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.

  1. Device must be rooted
  2. Device must be in Developer Mode
  3. USB Debugging turned ON
  4. Debugging RSA Signature must be accepted
  5. Download CWM HERE
  6. Download loki_tool HERE
  7. 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.

// Sending recovery.img to device
C:\adb>adb push recovery.img /data/local/tmp/recovery.img

C:\adb>adb shell

// changing directory
shell@android:/ $ cd /data/local/tmp

// ls should list the following 3 files, if not, you are missing them and need to push them, or generate another aboot.img
shell@android:/data/local/tmp $ ls

// changing the permissions of the files so loki_tool can use them
shell@android:/data/local/tmp $ chmod 755 /data/local/tmp/loki_tool
shell@android:/data/local/tmp $ chmod 755 /data/local/tmp/recovery.img

// executing loki_tool to generate the recovery.lok file
shell@android:/data/local/tmp $ ./loki_tool patch recovery aboot.img recovery.img recovery.lok
Loki tool v2.1

[+] Original ramdisk address: 05000000
[+] Writing device tree.
[+] Output file written to recovery.lok

// Saving recovery.lok locally in case you need it again
C:\adb>adb pull /data/local/tmp/recovery.lok

// entering Android Linux environment
C:\adb>adb shell

// sudo

// changing directory
root@android:/ $ cd /data/local/tmp

// flashing recovery.lok with loki_tool
root@android:/data/local/tmp # /data/local/tmp/loki_tool flash recovery /data/local/tmp/recovery.lok
Loki tool v2.1
[+] Loki validation passed, flashing image.
[+] Loki flashing complete!

// exiting Android Linux environment
root@android:/data/local/tmp # exit
shell@android:/ $ exit

// reboot device into recovery
C:\adb>adb reboot recovery
At this point your device should reboot into CWM, Congrats!
