ONEPLUS ONE stuck in setup after unlocking / enable USB debugging with broken screen

Hey, I'm currently on the Oneplus One and have never had problems with it. A few weeks ago however, i dropped it with flipcase from 30 cm not really hard or something, no physical damage visible. But at first the touchscreen didn't respond at all and after rebooting, everything worked except for a 2 cm stripe of the lower touchscreen + capacitive buttons.

So i wanted to root it and find options to workaround this issue. But in order to do that, I needed to unlock it and delete all of the userdata + settings, so basically a factory reset. (see android-hilfe (Dot) de/thema/how-to-oneplus-one-rootanleitung-unlock-recovery-rootvorgang-von-a-z.596012/ )

Now I'm pretty much stuck in the cyanogenmod setup (set language etc.) where I can't the option 'Next' due to the broken touchscreen in the lower section (see drive.google (Dot) com/file/d/0BwIC1YNaC4EMTEdOaHYycU15T0U/view?usp=sharing )
It's really a stupid reason why I can't continue and because of that, I can't enable USB Debugging and, of course, adb. Fastboot is enabled, TWRP is installed. Any way to bypass the setup or enable USB debugging from the PC (that wouldn't really solve the CM setup issue though)

Thanks for the help!
