I'm pretty sure that will work to interrupt the bootloader.control-U not supported..
It's the NVR 4.x firmware that you need, the one that has caused the problem.i think software is from 2015 if i remember right.
Is that the actual IP address of the laptop?Somehow it can't find laptop via serial connection..
The tftp server needs the network.Is just serial connection needed or a network too?
Big sigh of relief!Finally got it going.
By default, they will be using the admin password that was originally used on the NVR.Now to get the cameras sorted.
No reason why they'd be bricked.There all non responsive. So bricked I'm assuming too.
That's good - it means you have the correct camera admin password.have gone into one camera so far and changed ip details but of course i cant add it as cameras are not allowed to delete.
We need a bit more detail in order to help -when i use my serial cable in putty to do the control+u thing it just comes up with this in putty
What actual problem are you seeing and what was done to the NVR to cause the problem?i am having the same issue with my ds-7732ni-i4
Hi Sorry for the late reply it happen when i updated the NVR to the latest firmware. it is a USB to Serial Converter off amazonWe need a bit more detail in order to help -
How are you connecting to the NVR?
Is it via a DB9 connector on the back panel, or via a 4-pin connector on the main board?
What type of interface are you using on the PC?
Is it a serial TTL to USB convertor, or an RS232 serial interface?
What port settings have you configured in PuTTY?
They should be baud rate=115,200, 8 bits no parity.
