No "flash zip from SD card" option on ClockworkMod Recovery I am trying to follow the steps outlined in the following article in order to root my Nexus 4 running Android 5.1:

Step 13 instructs that I apply SuperSU with a "flash zip from SD card" command; however, no such command is appearing on my ClockworkMod menu. I have an "Install ZIP" option, but I am not sure whether or not this should accomplish the same function.

I am running ClockworkMod Recovery v6.0.4.7 (Touch).
Use the Install Zip &rarr; select the zip file you downloaded (possibly this) &rarr; choose Yes if asked, and the recovery should flash this zip into your system.

Flash zip from SD card or Install zip are basically the same thing.
