I want to upgrade my tablet to android lollipop. I can't seen to find a rom that can fit my model (wing-inet). So I want to know if you could just update it with any rom.
Simple answer: you cant do that.
Detalied answer: every rom is created for specific device, it contains all drivers etc required for device to work. If you use rom from other device, in best scenario it simply won't work, in worst it will brick your device.
