WARNING!
BEFORE you start modifying/
tweaking any system files, make
a BACKUP !
In that case you're save and you
have the option to restore the
system if you mess something up!
1. build.prop
For editing build.prop you'll need
a file explorer like Root
Explorer which is a paid app, or
you can use any root enabled file
explorer.
Solid Explorer is a really good
one!
build.prop is located in /system.
You can also use Android
Commander to pull the file to
your PC, edit it, then push it back
to the phone.
Here's a collection of build.prop
tweaks which should improve
performance:
NOTE: I've commented values (#)
which I'm not really sure about
what they do exactly. Or I find
they are optional.
Test them yourself if you want.
remove # in front of line, if you
want to enable it.

#If you don’t keep Wi-Fi active,

power if turning Wi-Fi off has
been forgotten when not in range
of a known network.

4. V6 Supercharging
][Script-U9RC8.2]Be A Super
User! Use The -=V6
SuperCharger=- Lag, Redraw &
RAM Fixer! - xda-developers

1.] Download V6 supercharger
and place it on your SDcard.
Optionally you can rename it to a
simple name like V6.
2.] Download&install script
manager from google play.
3.] open script manager and grant
it root privileges.
4.] Load downloaded script by
selecting it, tap superuser (SU)
icon (it will turn green)
5.] Tap 'run' in upper left corner
6.] touch the screen to open
keyboard.
7.] it will ask to set scrolling
speed, select 1 or 2 or 3 and then
enter. Or select 0 for instant
display.
8.] let it run until it stops
scrolling. It will then ask you
"Please Enter Option [1-30]:"
9.] Choose 10 for automatic
calculation of settings (V6 cust-
oomizer), or choose for yourself.
My personal choice is 5
[Multitask]
10.] let it do it's thing... after it's
finished it'll ask you if you want
to super clean&reboot, do it.
To verify if the script has been
installed, run it again after
reboot.
If all is gods, you should get
"Launcher is HARD TO KILL! ie.
SUPERCHARGED" and
"SuperCharger Level: 100%
SuperCharged!"

5. APK Optimisation
][DEVS] Optimize all APKs
automatically, Reduce memory
footprint! [Now with Zipalign] -
xda-developers
What it does: Makes APK's smaller
by compressing PNG files in it.
You gain a bit more space on
internal storage, and smaller
memory footprint!

and extract it
somewhere. Preferably to your
desktop. The folder is named
apkopt by default.
Open your ROM's zip. Open
system and extract app folder to
desktop.
Select all APK's inside app folder
and copy/move them to apkopt
folder.
Press win+r which opens run,
type cm which opens command
prompt.
now navigate to whereveryour
apkopt folder is and type
"apkopt_all".
The process will start, and it will
take some time to finish.
It will create two new folders,
"optimized" & "original".
Your optimized APK's are
obviously in the optimized folder.
You can compare how much in
size they've shrinked, for some
ROM's you can gain as much as
20Mb!
Create new folder called "app",
and place all optimized APK's in
it.
Open you ROM zip again, go to
system and replace the app folder
with the optimized one.
Now you can flash the ROM

6. ROM odexing
][ODEX] on Any ROM - xda-
developers
Odexing pros:
Faster boot, faster app loading,
gain more space in internal
storage.
deODEXED pros:
Modification of apk becomes
easier
ROM is open to theme
modifications
Further odex vs deodex info: xda-
developers - View Single Post -
[ODEX] on Any ROM
So, I think if you're not a ROM or
theme maker, you should be good
to go
Download this file:

odex-cwm.zip and put it on your
SDcard.
Reboot phone into recovery and
flash zip. It's as simple as
that
WARNING! Make sure you make a
nandroid backup before you flash
it!

7. Camera mod
[MOD][ICS&GB][4/26/12]Camera
HQ Mod: Extreme vs High (UPD:
MDPI GB version updated) - xda-
developers
ONLY for Sony stock camera app!

8. misc.
