Then... Shouldn't it be either deleted or unstickied?

It'd be great if we could revisit this and update it!

hit the "REPORT" button on the first post and highlight it to a mod.

As for updating, I don't think it would be possible / practical on newer more complex android. HOWEVER, android now has the feature basically baked into some devices using GSI.

Done.

Are you aware of a generalized GSI thread?

Cant say I have. I think XDA forums/threads are built to be device specific not generic. There may be one, but I myself come here looking for device specific info. They have news stories/articles that would contain more generic info. But its only good for background info, not to apply to a specific device ie not step by step instructions for all devices.

    Tools Required : (Update them manually and report me dead links please)
    Click to expand...
    Click to collapse


    Step one: Installing the JAVA JDK, Cygwin and Setting up the Kitchen.

    *Before you do anything install the java jdk*

    Try this Dsixda Kitchen Install Picture Tutor(recommended)

    OR

    watch this video tutorial by gitagaire for how to setup cygwin and kitchen(recommended)
    Click to expand...
    Click to collapse


    INSTRUCTIONS

    • Download and extract the cygwin_packages.zip
    • Run the set up(make sure there is no previous cygwin installation)
      NOTE: INSTALL CYGWIN IN ROOT DISK LIKE C:\
      • Follow the kitchen read me txt!!!
      • local package directory *must* be the path to the cygwin_packages folder that you just extracted

      • unledwkc.png
      Click to expand...
      Click to collapse
    • when it shows all the package names, go to the top and select "all default" until it changes to "all install" (you must click on the arrows)
      unti1led.png
      Click to expand...
      Click to collapse
    • Download the kitchen from above. Then, extract the kitchen's .zip file to a folder under your home account. Rename the dsixda-android-kitchen-*** folder to just "kitchen". In Cygwin, this folder would depend on what was set for your Cygwin install directory, e.g. C:\cygwin\home\John\kitchen
      NOTE!! If your user folder contains spaces (e.g. C:\cygwin\home\John Smith\kitchen), then the kitchen will not function properly. Instead, copy it under C:\cygwin\home\kitchen.
    • Now your ready to run the kitchen type:
      those who have their kitchen like this C:\cygwin\home\John\kitchen use these commands given below.
      cd kitchen(enter)
      ./menu(enter)
      Click to expand...
      Click to collapse
      those who have their kitchen like this C:\cygwin\home\kitchen use these commands given below.
      cd ../kitchen(enter)
      ./menu(enter)
      Click to expand...
      Click to collapse
      Click to expand...
      Click to collapse
      If you did things right you should see this:

    Step Four: repackage the rom


    • AFTER YOU HAVE DONE ALL CHANGE/MODIFICATION YOU WANTED OPEN CYGWIN AGAIN AND TYPE
      cd kitchen(enter)
      ./menu(enter)
      Click to expand...
      Click to collapse
      now convert update script to updater script(in option 23)


    • now lets edit updater script(optional)

      Thanks to user langthang for a great updater-script guide.
      Download it HERE
      Click to expand...
      Click to collapse

      the updater-script basically tells CWM what steps to take during the installation(flashing rom).
      If you don't have any experience please don't edit anything other than what is in this simple tutorial.

      TO EDIT UPDATER SCRIPT -
      1.Go to META-INF/com/google/android
      2.Open the updater-scrip file with Notepad++
      3.Any text that would appear during the CWM install should be in this format :

      Code: 
      ui_print("Put your text in HERE");

      Add your text start at top and save,
      then replace with new updater-scrip
      unledofd.png


      IF YOU GET ANY ERROR YOU CAN COMPARE YOUR UPDATER SCRIPT WITH MINE (attached in 1st post)
      NOTE: DO NOT COPY WHOLE UPDATER SCRIPT JUST EDIT PART WHERE YOU GET ANY ERROR...
      most common errors will be in mount, remount part in starting and end and boot.img installing part... so replace only those lines....



      AND AT LAST

      [*]Now that you have made some changes it's time to pack the rom and test!!


      1. Run the cygwin and type
        cd kitchen(enter)
        ./menu(enter)
        Click to expand...
        Click to collapse
      1. enter option 99 - "biuld rom from working folder"
      2. Choose your build option and few more enters
        I recommend that you go with all default options until you get more experience with the kitchen.
      3. When rom is packed and signed it will ask to change rom zip name (type name of your rom)
      4. When its all done you will find a folder inside "cygwin/home/yousername/kitchen" called output_zip
      5. Inside the folder is your new rom ready to be flashed and tested!!!
        unledwxh.png

      IF YOU WANT THAN YOU CAN MAKE CWM FLASH ABLE ZIP'S MANUALLY USE THIS TOOL BY I.AM.H3RO


      congratulations you have build your own rom

    • TROUBLESHOOTING (by hell_lock)

      • If you are facing java related problem with cygwin than refer to this post. and Google search
      • If you get problems in installing a rom then compare your updater-script in META-INF folder with one attached in first post.
      • If you have a rom without kernel then remove these lines:
        Code: 
        assert(package_extract_file("boot.img", "/tmp/boot.img"),
       write_raw_image("/tmp/boot.img", "/dev/block/mmcblk0p8"),
       delete("/tmp/boot.img"));
        NOTE: mmcblk0p8 can be different with different devices... this works fine with galaxy ace plus...
      • If there is a package error then extract the files of the rom and repack them using any compression software.
      • If rom installed correctly but stuck onto logo screen?? Then remove try removing kernel and flashing rom again.
      • If rom installed correctly but got onto bootloop then there could be many possibilities which could lead to this. If you want accurate cause of it then do a logcat.
      • If there are some apk's which are not working then check if you correctly modded them.
      • For status errors like status error 0, status error 6, status error 7 see this guide by Tha TechnoCrat and for rest go here and type your error.

    NOTE: Most of the problems occur because of updater-script problems so before trying any of the troubleshooting try the first tip.

    Step Two: Setting up a working folder


    THERE ARE TOW METHODS FOR THIS.
    1. WHEN YOU HAVE BASE ROM AVAILABLE.
    2. WHEN YOU DON'T HAVE BASE ROM.

    FIRST METHOD -
    • First our folder structure should look like this:
      Code: 
      cygwin folder/home/your user name/kitchen
    • Inside the kitchen it should look like this:
      unledmlb.png
    • Now we need a rom to work on, for GALAXY ACE PLUS[s7500] users i will recommend this rom by blackburner but you can use any rom.
      Just Place the original rom zip in the original_update folder inside the kitchen.
    • run the cygwin.exe again type:
      Code: 
      cd kitchen(enter)
./menu(enter)
    • now enter option 1, enter again. You should see your rom listed, choose and enter
      you will be asked about changing the working folders name, at this point it makes no difference so just continue.
    • congratulations you have a working folder!!!
      unledzfr.png



    SECOND METHOD - this method is by neroyoung

    FIRST MAKE A WORKING FOLDER IN CYGWIN FOLDER
    IT SHOULD LOOK LIKE THIS
    cygwin folder/home/your user name/kitchen/WORKING_(your rom name)
    Click to expand...
    Click to collapse

    NOTE: FOR THIS MEETHOD WE NEED 3 FILES AND FOLDERS TO BE PLACED IN WORKING FOLDER.
    1. META-INF FOLDER - GET THIS FROM DOWNLOAD FILES LIST IN FIRST POST
    2. SYSTEM FOLDER - TUTORIAL BELOW
    3. BOOT.IMG - TUTORIAL BELOW


    2. getting system folder
    (NOTE - YOU MUST BE ROOTED FOR THIS MEDHOD)
    • This is universal method and can be done easily using terminal emulator.
      For this simply download Terminal Emulator from Android Market.
      we need freshly flashed device here. OTHERWISE YOU WILL HAVE LOT OF JUNK FILES.
    • Open it and type:
      su
      tar -c system/* >> sdcard/system.tar
      Click to expand...
      Click to collapse
      This will copy all your /system folder to your SDcard with name System.tar
      This will take some time to finish so be patient.
    • After it's done you should have a tar file in your /sdcard named system.tar
      You can extract it using Winrar or 7zip software. But yes this will have huge size , as it has other useless folders so you will have to delete them. After extracting this system.tar file you will get following folders (Similar one)

      • /etc
      • /fonts
      • /framework
      • /lib
      • /lost-found
      • /media
      • /sd
      • /semc
      • /usr
      • /xbin
      • build.prop
      • And some other files and folders like ""autorooted,kernel files" etc
      Click to expand...
      Click to collapse

      Now simply delete the folders marked in red color and its done.Don't worry if you don't have folders with red colors above,we don't need them.
    • And the final files that we will have in our system folders will be

      • /app
      • /bin
      • /etc
      • /fonts
      • /framework
      • /lib
      • /media
      • /semc
      • /usr
      • /xbin
      • build.prop
      Click to expand...
      Click to collapse
      If it dont have semc folder no need to worry.
      NOTE: YOU CAN ALSO GET THIS SYSTEM FOLDER BY USING ANY ROOT BROWSER. JUST FIND THIS FOLDER AND COPY/EXTRACT TO SDCARD
    • NOW COPY THIS system FOLDER TO WORKING FOLDER


    3. getting boot.img

    Here we have 2 options
    1. stock boot.img from stock rom - simple kernel which we get in brand new mobile.
    2. custom boot.img from custom kernel - kernel which are modified for overclock or other features

    1. getting stock boot.img from stock rom.
    extract your stock rom with winrar or 7zip. you will see boot.img there. copy it to working folder

    2. getting custom boot.img from custom kernel.
    • download any custom kernel which is only for your device. [galaxy ace plus [s7500] users get from here or here]
    • extract it with winrar or 7zip and copy boot.img to working folder
    NOTE: many of new devices have kernel.bin and other files instead of boot.img so skip this part if your device don't have it...

      HERE YOU WILL FIND 3 ROWS...
      1. As you can see, there are different attributes assigned to each key. like this
      Code: 
      key 102   HOME
key 139   MENU
key 158   BACK
key 115   VOLUME_UP
key 114   VOLUME_DOWN

      2. Specific application/action launchers:
      Code: 
      HOME                     #Launches "Home"
MENU                     #Launches "Menu"
BACK                     #Takes you back to the last activity
SEARCH                   #Launches "Universal Search"
CALL                     #Launches the "Phone" activity and corresponding .apk or initiates a call
ENDCALL                  #Ends a call
CAMERA                   #Launches "Camera" activity and corresponding .apk
FOCUS                    #Initiates Auto-Focus while using the Camera
VOLUME_UP                #Self explanatory
VOLUME_DOWN              #Self explanatory

      3. And attributes saying if it should wake the phone at button push to complete the action, or if it should just complete the action without waking the screen.
      Code: 
      WAKE                 #Completes the action without waking the screen
WAKE_DROPPED         #Wakes the phone to complete the action
      Click to expand...
      Click to collapse

      2. NOW WE WILL EDIT SECOND AND/OR THIRD ROW
      Erase the center row value for any key to completely disable it. To reassign the key, replace the center row value with another one from the same row. Change the right row value to either "WAKE" or blank to enable the wake function. Do not modify the left row.
      NOTE: don't edit left row i.e. first row which contains specific key identity number.

      FOR EXAMPLE I DO THESE CHANGES
      DEFAULT VALUES ---
      Code: 
      key 115   VOLUME_UP         WAKE
key 114   VOLUME_DOWN       WAKE

      CHANGED VALUES ---
      Code: 
      key 115   CAMERA         WAKE
key 114   FOCUS          WAKE

      NOW VOLUME UP KEY WILL WORK AS CAMERA KEY AND VOLUME DOWN KEY WILL WORK AS FOCUS KEY....
      NOTE: all words should be in BOLD letters i.e. capital letters...
