[TWEAKS][SCRIPTS] Collection of 'em all - build.prop; init.d; etc.

On my ROMs adventure I've been collecting some tweaks and scripts and seems to me it's now time to share it. While some values in terms of optimization might fluctuate from device to device, I've found these pretty consistent throughout many.

Init.d
(needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)
1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;

5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files

for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
[url]http://forum.xda-developers.com/showthread.php?t=860586[/url]
13. Loopy Smoothness tweak
Code:
[url]http://forum.xda-developers.com/showthread.php?t=1137554[/url]
[url]http://forum.xda-developers.com/showthread.php?t=1205744[/url]
14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
16. OOM groupings and priorities tweaks - SuperCharger
Code:
[url]http://forum.xda-developers.com/showthread.php?t=991276[/url]
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
Alright, I think this is it for now.
If you have any other tweaks or better values, you can PM me and I'll include them.

Wow... Neojn, will tis work on lg optimus one? I know u used to have a optimus one...

my word thats a MASSIVE list lol thanks, some interesting tweaks there
Sent from my HTC Desire using XDA App

If I have time in the future I can create a script that applies them all.
(with a check of already existing tweaks / compatibility with the device, etc)

If some script fail it may cause bootloop? And can use for all device?
thanks for answer.

None of them should cause bootloop, at least if you follow everything I wrote.
Yes, they work on most devices. Just read what it needs.

how do i test this one because i cant remember what i rename the bold parts to lol
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
thanks in advanced
Eoghan

I hav another question..What is "Flags"?
- 18. Miscellaneous flags
- 7. Flags blocks as non-rotational and increases cache size
thanks for answer

It's like it says, you need the /dev/block/ path to system, data and cache partitions.
And they need to be formatted to ext4 of course.
This varies from device to device, whether it is emmc or mtd.
Running the command "mount" should give you the answer for both.

As a noun it's like a property, as a verb is like defining.
Either way, I think I may have some time during next week to make a script to deploy these tweaks on most ROMs.

thanks ya knzo.

thanks . If you have time it would be awesome if you make a zip that can be flashed to CWM

I need a little help creating the script files. I dont need all of these tweaks. So, I need instructions on how to create the file with only what I need.
Can I create just one script file for all the tweaks or do they have to be seperate?

If you don't know how to apply them just install a rom that surely has some of them

Nice list.
I think ro.ril.disable.power.collapse should read
Code:
ro.ril.disable.power.collapse=0
because you want the power collapse to happen to save energy. Also, all commands should be lower case. Therefore it should be
Code:
debug.performance.tuning=1
video.accelerate.hw=1
with 'd' and 'v' instead of 'D' and 'V' at the beginning.
Further, I use
Code:
dalvik.vm.startheapsize=4m
which in my experience reduces RAM usage by approx. 15 MB on startup.

Nice list.
I think ro.ril.disable.power.collapse should read
Code:
ro.ril.disable.power.collapse=0
because you want the power collapse to happen to save energy. Also, all commands should be lower case. Therefore it should be
Code:
debug.performance.tuning=1
video.accelerate.hw=1
with 'd' and 'v' instead of 'D' and 'V' at the beginning.
Further, I use
Code:
dalvik.vm.startheapsize=4m
which in my experience reduces RAM usage by approx. 15 MB on startup.

ro.ril.disable.power.collapse should be 1 to disable the power collapse

in that link it is written

The sense says it should be=1, so what do we use?
Another thing, we can't use all the build.prop lines of that link is this right?

Just use the tweaks currently in the OP. I believe thefrankenstein will only state the tweaks that work.

I'd changed the media builds yesterday, however, now i can't playing youtube's videos because when i press play button the Mobile become frigde and i only can to turn off pressing long the power button.
Can you give me thr factory status? I didn't a back up file :s

When you edit build.prop, the phone automatically saves a build.prop.bak in the same location, just under your build.prop. Just rename it to build.prop and delete the bad one.

[Q] Faux kernel init.post_boot.sh customization

This is, i´m reeally noob, and do it just for fun and have muy sensation the way I like, so I want to know just the basics to do that.
Just added stock frequencies to init.post_boot.sh of faux kernel, and I wondering, how to control the transitions or steps of the frecuency scaling, I found this lines, but really don´t know if they will work. Some of them are already in my file. But I don´t know whats the function of sampling_rate, up_threshold, and sampling_down_factor, and if they will work on intellidemand governor.

thanks! this is great. Can you also add snake charmer=on?

As per my findings, snake charmer is Faux's application thingy. But I will definitely take a look.

Has established, but my options which were before application Faux123 Kernel Tweaks have not changed.

Glad to see you here!!

Thanks

The app costs $4.99, which is kind of pricy.

dont think his going to be very happy when he sees this lol

Heh $4.99 is nothing for what our devs do for us

i personally bought all of his apps even though i don't use them all, devs need support, threads like are kind of inappropriate and unfair.

Excuse me? In what way? Have you even looked at the file? There's absolutely nothing in there that anyone fooling around with their own init.d file couldn't have done. There is no custom code written in there by faux that someone else couldn't independently have written. Should he be credited for it? Absolutely. Is he owed any compensation for this? I really don't think so. Those who want to contribute (and make no mistake, his kernel is pretty great) can do so by purchasing his app or donating to him.

Excuse me? In what way? Have you even looked at the file? There's absolutely nothing in there that anyone fooling around with their own init.d file couldn't have done. There is no custom code written in there by faux that someone else couldn't independently have written. Should he be credited for it? Absolutely. Is he owed any compensation for this? I really don't think so. Those who want to contribute (and make no mistake, his kernel is pretty great) can do so by purchasing his app or donating to him.

Friends these tweaks are all over the XDA forums including the Faux's kernel threads. I have only consolidated them. Btw I myself own Faux applications and they are great, of course.
This is not a place to fight rather it's a place to share knowledge. So calm down.

come on dude !!! he has just gathered his settings into a zip file and just made it easier for users to simply flash it n apply the settings he is using...there is no harm to the dev's hard work behind his kernel n app !!!

i just thought it might be better if he post the setting as a reply in faux's kernel thread instead of making a new one. Well, just my opinion

Well friend, you are right I thought of posting my init.d to that thread but I am not sure why I posted a new thread (there was a some reason, I forgot). Anyways I will post a link referring to this thread.

[SCRIPT][UPDATED 03.26.14] Fix Lag, Defrag/Free Memory with |=>TrimDropOff<=|

Updated 03.26.14 - Released v2.1 - bug fixes and code cleaned
Introduction:
I am by no means a developer. I am just an android enthusiast who has learned a bit of bash. The reason I made this script was that settings>>wifi>>advanced was not promptly turning wifi off when my device would sleep; sometimes it would not turn off at all. So I figured since I am making a script to resolve this issue I might as well add a couple of other functions as well. To this end I noticed some people saying THIS APP was helpful and I missed the Flush-O-Matic script from V6 SuperCharger so I added fstrim and drop_caches=3 to the script.
Click to expand...
Click to collapse
What will this do?
The script will allow you to sync wifi, fstrim, and/or drop_caches=3 with sleep and/or it will allow you to schedule fstrim and/or drop_caches=3 using crond. The scheduling option can work on either a hourly (you can choose to run desired programs every hour on the hour, every two hours on the hour, every 3 hours on the hour, etc) or daily basis (you can choose to run desired programs at a given time on the hour).
Both the sync and schedule options will load themselves in to memory each boot and each time your device goes to sleep and/or when scheduled the scripts will depending on your options: (1) sync your data so as to ensure no data is lost; (2) TRIM your /system, /data, and /cache partitions; (3) DROP CACHES = 3; and (4) turn off wifi.
In addition, there is also an on-the-fly script to manually trim partitions and drop caches when desired.
Click to expand...
Click to collapse
Benefits:
Reduce lag/improve i/o efficiency (see THIS and THIS).
Although android automatically invokes fstrim when certain conditions are met, these criteria could seldom if ever be met depending upon your usage style. The init.d script should ensure fstrim is invoked more frequently for most users.
Should use less ram than apps that perform similar functions (I say should because I have never used such apps, but I imagine they consume more that .2-.5 mb of ram).

Requirements:
root
init.d
busybox
fstrim (should be in all nexus 4.3+ roms)

Warning/Disclaimer:
Although these scripts function as intended on my device – Nexus 7 (2013), SlimKat (weekly), ElementalX...Use at your own risk. Neither I nor XDA are responsible for any possible deleterious effects.

Click to collapse
Known Issues/Bugs:
If you use the sync option, scripts with a lower priority than Z99 will not execute.
The log files don't always display as intended...dunno why...any help/suggestions would be appreciated.
Let me know if you find any others .

Install, Usage/Verification, & Uninstall:
Install -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
make a nandroid backup
download the zip (<<NOT flashable) attached to this post
extract the zip’s contents
if you were/are using the first version of this script manually delete: /etc/init.d/07TrimDropOff, /data/TrimDropOff_Awake.log, and /data/TrimDropOff_Sleep.log
run TrimDropOffInstaller with superuser permission via terminal or script manager.
follow the scripts prompts
reboot
enjoy
Usage/Verification -
Assuming you have followed the install procedure, next, put your device to sleep and then wake it if you are using the sync option.
Now check the various logs in /data/TrimDropOff. The logs will show the time, the script’s PIDs, the path of the PIDs (just to double-check the PIDs are correct), the ram used by the PIDs, action(s) preformed (amount trimmed from each partition and/or if drop_cahes was run), or errors.
If you want verify manually via terminal do [pgrep -f TrimDrop] for the sync option or [pgrep crond] for the scheduling option to get the PIDs, do [cat /proc/PID/cmdline] for each PID to verify it truly belongs to Z99TrimDropOff or crond, and do [dumpsys meminfo | grep PID] for each PID to verify ram usage (this command will yield duplicates, which can be disregarded and may output undesired additional results, which can be filtered by looking through the results for the relevant PID).
To use the on-the-fly script to trim and/or drop as desired, in terminal do [su -c trimdrop].
Should you want to reconfigure your setup, uninstall before reinstalling to avoid potential issues.
Uninstall -
Note: If you use crond for other tasks, both the install and uninstall routine account for this potential contigency and should leave your other crond tasks uneffects.
Rerun TrimDropOffInstaller with superuser permission and use uninstall option at the beginning of the script.
Reboot and all will be back to as it was before.

Changelog:
v2.0
made in to installer script
added cron options
added bootloop precautions to the init.d scripts (should make it compatible with all devices that meet the requirments)
the on-the-fly script, trimdrop, now allows user to choose fstrim and/or drop_caches=3
added more syncs to further ensure no data is lost
a bunch of other stuff I probably forget
v2.1
bug fixes - fixed issue if using only sync option (missing directory); fixed display of irrelevant errors in uninstall routine
cleaned code a bit (reduced redundancy)

Don't forget to click THANKS and RATE 5 STARS if you found this useful :highfive:.
peep my other script SwapItOn
Update to v2.1 if you were only using the sync option.
If you were using both the sync and schedule options or only the schedule option there is no need to update; the bug I found would not effect you.​

reserved...on the off chance it will be needed

Thanks, sounds interesting. I'm assuming the zip can be flashed right after flashing a new rom?

Oh, thanks

Is compatible with custom kernel? Franco in my case

Will performing trimming operations too frequently cause additional flash memory degradation?

As you were informed the zip is NOT flashable. If there is sufficient interest (say a 100 downloads) I'll make it flashable/aroma.

Yes, it should be compatible...the fstrim utility is part of the rom (it should be in all nexus 4.3+ roms).

No, to my limited knowledge it should not be harmful (in fact it should increase lifespan - google "fstrim lifespan"). Did a quick google search but could not find anything definitive/reliable regarding frequency...what I did see seemed to suggest 'no' though.
If you are concerned about the frequency, you could not install the init.d script and just use the on-the-fly script, trimdrop, to trim on-demand. Should there be interest and if I have the motivation and time, I have been thinking about making this in to an installer script and/or aroma zip with cron-based options so it could be scheduled hourly, daily, or weekly.

Scheduling options would be awesome!

Seems there is a decent amount of interest (almost 100 downloads already ...thanks peeps), as such I'll add options and make things more configurable.
Regarding scheduling, I was thinking of doing hourly, daily (with ability to choose time), and weekly (with ability to choose day and time) options. Would every other hour or some other setting be desirable?
Regarding installation, what would be the preferred method, an installer script (e.g. V6 SuperCharger) or AROMA? Flashable zips would be another option, but would have less options/be less configurable.
Gimme some feedback and I'll put something together in the next week or two depending on work and my motivation .

wasn't this a nexus 7 2012 issue and fixed in the new version 2013?

My 2 cents:
I would choose a daily option for my device.
I prefer Aroma over a script, but if you cannot get the customization you want with Aroma, then by all means go with a script.
Thanks again for the script and willingness to make it even better!

Thanks for the scripts, I time my startup, and this improved startup time by about 3-4secs, among other noticible improvements, apparently the stock OS does not run fstrim enough, initial operations freed several gigs on the data partition, and hundreds of megs on the others...

Im going to turn this into a cron job, that will take care of scheduling, unless anyone else gets there first ( please lol )
Will give it a go in its present form, whats its resource footprint just sitting there waiting for screen off ?
Can we trigger the action from the screen off event ? or some other interupt type way ?
Great script by the way, your bash is damn site better than mine, jealous lol

Yes, I think this is true to a degree...it was more of a problem on the 2012 and other nexus devices. See the links in the OP for the conditions that need to be met for fstrim to autorun...for some users (myself included) the conditions will seldom if ever be met. Also see @mdamaged post; I get similar results the first time fstrim is initiated by my script after each boot...subsequent runs normally only frees up memory on /data.

See the first post on this page and my response to @creeve4 and @imfun in this post. I will make an AROMA package with cron options for fstrim and drop_caches=3.
However, should you feel ambitious and beat me to it, props to you...I will give you full credit in the OP and link your post as the d/l source so you should get the 'thanks' too.
Regarding triggering with screen on/off or some other event: It can probably be done, but I it's beyond my knowledge (screen on/off was actually the first trigger event I looked in to using, but despite fairly extensive searching I could not find how to detect it).
Regarding resource footprint: Read the OP (usage section) it explains where to find the log which contains this info and how to do it via terminal (should you not trust me )...also see OP (benefits section): in all my testing I have never seen it use more that .8 mb, but most of the time it is less than .2 mb.

Okay will get to making an AROMA package...it will be my first, but it looks easy enough :fingers-crossed:...gimme a week or two to put it together and fully test.

Can't wait already, because after whole day or two, hard usage of my nexus 7 tablet, the tablet starts to get laggy. I can see this on web browsing, touch press delay time, and onyl rebooting seems to help... Hope after istaling this will solve the problems

For an aroma script you will prob have to stick the file in /system/etc/cron/cron.hourly, daily, weekly and just give peeps that choice, will be most simple way. Ps not a fan of aroma lol

Ok, I should have spotted this issue right away, but did not, so here goes. It seems the use of while loop in the script in the OP causes any scripts with a lower priority in init.d to never get ran, if the script in the OP is the only one in your init.d this does not matter, nor should it matter if you have at boot script with a higher priority (they get ran before the OPs script).
I run the ElementalX kernel which depends on a init.d to initialize some parameters for the kernel, with this script in init.d they never get initialized, in my case this resulted in some things not 'taking' such as the battery life extender, which on my device, is set to stop charging at 4100mv, however, since the while loop kept the ElementalX init.d from running, it kept charging to ~4300mv, this is how I noticed (actually none of my settings wrt ElementalX were being initialized, but this symptom was most pronounced).
A simple fix would be to move up the priority of the ElementalX init.d script, but this would have to be done after each flash, and frankly since I run Tasker anyway, I saw no need for this, what I did was remove the OPs script from init.d and simply made a very simple task in Tasker to run /system/xbin/trimdrop when display goes off, it could just as easily be a time event.
Anyways, hope that helps someone who may come across this with other kernels, or other at-boot scripts which depend on being ran before the OPs script.
Again, thanks to the OP for his work. Also, I added another sync just before the drop caches, since the state of dirtyness could change after the fstrims.
