Hey guys,
I am trying to repack the stock kernel as I have made a change to the ramdisk (ro.secure=0) I wasn't able to split the boot.img using split_bootimg.pl as it could not find android magic in the header so used flashtool to extract the kernel.elf file which gave me 3 files.
These were "kernel.elf.Image" "kernel.elf.ramdisk.gz" and "kernel.elf.3"
I have managed to extract and make the changes to the ramdisk and recompile it but im stuck at merging these 3 files back into the flashable kernel.elf file any help would be much appreciated

Who? Me?
@DanielFlorin You want to decompile or recompile? To decompile, use Flashtool. Go to Tools > Extractors > Elf. You'll get a ramdisk, a bootcmd and a boot image.
If you want to add CWM or TWRP, change the ramdisk with whatever kernel you want.
If you want to add overclock, build a new kernel boot image (you'll need Linux for that). Follow this guide: http://forum.xda-developers.com/showpost.php?p=50651922&postcount=46, but change msm7627a to msm7627a-perf everywhere in the guide.
Now, to recompile, rename the ramdisk file to ramdisk.cpio.gz and the boot image you compiled to zImage. Now on a Linux machine, get this script: http://forum.xda-developers.com/xperia-j-e/orig-development/tools-build-kernel-elf-ics-t2532724
(If you don't know how to, just run this command:
Code:
git clone <link>
where <link> is the GitHub link in the thread)

Mostly we want to update zImage in boot.img. so suggest you not to go for unpack and repack. just update your custom zImage into defualt boot.img by running this command:
#abootimg -u boot.img -k zImage.
Then try to flash this boot.img in your phone. If you are r changing initrd.img also then you can go for unpacking and repacking
but always take backup of your default boot.img, because if anything gone bad with this custom boot.img then your defuault will help to bring back your phone.

I am making an customized version of Stock ROM so I decompiled the 4 sparse files and did the modifications I wanted to,so now I have so make it a Flashable Zip to install it For that process I have to Make the System in System.new.DAT like CM or System.IMG or I can push the System directory directly in the Zip to sign.
Any attempt to help will be appreciated.
Hello all, I want to make a custom ROOM STOCK for Samsung devices so that it can burn in odin but all the tools (Tool Unpack Repack DAT + IMG) that create the file system.img require the file_contexts that I do not know how to get it (this is Android 4.1.2. File inside the boot)
I realized that I use the make_ext4fs file only because I do not know how it can be used by anyone who can help. I will thank him very much.::
