I made a tutorial for other devices here http://forum.xda-developers.com/showthread.php?t=1500475
Why this tutorial?
I wanted a good odexed rom, but there isn't any here. So I tried to make my own odexed rom, but it wasn't so good. So I read something about re-odexing and tried it out. I modified it a little bit and I don't know all about re-odexing, so if someone know something better, pls post it here in the thread for everyone. Im working also on this thread, so I'll try to make few things like a flashable update.zip who executes the script. English is also not my mother language, but I hope you'll understand me
What is a odexed and a deodexed rom?
When you look at a stock rom in the folder /system/app, you will see files with the ending .odex and the apks doesn't contains classes.dex files. When you look at a deodexed rom, you'll see that there are no .odex files and the apks contains classes.dex files. Basically every apk contains a classes.dex files. Then the dalvik virtual machine generates a dalvik cache based of the classes.dex file. When you load a app, it will be loaded from the the dalvik cache, not from the apk. Samsung built the odexed rom using a tool called dexopt-wrapper. This tool generates .odex files based from the classes.dex, that means it does the same job like the dalvik vm. The .odex files were pushed in the /system. The files are the replacement for the dalvik cache. Like I wrote above, apps are loading from the dalvik cache, not from apk or classes.dex file, so classes.dex are not needed anymore, so they are deleted in odexed roms. Deodexing using xUltimate means regenerating a classes.dex based from the .odex file, merging it into the apk and deleting .odex.
What are the advantages and disadvantages from a deodexed rom?
Advantages:
-All needed things are in one apk, so modding/theming is (better) possible
-Needs less space on /system
Disavantages:
-Needs more space on /data, you have on some roms only 110/170 mb free(because a deodexed rom needs a dalvik cache for system apps and frameworks
-Is not so stable than a odexed rom(because some moves dalvik cache to a low end sdext)
-Slower on first boot(because a odexed rom has already execute ready .odex files, a deodexed rom needs to generate dalvik cache)
Why should I re-odex?
I wanted this, because I use ~100 apps and I have a slow sd card, so moving /data/app and /data/dalvik cache to sdext made my system unstables, which was needed to run ~100 apps on a deodexed rom. But when I tried it on a odexed rom, I had only to move /data/app to sdext. So I used long time Stock rooted JPU. But the system was not so fast than on any other custom rom and I hated the stock theme. So If you want more space on /data and you don't want to try out new themes, you should probably try re-odexing.
What do I need to re-odex?
-A full NANDroid Backup
-More than 30 mb free space on /system
-ADB drivers for Option 1
-Titanium Backup Pro for Option 2
How can I re-odex a Rom?
There are 2 Options to do it, but only the first does a full re-odex.
Before doing anything make sure that you have a full NANDroid Backup because you'll propably get into a bootloop.
Option 1 using dexopt-wrapper:
I used first the script from puppet13th, but I got into a bootloop. So I corrected the $BOOTCLASSPATH and corrected permissions, but I got also into a bootloop. I compared the re-odexed Kyrillos Rom v9.3 framework with the framework from JPU. The difference was that Kyrillos Rom v9.3 Framework files android.policy.jar and services.jar doesnt contained the Meta-Inf.
Step 1: Check jars
Pull all your framework .jars using this adb command to your computer
Code:
adb pull /system/framework
and open them in WinRar or sth and check that they contains the Meta-Inf folder. If some file doesnt contain a Meta-Inf folder, I attached all jars from Stock JPU, so you can add the Meta-Inf folder from them. When you are done with adding Meta-Inf Folder to one file, you can push it to the system using this adb command(services.jar is only for example, use your filename):
Code:
adb push services.jar /system/framework
Some users told me that you can re-odex the rom without being in CWM, so you can may skip Step 2, but you could get into a bootloop without Step 2, but you can try it out, there is no risk with a NANDroid backup
Step 2(optional): Reboot your phone into cwm recovery and get adb access there
I never got adb access in windows, but i got always access with linux. If you also don't get access on Linux, you should try to reboot your phone and to select then recovery in the extended power menu, this gaves me always adb access.
Step 3: run reodex script
I attached a script, which push a script and needed binaries over adb to the phone. Then it executes the pushed script, which creates odex files and removes classes.dex from apks or jars and rezipaligns apks and deletes the dalvik cache.
For windows users: double click on odex.cmd
For linux users: open a terminal and navigate to the folder which contains the unzipped attachment and run
Code:
chmod +x reodex.sh
./reodex.sh
After its finished, simply reboot and enjoy your fully re-odexed rom.
Step 4 (optional) convert /data:
I dont know if there is a better option, but after a re-odex with Option 1, my phone didnt showed the right free space on /data. So I converted /data to a other filesystem and back and then it showed the right free space.
Option 2 using Titanium Backup Pro:
You need to have Titanium Backup pro for re-odexing.
Step 1:
Select Menu -> More -> integrate sys dalvik into rom and wait until its finished. Then you should have more space on /data. I had when I tried it before 105 and after 135 mb free space on /data and 0kb free space after it on /system, so its not all.
You can also undo it. Its good when you want to try out a new theme, so you can undo and redo it using TB Pro.
Simply select Menu -> More -> Undo sys dalvik integration
and you're done.
Option 1 vs. Option 2
-Option 1 does a full re-odex, you have full free space on /data(Option 2 does only re-odex the apps, not the framework)
-Option 1 deletes classes.dex from apks and jars(against Option 2), so you have more space free on /system
-You can undo Option 2 fast, so theming/modding is also possible by undo, theme and redo it(against Option 1)
For other Phones:
If someone has a other phone, theres a chance for getting re-odex working, but I think that you should not hope that it works. You can try to put in the right $BOOTCLASSPATH. You can find the valid $BOOTCLASSPATH in /init.rc. Then replace the following characters with the $BOOTCLASSPATH in the script in the folder odex(beginning from Line 8):
Code:
BOOTCLASSPATH=replace_this_with_your_bootclasspath
cd /system/framework
for filename replace_this_with_your_bootclasspath
In the line
Code:
for filename replace_this_with_your_bootclasspath
you must replace the ":" character between framework files with a space.
For theme developers:
I dont know if it works that you use the re-odexed theme on a stock odexed theme. If it is so, you dont have to re-odex and deodex your phone, you can simply push the dexopt-wrapper binary to a folder, chmod 755 it and use it to make odex files from the needed apks and jars(all apks inside /system/framework has no odex files, so dont odex them) like this:
Code:
dexopt-wrapper /system/app/Phone.apk /mnt/sdcard/Phone.odex /system/framework/core.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar
You can change argument 1-2, but not argument 3(its the BOOTCLASSPATH)Then you could copy all needed main apks or jars to sdcard and remove classes.dex. Then only do Step 1 from Option 1 and you should have a theme for odexed rom.

Oh year I didnt see any tutorial before, but his is only for Froyo sense or Gingerbread aosp, so it wont work on galaxy 3 and I also wrote my tutorial so that noobs can understand it(I hope so).
I could also post a system.img of a re-odexed Kyrillos Rom v9.3 and other Roms, but I dont know if Im allowed to do that.

So the re-odexed kyrillos rom v9.3 is working faster than the original kyrillos rom v9.3??
Its not generally faster, but much faster for me because I have ~100 apps and when I run these apps on kyrillos v9.3 deodexed, i must move app and dalvik-cache to sdext which made my phone laggy. With a odexed kyrillos v9.3, i have much more space free on /data, so i only must move app to sdext which is much.
I wrote also the advantages and disadvantages from a deodexed and odexed rom in my tutorial.

So, in a re-odexed rom the HD2SD is not working ?
You use again froyo data2SD ?

As far as I understand, it works but only for data/app.
correct me if I'm wrong
Sorry, my english is not the yellow from the egg(you must not understand this).
Im using on my re-odexed rom also Hybrid Data 2 SD, I can move also move /data/dalvik-cache and any other folder to sdext, its only not needed, because I had after the re-odexing much more free space on /data, so I did moved dalvik cache back to the NAND from the sdext, before re-odexing I moved dalvik cache to sdext, becaue it was needed for running ~100 apps.
short form:Only Theming is impossible with a re-odexed rom
Hope you'll understand this now.
Edit: Can someone help me for creating a update.zip for re-odexing. It must only copy the dir odex to /data/local/tmp/odex , chmod 755 them all and execute the shell script /data/local/tmp/odex/odex
Sooo
if i get ADB access using windows i can skip step 2 in option1 right?

No. You need to reboot in cwm and try to get adb access from there. Windows adb in recovery never worked for me, you need linux to get adb access from cwm mode

Right, I tried to make a update.zip which execute the script, but i had no success, it would be great if somebody can help me.

ADB actually works for me, just ran cmd.exe using admin privileges and i ran the odex script it worked, odexed ALL my system files, cleared my /data/dalvik-cache/
But like TearsDontFalls said it doesn't show the free memory correctly,
Im running g3mod and im yet to try the option4 that asks you to switch file systems
And the /g3mod.log says,
st17: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
While the other partitions are all clean,
How did you got adb access in windows? Sure you was in cwm recovery while re-odexing?
Finally, someone post a guide on this. And it works! Though titanium backup never worked for me. And is it necessary to run the script on cmw? Cause I didn't done it on cmw.

I didn't expect that it works on a running system, but it can be so, so I'll update the guide after Christmas.

It worked perfectly for me,
I tried going to the G3 kernels recovery, ADB just wouldnt connect,
so i turned it on, Ran the script when it was in standby mode , then it gave an error at first,
Which i rectified by making the /system read or write using root explorer,
I think i ran the script using admin privileges.
Dont remember..
And g3mod.log showed me this
Code:
Checking mmcblk0p2
/dev/block/mmcblk0p2: clean, 11/125488 files, 15840/500173 blocks
Checking stl6
/dev/block/stl6: clean, 1302/13600 files, 46914/54400 blocks
Checking stl7
/dev/block/stl7 contains a file system with errors, check forced.
/dev/block/stl7: Inodes that were part of a corrupted orphan linked list found.
/dev/block/stl7: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
Checking stl8
/dev/block/stl8: clean, 12/2176 files, 143/8704 blocks
Data2SD Disabled
Multi-OS Data Disabled
System detected: FROYO
System booted with Samsung Froyo kernel mode
Compcache disabled
No problems right now, But cant stop wondering why it says it is inconsistent.
I don't know why it is so, but it also doesn't show the right free space, so convert it to a other file system and then convert it back.
UNBELIEVABLE!
Finally, the first method worked for me.
Working great on HTC Amaze 4G
Thanks

Thanks for your report. So it seems to be working on other devices, so I'll create a thread in android development.
Thanks works on sense 3.5, but I had to change Bootclasspath from the boot.img and add missing files below in odex script.
great guide
edit: now searching on how to re odex a single file.
Yaa...I know. you can find a lot of tweak in this forum. I just want to share the tweak I've made for you. this tweak is an enhanced version this old tweak http://forum.xda-developers.com/showthread.php?t=1714217. that tweak is for GB. I'm not recommend you to install that stuff to your system. if you're using ICS device, especially Xperia one, you can use this tweak instead.
all the files could be downloaded here:
v_0.1 : http://www.mediafire.com/?c4ua4cwwd0e774j
v_0.2 : http://www.mediafire.com/download.php?9ua4lz8wafqq79w
v_0.2.1 : http://www.mediafire.com/download.php?2bqcgbkt01banl6
(this latest update only contain add blocker tweak. you need to copy the hosts file into /system/etc to install it.)
sorry, no flashablel zip file yet, since we don't have working cwm at this moment.
PRE-REQUIREMENTS
1. rooted device
2. init.d support system
3. busybox with symlink installed
if you don't have a rom with init.d support, you can made it by yourself. simply create file named "install-recovery.sh" in /etc. and put these stuff inside that file
Code:
#!/system/bin/sh
# init.d activation script
busybox run-parts /system/etc/init.d/
to test your init.d script you can made a simple script in init.d contain
Code:
#!/system/bin/sh
# test code
touch /data/tes_kucing.log
echo "kucing meong" > /data/tes_kucing.log
if it succes, you'll find tes_kucing.log in /data after you reboot your device.
WHAT INSIDE IT?
this tweak consist of several parts.
1. kuro1 tweak - system tweak
2. kuro2 tweak - prop tweak
3. kuro4 tweak - sound enhancement
4. local.prop tweak
5. zipalign tweak
all the details about the tweak is already inside the tweak files.
HOW TO INSTALL
simply copy all files into their respective folders and give them rwxrwxrwx permission. after that type these command in your terminal
Code:
su
rm /data/dalvik-cache/*
reboot
after boot, check /data and see if you could find all the log files. if you got any problem, you can report here and show me the log files.
CHANGELOG:
v_0.2.1 (2-1-12):
- add blocker.
- this is a little addition for v_0.2. you need to install v_0.2 then copy hosts file to /system/etc to use the complete tweak.
v_0.2 (9-12-12) :
- new optimized script
- auto root for blast tool. no need to type su. just type "blast" in your terminal and the script will run with root permission
v_0.1 :
- initial public release

GPS tweak
this tweak will make your gps acquire your postition relatively faster. to install it simply replace your gps.conf with this one and reboot. http://www.mediafire.com/download.php?vdkrzx55qkzqn27
please note that this gps.conf file is optimized for indonesian region. I'll show you which part I modified from the original one so that you can optimize your gps according to your country.
Code:
# more ntp server
NTP_SERVER=id.pool.ntp.org
# the line above is the ntp server for indonesia. you can replace it with your region id. the form will be <country code>.pool.ntp.org
NTP_SERVER=asia.pool.ntp.org
NTP_SERVER=europe.pool.ntp.org
NTP_SERVER=africa.pool.ntp.org
NTP_SERVER=north-america.pool.ntp.org
NTP_SERVER=south-america.pool.ntp.org
NTP_SERVER=oceania.ntp.org]
I also modify this part
Code:
# Intermediate position report, 1=enable, 0=disable
INTERMEDIATE_POS=1
# that line above is to enable intermediate position report. less accurate but faster gps lock
# Accuracy threshold for intermediate positions
# less accurate positions are ignored, 0 for passing all positions
# orig 5000
ACCURACY_THRES=100
# this line define the accuracy threshold if you activate intermediate position. If I'm mistaken the value is written in meter. less number means more accurate position, longer gps lock. while higher number means faster gps lock but less accurate position. you can modify this value on your own.
can you make a flashable since we have recovery for a few days now? im gonna test if it works.
Until there's update for this stuff there won't be any flashable zip. I know, its not convenience to copy the files one by one but I need to make sure the filesgot copied into system. Last time I checked into cwm thread there's a report about problem when install a flashable zip.

Does that affect headphones volume which is not the best on stock? I'm sure the headphones volume is limited on purpose and I'm looking to boost it up since none of the Google Play volume boosting apps work on ICS and above.
i'm afraid not. the sound enhancement tweak is used to enhance the sound clarity, not the headphone volume. if you want a louder volume on your headphone you can try using eq app like the one in my beat bass app thread. try the latest one.
thread updated with add blocker tweak.
