In most cases this error means, that there is a problem with your phone's flash chip (damaged of write protected).


Also, to connect the phone, try to do the next:

2. Fully charge phone's battery by using external charger.

4. Connect the phone to Box, press "Connect" button in Software and connect battery. Also try to connect with USB cable.
5. Try to connect the phone with different values of JTAG Speed.

Try to connect the device a few times, if the problem is still present, check HW.
