How to dump current Android firmware

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 crte a recovery .
First, you need a rooted device before you can begin the process. After you have rooted it, you have download from Play Store an appliion 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).Crted a folder name 'romdump' in SD card. Open the installed android terminal emulator app and use to following command:

$ export PATH=/data/local/bin:$PATH
$ su
# chmod 04755 /data/local/romdump
# /data/local/romdump

After you run that you can copy the whole folder from /sdcard/romdump to your PC (using external sdcard, usb plug-in, etc)
Note: if you get a error about "cannot crte /sdcard/romdump/..." that mns you need remove a file/folder in your sdcard that named as romdump. You will see all the things whats going on below if you see this then you will get the ROM dumped if not then follow the steps once again.
Here is the list of the files you get after running romdump:
