I have a DVR, I don't know the brand but here is the data:
Hardware Version: 302.6.2.Q13-1.3
MCU Version: 10.04.23
Kernel Version: 1106161434-1003311806-
Firmware: 3.1.81.P-1.0.4.2-06
Lauch Date: 2011-05-21
The default HTTP Port is 8000 and I changed it to 5454 because my ISP blocked that port.
But it starts buzzing and won't boot up.
Please help me solve this problem.
