Romdump is a (very) simple program that dumps the boot, recovery and system partitions to your SD card, this will allow someone who is technicaly minded to create a recovery image.

First, you need a rooted device before you can begin the process. After you have rooted it, you have download from Play Store an application called 'Android terminal emulator'.

Next, copy the 'romdump' file to your SD card and put the sdcard into your device. Copy and paste the romdump file to /data/local/ (open root browers /root access file manager and then go to data folder and then open local folder and paste the file romdump). Change the permission of the romdump file (using ES File Explorer --> Hold the file --> Properties --> and change it to 755 (rwxrw-rw).

Created a folder name 'romdump' in SD card.  Open the installed android terminal emulator app and use to following command:

su
/data/romdump

# chmod 04755 /data/local/romdump
# /data/local/romdump
