Note: I'm just sharing the work of the XDA Member CNexus.Here's a little introduction by him :

I have not seen this posted anywhere, so I thought I would post it here. This is NOT purely my work, and I do not take credit for it as such.
Included in the attached ZIP are the following files:
boot_info - prints information about the boot.img passed to it, including the base address and ramdisk address. This tool prints out everything needed to repack the boot.img correctly.
split_boot - More commonly known as split_bootimg.pl, this rips apart the boot.img to extract the ramdisk and zImage. It has been modified by me to split the boot.img into a separate folder (specified by the file name of the boot.img passed to it) and to extract the ramdisk into a sub-folder as well (extracts the cpio from the gz and then extracts the actual files from the cpio archive)
unpack_ramdisk - unpacks the given ramdisk file.
Code:
Usage: unpack_ramdisk
repack_ramdisk - repacks the ramdisk from the given directory (found online and modified slightly to take a directory)
Code:
Usage: repack_ramdisk [outputFile]
mkbootimg - mkbootimg binary that creates a boot.img file from the given ramdisk and zImage. Updated to a version compiled by me to support the --ramdiskaddr option (ramdisk address) so that even nonstandard boot.img's can be repacked correctly (Use with boot_info for best results).
umkbootimg - included for convenience. Not made by me. Original thread here.
unpack - wrapper script made by me for the umkbootimg binary^ to unpack the boot.img into a separate directory and then unpack the ramdisk into a sub-directory.
Note: These tools were made for Linux. They may also work on Cygwin, but I have not personally tested them.
ANYONE is free to use / modify / kang these files as they see fit. No need to ever ask or do anything more than download.
Enjoy.

How i solve Error:NO ramdisk folder found.
Are you have trouble extracting from the phone or extracting the .img file into something editable? I see at the top of the first page here that there is an update to the Kitchen. Maybe the newer version supports your phone better?
Hello,
I was able to unpack the image simply by using the command
Code:
unrar x system.img
Now that I have made my modifications (literally only changing the build.prop to start) I need to repack the system file folder back to an "x-raw-disk-image". Does anybody know how I may do this? Thanks everyone!
