The following guide should work for all loki-locked bootloaders, but I can only confirm that it worked on my D800. The problem I was having, was that loki_flash has been replaced with loki_tools, and there arent any guides out for loki_tools.

The right way to flash CWM requires you to generate your own recovery.lok from the aboot.img, and recovery.img (CWM) which you need to use loki_tools for.

PREREQUISITES​

Device must be rooted

Device must be in Developer Mode

USB Debugging turned ON

Debugging RSA Signature must be accepted

Download CWM HERE

Download loki_tool HERE

Download ADB HERE

STEP 1 (Getting Files)​

Follow this GUIDE to install ADB and FASTBOOT, once its complete, you will have adb installed to

C:\adb

Download CWM, rename the file to '

recovery.img

' (so its easier to work with) and move it to

C:\adb

Download loki_tool and extract the file '

loki_tool

' from the

bin

folder and place it in

C:\adb

STEP 2 (Preparing for the Procedure)​

Plug in your phone to the computer

In Windows Explorer, navigate to C:\

Shift+Right Click on the 'adb' folder, select 'Open command window here'

Type "adb devices" you should see:

C:\adb>adb devices
List of devices attached
<devid> device

If not, go back and turn on Develper Mode, USB Debugging, and accept the RSA Signature

STEP 3 (Flashing process)​

(note: I copied everything from the cmd prompt and edited it as a text file before thinking to post my procedure here, thats why it looks different)

In ADB type the following commands each step is commented out with what it does (someone could make it into a bat, but I'm too lazy.
