This always doesn't work with all devices !!!
Like in my mediatek device I have to flash a logo.bin file to a specific partition to change the boot logo but I couldn't find any good boot logo so stayed with the stock one !!!

Thank you for this! I'm currently building an iOS rom for the SM-T113 (all regions) and I've been needing a tool to change the first boot image. I'm also changing the boot logo as well so for those who would like to try i'll be writing a thread sometime this week once i have the beta done. It won't be fully iOS due to the problems of crashing apps when i re-compile them, but i'll be updating it every week or so to fix bugs and need testers as well.

-installed cygwin
-the full boot.img/kernel (some kernel won't work because there is no full pakage/ i mean we can't) (tool for UNPACK and REPACK kernel)

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 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

5-Now, unpack your boot.img by running the following command:

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.

Special thanks/credit to jimbo77 for his excellent guide
