figured by writing the wetek play 2 img.gz on the stick instead of the box version. what i suspect is that the box thought that the sdcard contains the exact same system, why would i boot from sdcard. but that doesn't sound very real.. anyway this way i could boot from sdcard, could wget the correct img file, and could run emmctool w libreelec11.img.gz and it's all good now. thanks for your hard work keep it up!
