[BASH SCRIPT][UPDATED] Governor Switch Scripts from the Command Line

UPDATE: Govswitch.sh has received an upgrade and it can now automagically generate an init.local.rc.new which can be used to set a governor on start up. It will also generate the chosen governor specific script and place it in the /system/bin folder. Thank you Duffkitty for the idea!
Original Post:
In the spirit of Open Source, I've written a couple of scripts that I wanted to share with the community. These are meant for advanced users familiar with the *nix command line. I didn't want to buy SetCPU (yes, I'm cheap ) so I decided to automate the process through the Bash shell language. For those interested, I've written a couple of Bash scripts that allow you to switch CPU governors via the command line. One script generates single instance scripts (one per governor) that can be used in conjunction with GScript for single click governor shortcuts. These single instance scripts are also ideal for changing the governor at boot. The other is command line only and prompts the user to choose from the available governors on the system.
I got tired of having to type it all out so I scripted the process. I just wanted to share with everyone else. I'm also planning to write a watch script that changes to the powersave governor automagically if the battery gets low.
I hope someone finds these scripts useful. Please let me know if anyone finds any errors in the scripts.

Despite my harsh warning above, I've designed these scripts to be as failsafe as possible so that nothing is written if the user does not want changes or the governor being selected is already in use. I use these scripts all the time and I have tried to make them as user friendly as command line scripts can be.

govscriptgen.sh
Description: This script generates a set of scripts, one per governor to '/sdcard/governors/'. If a governor is not available in the kernel, no script is generated for it. IE: You can't have ondemand on a kernel that only has interactive built in as the only governor. If you do happen to run a governor script for a governor that is not available, it will simply exit with an error message and no changes made.
Example:
Run:
Code:
bash /sdcard/govscriptgen.sh
Then:
Code:
bash /sdcard/governors/ondemand.sh

Please let me know if you have any questions.

At first I got a yesno error but ran it with sh and not bash.
Working but I can't figure out gscript it sends out stderr's. I have the lite so dunno.
I'm guessing to start at boot I would need to edit a bit =P

I found this for running scripts at boot. It's a good place to start.
http://forum.xda-developers.com/showthread.php?t=690564&page=2
govscriptgen.sh
This script generates a set of scripts, one per governor. It's those scripts you would want to use at boot or in gscript. If you didn't change the location, and assuming that you could write to your SD Card, they should be located in '/sdcard/governors'. There will be one per available governor (this is dictated by the kernel configuration).
In GScript do the following:
1. Open GScript Lite.
2. Menu > Add Script
3. Name the script. Let's say Ondemand.
4. Check 'Needs SU?'
5. In the text box type (without quotes), 'bash /sdcard/governors/ondemand.sh'
6. Create a shortcut to that script and it will set the governor it is named for.
govswitch.sh
This one is for use in a terminal and prompts the user for the desired governor.

I think I figured out and was gonna post it but you already did thanks. I appreciate it.

I'm glad it worked. Yeah, Android's command line fought me most of the way until I learned to just call bash before running any scripts. I suspect it's probably because the command line on Android initializes in a relatively 'bare' state as compared to all of Linux's bells and whistles that I'm used to.
Let me know if you have any more questions.

I started on Slackware and a '/etc/rc.d/rc.local' file would be really awesome. Slackware being one of the oldest distros (if not the oldest) is very similar to BSD. I've had to configure Slack many times, but once you did it was rock-solid.
Android feels more like Ubuntu in some ways and Red Hat in others, but a very slim version of either. I can't really explain it.
Anywho. Glad I could help.

How did you write this script one month in the future?
Seriously....would this script be able to change kernel voltage from command line? Say changing from undervolted to regular voltage for certain tasks (like GPS nav for example), then switch back to undervolt for other usage? Is something like that even possible? I've seen a few others ask about something like that in other threads.

If there is a command line associated with it, I can write a script that can easily handle it. I haven't looked into the specifics on changing voltages...
TBH: That thought scares the bejeezuz out of me.

These are kernel level calls that have to be compiled into the kernel. Unless they make this available as a system variable, like the governors are, I don't think changing the voltage from the command line is possible... or even safe. The governors are routines written to control different CPU modes of operation and are designed to be fairly safe to use in instances of power management. Adjusting the voltages from the command line would prove to be too close to suicidal because Bash can't operate at the speeds necessary to monitor voltage fluctations.
Example: We hit a voltage spike, which needs to be corrected in nanoseconds (billionth of a second), Bash would brick the phone by not responding until at least 50 milliseconds (thousandth of a second) later, if ever.
Now if they had modules written that the kernel had different voltage 'modes' and built-in safeties, then I wouldn't have a problem manipulating them from the command line. As it stands, I'll leave it to people who think in ARM Assembler, C, and C++. lol

However, I am taking script ideas, so feel free to suggest anything else you might think is useful.

Govswitch.sh has received an upgrade and it can now automagically generate an init.local.rc.new which can be used to set a governor on start up. It will also generate the chosen governor specific script and place it in the /system/bin folder. Thank you Duffkitty for the idea!

do u mean this one ?

Code:
Code:
# sync
# echo 3 > /proc/sys/vm/drop_caches
That's it. Not much to see here. The first command writes any cache data that hasn't been written to the disk out to the disk. The second command tells the kernel to drop what's cached. Not much to it. This invalidates the write cache as well as the read cache, which is why we have the sync command first.

and from my opinion , it's better to echo 1 back to drop_caches, cause the caches which are still in use may be cleaned whenever u go task manager and clear ram
correct me if i'm wrong

Try this one

echo ""
busybox sync; echo 3 > /proc/sys/vm/drop_caches
sleep 3
echo 1 > /proc/sys/vm/drop_caches
ramused=$((`free | awk '{ print $3 }' | sed -n 2p`/1024))
ramkbytesfree=`free | awk '{ print $4 }' | sed -n 2p`
ramkbytescached=`cat /proc/meminfo | grep Cached | awk '{print $2}' | sed -n 1p`
ramfree=$(($ramkbytesfree/1024));ramcached=$(($ramkbytescached/1024));ramreportedfree=$(($ramfree + $ramcached))
echo $line
echo " ...RAM Stats AFTER Engine Flush"
Plus you ain't sleeping between the echo 3 and echo 1 - so sometimes that won't work.

[GUIDE] Add init.d scripts support for padfone/padfone 2

First of all, if you don't know what does init.d means then you probably won't need this and I'm not responsible if your padfone explodes when running this . Seriously this is almost completely sure but your device, your responsibility.
Credits:
I gathered information from this thread from DooMLoRD http://forum.xda-developers.com/showthread.php?t=1236446 as well as from others in this forum, but i believe he was the first.
Pre-requisites:
A rooted padfone, busybox and a command-line (adb, terminal, ...)
Explanation:
We are going to use the install-recovery.sh script that recreates the recovery partition (if it has been modified) while the device boots.
The way it works is simple:
- the boot process calls install-recovery.sh while executing init.rc
- the install-recovery.sh calls sysinit script
- the sysinit script runs /system/etc/init.d/* in order
Issues:
I found that the script is called in an early state where the date is still not set (is said Jan 28 1970!!!) and only a few fs are mounted:
/system, /data, /persist, /cache
so no sdcard, no Removable ...
Howto:
you can either copy the following text to a file in your device or download the attached file and in a terminal run:
$su
#cd to the directory where the script was stored
#sh ./enable_initd.sh
Code:
#!/system/bin/sh
echo ''
echo 'This script will enable init.d'
echo ''
echo 'You will need to reboot to check if it worked'
echo ''
echo 'If the script successfully enabled init.d you will'
echo 'have a file in /data/log called init.d-log.txt'
echo 'after the device is done rebooting.'
echo 'Once checked that it is working, you can delete'
echo '/system/etc/init.d/99test and /data/log/init.d-log.txt'
echo 'Remember to always set the proper permissions in your'
echo 'scripts or they will not work.'
echo ''
if [ ! -f /system/xbin/busybox -a ! -f /system/bin/busybox ]
then
echo 'no busybox found! please re-install/update your busybox'
else
# Mount system as rw in order to prepare the paths and scripts
mount -o remount,rw /system
# Create init.d dir
if [ -d '/system/etc/init.d' ]
then
chmod 755 /system/etc/init.d
else
mkdir /system/etc/init.d
chmod 755 /system/etc/init.d
fi
# Create sysinit script if needed
if [ -f /system/bin/sysinit ]
then
echo 'sysinit exists, init.d should be enabled'
chmod 755 /system/bin/sysinit
else
touch /system/bin/sysinit
echo '#!/system/bin/sh' >> /system/bin/sysinit
echo 'export PATH=/sbin:/system/sbin:/system/bin:/system/xbin' >> /system/bin/sysinit
echo '/system/bin/logwrapper busybox run-parts /system/etc/init.d' >> /system/bin/sysinit
chmod 755 /system/bin/sysinit
fi
# Create / modify install-recovery.sh
if [ -f /system/etc/install-recovery.sh ]
then
if cat /system/etc/install-recovery.sh | egrep -i "sysinit"
then
echo 'sysinit already present in install-recovery.sh, skipping this step.'
else
cp /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
echo '' >> /system/etc/install-recovery.sh
echo '#init.d scripts integration' >> /system/etc/install-recovery.sh
echo '/system/bin/sysinit' >> /system/etc/install-recovery.sh
fi
else
touch /system/etc/install-recovery.sh
echo '#!/system/bin/sh' > /system/etc/install-recovery.sh
echo '' >> /system/etc/install-recovery.sh
echo '/system/bin/sysinit' >> /system/etc/install-recovery.sh
chmod 755 /system/etc/install-recovery.sh
fi
# Create 99test script to check if init.d works
echo '#!/system/bin/sh' > /system/etc/init.d/99test
echo '' >> /system/etc/init.d/99test
echo 'date >> /data/log/init.d-log.txt' >> /system/etc/init.d/99test
echo 'echo init.d works >> /data/log/init.d-log.txt' >> /system/etc/init.d/99test
chmod 755 /system/etc/init.d/99test
# Sync and remount system
sync
mount -o remount,ro /system
#done!
echo 'job done :)'
echo 'reboot your phone and check on'
echo '/data/log/init.d-log.txt to see if it worked'
fi

[SCRIPT][v1.4]Bug Reporter (ultimate debugging) -- The MUST debugging AIO tool!

Greetings
Hello everyone, I made a script to help developers solve problems and you become a more helpful user.
What does it do?
It exports to sdcard :
dmesg
last_kmsg
wakelocks
kernel version
logcat (normal and long)
radio (aka modem log)
getprop (aka build.prop)
running processes
partition info
mount info
RAM info
interrupts
boot logs from kernels like : nAa, lupus
Total maximum possible logs are 14 files.
What should I do? :cyclops:
Send files from the folder with the time-stamp you have just created or send the tar.gz'ed file to the corresponding developer to help him. Each time you run the script it creates a different folder with a unique time-stamp of the time and date you dumped the logs.
Send whatever is needed, everything is in bug_reporter folder.
Ok, how do we install this thing?
Make sure you download the latest version [ v1.4 is the latest ] which is attached below and put it in your sdcard...and that your device is rooted.
Go to CWM recovery and flash it! It does no harm, it just copies a small 6kb file in your /system/xbin. So there is no need to uninstall it later. It will accompany you until you flash a new ROM.
If you are coming from another version, just flash it over.
If you are having any problems, first attach the debug.txt from bug_reporter folder and tell me your device, kernel and ROM. The problem might be your busybox installation though.
Ok, how do we use this thing?
Make sure you have a terminal app, I use this : https://play.google.com/store/apps/details?id=jackpal.androidterm
Open a terminal app and just type :
Code:
su
bug
IT WON'T WORK PROPERLY IF NOT EXECUTED FROM /system/xbin/, SO IT MAY FAIL WITH SCRIPT MANAGER. TRY AND REPORT BACK TO ME.
That's it?
Yes. :good:
If you have any questions, feel free to ask anything. :highfive:
Any screenshots? :angel:
Yep.

CHANGELOG
Code:
[B]v1.4[/B] [B][COLOR="Red"]MORE FEATURES[/COLOR][/B]-[COLOR="SeaGreen"]WORKS ON ALL SUPERUSER APPS[/COLOR]
- alternative root check
- now it's [B]not[/B] necessary to have SuperSU, you can use whatever you want, but you have to type [B]su[/B] first
- added additional logging of : [B]running processes[/B], [B]partition info[/B], [B]mount info[/B], [B]RAM info[/B], [B]interrupts[/B], [B]boot logs[/B] from [B]lupus[/B] kernel
- avoided potential bug with radio logging
- added some more info about kernel version logging (with [B]uname -a[/B] command)
- code clean up and more easier to follow
- faster? (it takes 1 second for me)
[B]v1.3[/B] [B][COLOR="Red"]ROCK STABLE[/COLOR][/B]-[COLOR="SeaGreen"]THE BEST[/COLOR]

- added build.prop backup with getprop command, it will help devs understand more info about your situation
- added some sort of advertisement of the script, so that it'll become popular
- added compression of the last logging folder, so that you can easily send it to dev(s)
- added more info on the script, made more presentable and explanatory for those who are willing to modify it
[B]v1.2[/B] [B][COLOR="Red"]STABLE[/COLOR][/B]-[COLOR="SeaGreen"]FULLY TESTED[/COLOR]
- finally fixed logcat exporting, now it will work for sure, fully tested
- cleaned up the script a lot and made it simplier for reading
- added radio (aka modem log), wakelocks and kernel version logging
- fixed terminal output logging for debugging better
[B]v1.1[/B] [I][COLOR="Gray"]it won't logcat, but everything else works[/COLOR][/I]
- fixed wrong logcat exporting, now when it's disabled, you'll know it
- added an auto-check for vaccuming logs after reaching above the MB size you set (logs can easily reach 10 MB)
- small bugfixes
- root check, in order to be sure we collect logs as root
- terminal output logging for debugging reasons
[B]v1.0 beta[/B] [I][COLOR="Gray"]works, but has many errors, it may even fail to flash.[/COLOR][/I]
- initial release

Thank you very much, this script will help a lot of people, including me

Is it possible to move this bug file to system/xbin instead of flashing it (gives error). And if yes, what should be the permissions?

It's fixed. Just flash bug_reporter[v1.0]-nAa.zip, the permissions are 755. If you are unsure about permissions, see this : http://www.draac.com/chmodchart.html
But I am telling you to flash the fixed zip, it'll work.

nice concept ,,but there are some problems
after taking log
both lastkmsg and logcat file show nothing(empty files)
long logcat shows this: 9 com.android.settings
only dmesg is correctly extracted

UPDATE!
Code:
[B]v1.1[/B]
- fixed wrong logcat exporting, now when it's disabled, you'll know it
- added an auto-check for vaccuming logs after reaching above the MB size you set (logs can easily reach 10 MB)
- small bugfixes
- root check, in order to be sure we collect logs as root
- terminal output logging for debugging reasons

Thanks man, I was going to write something similar until I found this.
I cannot attest to the zip's functionality as I use it with script manager, but I can say version 1.0 worked perfectly (producing the three possible proper log files) for me. Version 1.1 not so much it tells me 'I can't logcat' when I clearly can; gl with your 'main not found' problem.
Also a suggestion maybe include in your zip a copy of the script that goes to /sdcard/ so the user can easily access it in order to facilitate using it as a widget.

Indeed, logcating won't work no matter what. It's a bug. I am aware of it. I'll fix it today I guess along with some code cleanup and considering your suggestion.

Might convert this to external scripts for windows and unix as well. Btw, why the root checker? If it needs to be in system/xbin then you already have root

:victory: Yeah, do whatever you want with it!
About the root check... Have you ever thought of "just in case" case? Well sometimes sh!t happens... Like the 7+7=16 embarrassing situation on final exams for example.
Anyway, probably won't need this check on other unix systems... You'll need to start the script with
Code:
sudo -i
and remove any
Code:
su -c
in the script. Also some logging files are available only for android, like logcat and logcat radio. If you need any help with converting I can help you both for windows and unix, just PM me.
EDIT : Opss, root check is buggy, I've discovered it thanks to you! I'll upload a fixed minor revision later.

About the root check... Have you ever thought of "just in case" case? Well sometimes sh!t happens... Like the 7+7=16 embarrassing situation on final exams for example.
Anyway, probably won't need this check on other unix systems... You'll need to start the script with
Code:
sudo -i
and remove any

su -c

I mean set up a script to run from a pc to debug android. Let's you run it on non rooted devices (parts of it anyway)
It's quicker than getting a user to push and run via the android terminal (which not everyone has)
Easier to run via an adb interface which can be supplied, and implement an update script everyone is running the same version
Btw won't need help check my signature for the root scripts

UPDATE! The tool is now in a super stable state of development.
Code:
[B]v1.3[/B] [B][COLOR="Red"]ROCK STABLE[/COLOR][/B]-[COLOR="SeaGreen"]THE BEST[/COLOR]
- corrected root check
- added compatibility with CM10.1, it uses an older version of su and the script will ask you to install SuperSU to update it
- corrected and re-ordered some text
- optimized script speed by removing unnecessary su requests (it just takes 3 secs to finish)
- added build.prop backup with getprop command, it will help devs understand more info about your situation
- added some sort of advertisement of the script, so that it'll become popular
- added compression of the last logging folder, so that you can easily send it to dev(s)
- added more info on the script, made more presentable and explanatory for those who are willing to modify it

can i get permission for adding your script in my cm-10.1 for LG-P350 ?

Just sharing. I use this:
bugreport > /sdcard/bug_report_`date +"%Y%m%d-%H%M"`
You may want to incorporate it in some way.

Thanks, I'll have it in mind, the reason why I didn't do this before is that I wanted it to be simple and not so informative.
In next update I might add some colors too!
Anyway here is an update... :fingers-crossed:
Code:
[B]v1.4[/B] [B][COLOR="Red"]MORE FEATURES[/COLOR][/B]-[COLOR="SeaGreen"]WORKS ON ALL SUPERUSER APPS[/COLOR]
- alternative root check
- now it's [B]not[/B] necessary to have SuperSU, you can use whatever you want, but you have to type [B]su[/B] first
- added additional logging of : [B]running processes[/B], [B]partition info[/B], [B]mount info[/B], [B]RAM info[/B], [B]interrupts[/B], [B]boot logs[/B] from [B]lupus[/B] kernel
- avoided potential bug with radio logging
- added some more info about kernel version logging (with [B]uname -a[/B] command)
- code clean up and more easier to follow
- faster? (it takes 1 second for me)

[Tweak][Guide] Init.d Tweaks

Init.d Tweaks
(Needs ROM (Kernel) With init.d Access And Busybox, Open Empty File In Text Editor (Notepad ++ Or Similar), Insert Tweak You Want In Header,Save in /system/etc/init.d and name it Lomething Like 73tweaks)
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;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. Vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. Misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
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
Code:
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 $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
Code:
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(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
13. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
14. GPS.conf
(create or edit your /system/etc/gps.conf with a text editor)
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
Warning: Using these tweaks may brick your device. Use it with caution.

Install Universal Init.d from Play Store and follow in-app instructions. Init.d support will be enabled on your device. Your device must be rooted first.

I make and init.d script and i copy your custom values to my init.d script. However, on net speed tweaks, the tcp_rmem and tcp_wmem didn't change the value at all even i edited it. Any help?

Should it be in text file or script file?

So we create a different text document containing each code for each tweak?? Not all In one document in the init.d folder??

Nice write up, bro. Thanks. Will have to try.

Guys so why aren't these enhancing tweaks and buildprop tweaks already available in our phones? Why aren't our phones optimized?

Tweaks good for one person or situation are not necessarily optimal for every case in general .

Can you help please?
Hello, I'm a newbie here. I wish to overclock my stock kernal, So it can be done through tweak? or I have to compile new overclock kernal from stock kernal source? Their's already a overclocked kernal for my device but its for cm11 and i want to use it on 4.1.2 JB stock ROM. Is their any simple way out?
Your help will be appreciated. Thanks .

use cm11 for s7392 or try
cm12 new developed
or stock i did give it to you before
choice is yours.......
i no longer have this device

Thanks for suggesting new Cm12 kernal.
As of cm11, X264 encoding is important for me, plus their were some other minor bugs in that build. Though i agree its the best build compiled rom for Trend.
I will myself start some project after June~July.
What happened to your device though? You are among the few members who are guiding peoples on threads related to this device and i really appreciate it.
