Generally China Phones are flashing through two types of communication

1. COM 2. USB

1. COM port communicate with Rx (Receive), Tx (Transmit) lines

2. USB communicate with D- . D+, data lines

DP = Data Plus = D+
DM = Data Minus = D-



Some Phones like Speadtrum , Mstar , AnyKa , latest MTK based phones etc.. flashing via USB Port.

Now a days almost all china flashing boxes are support both pin finds. USB faster than COM
