Hard Bricked brand new Xiaomi Mi Pad 3. Please help!! - Android Q&A, Help & Troubleshooting

So, I've bought a Xiaomi Mi Pad 3 with a Chinese Rom, and I was following a tutorial to flash a new rom into it.
I basically did the following:
Installed MediaTek Drivers on PC
Opened "Smart Phone Flash Tool"
Specified Download-Agent as DA_SWSEC.bin and Scatter-loading File as the ROM
Unchecked preloader and clicked on "Download"
Connected the Xiaomi Mi Pad 3 to the computer while pressing Volume Down
Then, at this point, the computer crashed with a blue screen of death with the error "BUGCODE_USB_DRIVER". Here is the diagnosis of the error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After that, the Mi Pad won't turn on, won't respond to any button and is not recognized by the computer.... I think I might have hard-bricked it.
I've found a tutorial about recovering a Mi Pad 1, but one of the steps is to make a bridge in the SD Card slot, which Mi Pad 3 don't seem to have.
I'm a developer myself, I know my way on things, I have a VM Linux, I'm willing to open the tablet and do whathever it costs to recover it.
Please, what can I do??

I FUC*ING RECOVERED MY FUC*ING TABLET. FUC* YEAH!!!!!!!!!!!!!!
I don't know exactly what it was, but I kinda did the following:
- Installed the latest SP Flash tool from spflashtool.com on my PC
- Installed Mi PC Suite for drivers and such
- To help debug, I had a freeware called "Free Device Monitoring Studio", to better understand what's going on on my USB ports
- I was playing a little with the connection/desconnection of the device on my computer, trying to understand how it was. I saw that Kali Linux running under Oracle VM kinda recognized it as a Mediatek device, but couldn't do anything else than that. With that info, my hopes went a little higher, because it wasn't completely dead after all.
- I opened Flash tool, configured it to used the same ROM and files I was using when I bricked it, because I'm pretty sure they weren't the cause of the brick and clicked "Download"
- Then I began messing with the tablet trying to make it be recognized by SP Flash Tool, upon turning it on and off and switching USB ports and connecting them directly to the motherboard USB ports instead of the frontal USB ports
- Then at one point it suddenly recognized and started downloading and flashing the new ROM. I faced some errors but with Format all + Download and having to disconnect/reconnect the batery to make it recognizable again and some little tweaks here and there, it ended up working.
My tablet is working fine now
