Wanted:XPS 13 9360 Synaptics Touchpad Firmware

Hi guys, I was trying to mess around with the touchpad driver on my new bought xps 13.

I tried with the latest driver on Synaptics website, but it didn't help much.

Then I found a driver on dell website that turned out to be a firmware update. Its for the 2015 version xps 13 so its outdated. I tried it anyways, and then the touchpad stopped working.

Right now the device manager cannot even detect my touchpad, and the firmware version shows from firmware update software changed from 2xxxxx to unknown.

It would be much appreciated if someone can give me the latest/compatible touchpad firmware for dell xps 13 9360. The executive file called SynReflash.exe, and it comes with mup file and package file.
