Nobody will make a rom for this device. My device arrived with K1.0.7 rom which doesn't have google play. Pandawill uploaded V1.0.0 rom with Google play bundled and 1.0.7 rom without google play and chinese bloatware.
So far your choices are very limited.
I recommend ThL T5 instead of Newman K1B for similar price. Don't get fooled by mtk6589m quadcore cpu.
