1. Root your phone, which can be done by towel root or by just booting a recovery like he said,
fastboot boot twrporwhatever.img, then flash supersu
2. Boot phone that has stock recovery
3. adb shell
4. su "watch your phone to grant root adb access if you haven't ever done it"
5. dd if=/dev/block/mmcblk0p43 of=/sdcard/recovery.img
6. This will put flashable recovery.img on your internal sd card. Copy this and save it for later
7. "fastboot flash recovery recovery.img" will get you back to stock recovery, "fastboot flash recovery twrporwhatever.img" to flash custom recovery.

In step 3 you have mentioned boot phone that have stock recovery.
where to boot it??
i have to boot my phone in bootloader or boot into system?
and in
step 4. will i find adb shell when i boot into system? and what to do with it?

Another option you have is to go back to fully stock and then extract the bootloader. You can do it here: http://forum.xda-developers.com/show....php?t=2729173 REMEMBER TO PERFORM: FASTBOOT OEM LOCK before doing it or it won't go through.

adb doesn't work in bootloader, you'll want to be booted into system/OS.

shell is an adb command. If you don't know how to issue adb commands, use the XDA site search function using the term "adb easy" and you'll get some quick and easy adb installers and tutorials.

I think you mean "extract firmware".

Bootloader and recovery are 2 completely different things, and different partitions.

I see imminent bricks here, if you aren't 1000% sure what ADB, or Fastboot, or what the exact differences are between them, you should not be using them. ESPECIALLY if you have S-OFF. Just going by some of the posted [clueless] questions; be careful, last thing you want is a $500 paperweight....
