[HOW TO][Windows]Extract Deodex Sign and Zipalign an official ROM

Hi,
Just want to share tools I found in order to :
- Extract SGS2 stock firmwares :
* Use sgs2toext4.jar Application from drphrozen to convert .img files to ext4.img
* Then MOUNT ans EXTRACT ext4.img with Diskinternals Linux Reader : Here
- Deodex, sign and zippalign :
with this deodex kit : _Kit_Deodexage.zip
- Create your CWM customROM (wype script)
using a Skeleton ROM : Custom_ROM GS2 by SicOpaT.zip

Nothing from me, just reporting for you
Links at the end of post (or in changeLog)
EDIT 16/08 :
1/ update of Kit_deodexage with last versions of smali/baksmali v1.2.7 to avoid LAG bug of browser
2/ add of Custom_ROM GS2 by SicOpaT_v2.zip with a new CWM script NON WIPE
To customise the CWM script, go to Custom_ROM GS2 by SicOpaT.zip\META-INF\com\google\android and edit updater-script with notepad ++
Step by step guide ​:
Preparation :
1/ Extract Custom_ROM GS2 by SicOpaT.zip in order to have a folder with the same name (your future customROM)
2/ Extract sgs2toext4.zip to sgs2toext4.jar and put it in C:\
3/ Extract _Kit_Deodexage.zip to a folder of the same name
4/ install Diskinternals Linux Reader : Here
5/ Install Java SE Development Kit (JDK) if not already installed : Here
Click to expand...
Click to collapse
Extracting the stock ROM :
1/ open your stock__firmware.tar with 7-zip or winRAR
2/ extract in C:\ :
factoryfs.img,
cache.img (if you have 3 tar files in your firmware, extract cache.img from CSC.tar)
modem.bin
zImage : your kernel
Click to expand...
Click to collapse
* Extracting KERNEL and PHONE part :
3/ put zImage and modem.bin in the root folder of : Custom_ROM GS2 by SicOpaT (next to META_INF)
Click to expand...
Click to collapse
* Extracting Factoryfs.img :
4/ Double click sgs2toext4.jar, a windows is opening :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
5/ drag factoryfs.img in the sgs2converter.jar windows
factoryfs.ext4.img is created
6/ Open Diskinternals Linux Reader
Code:
> Drives > Mount Image > browse to your factoryfs.ext4.img > Mount
Then a new drive appears in the Diskinternals window, called Linux native Volume > double click on it
7/ Select all and press Save > Next > Browse to Custom_ROM GS2 by SicOpaT/System/ check for Save directory structure and then press Next > Next > Finish
8/ In Diskinternals click Back and then right click to your Linux volume and select unmount
Click to expand...
Click to collapse
* Extracting cache.img :
9/ Double click sgs2toext4.jar
10/ drag cache.img in the sgs2converter.jar windows
cache.ext4.img is created
11/ Mount cache.ext4.img in diskinternals
12/ In your linux drive goto \recovery and save sec_csc.zip
Don't save it in your Custom_ROM GS2 by SicOpaT folder
13/ Extract sec_csc.zip (same structure as an update.zip)
14/ Copy everything in /system exept /app to Custom_ROM GS2 by SicOpaT/system
like here :
Now you can unmount and close diskinternal, we have done with extracting the ROM
Click to expand...
Click to collapse
Now time to Deodex, sign and zipalign : with the _Kit_Deodexage script
1/ in Custom_ROM GS2 by SicOpaT/system/ MOVE everything in the app folder to _Kit_Deodexage/app
3/ in Custom_ROM GS2 by SicOpaT/system/ MOVE everything in the framework folder to _Kit_Deodexage/framework
4/ Press : Deodex_Gingerbread.cmd and it will
- deodex
- sign
- zipalign
4 bis/ edit after beginning of deodexing process the NePasSigner.txt and add samsung apps
5/ 2 folders are created : Deodex_framework and Deodex_app
6/ verify that the /app and /framework folders are empty
6/ Move everything from /Deodex_framework exept java.awt.jar to Custom_ROM GS2 by SicOpaT/system/framework
7/ Move everything from Deodex_app to Custom_ROM GS2 by SicOpaT/system/app
Click to expand...
Click to collapse
Buid your CWM update.zip :
With WinRAR : CTRL A in your custonROM root folder and Right Click > Add to Archive > ZIP and None or Normal compression
Click to expand...
Click to collapse
That's all ! You have a stock customROM fully deodexed, signed and zipaligned
PS : You should change the Kernel for the CF-Root Kernel (CWM Manager ...) changing the zImage with the zImage from ChainFire CF-Root
PS 2 : You can add some apps (like Titanium backup) in the /data/app folder of your customROM
EDIT 1 : The deodexed browser.apk obtained will be bugy : Lag scrolling
Since pulser_g2 found the FIX, DEVs used an old deodexed browser.apk (from KE2 ROM for example).
So pulser_g2 foung the FIX, in order to avoid this Lag trouble using the last deodexed browser.apk (KF2 for example). You can see the How To FIX yourself the laggy browser.apk following advices from pulser_g2 in the changeLog of 07/03/2011.
EDIT 2 : just added a zip of an META_INF folder witch can be used for update over a previous deodexed customROM with same signature (a previous ROM built with the same script).
With this META_INF, you will not loose any data/cache

ChangeLog of the HOW TO :
07/04/2011 :
* Switch bugy sgs2converter.jar to new sgs2toext4.jar from drphrozen
* Re-Add the Convert_sgs2img.exe tool to extract .img to .ext4.img (end of post)
CMD command :
Code:
Convert_sgs2img.exe factoryfs.img factoryfs_ext4.img
07/02/2011 :
Modification of _Kit_deodexage.zip in order to add the custom java.awt.jar from xeudoxus
07/01/2011 :
Add the new version of drphrozen sgs2converter.jar, available HERE
Now you just need to double click on the sgs2converter.jar, without opening any CMD promt command.
You drag and drop your stock .img file and the tool will convert it in <inputname>.ext4.img in the same folder

[/QUOTE]
BONUS :
To personalise your customROM, you can change the name of the ROM shown in Parameters > Version number :
with Notepad++, open the file "\Custom_ROM GS2 by sicOpaT\system\build.prop" and look for the line beginning with : "ro.build.display.id=" (often the 4th). Example : ro.build.display.id=GINGERBREAD.XXKF2
Replace everything after the "=" with what you want. Example : ro.build.display.id=SicOpaT's ROM KF2
Then save the file

Thanks for the infor .. but what does the " - CWM GS2 Skeleton ROM (wype script) : Custom_ROM GS2 by SicOpaT.zip" do ??
anyway of getting a step by step guide.
Thanks

I've used Ubuntu until now... Testing this one

got the same problem, i took deodexed ones from other deodexedROM

Couldn't flash using cwm (maybe battery low, don't know)
better luck tomorrow I guess

How does the script take care of the Linux file permissions in Windows?

Thanks for the info.

That was some info which i was looking for the last few weeks, but mostly ended in apps that didn't work for everything.
Gonna give it a shot tomorrow.
Thnx for the info.

very well defined and this will sure help some newcomers to build thier own custom roms. you deserve a star from me !!

Thanks for this Guide!
1.) The last step would be to put the new CustomRom Folder to a Zip and flash via CWM?
...or is it a problem with signing then?
EDIT: you have to put the files back into the original ZIP!
2.) why do we have to put cache.img and modem.bin to the customrom root folder?
Thanks

Flashed via cwm 4.0.2 -> Bootloop :/
No modifications done at the moment

No you have to put :

- modem.bin (phone part in ODIN)

I have forgotten wype.sh in the /system folder of the skeleton customROM.
The wype.sh will wype everything in the /data folder in order to prevent bootloops
I reuploaded the CustomROM GS2 with the wipe.sh

Thanks! Works now

i am running per instructions, trying to deodex KF2 rom. but i face problem at the deodex/sign/zipalign. after running the script file, there are still a lot of files in the "app" and "frameworks" directory. what am i doing wrong?
edit: 2nd round works, no idea why?? but left email and mobileprint, and as per you suggestion get it from another deodex rom.

This is EXACTLY the thing i was looking for since getting my SGS2 this week.
Wanted this since the Hebrew/RTL routine fixing i did on other devices needed deodexed ROMs to work (modifies framework.jar/libwebcore.so).
I'll give it a shot today or tomorrow and report back.
Either way, THANK YOU very much for the effort!

I know this is a stupid question, but where can i find my factoryfs_out.img iv done the cmd bit but cannot find the factoryfs_out.img to mount??

[HOW TO] Change/Modify Secondary Splash Screen Initrd/logo.rle

}
I cant bellieve how hard it was to find any info on this topic
I was working on my rom and wanted to change the secondary splash screen image.
I searched around, asked devs and had no success finding a step by step tutorial on how to do this.
Finally after much research I did it! so here i bring you my experience.​
Click to expand...
Click to collapse
Boot order
​
1. To modify/change the first boot image go here:
http://forum.xda-developers.com/showthread.php?t=895089
2. To modify/change the bootanimation go here for some examples:
http://forum.xda-developers.com/showthread.php?t=1129705
Click to expand...
Click to collapse
First we need to establish where this splash image is located,
the image file is called logo.rle and is located here:
(i used 7-zip to view but don't use it to modify)
This is the file we need to change/modify, you can extract it with 7-zip.
Now we need to be able to convert this logo.rle to .png and back to a logo.rle
​
To do this go here:http://forum.xda-developers.com/showthread.php?t=1140406​
Code:
1.run command promt
a.browse to folder with those bat files
-type:cd \users\you\desktop(if located on desktop)
-copy logo.rle to this folder
b.to conver rle to png type: Convert_rle_to_image.bat logo.rle
c.to convert back to rle type: Convert_image_to_rle.bat logo.png
Click to expand...
Click to collapse
If you have your logo.rle ready now we need to replace the one that came in your initrd.gz
this is harder than i thought, because initrd.gz is a image file it cant be modified with 7-zip
first you will need to be running linux (im running ubuntu on a virtual machine)
once you get linux create a new folder on the desktop called "temp" copy
the initrd.gz to this folder, open applications/accesories/terminal
and browse to the temp folder with the initrd.gz file(mine is "cd /home/isidro/Desktop/temp)
now type
Code:
gunzip -c ./initrd.gz | cpio -i
now in the temp directory you have unpacked initrd.gz. Replace logo.rle then when you're done still in the temp directory type:
Code:
find ./ | cpio -H newc -o | gzip > ./initrd.gz
this will replace the initrd.gz with the modified logo.rle
​
Click to expand...
Click to collapse
Now just Copy/Replace the modified initrd.gz to your Rom's boot folder and Test!
This worked for me on the HD2 but I would assume it works on any android Rom. Keep in mind this is the best way I could do it, if you know of a better way please share.​

nice compilation...thanks bro

nice work bro
really
but I hope there i some easier way to do it
cuz this involves linux and virtual machines and I dont think many of us have this

Been looking for this for a while now, thank you very much !

very clear! i search for this a long time
THX bro

nice to see some dev sharing their knowledge ...thanks bro

If anybody cant get this to work at all!!!
send me your initrd.gz and your new image and ill give it a go.

thanks for taking so much time for making this excellent article. thanks added.

Excellent tutorial!! Very time consuming process for changing just one image but definitely easy when given step by step instructions.
Thank you for all your hard work and effort!

Ok, please tell me what am I doing wrong- I want to replace the logo.rle from one initrd.gz to another initrd.gz
I extract both with gunzip -c ./initrd.gz | cpio -i into their own separate folders
I copy the logo.rle I want over the logo.rle I want to replace
I do find ./ | cpio -H newc -o | gzip > ./initrd.gz after ensuring the old initrd is not there in the folder
I flash it on my phone, and it wont boot - if I flash same the initrd.gz without replacing the logo.rle, all is fine. I have tried this so many times

works perfect
10x

works nice. thanks.
you know what's nicer?
removing the logo.rle completely.
and what's even nicer than that?
finding the way to do it to clk boot.img
(how to patch it's initrd.gz or kernel)
then what you get is the First Boot Screen (HSPL) and then boot animation directly.
I can find a way to unpack the boot.img and repack it successfully.
If you find this out, that would be great.
Should be possible to do on linux, but I get a corrupted boot.img every time i try.

Is there any way of changing this after the ROM is installed? Unfortunately the ROM I use requires that you flash a kernel .zip after installing it, which then resets the second splash screen.

open the update_kernel.zip with 7zip
replace the initrd.gz with the one with the new image, now just flash
the kernel and that's it

There is guide for change it use Window OS:

Unfortunately though, that doesn't seem to work. It's got a boot.img, so I had to extract that first in Linux, then I replaced logo.rle and recompiled boot.img. I then replaced the old boot.img in the kernel zip file and attempted to flash it, and I can't remember what happened. Either I got a message about update-script being deprecated and was told that installation was aborted, it flashed fine but didn't work, or it stopped my phone working.
tl;dr: I've spent far too long trying to figure out that one little image and in the end decided to just change the first splash screen to match the second one that flashes with the kernel.

I've follow all your staff and when I repack the initrd.gz with ubuntu I get this message error ( in french the message error so I try to translate) : cpio : the file ./initrd.gz is bigger, 163840 new bytes does not have been copied
That is the problem

Yeah I know it says it's not copied but it is just test the initrd after that

[KERNEL]How to build a custom Android Kernel for your device

here is the guide
http://forum.xda-developers.com/showpost.php?p=24747881&postcount=4
thakz irfanbagus for the guide

where's the package link?have you try this guide by yourself?

i hope he tried
got a ubuntu, i will try this one (cross-fingers)

it's not working. sgy stock kernel do not have /proc/config.gz and gcc version in arm-2011.03 not compatible with other precompiled module.
this is work for me
requirement :
1. linux box 32 bit with working gcc. you can use real linux machine or virtual machine
2. Sourcery G++ Lite 2009q3-68 toolchain for ARM EABI from http://www.codesourcery.com/ (Linux version without installer arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2)
3. mkbootimg with md5support. got it from http://forum.xda-developers.com/showpost.php?p=22224170&postcount=241 . credit to harish2704
4. split_bootimg.pl (google it)
5. kernel source from http://opensource.samsung.com . i use GT-S5360_GB_Opensource_Update2.zip
6. stock boot.img (or from your custom kernel).
step :
1. make folder "sgy" in your home. the result is folder "/home/<yourname>/sgy". <yourname> is your linux user name, and from now replace <yourname> with your user name. put all file you already download there
2. extract "GT-S5360_Kernel.tar.gz" from "GT-S5360_GB_Opensource_Update2.zip". put also in "sgy" folder
3. open terminal emulator and go to your working path with command
Code:
cd ~/sgy
4. extract your compiler with
Code:
tar -xvf arm-2009q3-68-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
5. create folder "kernel" and extract kernel source there
Code:
mkdir kernel
cd kernel
tar -xvf ../GT-S5360_Kernel.tar.gz
you got 2 folder, "common" and "modules"
6. open folder "common", there is file "Makefile". open with text editor and find line with content "/opt/toolchains/arm-eabi-4.4.3/bin/arm-eabi-". replace with "/home/<yourname>/sgy/arm-2009q3/bin/arm-none-eabi-", don't forget replace <yourname>.
7. in terminal goto folder "common" and load default config for sgy
Code:
cd ~/sgy/kernel/common
make bcm21553_totoro_05_defconfig
8. if you want change you config run
Code:
make menuconfig
9. if you ready to build then run
Code:
make
or if you have dual core cpu and want to make it faster
Code:
make -j3
10. when complete and no error appear, copy your kernel to "sgy" folder
Code:
cp arch/arm/boot/zImage ~/sgy
11. extract ramdisk from your boot.img
Code:
cd ~/sgy/
perl split_bootimg.pl boot.img
you got "boot.img-kernel" and "boot.img-ramdisk.gz". move "boot.img" and "boot.img-kernel" to other place.
12. repack your new kernel and ramdisk. but first get md5sum of your new kernel
Code:
md5sum zImage
you got something like
Code:
1fd319aa60abc2abae2e5932bcb9fc77 zImage
you need that "1fd319aa60abc2abae2e5932bcb9fc77" write it or copy to text editor. you need run it every time compile new kernel
13. repack
Code:
chmod +x mkbootimg
./mkbootimg --kernel zImage --ramdisk boot.img-ramdisk.gz --base 0x81600000 --kernelMD5 <your md5sum result> -o boot.img
14. make odin flash-able
Code:
tar -cf boot-sgy.tar boot.img

i don't call it fake. it's just too general and missing some detail (but critical) for our device. and in the 'spirit of operation iron fist', i think it's better to put here

with my internet connection, it will take weeks just to download the source. and i think cm, like android source, use repo. so you can't just download it. you clone it from their source repository, that mean no download accelerator.
btw beside kernel source, samsung also release their mod to android source. but to build it, you still need to get android source (about 10GB according their website).

well...thats your choice, irfan.
@sgy.creed: sorry, I don't mean to offend you. IMHO it will be nice if before someone post any guide they already have tested it by them. in this way, they'll able to give more accurate direction to anyone who need their guide. as we already know, kernel is crucial part in our device. any mistake in compiling it will lead to brick our device. we have to cautious on it. peace ^,^v

GT-B5510
Is there by chance anyway to find a stock Kernel for my device for my GT-B5510???
I recently flashed a custom Kernel for GT-S5360 and the result was a Brick.
is there someone willing to help me??

Have u tried through kies?if the answer u failed then only odin is the way.
u need pda files from the update.Search google,i found one FW but it is from Italy :

Hi guys,
This guide teaches how to make a new kernel for your device, it works in most of the cases but doesnt mean it will work for everyone
You need a minimal linux experice to know WTF you are doing
If you have any questions, post Belloowww
Download the required files
You will need a linux machine with the basic development tools or a virtualbox machine running a linux distribution (ubuntu 64bits will do fine)
I use the codesourcery package
Download the IA32 GNU/Linux TAR
The tar package is the easier to install
You will also need your kernel source from your manufacturer, for samsung the sources are available here
Install the cross compiler
Enter the folder were you downloaded the package and extract it, you will get something like arm-2011.03
Move that folder to some location, i use opt
ex: mv arm-2011.03 /opt/
or
sudo mv arm-2011.03 /opt
Done!
Extract and prepare the kernel sources
I will use the samsung sources as example, but anything can be used
For the samsung sources, after you extract the zip, you will get something like DEVICE_Platform.tar and DEVICE_Kernel.tar.gz
Extract the kernel:
tar zxvf DEVICE_Kernel.tar.gz
Enter the kernel folder and list the folder contents
ls
The structure is something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Most devices contain the config file inside the device
You can extract it like this:
adb shell
su
cp /proc/config.gz /sdcard/
exit
exit
adb pull /sdcard/config.gz
Good, now we have the sources, compiler and configuration
Compiling the kernel
To compile ther kernel, i usually clean the sources first, with this i know for sure nothing will go wrong (usually )
make ARCH=arm CROSS_COMPILE=/opt/arm-2011.03/bin/arm-none-eabi- distclean (Remember to replace acordingly the compiler folder)
Sources cleaned, time to load the config file
gunzip config.gz
cp config ./.config
Good, now lets check the menuconfig (menuconfig is a menu to choose the kernel options, created to make it easy to select)
make ARCH=arm CROSS_COMPILE=/opt/arm-2011.03/bin/arm-none-eabi- menuconfig
Change whatever you want and exit and save
good, now its time to build
make ARCH=arm CROSS_COMPILE=/opt/arm-2011.03/bin/arm-none-eabi- -j2
Now wait for it to finish!
Your compiled kernel will be located inside arch/arm/boot/zImage
Extracting a boot.img
Good, now we have the zImage, but WTF to do with it?
Well, android usually (some samsung devices use a different boot.img method, ex: I9000) has the boot.img, inside of it we contain:
- ramdisk (required files to load the /system partition and continue the boot sequence)
- zImage (our kernel)
- pagesize
- base
- cmdline (some kernel paremetes used on boot)
To create your own boot.img, you need one from a nandroid backup that was made from CWM or AmonRA custom recoveries (there are other methods, but for those use the madteam forum )
The boot.img is located inside your /sdcard/clockworkmod/backup/somedate/boot.img
You will also need the unpackbootimg and mkbootimg binaries, i this link there is the 64 bit version (wont work on 32 bit linux)
create an empty folder, copy the downloaded file inside, enter it and do:
tar zxvf bootimgtools.tar.gz
chmod 755 *
now copy the boot.img you got from the backup
and extract the boot.img with:
./unpackbootimg -i boot.img
this will create the files as explained above
Creating the boot.img
Before making the boot.img, we need some information from the files extracted
cat boot.img-base ( save the output #1)
cat boot.img-pagesize (save the output , place the value inside the Hex Value of this site, and copy the decimal value and save it #2)
cat boot.img-cmdline (save the output #3)
Good, now copy the compiled kernel (zImage) inside the current folder and do:
mkbootimg –kernel zImage –ramdisk boot.img-ramdisk.gz –cmdline “(replace with output#3)” –base (replace withoutput #1) –pagesize (replace with output#2) -o /tmp/boot.img
Good, the boot.img is created!
Now test on your device!
If you dont know how to flash the boot.img, enter the madteam forum and request help (its too difficult to explain the flashing of boot.img if you dont know how to do it )
Take care!

Kies said that I had the most recent firmware, tough I found some new versions.
right now trough kies I tried to do an emergency firmware restore, i guess thats the name, but it asked for a code, a 4 number code i guess and i dont know what's the code.
Via odin I tried to install stock firmware from sammobile but it failled as well, if you want I'll post the dialog from odin.
I can boot in recovery mode, Odin(download) mode and CWM mode.
could you point me in the right direction???

I was just wondering if you went to the oldest possible firmware you could find and then proceeded to update from that. Sometimes the updates only contain necessary info and kind of rely on the previous installs.

[Tutorial] Decompiling-Compiling-Editing APKs

Hello guys. I'm creating a thread with a simple tutorial of how to decompile, compile, edit apks. I've seen some threads about it, but all of them were very complicated to understand. It's a simple tutorial, not designed to really mess with apks, just to edit a bit, like swapping icons, images, etc. When I get some more time, I will also teach how to mess with some CM9 Theme Chooser APKs
First of all, what you are going to get with this?
1. Decompile APKs
2. Decompiling all files, so you will only get XML [easy to edit], images and SMALI files [in most cases]
You need to know...
1. Works only Windows [x86 or x64] [You can try on linux, but you will need to download other files of apktool. But the steps are almost the same]
2. Choose the .bat of your version. [x86 = 32 bits] [x64= 64 bits]
3. You need JRE
4. Attached, the most updated apktool.
Let's go...
STEP 1 - preparing
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1. I've optimized the files to run at D:\apktool [Another partition]. So, extract the .7z, and make sure that there's a apktool folder at the ROOT of D:\ drive. If you want to put this folder at other place, please pay attention: open the Run [x??].bat on the notepad. If you want the folder at the C:\ drive, delete the "D:" line, and swap the directory to the one you choose. [Example: "C:\Users\....user name....\Desktop"] Just make sure you included the cd before the path. If you want the folder at other place on D:\ drive, just change the directory [Example: "D:\Desktop"], and again, with the "cd" command before the path.
STEP 2 - still preparing...
1. Get framework-res.apk from your ROM [if you are on a Samsung ROM, also get twframework]
2. Extract framework-res.apk here
3. Open the correct .bat of your Windows version
4. Run this command: "apktool if framework-res.apk" [if you are on a Samsung ROM, also do with the other framework]
STEP 3 - now decompiling
1. Now, put the apk you want to edit on your apktool folder.
2. Run this command: "apktool d APK-NAME.apk
3. You may get NO errors when it's done.
4. The out put folder is the folder of the decompiled apk.
STEP 4 - now compiling
1. Run this command: "apktool b APK-NAME" [without the .apk]
2. You may get NO errors when it's done.
3. The output APK is located on \[apktoolfolder]\APK-NAME\dist
STEP 5 - optimizing
1. Sign your APK with this
2. Zipalign your APK with this. You can also use zipalign scripts on your ROM to zipalign.
3. Now you may install your apk normally. [user app or system app]
__________________________________________________ __________________________________________________ ___________________________________________
TIPS
1. You can edit .smali files with Notepad ++
2. You can also edit XML files on the Notepad [Windows notepad. I think that with Notepad ++ also works]
3. Soon, I'm going to teach how to edit CM9 Theme Choose APKs. You will be able to: theme non-themed apps, and replace images.
4. I tried to be the most clear and direct as possible. If something is unclear, tell me now. If you have any suggestions to make the tutorial better, please tell me...

This is a lot harder. Can't do this for you. This isn't playstation2 with it's football games. Sorry. If you still want to try, decompile and search for images to replace.

Hi,
a question here:
I was succefull to theme system apps, but when I try to theme a normal, it never works. all the processes goes fine, but when i eant to install modified apk it gives error. and even when I copy it to /data/app/ it disappear from app drawer.(after restart of course)

First: Great Job
Second 2 Questions.
Is it not easyer to editing in .java (with dex2jar tool) then in smali?
For beginners is it not a little bit easyer to use "Apk One Click" for de- and recompile .apk (include the dex2jar Tool) ?

Thanks. When you decompile, it will turn a lot of files into .smali files. Those smali files are very easy to modify on Notepad++. But I'm going to study more about dex2jar.

[Tutorial] How to change kernel logo (1st boot srceen) [COMPLETED]

We have 3 major works here... So I gonna to make it seperated
-1st post is HOW TO EXTRACT kernel.img (boot.img)
-2nd post is HOW TO CONVERT PICTURE FILE to BOOT.RLE
-3rd post is HOW TO REPACK THE KERNEL PAKAGE into boot.img
Requiredment
-Window machine
-installed cygwin
-the full boot.img/kernel (some kernel won't work because there is no full pakage/ i mean we can't)
-bootimg.zip (tool for UNPACK and REPACK kernel)
-boot_screen_logo_creation_package.rar
Thank and Credit
i- Credit to DooMLoRD Recognized Developer over most of XPERIA devices for his own tool and tutor that I learned before
ii- Credit to jimbo77 Senior Member for his tutorial that I used and learned and tool for unpack and repack
ii- Don't forget to give them a thanks meter
=============================================================================
Here we go
1-This section I will show u how to unpack and repack the boot.img
just see from original thread by jimbo77 from here and download the UNPACK and REPACK tool by him HERE
this is a fast guide from me:-
1-extract the bootimg-tools.zip into new folder (name it 'boot' folder)
2-move it into cygwin directory (cygwin/boot)
3- move your fav kernel into same directory
4-run cygwin.bat
cd /boot
Click to expand...
Click to collapse
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
5-Now, unpack your boot.img by running the following command:
./extractboot boot.img
Click to expand...
Click to collapse
If your output looks like this, then the extraction has worked correctly! Note that the Command Line string has also been read from the source file, this will be used later when you go to re-pack your file.
Your script folder should now look like this:
boot.img-kernel is the compiled kernel blob that was inside the source boot.img, if you want to replace the kernel with another compiled kernel image, you can replace this file with another one (but leave the file name the same)
boot.img-ramdisk.gz is the gzipped ramdisk image which has been split from the boot.img, you should leave this file alone.
The “out” folder contains the EXTRACTED ramdisk, and this is where you should make your changes to the ramdisk.
Important Note!
Remember, when editing files in the ramdisk through Windows, such as init.rc, Windows notepad will not format the files correctly, making them almost impossible to read, wheras Wordpad will LOOK like it is formatting the files correctly, if you save one of these files from the Wordpad application it will BREAK the file and it will no longer be able to be read correctly by Android. To edit these files you MUST use an editor such as Notepad++ which you can download for free.
AGAIN...
Special thanks/credit to jimbo77 for his excellent guide

So.. NEXT step to change a kernel logo is here
Requiredment
1-a picture what are u like to look into the 1st boot screen (kernel logo) (make sure it size/resolution same your device resolution)
2-boot_screen_logo_creation_package.rar
3-some infos and knowledges here
4-window machine like i explained on 1st post
My quick guide
-extract the tool.rar
-move extracted files into new folder (name it 'rle' folder without quote)
-move into cygwin folder (to make it easy to follow my simple guide)
-copy your own logo.png (a picture u want to use on a kernel) into same rle folder
(for 4 steps above it shold look like tis)
-now launch cygwin.bat
cd /rle
Click to expand...
Click to collapse
./convert_image_to_rle.bat logo.png
Click to expand...
Click to collapse
Ah...my mistake..don't forget to move/copy/replace new logo.rle into
C/cygwin/boot/out/ramdisk/here
if you done good...follow next step on next post (to repack your moded kernel)

Last step before you flash a new look kernel (boot.img) is
Repack your moded kernel
./packboot
Click to expand...
Click to collapse
One thing to note that people may mention in other guides, is that when packing boot.img files, you will usually have to declare a base address, and a command line to the packaging tool. This set of scripts reads the existing command line and base address from the boot.img file you originally provided at the time of repacking, so always make sure you leave your original source boot.img file in the folder and do not re-name it after extraction, your newly created boot.img file will be named boot_new.img and will NOT overwrite the original.
Done! If your screen looks like the image above, then you should now have a freshly created boot_new.img file, ready to be flashed to Android for testing, you can now go ahead and flash it through FASTBOOT one thing I'll recommend though is to first do

I need this for an extra (extra thanks..)

Well I've been scratching my head about this and just can't work out what's going wrong - after I run the ./extractboot boot.img command I keep getting the message: './extractboot: ./split_bootimg.pl: /usr/bin/perl: bad interpreter: Permission denied
./extractboot: line 17: cpio: command not found
gzip: ../../boot.img-ramdisk.gz: No such file or directory'
I followed your instructions as below:
1-extract the bootimg-tools.zip into new folder (name it 'boot' folder)
2-move it into cygwin directory (cygwin/boot)
3- move your fav kernel into same directory
4-run cygwin.bat
When you say "move your fav kernel into same directory", what do you mean? Move it into the 'boot' folder? Or do you mean the 'cygwin' folder?
Any help you could give would be greatly appreciated - confused.com!

Hey Guys,
If you get this error:

./extractboot: ./split_bootimg.pl: /usr/bin/perl: bad interpreter: Permission denied
./extractboot: line 17: cpio: command not found
gzip: ../../boot.img-ramdisk.gz: No such file or directory
you need to install Perl & cpio packages. Just run the installation of cygwin again and choose them.
The problem is, now i get the following error:
Code:
./extractboot boot.img

thank you for your n00b-friendly tut., but for some reason it already goes wrong in step 1, 'cause when I extract the kernel the folder out/ramdisk remains empty, so nothing to replace. Have I done something wrong or is my Arc S just not suitable for this sort of tinkering?

I think you should install perl (for splitting bootimg) and cpio (to create ramdisk.gz ) packages from cygwin.
without this packages, extractboot script will just create an empty ramdisk folder.

ok, found "perl" but for "cpio" I searched and installed the 3 items that had "cpio" in 'em (on top of my head "default '& "items" and a third I can't remember).
If it works the OP should add that info to the tut.
