[Xperia Z3v General] LeifEricson:
Sony XPERIA Z3v D6708

Intro

First, thanks to Pyres for the original Z3 root bounty thread, myself for the Z3v root bounty thread , and tuzonghua for the D6116 root bounty thread , our similarly mistreated sister device. As you all know, the root method created by zxz0O0 has long since granted us Verizon users root on our devices. But it's time we make a new bounty. The last hoorah for our poor little Z3v -- bootlader unlock.

Objective

With root achieved, the main objective of the bounty is to achieve bootloader unlock on the Z3v which, given the fact that Verizon has yet to release Lollipop OTA Verizon took this long to release 5.1.1, and will probably never release Marshmallow, would mean a great deal to us Z3v owners who want to run custom ROMs.

Claiming requirements - Bootloader

In order to claim this bounty, you will need to fulfill each and every one of this points (2 is optional but helpful):

1. Be the first person to create or find a method to unlock the bootloader on this device in any form;

2. BONUS Prove that the TA partition can also be backed up, and later restored with little issue, in order to maintain some Sony features that would be otherwise be lost if accidentally tampered with;

2. Give proof of point #1/#2 by posting an adequate quantity of screenshots to illustrate it, together with step by step instructions, in a fashion such that everyone can follow them and reproduce the exploit;

3. Wait for at least 10% of pledgers (fastest quorum achieved between per capita and per pecunia criteria*) to give confirmation about the method functionality;

4. Claim your bounty via PM from pledgers.

*i.e. the fastest between 10% of the number of people and 10% of the amount of money pledged as bounty.

Payment will be processed between each member and the bounty collector via PM on an individual basis.
