Minimal ADB side loading and fastboot flashing.

Ive only started playing with my z2 again after what feels like a year long hiatus though dont count me on that it could be wrong anyway. ive since lost my files and when i first started i used somthing like shimp208's "Minimal ADB and Fastboot" (http://forum.xda-developers.com/show....php?t=2317790) but it required some files added to it to work with the z2, I havnt tried it yet so im not sure if those files whatever they were are still needed but if they are could someone please link me so i can use adb fastboot flashing and sideloading thanks

im using d6503 and windows 10
