Copy whole code to a file and execute it with "sh" command. USE YOUR KNOWLEDGE.
Here you can see all things based on bash script coloring
https://wiki.archlinux.org/index.php/Color_Bash_Prompt
or
http://misc.flogisoft.com/bash/tip_colors_and_formatting
Here you can see all codes and it's nice descirbed.
Now, let's start
Make a file with the name "test3" open it and write or copy next code inside:
Code:
busybox echo " .... "
busybox echo " / / "
busybox echo " / / "
busybox echo " / / "
busybox echo " / /_._._. "
busybox echo -e " /_._._._._./ \e[00;41m SPEED MOD \e[00;37;40m v3.0"
busybox echo "*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*"
busybox echo -e "\e[01;32m Feel smoothness \e[00;37m"
busybox echo " "
As you can see this part was taken from mine L Speed performance/battery mod
Save the file, open terminal and type inside
Code:
sh /sdcard/test3
And you will get the same screen like in first L Speed menu.
Let's play a bit with this
You see the code
Code:
\e[00;41m SPEED MOD \e[00;37;40m v3.0
Just change one number instead of 41 write 42 and you will get green color, then give a try to other nubers. Every number is another color for example:
Code:
# Reset
Color_Off='\e[0m' # Text Reset
# Regular Colors
Black='\e[0;30m' # Black
Red='\e[0;31m' # Red
Green='\e[0;32m' # Green
Yellow='\e[0;33m' # Yellow
Blue='\e[0;34m' # Blue

On the next phase we will learn how to use variables, in bash scripts this is simple, just add a simple "tag" then what you want to connext wit this tag.
Here is an example:
Code:
file=/sdcard/test4
busybox touch $file
Ok, here is one simple thing, this is same like in touch command explaining, but there is a little difference. We added variable or you can call it shortcut if it's easier for you.
To call variable somewhere in a file you need to use a dollar sign "$" then name of your variable. Let's to next examole with variables.
As we now have file called test4 on our SD, we can go trough.
Code:
file=/sdcard/test4
busybox echo "hey file" > $file
As you can see everything is repeating from previous examples just with variable. This is much easier, and you will save a bit of time.
Now we can see what is inside file Open terminal emulator and type next
Code:
busybox cat /sdcard/test4
And you will get output "hey file"
Simple isn't it?
In this part we will learn how to use if, elif, else It's pretty simple, let's start.
Pattern for this will be:
Code:
if [what]; then
do something
fi
if [what]; then
do something
elif [what if not "if"]
do something
else
what to do else
fi
Ok what we have here?
The first part of code show us simple code which mean if for example something is true then do something and then close if with fi.
Second part of code is a bit "complicated". If somethig is true then do something, then we have elif, in case that if is false then it will do what is under elif. In case that both of them are false, everything what is under else will be executed.
Ok here is an example:
Code:
if [ -e /sdcard/test5 ]; then
busybox echo "hello" > /sdcard/test5
else
busybox touch /sdcard/test5
busybox echo "hello" > /sdcard/test5
fi
Ok, if file test 5 exists add hello to it, else(if not) then create a file and add text hello in it.
Another example with a bit of complications heheh
Code:
if [ -e /sdcard/test5 ]; then
busybox echo "file 5 exists"
elif [ -e /sdcard/test6 ]; then
busybox echo "file 6 exists"
else
busybox echo "files are not exist"
fi
Ok, here is explanation, if test5 exist then print "file 5 exists" going to the next line, if file test6 exist pri t "file 6 exists" and else if both of them doesn't exist print "files are not exist".

Everyone who knows a bit of the performance/battery mods wants sometime to learn what is inside and how it's working
Here is a guide by @Paget96 (me) ^~^
As we know for every mod we need root, this is needed because we must to access to android shell.
init.d support, that is a folder which launch files from it on every boot. Init.d is included on some ROM's by default, but on some you need yo enable it by default(I will explain later how).
Next thing what you need is for sure busybox. And a little bit of free space on the /system partition.
Everyone knows how to root, I don't need to explain how to do that right?
User who doesn't have init.d will make it with next steps.
1. Flash superSU by @Chainfire (IMPORTANT)
2. In /system/etc/ make a file with the name "install-recovery-2.sh and push next code in it
Code:
#!/system/bin/sh
/system/bin/sysinit
3. Inside system/bin make a file with the name " sysinit" and push next code in it
Code:
#!/system/bin/sh
busybox sleep 30
export PATH=/sbin:/system/sbin:/system/bin:/system/xbin
run-parts /system/etc/init.d
4. Open /system/etc and make folder with the name "init.d"
Now you need to set permissions for all of this files.
Open terminal emulator and do next:
Code:
su
This will give root access
Code:
busybox chmod 755 /system/etc/install-recovery-2.sh
busybox chown 0.2000 /system/etc/install-recovery-2.sh
With this you will set "executable" permissions.
And we need permission for sysinit
Code:
busybox chmod 755 /system/bin/sysinit
busybox chown 0.2000 /system/bin/sysinit
And that's it
To install busybox use app "busybox installer" by stericson from playstore.
***IMPORTANT*** Don't change too much things, because you will get crap in your hands
Tools which are needed is
Text editor, I suggest Turbo Editor
Terminal emulator
ES file explorer
Ok, let's start
We will start with virtual memory tweaking...
Open file manager and create one folder where you will build a mod.
Inside it we will create one file for beginning and call it "00sysmod"
Code:
#!/system/bin/sh
busybox chmod 644 /proc/sys/vm/*
busybox sysctl -e -w vm.dirty_background_ratio=3
busybox sysctl -e -w vm.dirty_ratio=15
busybox sysctl -e -w vm.swappiness=40
busybox sysctl -e -w vm.dirty_expire_centisecs=500
busybox sysctl -e -w vm.dirty_writeback_centisecs=3000
busybox sysctl -e -w vm.min_free_kbytes=4096
busybox sysctl -e -w vm.overcommit_memory=1
busybox sysctl -e -w vm.overcommit_ratio=75
busybox sysctl -e -w vm.page-cluster=0
busybox sysctl -e -w vm.panic_on_oom=0
Copy this inside file, save it and copy to init.d folder
After that set permissions to 755
Code:
busybox chmod 755 /system/etc/init.d/00sysmod
Let's explain every line:
First line is a header of every script.
Next line will change permissions (in this case read, write, read, read) of a files which are inside /proc/sys/vm/*. * means every file.
Everything below it are vm parameters.
vm.dirty_background_ratio
Contains, as a percentage of total available memory that contains free pages
and reclaimable pages, the number of pages at which the background kernel
flusher threads will start writing out dirty data.
The total avaiable memory is not equal to total system memory.
dirty_ratio
Contains, as a percentage of total available memory that contains free pages
and reclaimable pages, the number of pages at which a process which is
generating disk writes will itself start writing out dirty data.
The total avaiable memory is not equal to total system memory.
swappiness
This control is used to define how aggressive the kernel will swap
memory pages. Higher values will increase agressiveness, lower values
decrease the amount of swap. A value of 0 instructs the kernel not to
initiate swap until the amount of free and file-backed pages is less
than the high water mark in a zone.
The default value is 60.
dirty_expire_centisecs
This tunable is used to define when dirty data is old enough to be eligible
for writeout by the kernel flusher threads. It is expressed in 100'ths
of a second. Data which has been dirty in-memory for longer than this
interval will be written out next time a flusher thread wakes up.
dirty_writeback_centisecs
The kernel flusher threads will periodically wake up and write `old' data
out to disk. This tunable expresses the interval between those wakeups, in
100'ths of a second.
Setting this to zero disables periodic writeback altogether.
min_free_kbytes
This is used to force the Linux VM to keep a minimum number
of kilobytes free. The VM uses this number to compute a
watermark[WMARK_MIN] value for each lowmem zone in the system.
Each lowmem zone gets a number of reserved free pages based
proportionally on its size.
Some minimal amount of memory is needed to satisfy PF_MEMALLOC
allocations; if you set this to lower than 1024KB, your system will
become subtly broken, and prone to deadlock under high loads.
Setting this too high will OOM your machine instantly.
overcommit_memory
This value contains a flag that enables memory overcommitment.
When this flag is 0, the kernel attempts to estimate the amount
of free memory left when userspace requests more memory.
When this flag is 1, the kernel pretends there is always enough
memory until it actually runs out.
When this flag is 2, the kernel uses a "never overcommit"
policy that attempts to prevent any overcommit of memory.
Note that user_reserve_kbytes affects this policy.
DON'T CHANGE THIS VALUE, YOU WILL GET CRAP IN A HANDS, THIS IS JUST FOR INFO
overcommit_ratio
With this parameter you will set how much space will allocations use in physical RAM. (Percentage)
page-cluster
page-cluster controls the number of pages up to which consecutive pages
are read in from swap in a single attempt. This is the swap counterpart
to page cache readahead.
The mentioned consecutivity is not in terms of virtual/physical addresses,
but consecutive on swap space - that means they were swapped out together.
It is a logarithmic value - setting it to zero means "1 page", setting
it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
Zero disables swap readahead completely.
panic_on_oom
This enables or disables panic on out-of-memory feature.
If this is set to 0, the kernel will kill some rogue process,
called oom_killer. Usually, oom_killer can kill rogue processes and
system will survive.
If this is set to 1, the kernel panics when out-of-memory happens.
If this is set to 2, the kernel panics compulsorily even on the
above-mentioned. Even oom happens under memory cgroup, the whole
system panics
In this part we will tweak kernel parameters
Open file manager as before and create a file with the name " 00kerneltweak"
Here we will use if statement, just for a little practise ^~^
Code:
if [ -e /proc/sys/kernel/shmmni ]; then
busybox echo "2048" > /proc/sys/kernel/shmmni
fi
if [ -e /proc/sys/kernel/shmall ]; then
busybox echo "1572864" > /proc/sys/kernel/shmall
fi
if [ -e /proc/sys/kernel/shmmax ]; then
busybox echo "33554432" > /proc/sys/kernel/shmmax
fi
if [ -e /proc/sys/kernel/msgmni ]; then
busybox echo "512" > /proc/sys/kernel/msgmni
fi
if [ -e /proc/sys/kernel/msgmnb ]; then
busybox echo "16384" > /proc/sys/kernel/msgmnb
fi
if [ -e /proc/sys/kernel/msgmax ]; then
busybox echo "8192" > /proc/sys/kernel/msgmax
fi
Copy this inside file, save it and copy to init.d folder
After that set permissions to 755
Code:
busybox chmod 755 /system/etc/init.d/00kerneltweak
Same as we learned before if file exist then do next
Let's explain this parameters:
shmall
The total amount of shared memory (in pages) which can be allocated on the system
shmmax
The maximum size of a shared memory segment (in pages)
shmmni
The maximum number of shared memory segments available on the system
msgmni
The number of IPC message queue resources allowed (by default, 16).
msgmnb
Defines the maximum size in bytes of a single message queue. The default value is 65536 bytes.
msgmax
The maxim...

Remove Google Play Services data
Code:
#!/system/bin/sh
mount -o remount,rw /data
busybox mount -o remount,rw /data
GSM=/data/data/com.google.android.gms
for i in $GSM
do
busybox rm -rf $i/*
done
make a file, and add this inside, like before
copy to /system/etc/init.d
set permissions to 755
Clear browser data
Code:
#!/system/bin/sh
mount -o remount,rw /data
busybox mount -o remount,rw /data
browser=/data/data/com.android.NAME_OF_THE_BROWSER
for i in $browser
do
busybox rm -rf $i/*
done
make a file, and add this inside, like before
copy to /system/etc/init.d
set permissions to 755
first write a name of the browser, some devices have chrome as a default, then name will be
com.android.chrome
I'm sure that its
com.android.browser for default one
Check that inside /data/data, then just change inside the script
Or you can use this package
Code:
#!/system/bin/sh
while true; do
mount -o remount,rw /data
busybox mount -o remount,rw /data
busybox echo -n "Enter a name of the browser: "
busybox read -r name
brw=/data/data/com.android.$name
if [ -d $brw ]; then
for i in $brw
do
busybox rm -rf $i/*
done
busybox echo "Clearing done"
busybox sleep 2
else
busybox echo "Browser doesn't exist, please type another one..."
busybox sleep 3
fi
done
Well, this for this file guide is different,
Call the file "ccleaner" copy it to /system/bin
Set permissions to 755 like before
Open terminal emulator
Code:
su
ccleaner

Borked means I changed my recovery and flashed a GB ROM instead of using my friends custom built CM 11 build. My trusty Tahr system also broke down, but I am resilient so I'll manage and you WILL see the screenshots before 5PM IST.[emoji16] [emoji16] [emoji16] [emoji6] [emoji6] [emoji6] [emoji6]
