7608ni-i2/8p firmware problems now loop booting

[ctyson21]

Hi All

I have upgrade to the latest firmware due to the cameras making the NVR reboot but now have another problem with the NVR constantly rebooting in a loop.

Is there a way to roll back the firmware to an older version?

I have seen the 4.51.006 firmware is meant to be better but i can get the TFTP to install the firmware as i think they wont let me downgrade it.

Any help would be appreciated

thanks

Ok so i have now managed to downgrade to 4.501 from 4.61.030 as it caused the above problem

Even though Hikvision's Tftp was saying it had successfully transferred the file it hadn't and it would just start up and do it again, i have since learned this was because the new firmware is over the size limit that program can transfer.

I found this on whirlpool forum and thought i might share it here as other people must be running into the same problem and think they have bricked there NVR as i got pretty close to buying another one!!

First set your computer IP address to 192.0.0.128
Then start the Tftpd64 server first(from here http://tftpd32.jounin.net/tftpd32_download.html). This locks the TFTP transfer port on the PC so that the Hikvision one can't use it.
Next start the Hikvision TFTP server which authenticates the NVR on the undocumented port. The 3rd party TFTP server takes over for the TFTP session as it has exclusive use of the common TFTP port.
I put the digicap.dav file in its own directory and in Tftpd64 browsed to that directory, make sure Server interfaces is on the 192.0.0.128 option in the drop down list
Now turn on your NVR
I had to keep the Hikvision TFTP Server running throughout the whole transfer, and then once the transfer was complete shut the both down.

It restarted and is now running!!!

Dick and AndyO-Perth, you are a bloody legends. Thanks for taking the time to post it on your forum.

Cheers

Yes, the Hikvision tftp updater tool has a 32MB filesize limit.

Another option to get around that size limitation is to use Scott Lamb's Python2 clone of the tftp updater, from here :
