Hello.

The problem can be with powering the device. Try to do the next:

1. Reboot PC.
2. Carefully check soldering of each JTAG wire again, solder them as short as possible (max. 3-5 CM length).
3. To power the device please use BOTH - fully charged battery (or external power supply) AND USB cable.
4. Also try to connect the device with different JTAG speed values. Try to connect a few times.
5. Post the result.
