I'd like to confirm that you can easily root the phone using bencebacsi's image and an OTG mouse to navigate through TWRP. Thanks for the help, bencebacsi!

Thank you for your feedback. I've added this image to the list in the TWRP-root thread with mentioning the restrictions. It means by getting a one-dollar OTG cable anybody can use this TWRP recovery, even if finally we fail at creating a fully working one.
If one doesn't have an OTG cable do you think we can we install this recovery via adb and also flash Super su as system via adb? This way I am assuming we don't need touch recovery to work in order to root.
I've compiled a TWRP recovery with the boot image kernel but I still can't test it by my own. Please try it to see whether the touch screen works or not. recovery-UMI_Super_TWRP3-20160609-1934.img
If this one still doesn't work, megthebest promised to publish a fully working TWRP soon.
