Thank you SO MUCH Alastair!! I am up and running... I think it was Hyperterm that didnt show the boot process - so switching to Putty helped. I guess when I couldnt ping the NVR I was doubly confused. Only with a serial comms and Putty the NVR was able to set up the Ethernet link when upgrading...

upon starting tftpserver the boot window stopped complaining about being unable to find it.I attachec the putty terminal screen Does it mean the NVR sees the tftpserver on the PC now ? Do I need the ethernet cable for upgrading or will everything go through the serial cable ?

@alastairstevenson I managed to get into the boot phase. Here is what I see (attached). In order not to mess things up - what is the best way forward. I did not have tftpserver running at the time when I got this screen. I still cant ping the NVR (192.0.0.64) from my PC. Should I just copy...

thanks. do you happen to have the pin-out of the serial connection on the board. my cable I have is red, black (GND), white (RXD) and green (TXD). On the board is yellow (CD1) , red (CD3), black (RD1) , orange (CD2) and brown. which pins should I use ?

oh - hope dies last.. One thing I noticed: when the NVR starts all POE ports light up briefly and it keeps cycling on/off. I.e. after a couple minutes it reboots itself. So some brains atill maybe left .. Hyperterm says its connected but there is nothing showing up in the console and it does not...

Thank you Alastair. I am afraid I am done for good. I ran step 7 from these instructions posted here: http://www.hikvision.msk.ru/_fr/2/How_to_upgrade_.pdf >> Step7: for some reasons, sometimes the DVR can not load the system and go to menu interface, so this step is necessary. Input “f” then...

Hi Alastair I have been able to connect using the serial cable. Now I just need the right firmware.. I tried this...

Hello Alastair thank you for your help. yes - it is beeping 15 times. But I get no message from the NVR in TFTP server (just the first line - see attachment). I have installed : http://oversea-download.hikvision.com/uploadfile/Firmware/NVR/E series/NVR_K41_BL_ML_STD_V3.4.92_170228.zip Before...

Hi I have bricked my NVR... Its a DS-7716N/16P . It boots now with constant beeps (maybe 10-15 beeps) and then reboots. I have downloaded TFTP tool from Hikvision. But it it cannot connect to the NVR. I can ping the address of it (192.0.0.64) but in TFTP it never sees it. I have tried turning...
