Setool2 for w760a

I have a w760a from At&t USA. I need to debrand and unlock it.

However, I couldn't install the usb driver.

I use this guide to install usb driver

USB Flash Driver Installation - Guide - Top Sony Forums

It didn't show up the find new hardware at all, and there is no new hardware at Device Manager so I couldn't install it the fist way. So I move ggsemc.sys in C:\WINDOWS\system32\drivers

And when I try to connect XS++ it with my phone, I counldnt open the communication pot ( I try to install the usb driver and everytime I connect, the computer recognize the phone, but not xs++).

Besides, when I use setool2, there is no w760a in the list.
So how can I use setool2 to debrad and unlock it?

I can use xs++ to debrand it, but I dont know how to apply patch with xs++


Another question off topic: I need w760a, newest firmware (R3EA037 I guess), APAC 1 (English, Vienamese, ... ), so how can I name my FS, main firmware and custom file and where I can find it (in the download section, they dont have R3EA037 for APAC.

Thank you all.
