Fully bricked Nexus 7 2012, not the same brick as always. Just read it.

I have read every single thread that exists on the internet about this problem, the bootloops, the faulty bootloaders, the wrong rooting and image installations, every single posible way to brick this piece of device that everyone seems to have problems with. Yet none of them has gave me a solution. First of all, it's my girlfrinds tablet, she told me that one day, she tried to upgrade the android software and while it was installing it, the tablet bricked. She was able to go to fastload mode (power + volume up) we've tried recovery mode, factory reset, every option there, nothing. She gave me the tablet, I plugged it on my pc and used Nexus Root Kit to install a new android software to the device. After a painful search of how to make the Kit recognize the tablet because usb debugging was not on, I was able to start the process of installing the new software. Yet, in the middle of the installation, the micro-usb moved a little bit and the tablet got disconected. The process was cancelled and the tablet screen froze. I turned the tablet off and that was when it just bricked and never wanted to turn back on. Neither with any combination of the buttons, nor while leaving it charging a long time, nor any possible solution the internet may have about this. Just fully totally and simply bricked. Yet, when I connect it to my pc (windows 7 ultimate 64 bits) sometimes, it reads it as an unknown device, sometimes it reads it as a random APX device, and when I install any kind of drivers that already exist on every thread that there is about it, it reads it as an ASUS Transforme Prime APX Interface, yet the tablet never displays anything, and I'm not able to access it in any way nor make any changes to it whatsoever. I live in a country were there is no google or asus techical support, and third-party technical supporters are dumb as f***. My girlfrind took the tablet to 2 other places before giving it to me and they said to her that "it didn't have any software installed" (which was wrong) and that "it was beyond repair" (which was also wrong). The only thing I want to know is: is there any way to fix it now? or do I just have a very nice and fancy paperweight in my hands.
