I think we've got the same thing. I've got the most basic m96. It was bought from Artatech but I flashed the device and moved to booxtor/international version at some point. Right now I'm running 1.7.5_da062b6.
towelroot.com is probably the official site. However, I used the file from here:

Apparently the v1 version of towelroot is no longer available on the official site.
On some previous firmwares the device froze after clicking on "make it ra1n", but on the 1.7.5 it didn't. I think I restarted the device anyway. SuperSU sees the root, and I disabled some of the system apps with SystemAppRemover.
