The TAPS are located under the battery, behind the Huawei phone label. The phone will be powered by a Micro USB cord from an AC battery charger.
The TAPS order is as follows:

For the TAPs, the Huawei-8650 was utilized, pictured above. The TAPS on the M865C are located in the same location as the 8650. See below for TAPS locations.
After the wires are connected to the board, the phone is powered by the USB connection. Plug the Micro USB into the USB connection on the device and then plug the phone into a wall outlet. The phone should respond with the vibrator switch activating for less than a second.
Launch the Riff Box JTAG Manager and use the following settings:
