[Q] Repacking kernel.elf help

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

Request help creating a file system.img

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.::
