Hi guys, I am having the same problem (trying to reset the password) on my AVTech KPD674zb-c. I have tried the suggested solution: Disconnected the DVR power. Then, made the chip resistor (TP5 and TP6)short-circuited with a paper clip, and re-connect the power. I then remove the conductive paper clip when I heard a short beep sound, then wait till the DVR reboots, but on each occasion it has made no difference, and I have not been able to reset the password. Could you help me with the instructions for running an update.bat from the command prompt? Thanks! Mziyas
