Is it possible to update Sony z3V using the Sony PC companion app for Windows?

I believed I messed up somewhere in updating to the latest lollipop firmware and now it wont get go beyond the verizon logo. I have twrp installed and even thou after installing the pre-rooted zip it just wont work. I am trying to go back to stock firmware but I am also having issues with the flashtool havent looked too much on the driver issue I know people have experienced the same thing, but my question is to make things simpler will it be possible to repair the phone using the sony pc companion tool? I believe is not supported since I cant find the model z3v, do I select a Tmobile or Japan model? Thanks.

I know I'm not the only one, but Just starting a thread about not being able to install the Samsung Milk Music Companion App because it says it is not available for your device, even though I have a Gear S2 and an S5.
