When I enabled USB debugging in settings for Zopo ZP300+, an unrecognized device appeared in device manager: H9000+.
Then I followed this: https://web.archive.org/web/20160918125953/http://www.zopomobileshop.com:80/zopo-rom/how-to-install-driver-for-zopo-mobile-phone-step-by-step-instruction/. MT65XX Preloader replaced with "MediaTek PreLoader USB VCOM Port (COM3)", then it disappeared. I unplugged the USB, turned on the phone, and plugged it back in. No new drivers were installed. H9000+ is still unrecognized. Eclipse says: No compatible targets were found.
