[SCRIPTS] & [TWEAKS] - Updated 2.22.13

*****************************************************************************************************************
OK! Listen up! A little disclaimer before we begin...

Now that, that is done and over with let's begin, shall we?
I have scoured the vast online community, that is the great XDA and have researched and tested various scripts(init.d) and tweaks(build.prop and gps.conf) to help our greatly handicapped Droid Charge somewhat "compete" with the big boys.
Dwitherell has kindly uploaded them to Tweaktools.
You may ask init.d? But we have a stock kernel that doesn't support init.d... Thanks to this post and Dwitherell's genius we have working init.d baked right into our ROM, yes that's right baked in!
P.S. - We now have a custom kernel that is able to use init.d tweaks without any hacks... Lazarus Recharged Kernel
RENICE Tutorial
Renice operates on the principal that the lower the value of the process (the scale is from -20 to +19), the higher the priority the process has on CPU time. In other words, a process that is nice to others, is +19. One that isn’t so nice is at -20. In function then, a process that requires lots of immediate CPU time such as a launcher, benefits from running at a higher priority (thus as a negative on the niceness scale) than, say, Google Maps.
***MAKE SURE TO CHANGE THE FIRST TWO ENTRYS TO YOUR CORRESPONDING PROGRAMS!***
***To add/remove other program names, change the PNAME value.***
Simply open your favorite file explorer(I recomend Script Manager, it is an all around good program), navigate to /data/data and in there are your programs. What I do is long press(in Script Manager) on the program select rename and copy the name, then paste it into the renice script. Simple as that.
Another way is to go to the Play Store find the app that you're trying to re-nice and click the share icon select Gmail or Messaging and you'll get a link. At the end of the link you'll see id=xxx.xxxxxxx.xxxxxxx copy what's after the equals sign and simply paste that into the script.
Feel free to add/delete programs from the list to suit your needs, as well as change the priority values.

Have you seen the AGPS patch here? http://forum.xda-developers.com/showthread.php?t=1250226
Grab the Google specific No-SSL version. It's the one I bundle with my Rezound rom, and it's fantastic. He runs his own XTRA servers, updated with fresh data every 30 minutes, and runs his own stratum 2 NTP server just for AGPS. The patch also contains a lot more config tweaks related to AGPS timouts and accuracy requirements. The Rezound GPS isn't bad on it's own, but that gives it into the best GPS performance I've ever seen, including my $350 handheld. It locks in 2 seconds, locks to multiple satellites indoors, gives sub-10ft accuracy, etc. I don't know how well it will do on the Charge, but seeing as how both phones use Qualcomm chipsets, I can't imagine that it wouldn't work for the Charge.

Also... init.d stuff is not officially implemented... yet

Just installed with no issues and performed the required 2 reboots. The second reboot was three times faster than any other time I've rebooted. Is this a benefit of the tweaks?

Glad to hear it works well here. I remember GPS being awful and inconsistent on this phone.

Holy crap shrike. On my first go it locked onto 12 sats in 15 seconds on a cloudy day. The thread says the first time takes usually 20 seconds so I'm looking forward to using this over time.

I did something wrong. I installed init.d then copied 77tweaks and renice into the init.d file. I rebooted it once and it went fine. Then after i replaced the build.prop file with the down loaded one I restarted it and it went into boot loop. At least I guess that's what it is when it turns the Samsung screen off and on and won't go past it. I re-odin'd Tweaked plus cwm and fixed it.

Hum. Did you mount the system as R/W? Also maybe try using Script Manager and see if that does anything.

[SCRIPT] Run init.d scripts once every N days [ZipAlign/SQLite3/others]

There are many ROMs that include the ZipAlign or SQLite3 vacuum on boot, but these command are not really needed to run on EVERY boot, once every few days can be enough, so I came out with this script.
To run it, you need to have busybox with the stat applet (should be there always), which gives information about a file, including last modification date.
This is done is by checking the last modification date on a file, which is touched or changed only when the main script is executed.
Currently I modified the ZipAlign and SQLite vacuum in my own rom to use this technique, and they seem to work fine. The monitored file is the log of the operation done, which is stored in the /data/ directory

This looks like a great idea :good: is it possible to easily change the intended interval at which yo want the scripts to run though?

Sure, check the examples I posted, they are well commented. Just change the value of the "RUN_EVERY".

There is no much sense of zipaligning system apps every x days, once they are zipaligned (when making the ROM zip), they remain zipaligned. some apks might need zip aligning if they get moved/installed as system apps after rom install.
Not to mention the stability, I don't know the exact boot mechanism of android, if you start zip aligning system apps during the init.d, it might cause instability to some system apps.
But if you mount the /system partition as read/write, do the zipaligning loop, then remount it as read-only, it should be possible.
still, I don't recommend doing so....

i pushed many apps from /data/app to /system/app.
I deleted the libs from the apks and copied them to /system/libs to saved space. however I forgot to zipalign the apks after removing the libs. I used the zipalign script from the rom toolbox app unfortunately it didn't work as expected. it just deleted the apps that should have been zipaligned.
I don't really want to zipalign /system at every boot. just once for the modified apks.

# SQLite database vaccum
# Frequent inserts, updates, and deletes can cause the database file to become fragmented - where data for a single table or index is scattered around the database file.
# Running VACUUM ensures that each table and index is largely stored contiguously within the database file.
# In some cases, VACUUM may also reduce the number of partially filled pages in the database, reducing the size of the database file further.
# sqlite3 binary in /system/xbin is required!

Hi guys! I recently installed lollipop touch wiz and installed the two scripts on the Op, managed to get the sql script to work fine but when the zip align tries to run it errors out in the log, any advice to what I've done wrong or if you guys know of a change in lollipop that doesn't play nice with zip aligning?
Starting Automatic ZipAlign 06-04-2014 15:23:01
ZipAligning *.apk
ZipAligning *.apk Failed

All I've done as far as modify the script is I got rid of the color tags.
Also the sql log shows the correct date as well, where this script does not.
Thank you in advance guys!

Any chance to make this flasheable thx!

how to make an specific init.d script runs every x minutes?
and when unlock the screen

[MOD][REF]Set governer on boot with init.d

Since everyones asking how to set a governor on boot, heres a sample of my init.d script that sets "on demand" with max frequency 1400000 (1.4GHZ) and min frequency 200000 (0.2GHZ) on boot, if you would like to use it or modify it let me know, i dont bite and im one to help! enjoy!!
here's the guidelines!
100000 = 1GHZ

This is my Script to set / tweak my Governor on my XZ.
It's easy to handle, i guess.

do i only have to change ondemand to hotplug to work on hotplug governor?

If your Kernel supports it, sure.
You can set any available Governor on your Phone.
Just edit
GOVERNOR="hotplug"
To tweak it, just search the Forum for available Values. My Phone doesn't support it, that's why it's not in the script.

How to set minimum gpu frequency? Will this work?:
# echo "325000000" > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/min_gpuclk

:good:

@Ricky Divjakovski
Sorry for disturbing
Please give the script in the post or give a mirror link sir..
All your threads are very helpful
Thanks

[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?

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

ohhh no dont want any credit lol lol, i have turned it into a cron job quite simply by adding it to the cron initilising script

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.

[SCRIPT] Helium server PC download - separation

This is simple linux script I've made to separate all apps from one big zip file made by Helium sever -> PC download. Helium wiki says to don't try to do anything with this file, but I didn't want to restore all that stuff that I've backuped before bootloader unlock on my nexus 4. I'm sure it can be writed better, but it's working
Just place script file and unziped backup folder (must be named "backup") in one directory. After execution of the script everything should be ready to copying to carbon folder on your sd card/internal memory and restoring like after normal backup.
Tested on Ubuntu 14.04.
I'm not responsible for data loss or any other problem. Use at your own risk.
Constructive criticism welcome.
