Hi,
I recently tried to upgrade the dvr model mentioned to the firmware version 4.21 mentioned here, but now I ended up with a dead/bricked one. It does start, the HDD starts, the fan starts, the red led on the main board is on, but no beep and no lan or serial connection shows up.
I tried to use TFTP, by configuring the the computer ip to 192.0.0.128 and starting the TFTP app, but there is no ethernet / lan connection between the DVR and the computer and the TFTP app says 127.0.0.1 initialized.
I also tried to use a USB-Serial adapter, but either I did not know the pin configuration or I can't explain but there was no output in putty when using the serial connection. Can you recommend a good serial to usb adapter ?
Do you have any advice on this issue? Is there anything else I can do, or is it completely bricked?
Thanks!
