I followed the thread by deej_roamer here http://xdaforums.com/showthread.php?t=2755336

Try out my steps:

[Your phone battery must be at least 75%]

1. First download "Fastboot" from the thread. (Click on the "mfastboot-v2" link in the thread)

2. Next install it in a folder and remember that folder. Also, make sure you select the option of "Create shortcut on Desktop" during installation.

3. Next download CWM recovery from this thread - http://xdaforums.com/moto-e/general/root-moto-e-rooting-flashing-recovery-t2802971 (Click on the "CWM 6.0.4.9 recovery For MOTO E" link in the thread)

4. Copy the "cwm6.0.4.9_recover.img" file to the installation folder of fastboot.

5. Next download SuperSU v2.02 from here - http://download.chainfire.eu/452/SuperSU/UPDATE-SuperSU-v2.02.zip (Click on "UPDATE-SuperSU-v2.02.zip" link)

6. Don't Extract Supersu zip file.

7. Connect phone to pc. Copy the zip file to your internal memory(the directory of int. memory is /sdcard) (The directory for ext. sd card is /storage/sdcard1).

8. Remove your phone from your pc.

9. Switch off your device.

10. Turn on your device by holding power off button and volume down button together for 6-7 seconds. Quickly connect your phone to your pc.

11. The bootloader must be showing usb connected.

12. Run fastboot from your desktop.

13. Now type this (without quotes) - "fastboot flash recovery cwm6.0.4.9_recovery.img"

14. Look at the screen of device. It must be showing "Mismatched partition size (recovery)". It is normal don't worry.

15. Press volume down once (recovery will be selected) and then volume up so that it goes into recovery.

16. It will show the bootloader unlocked warning. Don't worry about it.

17. Your phone should now be in CWM recovery.

18. Don't do anything except what I tell you.

19. In this menu movement is done by the volume rockers ans selection by power button.

20. Press volume down so that "install zip" is selected.

21. Press power button.

22. Select "choose zip from /sdcard". Press power button.

23. Find the SuperSU.zip file(It will probably be in the "0/" folder)

24. It will ask to confirm install. Select Yes.

25. SuperSU will be installed.

26. Select CWM reboot. When you select CWM reboot, it will display "root access possibly lost - Fix?". PLEASE Select "No".

27. Your phone will now reboot. (The bootloader unlocked warning will be shown and then the boot animation).

28. Open your menu(in the phone) and find SuperSu app (a # symbol will be there in its icon).

29. Disconnect your device from the pc.

CONGRATULATIONS YOU HAVE A ROOTED MOTO E.

If you ever wish to flash any other recovery (like twrp),

1. Copy the file to the fastboot installation folder in your pc.

2. Then reboot your device into bootloader and quickly connect it to your pc.

3. Run fastboot from your desktop and then type the following without quotes: "fastboot flash recovery cwm6.0.4.9_recovery.img"

4. Instead of writing "cwm6.0.4.9_recovery.img" write the complete file name including extension. For eg. if file name is "twrp_recovery_2" and has extension ".img" then write "fastboot flash recovery twrp_recovery_2.img"

I hope that this solved your problem brother.
