that is because there is not any please just use the script I linked to in the OPPardon my assumed ignorance but I do not see instructions for just an ADB install of the TWRP without the loki install.
the reason is is that you need to push the aboot,img from v50010a for loki to work and I am not going to post instructions on how to do that. it is not the safest way to do things and we need loki because our bootloader is locked. if you really need to do it manually you can find all the commands in that script. I just want to see people pushing the wrong .img to the wrong partition possibly ending up with a hard brick.
Please just use the script from this thread scroll down to step 3 http://forum.xda-developers.com/show....php?t=2698267
