How to Deodex Rom and >odex back
Things nEeded
Code:
backsmali.jar
* smali.jar
* custom java.awt.jar
* dexopt wrapper
* recent version of busybox
Download this
Open CMD CD to folder extracted those scripts and type
1 Deodexing Framework files-
Code:
java -Xmx1024m -jar baksmali.jar -c :core.jar:bouncycastle.jar:ext.jar:framework.jar:android.policy.jar:services.jar:core-junit.jar -x android.policy.odex
(i am taking android.policy.jar as example , if framework.jar or whatever just change 'android.policy.jar' to 'framework.jar' and 'framework.odex'
This will make out folder
now smali that out folder by
typing
Code:
java -Xmx1024m -jar smali.jar out -o classes.dex
in CMD
HTML:
open android.policy.jar with 7zip without extracting
push the classes.dex created in the 7zip window in the root folder
close the 7zip windows and here is your deodexed android.policy.jar
2 Deodexing any App file i am taking systemUI.apk as example
Code:
java -Xmx1024m -jar baksmali.jar -c :am.jar:android.policy.jar:android.test.runner.jar:bmgr.jar:bouncycastle.jar:com.android.location.provider.jar:com.google.android.maps.jar:com.samsung.device.jar:com.yamaha.android.media.jar:core.jar:core-junit.jar:ext.jar:framework.jar:ime.jar:input.jar:java.awt.jar:javax.obex.jar:libvtmanagerjar.jar:monkey.jar:pm.jar:sec_feature.jar:seccamera.jar:sechardware.jar:secmediarecorder.jar:services.jar:sqlite-jdbc.jar:svc.jar:twframework.jar -x SystemUI.odex
Again out folder created now make it smali
by typing
Code:
java -Xmx1024m -jar smali.jar out -o classes.dex
in CMD
open SystemUI.apk with 7zip without extracting
push the classes.dex created in the 7zip window in the root folder
close the 7zip windows and here is your deodexed SystemUI.apk
Click to expand...
Click to collapse
3 Now we will learn to odexing back
1/ backup your original files (apk jar and odex) to /sdcard/Mod/
2/ copy modified deodexed files (.apk and .jar) in /system/framework/
3/ open a CMD prompt in the folder of adb.exe (usualy /android-sdk-windows/platform-tools/)
4/ type command :
Code:
adb shell
su
## for .JAR file :
dexopt-wrapper /system/framework/XXX.jar /system/framework/patched_XXX.odex /system/framework/core.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar:/system/framework/core-junit.jar
response must be :
--- BEGIN '/system/framework/android.policy.jar' (bootstrap=0) ---
--- waiting for verify+opt, pid=7194
--- would reduce privs here
--- END '/system/framework/android.policy.jar' (success) ---
## for .APK file :
dexopt-wrapper /system/framework/XXX.apk /system/framework/patched_XXX.odex /system/framework/core.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar:/system/framework/core-junit.jaradb shell
su
## for .JAR file :
dexopt-wrapper /system/framework/XXX.jar /system/framework/patched_XXX.odex /system/framework/core.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar:/system/framework/core-junit.jar
response must be :
--- BEGIN '/system/framework/android.policy.jar' (bootstrap=0) ---
--- waiting for verify+opt, pid=7194
--- would reduce privs here
--- END '/system/framework/android.policy.jar' (success) ---
## for .APK file :
dexopt-wrapper /system/framework/XXX.apk /system/framework/patched_XXX.odex /system/framework/core.jar:/system/framework/bouncycastle.jar:/system/framework/ext.jar:/system/framework/framework.jar:/system/framework/android.policy.jar:/system/framework/services.jar:/system/framework/core-junit.jar
It will makepatched_apknameyouodexing file now remove (renaming) "patched_" line so it will be "apknameyouodexing.odex"
Now copy Signatures- (in same CMD)
Code:
# if not already done ...
adb shell
su
# copy the original .odex and .jar in system/framework (not .apk) :
cp /sdcard/MOD/original.XXX.odex /system/framework
cp -f /sdcard/MOD/XXX.jar /system/framework # where XXX.jar is the original odexed .jar
# give all permissions to XXX.odex files :
chmod 777 /system/framework/original.XXX.odex
chmod 777 /system/framework/patched_XXX.odex
# copy signature :
busybox dd if=/system/framework/original.XXX.odex of=/system/framework/patched_XXX.odex bs=1 count=20 skip=52 seek=52 conv=notrunc
response must be :
busybox dd if=/system/framework/original.XXX.odex of=/system/framewor
k/patched_XXX.odex bs=1 count=20 skip=52 seek=52 conv=notrunc
20+0 records in
20+0 records out
20 bytes (20B) copied, 0.002042 seconds, 9.6KB/s
Done now odex/deodex your Rom , so easy!

Modifying updater-script (found in /META-INF/com/google/android)
Open with Notepad++
Now you can see in this pic theres written 'Welcome to Cm installer....'
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

Now add
Code:
ui_print("your text anything");
Code:
package_extract_dir("system", "/system");
tells extract directory system to system (in android)
Code:
mount("system");
tells mount specific directory like u can change location to dev folder
Code:
unmount("/system");
means unmount from where you mounted ! before
Code:
show_progress(0.200000, 5);
tells us that show progress like you can see when installing Rom yellow lines comes (CWM) u can control by this. its by Seconds..
Code:
symlink("busybox", "/system/xbin/fold");
means make symbolic link to that file at folder 'xbin'
Code:
format("MTD", "system");
means format mounted system folder
Code:
delete("/data/local");
Tells that delete /data/local folder
Code:
set_perm(0, 0, 0777, "/system/bin/chka2sd");
set pem means setting permission like chka2sd permission rww-rww-rww
Code:
assert(package_extract_file("boot.img", "/tmp/boot.img"),
write_raw_image("/tmp/boot.img", "boot"),
delete("/tmp/boot.img"));
it means flash boot.img make raw file (image) at tmp/boot (afterwards android do which i dunno) and delete that file!
Now save this file
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Modifying settings.apk
Creed$ rom!

which entry? of Icon? no Icon needed!

Well its comprehensive and noob proof
Just a side note: Always mention the link to original article of any forum especially the deodexing part!
Secondly as Avilove.cullen said the tutorial for modification in Settings is incomplete as you also have to kang up the respective strings in strings.xml
And FYI we need not modify public.xml only when you put icons or images

Actually this isn't fundamental
It depends on the original developer where he defines it
In case of settings.apk it is with xml folder.

OK so say you wanted to add a list item called start clock. You would add the preferencescreen code and specify the target in settings.XML only? You wouldn't add lines to Id.XML or strings.XML and values.XML and then specify where in the layout folder of the appropriate XML in that folder?

[GUIDE] Beginners/Ref Guide to Making Roms.

Hi guys! I see many people trying to learn how to make roms, Here i show the easiest and shortest way on how anyone can begin making roms for the Galaxy S3. ​
Requirements:
Prepared CWM Stock Package.
Apktool
7-zip
Notepad ++
Setting Up, and Introduction​
IF you have downloaded firmware from sammobile instead of zoot1's package, use this part for Setting up and introduction: http://forum.xda-developers.com/showpost.php?p=37812381&postcount=33
OR ELSE THE EASIER WAY
To start with, Download the prepared CWM Stock Rom by zoot1 here: http://forum.xda-developers.com/showthread.php?t=1868004
I personally use firmware from sammobile, because i like to do everything myself. Though this method would be easier for beginners.
Extract the zip file to folder called "ROM".
Now lets head towards the customizing.
Thanks to Prawesome alot for this part. I took some info from his guide.
So now, open up the system folder. You'll find loads of folders in it. Here is a brief introduction to each of those folders:
1. apps
When you open this folder. You will find apk's. An apk is an install-able app package for any Android Device.
You can delete specific apps incase you want to delete. But take extra precautions on what you're deleting. As some apps are useful. You can add apps here as well in formats of apk's. But note, adding Play Store apps to the system/app folder is not recommended. For example you don't want Google Talk in your rom, you just have to delete the Talk.apk.
2. bin
Nothing really to mod in this folder. Full of advanced techy stuff. xD
3. etc
Here is where most of the tweaks come in. There is a folder called init.d where mods like the V6 Supercharger or multi-tasking fixes can be applied. Note! Don't add more than 1 or 2 scripts. Most of them usually conflict with each other.
In the gps.conf file, you can edit your gps info to make the gps more accurate. Pretty good guides about this, search them out.
Next is the hosts file. Devs use this to block sites from generating ads, and keeping their roms ad-free. Take a look at my DroidS3 hosts file, there are over 20,000 hosts blocked. You can use the same hosts file for your rom too.
4. Fonts
Very easy folder to understand. All you need to do here is replace ttf files, and you'll change the fonts.
5. Framework
Here is where the big mods come in. I'll explain further on about this. It contains the android.policy.jar, a useful element to add many mods. Framework-res is used to change wallpapers and theme the rom. I'll explain later.
6. libs
Contains all the libs needed for specific system apps to work. Don't mess here unless you're adding a mod.
7. Folders like csc, hdic, sipdb, wakeupdata, vendor, excetra..
These are the folders, there isn't much to do. Csc folder contains the feature.xml where some mods can be added. Search the forums for that. The rest contain multi-languages and more stuff.
8. xbin folder
Used to add scripts like busybox, dexdump, openvpn support. More like the bin folder but smaller.
9. Build.prop
Ever wondered how some roms have android 5.0, when it hasn't even released? All you need to change is the ro.build.version.release to any number you like. Even Android 20! Go change it, and fool some noobs out there. More mods can be added to this file. e.g:
Code:
debug.sf.hw=1
video.accelerate.hw=1
debug.performance.tuning=1
profiler.force_disable_err_rpt=1
profiler.force_disable_ulog=1
ro.config.nocheckin=1
ro.media.enc.jpeg.quality=100
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
ro.telephony.call_ring.delay=0
ro.lge.proximity.delay=15
mot.proximity.delay=15
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
ro.config.nocheckin=1
The codes listed above are for improving jpeg quality, saving some battery life, reducing call delay and more. Search for build.prop mods, you'll find loads of them. ​Now, a small explanation of the Meta-inf folder.
In Meta-Inf you'll find the updater-script.
Since this is aimed at beginners, I'll just show you how to change what text is shown during install in CWM.
Just edit what's in the quotes of the ui_print code in the file, and enter your own text. e.g:
Code:
ui_print("Hi, This message in quotes is displayed in recovery");
Modding!​
It's time for the modding to begin.
Get apktool from: http://forum.xda-developers.com/showthread.php?t=1755243
Now, first copy your framework-res from the /system/framework directory to where you extracted apktool files. Let's call this folder "apktool"
Open the folder apktool, press shift and right click. Click on "Open command window here". Type:
Code:
apktool if framework-res.apk
Now you are ready to decompile apk's.
I'm going to show you how to mod different files. Copy over:
SystemUI.apk
android.policy.jar
framework-res.apk
1. SystemUI.apk
Just showing you basic modding here. Copy over SystemUI.apk to apktool folder. In the command prompt, type
Code:
apktool d SystemUI.apk
After it's done, you should see a SystemUI folder in the apktool directory.
I'm going to show you how to make the status bar transparent, thanks to raubkatze for this part.
Navigate to res/layout/tw_super_status_bar.xml and change android:background to match the red line.
Code:
<com.android.systemui.statusbar.phone.StatusBarWindowView [B][COLOR="Red"]android:background="#00000000[/COLOR][/B]" android:focusable="true" android:fitsSystemWindows="true" android:descendantFocusability="afterDescendants"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:systemui="http://schemas.android.com/apk/res/com.android.systemui">
Save and close.
Then navigate to /res/values/drawables.xml
Edit to match:
Code:
<item type="drawable" name="status_bar_background">[COLOR="red"][B]#00000000[/B][/COLOR]</item>
That's it. Save and close.
Go back to your command prompt and type
Code:
apktool b SystemUI SystemUI-new.apk
After it's done, probably will take around 5-10 minutes. You'll find SystemUI-new.apk in your apktool folder. Open both SystemUI.apk and SystemUI-new.apk with 7-zip. Delete AndroidManifest.xml from SystemUI-new.apk and copy AndroidManifest.xml and META-INF from SystemUI.apk to SystemUI-new.apk
That's it. Close the zip files.
If you have adb or android-sdk push SystemUI-new.apk to your phone using:
Code:
adb remount
adb push SystemUI-new.apk /system/app/SystemUI.apk
adb reboot
If you don't have adb, just copy over SystemUI-new.apk to your phone. Rename it to SystemUI.apk and copy to system/app with root explorer. Reboot.
There you have transparent statusbar now! ​
2. android.policy.jar
Decompile android.policy.jar with:
Code:
apktool d android.policy.jar
You will find android.policy.jar.out, open it and use Cristiano Matos guide to mod the files: http://forum.xda-developers.com/showthread.php?t=2018633
After that use:
Code:
apktool b android.policy.jar.out
Open the android.policy.jar.out folder, you will find a dist folder created and inside that is your modified android.policy.jar.
You can use adb again by:
Code:
adb push android.policy.jar /system/framework
or the normal root explorer method. ​
3. framework-res.apk
Here i'll show you small mods.
Decompile it using
Code:
apktool d framework-res.apk
Navigate to res/values/bools.xml. ​Here you can add these. Thanks to DSA for this! :
4 Way Rotation:
Code:
Code:
<bool name="config_allowAllRotations">false</bool>
Change to:
Code:
Code:
<bool name="config_allowAllRotations">true</bool>
Lock Screen Rotation:
Code:
Code:
<bool name="config_enableLockScreenRotation">false</bool>
Change to:
Code:
Code:
<bool name="config_enableLockScreenRotation">true</bool>
and
Code:
Code:
<bool name="lockscreen_isPortrait">true</bool>
change to
Code:
Code:
<bool name="lockscreen_isPortrait">false</bool>
Disable Keyboard Switch In StatusBar When Typing
Code:
Code:
<bool name="show_ongoing_ime_switcher">true</bool>
Change to:
Code:
Code:
<bool name="show_ongoing_ime_switcher">false</bool>
Unplugging From USB doesn't Turn Screen On
Code:
Code:
<bool name="config_unplugTurnsOnScreen">true</bool>
Change to:
Code:
Code:
<bool name="config_unplugTurnsOnScreen">false</bool>[/indent]
Now to change wallpaper. Change the default_wallpaper.jpg in drawable-xhdpi and to change lockscreen wallpaper change keyguard_default_wallpaper.jpg.
Now recompile using:
Code:
apktool b framework-res framework-new.apk
Delete AndroidManifest.xml from framework-new. Copy AndroidManifest.xml and META-INF from framework-res.apk to framework-new.apk
To test use adb:
Code:
adb push framework-new.apk /system/framework/framework-res.apk
Or rename to framework-res.apk and copy to system/framework using root explorer. Reboot.​
Once you've added everything, your modified apks. Ui_print mods, A custom kernel (just replace boot.img) it's time to compile. Now this is really easy. Just highlight all the folders/files like system, meta-inf and boot.img. Right click. Hover over 7-zip and click Add to Rom.zip. Wait for it to be done, and copy Rom.zip to your sd card and flash. Voila! You've made your rom!!​
You can get more mods to add from here: http://forum.xda-developers.com/showpost.php?p=26583654&postcount=4

Huh?
Get me a screenshot of your meta-inf/com/google/android directory.
What exactly did you modify? It should work if you left the meta-inf untouched.

WORK BEGINS
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
THINGS NEEDED​
(INSTALL BELOW THINGS AS PER YOUR OS BIT VERSION,IF YOU HAVE 32 BIT OS THEN INSTALL 32 BIT STUFFS AND IF YOU HAVE 64 BIT OS THEN CHOOSE 64 BIT STUFFS.
WIndows Running PC or Laptop.
JAVA - Download
Cygwin - Download
7zip Compressor-Download
Notepad++ -Download
Android Kitchen- Download
Time(as per you how much take to understand)
Your Base Rom(stock Rom,in any format-CWM flashable or SP_tools Flashable,Prefer to have Both)
CWM Recovery
SD card & Card Reader.(some phones do not have SD slot so no worry for them,i have alternative way)
APKTOOL- DOWNLOAD
SP_Flash Tools to Unbrick In case Device Get Bricked- Download
SETTING UP IMPORTANT THINGS FIRST​
JAVA
Download Java From Above link as per your OS type.
Install it by running its setup like normal softwares.
CYGWIN
Download Cygwin From Above link.
Extract the Zip
By default it will be installed at c:\cygwin .i also recommend to install at default location.
Run Setup and Select "Install from Local Directory"
Then is will ask for packages location.Verify it.
Hit next-next and finish at the end.
Now you see a Cygwin folder under "C" drive and a shortcut Icon at desktop.
*For some 64 BIT users this method might not work,they can download setup from here-Download & install it from internet instead from local packages and select all packages during installation.
7ZiP
Download 7Zip From Above link as per your OS type.
Install it by running its setup like normal softwares.
Notepad++
Download Notepad++ From Above link as per your OS type.
Install it by running its setup like normal softwares.
dsixda's Android Kitchen
Download dsixda's Android Kitchen From Above link.
Extract it and then it will be like this- Android-Kitchen-0.224\Android-Kitchen-0.224\orgianal_update,tools etc....
Now open Android-Kitchen-0.224 folder and you will again find Android-Kitchen-0.224 folder,then rename it to only " kitchen " (small letters).
Now directory will look like this- Android-Kitchen-0.224\kitchen\orgianal_update,tools etc....
Now copy that kitchen folder which we renamed and paste to c:\cygwin\home"your_username""paste here"
Now your cygwin directory will look like this- C:\cygwin\home\your_username\kitchen\orignal_update,tools,etc.....
To check Kitchen is working,open cygwin from desktop and type - "cd kitchen" and hit enter(small letters).
If no error shown then you have sucessfully installed it or if error like- bash:cd :kitchen:No such file or dirctory hen you should check above steps again.
>>OPENING KITCHEN- open cygwin,type "cd kitchen" hit enter,now type " ./menu " and hit enter.Now kitchen will load.
PORTING CWM RECOVERY(PORT IF YOUR DEVICE DO NOT HAVE IT)- ROOT REQUIRE
Download and install ADB drivers on PC first.DOWNLOAD
Get MTK Droid tools From Here and Extract-HERE
Now go to developers option and enable USB debugging.If you cant find Developers option then go to settings/about Phone and press 7 times on BUILD NUMBER then you will see Developers option under settings.
Open MTK Droid tools on pc and then plug your device(turned on) via usb cable.Now the tool will recognise your device and connect to it(if asked for root permission on device then grant).
If the colour indicator in the bottom left corner is green in MTK Droid Tools,then you already have root shell,and can go on to the next step, if it is yellow, click on the root button at the bottom, and wait for the progress bar, if the indicator stays yellow, or you get an error message, this probably means you do not have Busybox installed, you can install it from the Google play store. When the indicator turns to green you have root shell which is necessary for this operation.
Now click on 'root,backup,recovery' and then select 'to use boot from phone'
Now click on 'recovery and boot'
Then you will see a dialogue box will appear asking if you want to 'make cwm recovery automatically' click yes.
The tool will then create the recovery and then another dialogue box will appear asking to 'install created recovery to phone', click yes.
Now you reboot into recovery mode and check that it is working fine or not.
You can find generated cwm recovery under MTK Droid Tools location.
If you want to revert to stock recovery then take recovery.img from your stock rom(sp_tools) and paste into sd card.And then install mobileuncletools from playstore and click on update recovery and select your stock recovery from SD.Same method for installing CWM recovery.
WHICH ROMS YOU CAN PORT​
Port rom should be of same android version as your stock rom.Like if your stock rom is 4.2 then you should only try with 4.2.In some cased you can port higher versions like kikat too,it will require Custom kernel but we are skipping that.
The device from you porting should have same chipset,like if your device is MT6589 then you shoul only try with MT6589 chip-sets.You can port from MT6589T to MT6589 or MT659M but you cannot port from MT6592.
Choose the port rom from most close specification device,like screen size,screen resolution,dual-sim,etc....higher resolution to lower resolution resolution or lower to higher can be ported but not all boots up.
Some Sites To get Port Rom:-
anzhuodiy.com
romzj.com
dashi.com
shendu.com
needrom.com

Porting begins
MAKING PORTING ENVIRONMENT​
Registering Your Device To Kitchen:-This step will help to write updater script automatically.
Open kitchen and select option 0(advance options) and then select option 12(tools for unpack and repack boot.img etc.) and press "a"(Extract kernel+ramdisk from boot.img,recovery.img etc.) and hit enter.
Now a folder will be created Under kitcehn directory named like this- bootimg_040714_132352
Now copy your CWM recovery.img for your device to this folder and check that the name must be - recovery.img if not then rename it. and hit enter in kitchen terminal.It will extract your recovery in that folder.
Open up boot.img-ramdisk folder, and look for /system/etc/recovery.fstab or /etc/recovery.fstab or similar FSTAB file location. Open this file by notepad++ to find the mount points.
Download below file and paste it to C:\cygwin\home\username\kitchen\tools\edify_defs .Now rename it to your device code name.Mine is A110Q so i used this file. You can use as your choice also.
Then open this file and recovery.fstab with notepad++ and compare and replace mount points and save it.Means copy mount points from recovery.fstab and paste/replace into Your device codenamed file.
Now if you done all above steps right then kitchen will make updater script for you.
If you porting for Micromax A110Q then just Download the below File and paste it.No need to edit.Just paste it.
>>>>>>Micromax A110Q file - http://d-h.st/Qa5
>>>>>>IF you have any confusion or you are unable to create this file then PM me your recovery.fstab file and i will make it.
GET BOTH ROMS- STOCK AND PORT
STOCK-Your stock rom which was provided by device manufacturer.
PORT- The Rom you selected to port after comparing your device to port device.
GETTING STOCK ROM SYSTEM FOLDER
IF your Stock ROM is in already in form of CWM flashable zip then create a Stock Folder in any drive of Computer and extract it for further Use.
Basic Strurture od CWM FLASHABLE ZIPs
META-INF
SYSTEM
DATA
boot.img
IF YOUR ROM IS SP_TOOLS FLASHABLE THEN DO THESE TO EXTRACT SYSTEM FOLDER FROM IT:-
Basically IN SP_TOOLS flashable zips the folder structure is-
DATABASE
boot.img
cache.img
EBR1
EBR2
IK.bin
logo.bin
MBR
MT65xx_Android_scatter_emmc.txt
Preloaded_xxxxxx.bin
recovery.img
secro.img
system.mg
userdata.img
[STEPS]
Extract system.img from stock rom zip to C;\cygwin\home\username\kitchen\original_update
*You should add kitchen folder to favorites panel in my computer as you will be using this folder very frequent.
Now open cygwin,type "cd kitchen" hit enter,now press- " ./menu " then android kitchen will load with lots of functions numbering from 1 to ...
Press 1 to setup working folder now again hit Enter.Now it will ask you to choose an option to select working folder.Select system.img one folder by pressing its value and hitting enter.
Now it will ask about changing working folder name,leave it as default and hit enter.So kitchen will now start copying rom to working folder.
After Copying files it will auto prompt and open Ext2Explore application.In some cases it will show that error message that "unable to read disk,please make sure you are running appliacation with administrative rights."But don't worry,click ok.
Now after Ext2Explore opened,click on "FILE" on upper left corner and click on "OPEN IMAGE".Now browse to kitchen directory and go through newly created working folder and you will find "ext4_system.img" under system folder.Select it.
Right click on file selected in Ext2Explore and Click on SAVE,now browse to same folder where "ext4_system.img" was.Means newly created working folder/system under kitchen directory.
Then it will extract "ext4_system.img" to same folder.After finishing extraction close the Ext2Explore application.Now hit Enter in kitchen,again it will say "warning,no boot.img found" .Do not worry,HIT ENTER and go with default.
It will ask to view Rom info,you can skit this.
So finally you got system folder under working folder.So copy that system folder to any drive and rename it to Stock rom folder for further use.
[TIP:-]
>>IF your Rom is odexed then you should deodexed it before copying to any other drive for further use.<<
HOW TO CHECK THE ROM IS ODEXED:-
GO TO SYSTEM/APP and SYSTEM/FRAMEWORK folder and see that for every file there is clone file ending with .odex .If there is then your rom is odexed.
WHAT IS DEMAERIT OF ODEXED ROM FOR DEVELOPERS-
You will not able to theme and modify your rom if system and framework is odexed so better deodex the rom.Deodexing will combine file and its clone .odex to one unit.
DEODEXING:-
AFTER SETTING UP WORKING FOLDER AND DOING ALL ABOVE STEPS,now hit 0 in kithcen and select 11 option and hit enter.
IT will show number of odex files in your Rom.Now Select "b" option to deodexing all files,it will take some time.
After done,it will show that "0" files left odexed in Rom,now exit kitchen and Now you should copy your system folder to any drive for furter use.
GETTING STOCK ROM BOOT.IMG EXTRACTED
[STEPS]
Now open Kitchen and select 0(advance options) and Hit enter,now select option 12(tools for unpack and repack boot.img etc.)
Under 12th option,press "a"(Extract kernel+ramdisk from boot.img,recovery.img etc.) and hit Enter
Now a folder will be created Under kitcehn directory named like this- bootimg_040714_132352 Now copy your boot.img and paste into this folder.
Now switch to Kitchen Terminal and press Enter.Then it will do some process and extract your boot.img,Now copy that folder and save it to any drive and Rename it to stock boot for further use.
NOW DOWNLOAD PORT ROM YOU CHOOSED TO PORT AND MOVE TO NEXT STEP BELOW.​

PORTING
PORTING​
>>>>Follow STEP I if you have port rom flashable via cwm.To check that your rom is flashable vai cwm see above post for structure.Those who having SP Tools flashable port rom follow StepII directly.<<<<
First we will port and check that rom boots or not by simple way,then if it boots then we will modify it and tweak it by using kithcen.Or you can skip this step I and directly follow step II but you have to do almost all things from step I in Step II except modifying updater script.If you do these things in step I then no need to do in Step II.
STEP I​
[*]Make a folder and name it as you want and copy and paste your port rom zip in it,means make a clone file of it and we will be working with clone zip,always keep in mind.I said to copy paste as if your rom did not boot up then you have a backup of clean port rom.
[*]Now create a folder under original update of kitchen- " WORKING_XXXX "
[*]Then open zip using 7zip(make 7zip is as default app) and drag drop boot.img to " WORKING_XXXX " folder.Now Open kitchen and Press 1 to setup working Folder.And go with default in all steps forward.(keep 7zip opened,you will need to drag back boot.img in it)
[*]After working folder setuped.Now press 0 for advance option and hit enter.Now press 12 and hit enter.Now you press "w" to extract boot.img from working folder.
[*]After sucessful extraction you will find a folder under kitchen named BOOT EXTRACTED.
[*]Now you have to copy zImage from stock boot extracted folder(which was created by you in second post last step) to this BOOT EXTRACTED folder and replace it.
[*]Then switch to kitchen and press "b" to build boot.img from BOOT EXTRACTED folder then after repacking boot.img finish,you have to drag and drop only boot.img(kitchen/working folder)(not meta-inf) to port rom zip.
[*]Now Open System Folder In port Zip and drag drop build.prop file out of it to anywhere you wish.
[*]Now edit it with Notepad++.
[*]Add this line if you are porting from a higher resolution device- ro.sf.lcd.density=220 .Change its value after rom boots as to your display resolution.If after rom boots up and everything looking large then reduce the value and if looking small then increase it.
[*]You can Edit These Values as desired:-
Code:
ro.build.id=
ro.build.display.id=
ro.custom.build.version=
ro.build.version.release=This is Andriod version That Displays in Settings
ro.product.model=
ro.product.brand=
ro.product.name=
ro.product.device=
ro.product.manufacturer=
ro.build.bluetooth.name=
[*]EDIT BELOW LINES TO SET YOUR TIMEZONE AND AREA REGION.You can find your default details in your stock rom's build.prop which you extracted earlier.
Code:
ro.product.locale.language=(en for English,ru for Russian and other similar codes for other language)
ro.product.locale.region=(us for usa, IN for india etc.)
persist.sys.timezone=( Asia/kolkata for india,Asia/... different for different regions)
[*]Now after editing done drag build.prop to port zip.
[*]Now keep opened port zip one side and open stock rom system folder which we extracted in post 2.
[*]Open System/etc/firmware in both zip and stock folder.Now drag modem.img from stock folder to zip and drop it.
[*]Now head to lib folder in both.Here you have to drag and drop libcamercustom.so file to port zip.
[*]Go to system/lib/modules now,here drag and drop mtk_stp_wmt.ko file to port zip.If rom did not boots forward then you should drag and drop whole modules folder under system/lib of port zip.
[*]Go to usr/keylayout in both and drag drop Generic.kl file from stock to port zip.
[*]Lastly drag and drop a launcher like nova,apex or any to system/app/ of port zip in case port launcher did not worked.
[*]IF you rom did not booted by applying all above steps then replace these folder/files from stock to port:-
1)system/etc/firmware
2)system/lib/hw
3)system/lib/modules
4)system/vendor
[*]If your cwm port rom zip have these files then delete those.
---uboot.bin
---preloader
---logo.bin(you can keep it but you need your stock logo.bin which is available in sptool flahable roms.I will also tell you how to create own logo.bin and bootanimation in below post.)
[*]Your zip should look like this-
--Meta-inf
--system
--boot.img
--data (in some roms)
[*]After deleting the extra files you need to modify the updater script which can be found under,Meta-inf/com/google/android/updater-script...we are modifying by own only this time as we have to check only.During building rom from kitchen,it will be automatically created
as we registered our device.If we do not register our device in kitchen then during making roms from kithcen our current updater script will converted to update script which will be again converted to updater script and that will cause installation aborted error.
[*]Now drag and drop updater script from zip to anywhere and open it with notepad++,now find lines below-
Code:
format("ext4", "EMMC", "/dev/block/[COLOR="DarkOrange"]mmcblk0p7[/COLOR]", "0");
format("ext4", "EMMC", "/dev/block/[COLOR="DarkOrange"]mmcblk0p5[/COLOR]", "0");
mount("ext4", "EMMC", "/dev/block/[COLOR="Red"]mmcblk0p7[/COLOR]", "/data");
mount("ext4", "EMMC", "/dev/block/[COLOR="Red"]mmcblk0p5[/COLOR]", "/system");
[*]Here you have to deal with text in red.Your updater script may be different so use your brain and understand what i am saying forward.Text in red is mount point.In above mmcblk0p7 is mount point of data folder and mmcblk0p5 is mount point of system folder.So you need to replace mount points of updater script with your device mount points.You must found mount points of your device during registering device to kitchen.So open recovery.fstab or that kitchen/tool/edify_defs/your file with notepad++ and copy replace mount points from your device file to updater-script of port zip.If you find those lines any more places in updater script then also replace there.Here you only need some mind to use.For example if you edited and replaced red text then you must also replace orange text as they are also same.
[*]Remove the lines of the files which you removed in zip if there,like uboot.bin,logo.bin,preloader etc...they will look like below codes,you only need to find the line matching to the file you removed and deleat that.
Code:
package_extract_file("uboot.bin", "/dev/uboot");
or
assert(package_extract_file("uboot.img", "/tmp/uboot.img"),
write_raw_image("/tmp/uboot.img", "uboot"),
delete("/tmp/uboot.img"));
or
assert(package_extract_file("preloader.img", "/tmp/preloader.img"),
write_raw_image("/tmp/preloader.img", "preloader"),
delete("/tmp/preloader.img"));
[*]And replace this line
Code:
assert(package_extract_file("boot.img", "/tmp/boot.img"),
write_raw_image("/tmp/boot.img", "bootimg"),
delete("/tmp/boot.img"));
From this if any error occurs during installtion like boot.img assert failed.
Code:
package_extract_file("boot.img", "/dev/boot");
[*]Drag back the updater-script to zip from where it was taken from.
What we have done above is that we drag and drop some stock files from stock rom to port zip without extrating it.​
Now you are good to flash your ported rom.Make CWM backup if you want to go back to previous rom or rom did not booted.After that wipe data factory reset,wipe cache partition,wipe dalvic cahce under advance option and then format system under mount and storage OF CWM RECOVEY then install zip from sd card and install your zip.I said SD card in first post if your rom did not booted and you understood your mistake and modified your port rom zip then you can do that directly by transferring zip to sd and flash instead of installing or restoring another rom.But for the users with not sd card must save their CWM backup or a working cwm flahable Rom zip otherwise they will have to reflash the rom by SP tools if rom didnot booted.
STEP II​
NOTES BEFORE BEGINNING STEP II :-
If you ported your ROM using STEP I and booted then for modifying use this STEP II.
If you tried porting rom using STEP I but it is showing installation aboted then follow this STEP II directly.
IF you have SP Flash tools format port rom and you extracted system folder and boot.img from your stock rom using my method then Follow STEP II directly.
STEP II contains some steps from STEP I,so if you already did those steps in STEP I and using same zip here then you can skip steps here.If you get confused then again do all steps.
STEP(A)- ADDING A WORKING FOLDER IN KITCHEN
FOR CWM ROM:-
Create a folder " WORKING_XXXX " under kitchen/original _update if you haven't.If you having it then check that it is empty.
Now open your port zip (or zip you ported through STEP I and was booted) and extract its System and boot.img to "WORKING_XXXX " folder.
Open kitchen and press "1" to setup a working folder.
Press Enter and select "WORKING_XXXX " folder by it assigned digit and hitting Enter
Now it will ask for name,you may change it or leave it,it does not matter.Skip it by pressing Enter.
It will start copying files to a working folder,wait sometime.
After it will ask to view Rom info,then press Y and see its info as your wish.
Now you have a working folder setup-ed.
FOR SP TOOLS ROM:-
Extract system.img & boot.img from port rom zip to C;\cygwin\home\username\kitchen\original_update
Run Kitchen and press "1" to setup working folder and hit enter.
Now again hit Enter,this time it will ask you to choose an option to select working folder,Select system.img&boot.img one folder by pressing its value and hitting enter.
Now it will ask about changing working folder name,leave it as default and hit enter.So kitchen will now start copying rom to working folder.
After Copying files it will auto prompt and open Ext2Explore application.In some cases it will show that error message that "unable to read disk,please make sure you are running appliacation with administrative rights."But don't worry,click ok.
Now after Ext2Explore opened,click on "FILE" on upper left corner and click on "OPEN IMAGE".Now browse to kitchen directory and go through newly created working folder and you will find "ext4_system.img" under system folder.Select it.
Right click on file selected in Ext2Explore and Click on SAVE,now browse to same folder where "ext4_system.img" was.Means newly created working folder/system under kitchen directory.
Then it will extract "ext4_system.img" to same folder.After finishing extraction close the Ext2Explore application.Now hit Enter in kitchen and go with default then Press y to view ROM info as per your wish.
Now you have a working folder setup-ed.
STEP(B)-Porting Rom
PATCHING BOOT.IMG:-
After successful creation of working folder you will find a new folder created named like-"WORKING_041214_135729".
Open kitchen then Press 0 for advance option and hit enter.Now press 12 and hit enter.Now you press "w" to extract boot.img from working folder.
After sucessful extraction you will find a folder under kitchen named BOOT EXTRACTED.
Now you have to copy zImage from stock boot extracted folder(which was created by you in second post last step) to this BOOT EXTRACTED folder and replace it.
Now switch to kitchen and press "b" to build boot.img from BOOT EXTRACTED folder then after repacking boot.img finish press x to exit and back to main menu.
Editing Build Prop:-
you will find build.prop under kitchen/your_working_folder/system/
Edit build.prop with notepad++
You can Edit These Values as desired:-
Code:
ro.build.id=
ro.build.display.id=
ro.custom.build.version=
ro.build.version.release=This is Andriod version That Displays in Settings
ro.product.model=
ro.product.brand=
ro.product.name=
ro.product.device=[B][U][COLOR="Red"]NAME OF FILE WHICH YOU USED TO REGISTER YOUR DEVICE TO KITCHEN[/COLOR][/U][/B]
ro.product.manufacturer=
ro.build.bluetooth.name=
EDIT BELOW LINES TO SET YOUR TIMEZONE AND AREA REGION.You can find your default details in your stock rom's build.prop which you extracted earlier.
Code:
ro.product.locale.language=(en for English,ru for Russian and other similar codes for other language)
ro.product.locale.region=(us for usa, IN for india etc.)
persist.sys.timezone=( Asia/kolkata for india,Asia/... different for different regions)
Add this line if you are porting from higher resolution deice or lower resolution device.If from higher to lower then put lower values and if lower to higher then put higher values.
Code:
ro.sf.lcd_density=xxx
Now after editing done save it and exit.
Patching Rom With Some STOCK Rom Files:-
Copy modem.img from stock Rom- System/etc/firmware to kitchen/working_folder/system/etc/firmware and replace it.
Copy libcamercustom.so file from stock Rom- System/lib to kitchen/working_folder/system/lib and replace it.
Copy mtk_stp_wmt.ko file from stock Rom- System/lib/modules to kitchen/working_folder/system/lib/modules and replace it.If ROM not booted then replace whole modules.
Copy Generic.kl file from stock Rom- System/usr/keylayout to kitchen/working_folder/system/usr/keylayout and replace it.
Download any launcher apk from net link nova,apex etc and paste into kitchen/working_folder/system/app/
If after Building rom from next step,your rom did not booted then replace these files from stock to port then build rom.
1)system/etc/firmware
2)system/lib/hw

Building Rom
After all above steps done,now switch to kitchen and press 99 to build ROM.
But before pressing 99 check that you put name of file by which you registered your device to kitchen in build.prop/ro.product.device="".If you registered with name x then put like this-ro.product.device="x"
If you have not done above step then you will get installation aborted error during installation.If you are confused to register device send me required fies as asked by me in above post.
After all checked now press 99
Select Build Option 1 then hit Enter
Now it will ask to zip-lang the apk,do as your wish.
After that step it will convert Updater Script and ask two option,Proceed or cancel,then Proceed by pressing "y".
It will then start making update.zip.Wait some time.
Next it will ask to sign the zip or not?You should go with default by signing update zip by hitting Enter or Pressing "y" then pressing enter.It will take some time.
After that if you want to change your ROM name then put desired name by pressing y or leave as it is by hitting Enter or 'N' then enter.
Collect you rom.zip from Output_zip folder created under kitchen directory.
Flash it and check it.
If you find some bugs then see post below to solve bugs or if you are not able to find bug solution below then post it.I will tell you how to solve it if i know.
I have ported 10+ Roms using this method,this should work for you too.Hopes that your ROM will boot.Good Luck.​

SOLVING BUGS​
BUG SOLVING USES HIT AND TRIAL METHOD.I mentioned one or more ways to solve,you try one by one and see which works for you.
FM NOT WORKING:-
COPY THESE FILES FROM STOCK TO PORT:-
\system\lib\libaudio.a2dp.default.so
\system\lib\libaudio.primary.default.so
\system\lib\libaudiocompensationfilter.so
\system\lib\libaudiocustparam.so
\system\lib\libaudioeffect_jni.so

\system\lib\libfmmt6616.so
\system\lib\libfmmt6620.so
\system\lib\libfmmt6626.so
\system\lib\libfmmt6628.so
OR try this
system/etc/firmware/mt6620_patch_e3_hdr.bin
system/etc/firmware/mt6620_patch_e6_hdr.bin-> If yours is MT6628, you'll need to patch all mt6628_fm_*_*.bin too
system/etc/firmware/WMT.CFG-> This is the antenna cfg, without this, FMradio cannot receive clearly
system/lib/modules/mtk_fm_drv.ko
system/lib/libfmcust.so
For WiFi Bluethooth:-
system/lib/modules/mtk_wmt_wifi.ko -> After patching, both works & can be individually switch on/ off
system/lib/libbluetooth_mtk.so
system/lib/libbluetoothem_mtk.so -> MTK Engineering will show MT6628 if not patch...
system/etc/firmware -> if yours is MT6628, you'll need to patch all WIFI_RAM_CODE_* too
For GPS:-
->>>> system/xbin/libmnlp
or, If you porting From MT6628 to MT6620, some apps at system/vendor/operator/ is blocking GPS so just delete all apps & use MTK Engineering mode to confirmed it...
Edit in build.prop
fmradio.driver.chip=1 -> if yours is MT6628 then change it to 3
mediatek.wlan.chip=MT6620 -> if yours is MT6628 then change last digit to 8
mediatek.wlan.module.postfix=_mt6620 -> if yours is MT6628 then change last digit to 8
For Camera:-
->Unpack boot.img again and go to BOOT-EXTRACTED/boot.img-ramdisk/init.project.rc and edit with notepad++,also open stock bootextracted/ramdisk/init.project.rc.Now find camera permissions and replace whole camera line with stock camera lines.
->then open init.rc of both port and stock and find camera lines and copy/replace camera lines from stock to port.
->Now repack boot.img
OR
copy these from stock to port
system\lib\hw\camera.default.so --- (if you have two files like camera.goldfish.so delete this the one with the goldfish)
\system\lib\libcamera_client.so
\system\lib\libcameracustom.so
\system\lib\libcameraprofile.so
\system\lib\libcameraservice.so

copy from system/lib of stock to port.
- libmhal.so
- libmhalcontent.so
- libmhaldrv.so
- libmhalmdp.so
- libmhalpipe.so
- libmhalscenario.so
- libmhalutility.so
or
Put libcamdrv.so of rom only or campare the file of size of your porting rom file and the base rom then whose size is same leave it and whose size is greater in ur stock rom jst add and replace that file only.
or
lib3a.so

(Skip if any missing)
or
Replace camera.apk in sysyem/app
And do a ctrl+f search in system/lib for anything called 'camera', 'camrecorder', or just 'cam' and replace those.
Storage mount Problem Fix:-
copy paste sytem/etc/vold.fstab from stock to port
USB NOT MOUNTING IN PC FIX:-
copy init.usb.rc from stock boot.img extracted to port and repack.
Audio Problem Fix:-
copy paste sytem/lib/all audio lib file from stock to port.(search by ctrl+f)

DATE AND TIME ERROR FIX:-
check build prop region and compare and replace from stock build prop.
or
Use gravity box date and time fix
Minimum Brightness:-
ro.init.screen_brightness=110 in build prop
If App Force Closing:-
Use Updated App or if only rooted apps are getting Force close then Check Root
If nothing helped then removed that apk from system folder.
If a weird image Showing Between Boot logo and boot animation:-
Use stock rom's system/media/images/boot_logo in port.

USE PORTED APPS IN YOUR ROM
HERE IS LINK OF HUGE COLLECTION OF PORTED APPS:-CLICK
How to Implemant Ported Apps?
->Download it and open its zip.
->Now open system folder in zip and drag and drop all files to port rom means copy all system folder contents only to port system folder.
More things will be added soon.

THEMING​
I will discuss very short on Theming,rest search on Google.
[START]
SETTING UP APKTOOL:-
->>If you have installed apktool and java then you can start.
->>Now go to the extracted apktool folder and hold "SHIFT" keyboard button and then right click mouse.
->>Here select-Open command window Here" option.
->>For Theming you need to decompile the apk which you want to theme,so grab those apks first and put into apktool folder.
-->>Also take framework-res.apk and medaitek-res.apk and put these also in apktool folder.
->>For decompiling system folder apk,you need to install framework-res.apk and medaitek-res.apk first.So in command window input-
Code:
apktool if framework-res.apk
apktool if mediatek-res.apk
->>hit enter one after one.So you will get message that apk installed to....for both apks.
->>Always write words carefully in command terminal,write same words as apks in apktool folder.
NOW YOU CAN DECOMPILE SYSTEM APKS OF THE ROM WHOSE FRAMEWORK YOU HAVE INSTALLED.IF YOU DONE WITH THAT ROM AND WANT TO MODIFY NEXT ROM APKS THEN
GO TO C:\users\yourusername\apktool and delete all present apks.
Lets start Decompiling:-
->>Open command terminal under apktool,if you already opened then good.
Lets assume that you are decompiling launcher.apk then,
->>Type this below command to decompile apk.You need to replace only apk name....
Code:
apktool d launcher.apk
->>and hit enter.It will decompile in same apktool folder.
->>Now open it and modify it as you wish.
->>For editing its images and theme and look,go to drawable-hdpi folder replace pngs with same resolution pics or edit with photoshop or gimp etc.
->>You can do major modification in thems with systemUI.apk
->>And for rest take help from google.I will update this and add more stuffs when i get time.
->>Now after all modifications done,now lets compile apk.Use command below and replace apk name....
Code:
apktool b launcher.apk
->>Hit enter.Now you have to drag and drop meta-inf and AndroidManifest.xml of launcher.apk which was placed under apktool directory for decompiling(use 7 zip to open apk and drag files from it) to apktool directory/launcher/build/apk/ and replace when prompt.
->>Now again repeat this command in command bar-
Code:
apktool b launcher.apk
->>hit enter,Now this time you can collect you compiled apk from- apktool directory/launcher/dist/"launcher.apk"
->>I know you may get confused by all these steps so watch an awesome video by nero young to clear your confusions-VIDEO

MAKING PATCHES ZIP​
IT WILL BE VERY EASY FOR YOU TO MAKE PATCHES ZIP IF YOU DOWNLOAD THESE BELOW 4 FILES :-
1) ONLY BOOT.IMG PATCH ZIP
2) ONLY SYSTEM FOLDER PATCH ZIP
3) SYSTEM FOLDER + BOOT.IMG PATCH ZIP
4) KERNEL ZIP & KEREL REVERT ZIP.
Download above Zips.
First zip is for extracting only boot.img patch .
Second zip will patch system folder's all folder.
Third Zip will allow you to patch both boot.img and system folder contents of your rom.
Fourth one will allow you to flash any custom kernel if available for your device.
How to use all above patches.zip?
->For first one open zip using 7zip and drag the boot.img you want to patch to it then flash it with cwm
->For second one,if you want to add an apk or any other lib files or replce lib file or any other system folder files to your rom then drag and drop that file to second zip with correct folder path.
->Third one will allow first and second to flash at once.
->Fourth zip is for custom kernel,Custom kernel contains two part,boot.img and another system/lib/modules/lots of file.For custom kernel flashing or reverting with stock kernel,you need to drag and drop boot.img and system/lib/modules/ to fouth zip and flash via cwm.
IF YOU WANT TO ADD UBOOT.BIN TO ROM OR FLASH UBOOT.BIN THEN USE BELOW LINE IN UPDATER SCRIPT:-
package_extract_file("uboot.bin", "/dev/uboot");
Click to expand...
Click to collapse

ADDING OTA UPDATE​
You will need to download its apk first- OTA_UPDATER_DWONLAOD
You will also require all 4 patch zips from above post.
STEPS TO ADD OTA UPDATE :-
Put OTAUpdater-1.0.5.apk in system/app folder.
Edit build prop by notepad++ and add these three lines:-
Code:
otaupdater.otaid=<ROM ID any you can pick>
otaupdater.otatime=<Date/time of this build in yyyymmdd-hhmm format>
otaupdater.otaver=<The human-readable version number/name>
EXAMPLE FROM MY ROM:-
Code:
otaupdater.otaid=xos
otaupdater.otatime=20130930-1553
otaupdater.otaver=1.0
Now you are good to receive and send OTA update to your Rom....but first you have to setup account online.
Registering Device Online
Go to https://www.otaupdatecenter.pro/ and Register there.
After successful registration,click on +Add Rom.A form will be opened then.Fill it.
1)Enter Rom name same as you written in build prop display id.
2)Enter ROM OTA ID (as in build.prop)
3)Enter ROM version (as in build.prop)
4)Enter OTA date/time here (yyyymmdd-hhmm, as in build.prop).
5)Enter download url.(put any URL right now,we are just adding rom first)
6)Enter MD5 file-hash.(put any file md5 check sum.we will edit it when we provide update)
7)Put any Change log...write anything
8)On last column put the name of your device same as in build prop "ro.product.device= ".In my case i use a110q and here is my code in build prop:-
Code:
ro.product.device=a110q
Lastly do not tick on check box as it will make OTA private.
Now your device is registered.
PROVIDING OTA UPDATE:-
Create update using any of my 4 files which you need to update.Lets assume you want to update an apk or add an apk,so you will use my only system folder patch zip.
Now open my provide zip using 7zip and drag and drop your apk with its path.As i provided patch with only system folder and no path forward.So open system folder and right click and create folder,name it "app" and then open app and drag apk in it.
If you were updating bootanimation then you should create media folder under system folder of my zip.
Now after making patches done.Download the Sign-em! from HERE and extract it anywhere.
You will get input,output and some more files....put your zip in input and run "sign-em.bat",it will sign your update zip and also give you its md5checksum.Signing your update is necessary.
After signing zip upload it to drop-box (suggested and tested) and after upload finished,click on download button and copy its url which is generated after that.Means copy url which is prompt in download manager if you using.If you do not use this url then OTA will not work.
Again open https://www.otaupdatecenter.pro/ and go to rom list and click on update rom.
This time put download URL which was generated after clicking download button on dropbox in URL box and also put its md5 checsum which was generated in output folder text file of sign-em!!
And change version also,put 2.0 in version if earlier 1.0,you can also put 1.1 or 1.2 any you want but change it.
And lastly put new date and time as per its format and give your update description if you want.
Check all things then click Update.All done you are good to get update.
Your mobile should have data connection enabled all time during this process.
if any confusion ask me or see faq on https://www.otaupdatecenter.pro/
WIP

ADDING CUSTOM KERNEL​
CUSTOM KERNEL ZIP STRUCTURE:-
->>Meta-inf
->>system/lib/modules
->>boot.img
For Adding it to your rom extract your kernel zip or drag and drop system/lib/modules/all files to port rom and replace all.
Then switch to kitchen and press "0" for advance option and then 12 for extracting boot.img.Here press "a" for extracting boot.img from any folder.Hit enter,you will see a folder created named like "bootimg_041114_230352" and put your custom kernel boot.img in it.
Now press Enter then kitchen will extract it in same folder.
Then back to kitchen 12 th menu of extraction of boot.img,here press "w" to extract boot.img from working folder,so it will extract boot.img from port rom(which is present in working folder) to BOOT-EXTRACTED folder under Kitchen.
Now copy zImage from previous extracted folder "bootimg_041114_230352" to BOOT-EXTRACTED folder and replace it.
Press b in kitchen to repack boot.img.All done.
What we have done above- We used zImage(from boot.img) of custom kernel in port rom boot.img and used all system/lib/modules folder from Custom kernel zip.

ADDING SMALL BUT COOL STUFFS​
ADDING DESIRED TEXT DURING ROM INSTALLATION:-
After Finishing your Rom,drag and drop Meta-inf/com/google/android/"Updater-script" to anywhere in your pc.
Now open it with Notepad++,and use this code to dislpay your texts in installation:-
Code:
ui_print(" ");
Put any alphabet or symbol or digit between (" ") and it will show during Installation.
For generating cool Ui prints you can search Google about text to ASCII converter websites and put your text and get cool texts for installation window.
After all modifications done,drag and drop back updater script to zip.
For Example:-
Code:
ui_print("========STARTING INSTALLATION===========");
ui_print("========================================");
ui_print(" |\ _,--------._ / | ");
ui_print(" | `.,' `. / | ");
ui_print(" ` ' BEAST ,-' ' ");
ui_print(" \/_ _ ( / ");
ui_print(" (,-.`. ,',-.`. `__,' ");
ui_print(" |/*\ ),-','*\`= ,'.` | ");
ui_print(" `._/) -'.\_,' ) ))| ");
ui_print(" / (_.)\ . -'// ");
ui_print(" ( /\____/\ ) )`'\ ");
ui_print(" \ |V----V|| ' , \ ");
ui_print(" |`- -- -' ,' \ \ _____ ");
ui_print(" ___ | .' \ \ `._,-' `- ");
ui_print(" `.__,`---^---' \ ` -' ");
ui_print(" -.______ \ . / ______,- ");
ui_print(" `. ,' ");
ui_print("=== STOCK BEAST ROM BY DIGYVIJAY KR. ===");
ADDING AROMA INSTALLER:-
Take help from HERE
And here is an HELPFUL VIDEO.
I will explain these stuffs later
ADDING CUSTOM BOOT ANIMATION & SHUT-ANIMATION:-
You Can find bootanimation and shutanimation under system/media folder.If you ported from larger resolution device or smaller resolution device then animation will look weird.so you need to resize it or add own made one.
[*]For adding own or editing previous boot-animation you will need this software-Download thanks to @despotovski01 for this)
[*]Now install it.You will also need to know your mobile resolution for making or resizing boot-animation or shut-animation to your size.
FOR RESIZING BOOT-ANIMATION & Shutanimation:-
[*]Take bootanimation.zip from system/media and extract it to any folder.
[*]Now you will see lots of images in it under its sub folder like part0 part1...
[*]Resize all images to your screen resolution.You can use some softwares to resize them easily.Find on Google.(do not mess with serial number order)
[*]Now make a New folder and make another folder under it named- "part0" and put your all resized pngs to it.(from all folders you have in your bootanimation.zip)
[*]Start Boot Animation Factory and Click on "create a new boot-animation",then choose "folder" and click OK.
[*]Now click choose folder button and browse your created folder in which you put part0 folder.DO not choose part0 folder,choose is outer folder.
[*]Here Click on add loop then select part0 folder in prompt dialog box and click on add.
[*]If you want to repeat animation then tick repeat.Now you should preview it first before saving.you can adujust animation speed by clciking on text above your loop created,and click to edit it and then edit FPS according to need.Here is the example line:-30 is FPS here and rest is reso...

FOR CREATING BOOT-ANIMATION & Shutanimation:-
You will have to use own creativity skill for creating its frames.Some knowledge of Photoshop required.
Design your boot animation frames and manage it serially.
Create a folder with any name and create another sub folder in it named "part0" and put all your designed pngs in it.
Start Boot Animation Factory and Click on "create a new boot-animation",then choose "folder" and click OK.
Now click choose folder button and browse your created folder in which you put part0 folder.DO not choose part0 folder,choose is outer folder.
Here Click on add loop then select part0 folder in prompt dialog box and click on add.
If you want to repeat animation then tick repeat.Now you should preview it first before saving.you can adujust animation speed by clciking on text above your loop created,and click to edit it and then edit FPS according to need.Here is the example line:-30 is FPS here and rest is reso...

Samsung Galaxy S8 Change Navigationbar using ADB Shell

Hi there,
i used the ADB Shell to push the NavBar on the Bottom down for about -35 px but my problem is that the Standard Bar still got a littel chin/space on the top. Look in the Screenshots...
Original NavBar: prntscr.com#k5qjl9 (just add HTTP and replace the # with /)
Modified NavBar: prntscr.com#k5qk0c (just add HTTP and replace the # with /)
(Had to remove the URL bcs im new to this Forum...)
I marked the Space Yellow...
Is there any Command to Overlab the Displaypart over the Bar or to just Cut it?
Best Regards Joker

[GUIDE] How to make GSIs overlay file for your phone

Hello, when you using phh's GSIs, you may found bugs on auto brightness, battery usage data, etc (e.g: Xiaomi, Huawei, etc.). For this, you can make an overlay files for your mobiles.
Requirements:
framework-res.apk on your stock rom. (It may on /system/framework/framework-res.apk)
apktool (to extract framework-res.apk)
git (to clone repo)
Linux (to build overlay files)
Steps:
1. Fork phhusson/vendor_hardware_overlay on GitHub.
2. Clone Repository which you forked, and make a new branch for your works.
3. Copy a device which similar for your device, and rename it to your own device.
4. Edit <Your device>/Android.mk (Just modify the contents of the brackets, same as below)
Code:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_PACKAGE_NAME := treble-overlay-[Manufacturer of your device]-[Name of your device]
LOCAL_MODULE_PATH := $(TARGET_OUT)/overlay
LOCAL_IS_RUNTIME_RESOURCE_OVERLAY := true
LOCAL_PRIVATE_PLATFORM_APIS := true
include $(BUILD_PACKAGE)
5. Edit <Your device>/AndroidManifest.xml
Code:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="me.phh.treble.overlay.[Manufacturer of your device].[Name of your device]"
android:versionCode="1"
android:versionName="1.0">
<overlay android:targetPackage="android"
android:requiredSystemPropertyName="ro.vendor.build.fingerprint"
android:requiredSystemPropertyValue="+[write as similar format]*"
android:priority="[Take next number of last used]"
android:isStatic="true" />
</manifest>
If you don't know how to take androidriority, you can execute this commands to list priority which used already:
Code:
cd [Path of repository]
find -name AndroidManifest.xml |while read manifest;do packagename="$(xmlstarlet sel -t -m '//manifest' -v @package -n $manifest)";priority="$(xmlstarlet sel -t -m '//overlay' -v @android:priority -n $manifest)";echo -e "$priority\t$packagename";done|more
(the single line command split here, just for viewing or making a shell script):
Code:
find -name AndroidManifest.xml |while read manifest;do
packagename="$(xmlstarlet sel -t -m '//manifest' -v @package -n $manifest)";
priority="$(xmlstarlet sel -t -m '//overlay' -v @android:priority -n $manifest)";
echo -e "$priority\t$packagename";
done
It will print a list for you (unsorted), and you just take an unused priority.
You can find device fingerprint on /vendor/build.prop, or execute following commands (on your device or adb shell):
Code:
getprop ro.vendor.build.fingerprint
If you can't find ro.vendor.build.fingerprint, you can find ro.vendor.product.name or ro.product.vendor.device, then change android:requiredSystemPropertyName and android:requiredSystemPropertyValue what you found.
Huawei seems to use ro.hw.oemName to detect phone, and others manufacturer maybe have their own detection, too. But it should be unique for other phones with same manufacturer.
(It's NOT recommended unless your device don't have ro.vendor.build.fingerprint.)
6. Extract framework-res.apk with apktool on another side. (to avoid commited by mistake)
7. Replace <Your device>/res/xml/power_profile.xml to which power_profile.xml for your device.
It will on <Extracted framework-res.apk>/res/xml/power_profile.xml.
Or you can find whoever's device tree, it may have this file, too.
8. Edit <Your device>/res/values/config.xml
Find each key on following files what for your device:
Code:
[Extracted framework-res.apk]/res/values/arrays.xml
[Extracted framework-res.apk]/res/values/bools.xml
[Extracted framework-res.apk]/res/values/fractions.xml
[Extracted framework-res.apk]/res/values/integers.xml
And then replace values into <Your device>/res/values/config.xml
9. Add your device into <Path of repository>/overlay.mk
Just write like other lines.
10. Build overlays
Just execute following commands:
Code:
chmod u+x [Path of repository]/build/build.sh
[Path of repository]/build/build.sh
If You get this, Do what it said:
Code:
Please install aapt (apt install aapt should do)
Or if you get this:
Code:
OpenJDK Server VM warning: You have loaded library /root/overlay/vendor_hardware_overlay/build/signapk/libconscrypt_openjdk_jni.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.conscrypt.NativeCrypto.get_cipher_names(Ljava/lang/String;)[Ljava/lang/String;
at org.conscrypt.NativeCrypto.get_cipher_names(Native Method)
at org.conscrypt.NativeCrypto.<clinit>(NativeCrypto.java:764)
at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:56)
at org.conscrypt.OpenSSLProvider.<init>(OpenSSLProvider.java:49)
at com.android.signapk.SignApk.main(SignApk.java:942)
I have no solution, either. Try to build on another computer.
11. Test overlay with tests.sh and yourself
For general checks (symtax, etc.), just execute following command:
Code:
chmod u+x [Path of repository]/tests/tests.sh
[Path of repository]/tests/tests.sh
You should fix errors what reported for your device, and then restart from step 10.
If it reported errors but not for your device, just ignore it.
When check passed, you can find overlay file on <Path of repository>/build/treble-overlay-<Manufacturer of your device>-<Name of your device>.apk, just copy it into your phone's /system/overlay/, and set permission to rw-r--r-- / 0644.
And then reboot your phone to test your overlay.
12. If it works for your device, don't forget to perform a pull request for phhusson/vendor_hardware_overlay, to support his awesome works.

Thanks for the guide @minadzuki
but i'm getting this error after step 10:

Oh...I forgot this, sorry.
Because I haven't encountered this error, so I don't have a way to solve it, either. (I tried to built it on three remote servers only)
And...is it cause segment fault?
Or you can try to install google-android-build-tools instead of aapt. (because I can't find aapt on archlinux but found this)

Very nice guide, thanks!
I'll link it as part of a "how to contribute"
For aapt, there is an aapt included in the git. If it doesn't work for you (like @king1990's segfault), know that the one included in the git has the lowest priority. It will pick up aapt from the system first.
(but then you'll need to have a system-wide aapt).
Or if you have an Android SDK somewhere, you can set your PATH to include it.
Edit: I just realized that what I just described might actually be the issue. If there is a system-wide aapt, it will use the libc++ in the git, which would explain the crash.
I fixed this case in my current git.
If there is a system-wide aapt it will use it.
If for some reason, system-wide aapt isn't suitable, you can run build.sh with --local-aapt to force the use of the in-git aapt (i.e. it will have higher priority than system's so no conflict should happen)

Could you check again with latest git?
If it still doesn't work, can you try to call build.sh --local-aapt ?

@phhusson Thanks now it working fine and building without faults
I have few questions regarding the AndroidManifest.xml :
1- for android:requiredSystemPropertyValue how do I know which name to use ? is it trial and error ?
2- for androidriority does matter which number I choose ?
3- some vendors have this overlay (framework-res__auto_generated_rro.apk) under "vendor/overlay". Does is affect the device overlay in system/overlay ?
4- to install the overlay is it just as @minadzuki says ?
and thanks again for your great work

1. For example, Xiaomi Mi 6X has this fingerprint:
xiaomi/wayne/wayne:8.1.0/OPM1.171019.011/8.7.12:user/release-keys/
So you can take xiaomi/wayne to use, and android:requiredSystemPropertyValue will be: +xiaomi/wayne*
2. it will affect to build images, or affect the detection on System. If you got this:
Code:
F: .xxx/AndroidManifest.xml: priority xx conflicts with another manifest
You just take next number and try again, until now priority 53 has been taken (without pull request), you can take priority since 54.
3. Sorry, I don't know for this.
4. Yes, just simply copy and permission change.

overlays in /system/overlay and /vendor/overlay are the same thing, and on my GSI both are loaded, so yes it affects it.
But if your vendor has a framework-res__auto_generated_rro.apk, you probably don't need an overlay file for your phone, because it's already there.
(Please note that /system/overlay doesn't exist in AOSP, that's a change specific to my ROM, and custom ROMs based on it. AOSP only has /vendor/overlay)

@minadzuki Thanks for answering my questions. @phhusson its clear now , I don't know if this is related to your treble approach or not but some GSI ROMs refuse to go the minimum value in the brightness curve no mater what value I set in the curve, it never achieved.
is this treble or ROM related ?

Brightness is a bit complex on Android Pie... (well it already was before, but it got even worse)
Do you have a link to your current overlay, so I can take a look at which code path you'd go to?
What's the lowest backlight value you get in /sys/class/backlight/panel0-backlight/brightness or /sys/class/leds/lcd-backlight/brightness?
Also what's your device? Does it have extended brightness range? (what's the value of getprop persist.sys.qcom-brightness // is it a samsung device?)

for overlay this the extracted files from the overlay apk (my device is Axon7)
The lowest backlight is 10 (once manually edit it to 1 it goes to really dim brightness)
what I don't understand that I already built two GSI ROMs one is DU13 & other Liquid pie both report the same backlight light value at 10 at minimum value but in DU its very dim and in liquid its still bright ?!
The command did not give back any information so I assume we don't extended brightness range.
Thanks
Edit : it was overlay problem , fixed after modifying it

I tried to create an overlay for my Honor View 10 (Berkeley)
Is there a list of recommended settings to copy over from the stock ROM? I started with copying everything listed in tests/knownKeys and it seems to work
There's a power_profile.xml in the framework-res.apk I dumped from my stock ROM but the battery capacity is set to 1000 instead of 3750. Is that right?
There's also a power_profile_test.xml in there with a much more sane value of 3000 mAh. Should I use this one instead?

On Huawei, you'll find real power_profile.xml somewhere in /odm or /product. I'd say /product/etc/power_profile.xml

Yes, you can write source code everywhere (don't forget to replace CRLF to LF), but maybe you should build it on Linux, or you have a way to build it on Windows (e.g.: WSL, Mingw, etc.)

@minadzuki I can't find a config.xml in my framework-res.apk, am I missing something? or that gets created somehow in the process?

on step 5 you say to edit AndroidManifext.xml, does that means delete everything in it and copy paste what you put on the code box? or just add that at the end of the xml file?

framework-res.apk doesn't contain config.xml, it split into several files: arrays.xml, bools.xml, fraction.xml, integers.xml. just create config.xml or copy from other devices and find values on these files (to replace it).
and step 5, just replace values which for your device, like what other devices wrote.

thanks for the response but I am really lost here those 4 xml has way to much data in it, should I just copy everything to config.xml?
to be honest what I am trying to fix are 2 things the battery stats not showing and the auto brightness and brightness slider and if the led light is fixable by an overlay that too, I can provide you all the files needed could you build it for me please? my device is an HTC U12+
