Hello, I have an old DVR which I tried to upgrade to the latest firmware. Profound Meditation Program 3.0 Review. I requested the firmware for my device from a representative of the company and it was sent to me via email. I unzipped the file, copied it on a USB stick and flash it on my DVR through it's interface.
By downloading the firmware from this web page you are agreeing to Hikvision's Software User License Agreeement. DVR with firmware v3.1.15 or higher. Mar 09, 2017 Please i need link for my upgrade firmware DVR Hikvision DS-7204HVI-S. I have v2.2 build 091202 firmware version Thanks for your help. CCTVBrands Supports posted this on May 24, 2016. To upgrade the firmware of a Hikvision DVR/NVR, first download the appropriate firmware.
The process completed successfully and the DVR rebooted. Since then DVR is in a constant boot loop. I tried unplugging the cameras, booting it up without the hdd installed, removing the battery from the main board so that it will reset to factory settings, used a power supply from a friend that has a working DVR but nothing worked. I went from a functional device to a device I can no longer use. Please find the link to the firmware provided as well as a short video I made that illustrates the exact process of the boot loop. Firmware: Video: PS: please lower your audio level while watching the video because the dvr speaker beeps very loud.
Boot loops are built into the firmware and can be triggered by many things - you'd only be able to know what by connecting to the serial console of the DVR. Common on the newer NVRs are trying to put EN firmware on a CN device, for example. This is the 'official' firmware - which may well be the same as that which your seller supplied - same rev and build date, not sure about the language though. It may be worth trying it with the tftp updater. *edit* But here is some older firmware that the readme.txt suggests would fit your model - may be worth trying.
Thank you for your reply. The 'official' firmware is the same as the one I flashed on the device, including language (verified with hiktools- EN/ML).
I tried the tftp updater but it did not work, it only showed 'TFTP server initialize' ( I did change the computer IP to 192.0.0.128 and connected it directly to the ethernet port on the device). I read on the forums that the TFTP update utility has some issues with windows 10 and unfortunately the computer I tried it on has windows 10, as well as all the other computers that I have available. I will give it a shot with the older firmware, see if that is of any help. I am not sure how I can connect to the serial console of the DVR but I am willing to give it a try if you can help me with some advice. I do not know if I have a CN device and not sure how I can find this out but the odds of it being CN are small, in my opinion, since the device was bought from a local retailer in my country (Romania, Europe) At the moment I am also awaiting a response from hikvision support regarding this issue. I will post here if I receive any helpful answer.
