1. the best way is to take the device apart and compare the board design 
with others;
2. the label on board, though format unknown, seems to be different between 
different models and identical for one model;
3. read board-id from stock Android firmware. It's not reliable because a 
board-id might be shared by multiple models. Note this board-id has no other usage because the manufacturer reused a board-id defined by qcom.

We extract some special fields from the label(i.e. ufi001c or uf896) to be 
the model name for a device, currently it's enough to distinguish between 
different boards. 
For example, the label on ufi001c is 'UFI001C_MB_V01', we extract the first field to be the model name.
