There was some IMPORTANT missing steps that I was able to figure out and lay out a proper step by step guide.

Step 1: Make sure you disable Driver Signature if you're running on Windows 8-10: HERE

Step 2: Download and install correct Flashtool Version and install HERE

>>>>CORRECT FILE SHOULD BE flashtool-0.9.18.6-windows.exe 119MB

>>>>Install 3 drivers, from C:\Flashtool\drivers (Fastboot Mode, Flashmode, Xperia Z3 Device Driver) - If all install successfully, you successfully disabled Driver Signature.

>>>>Driver pack verstion v1.8(20141101)

Step 3: If you do not have build # 23.0.E.0.376, download this firmware and place it in C:\Users\(YourUser)\.flashTool\firmwares

>>>>NOTE This was a little confusing since the 0.9.18.8 FLASHTOOL is the one that creates the Firmware folder in .flashtool

>>>>DOWNLOAD FROM HERE (Otherwise Skip This Step)

>>>>FILE NAME D6708_23.0.E.0.376_VER.ftf 1.54GB

Step 4: Download this file , and place it in your SD card or Internal Phone Memory. You will need this in a later process (Do not Unzip) :

>>>>DOWNLOAD FROM HERE

>>>>FILE NAME flashable-prerooted.zip 1.54GB

>>>>Copy file to SD

>>>>Placing file in Internal Storage causes problems during flash.

Step 5: Download this, it will be used to root when you have Build # 23.0.E.0.376:

>>>>DOWNLOAD FROM link bad at Youtube page.

>>>>I BELIEVE THIS IS THE FILE HERE

>>>>FILE NAME D6616_ROOTFULL.ZIP

>>>>Unzip to same Download folder. Creates folder called D6616_root

>>>>The video uses a file called D6616_ROOTFULL.zip so I was able to find the file.

Step 6: Download this to install DualRecovery Click XZ Dual Recovery, then XZDualRecovery 2.8.21, and download the second one on the list, which is an installer.

>>>>DOWNLOAD FROM HERE

>>>>FILE NAME T2U-lockeddualrecovery2.8.21-RELEASE.installer.zip 24.9MB

Step 7: Flashing Steps

Launch FLASHTOOL

At this point your Phone should say its Android 4.4.4 Build 23.0.E.1.44

WAIT

If Phone asks to Allow USB Debug, click YES

Select D66XX Sony Xperia Z3 and double click

Click YES to continue

WAIT

Copy flashable-prerooted.zip to Phone SD Card. >Copying to Internal causes problems during flash<

Hit any key to continue again and wait for all the commands to finish

Phone with auto Restart

Phone is now ROOTED!!!

SuperSU is now installed on phone

Check ROOT access by opening SuperSU. If file opens properly you have access. If not you will have to retry.

Click Install

Find the flashable-prerooted.zip file you copied earlier

Swipe to Confirm Flash

Allow Phone to install Firmware

Click REBOOT SYSTEM

Wait for Phone to boot, takes a while. About 10 minutes

You now have a Sony Z3V Rooted with Lollipop Android 5.0.2 Build 23.1.D.0.509 on your phone!!!!!!

You can access TWRP by clicking Power + Vol- during boot or use the Quick Boot app

IF PHONE GETS STUCK AT SONY BOOT LOGO, TRY AGAIN AND DOWNLOAD FLASHABLE-PREROOTED.ZIP FILE AGAIN. Since both files are so big you can expect errors in the download.
