I have copy pasted the page for the asus-t00f for now, will edit later, they are basically identical devices.

How to enter flash mode
Hold power button and volume up while device is turned off

Installation
Zenfone 5 uses non-standard bootimg format, so we'll need to create it manually. You'll need a working Zenfone 5 boot.img to proceed.

Then you can flash output_boot.img as you normally would using fastboot.
