Notebook Video, Display and Touch

Hey all,

My Spectre's touch screen stopped working after trying to upgrade its firmware.
I was looking for a newer firmware version to make the stylus work, but after running the software I got a red screen, it rebooted and never worked.
I called HP support and they told me it is a hardware problem, however the hardware is detected correctly when I boot it with a Linux distro. Looks like it's a matter of having the correct firmware or driver to make it work again.
I looked everywhere for a firmware update or a tool to diagnose it, but I had no luck.
HP support here in Brazil says they can't do anything, even if I have a global coverage. Taking it to the US for support is out of question.

Any thoughts?

Thanks

Here's the lsusb -v output for it.
