Hikvision - Clearing Passwords and/or Loading Firmware via TTL Serial

You may be needing to use a null modem cable if it's really RS232 as opposed to TTL serial..
If feasible, try swapping pins 2 & 3 on one of the DB9 connectors.

I ran by the nearest shop and got a null modem, that did the trick. Thanks

Excellent!
It seems you have pretty good shops down your way.

Thank you this worked for me. Saved my DS-KV6113-WPE1 from continuing reboot after selecting Semi-Digital mode.
Now I have also a new one since I had not seen your method before ordering a new one.
New one has a new firmware that I cannot find on any server( V2.1.3 build 191113). The old one is V2.1.3 build 191015 and has an infra red malfunction possibly because of firmware
Is there any way to export existing new firmware and save as file by using putty or telnet and tftp server?

Thank you

If the serial console can provide root shell access to the running system - files can be extracted.
But I'd expect that root shell access will be blocked.
Sometimes also the bootloader (if there is one in the device) has flash memory commands.
 
Thanks for the tips in the original post, they helped a lot.

Posting below in case it helps someone else:

I had updated my DS-7616NI-I2/16P NVR with firmware which corrupted the user DB so instead of showing 'admin' it showed a list of users with square unicode looking characters, and my password was no longer accepted.

I could not get the TFTP server (tried both 32 bit and 64 bit versions) to upload firmware so I tried the ttl-serial method in this post. I connected fine but couldn't interrupt the bootloader process (i.e ctrl+u had no effect).

Cutting a week long story short, I ended up re-trying with the NVR and my PC connected to a network switch with IP address set on my PC accordingly, but not using the serial connection. Then using Solarwinds tftp server (and the correct firmware of course), it worked immediately. The new firmware transferred straight onto the NVR, it rebooted and was then as good as new.

Good Morning,

Can someone give me some input. I have a DS-7608NI-E2. I updated the firmware last week and not the login user names are a bunch of squares and the password doesn't work. I think I'm pretty close, PuTTY just can't seem to complete the download.

I'm plugged in trough the serial port. The NVR is plugged into the my swtich and another cat5 plugged in from one of the nr camera ports into my laptop.

It's timing out, possibly because the tftp server / updater is not reachable on the network.
I'm guessing that the IP addresses you have specified may not be correct.

You should specify for the 'device' a valid IP address for your LAN. Maybe what the NVR normally uses.
And for the 'upgrade server' specify the IP address of the PC running the tftp server / updater.

oh I thought I attached a screenshot. I’m using the 192.0.0.64 for the IP address and 192.0.0.128 for the server like in the all instructions. A bunch of T’s fill the screen “T T T T T T... retry count exceeds. Starting again” and then it’ll just keep repeating that process.
 
alastairstevenson said:
Is that what you have set the PC IP address to?
If so - the Windows firewall may be blocking access to the tftp updater. Try disabling it temporarily.
Normally you'd not need to change that, just use the normal PC IP address.

Thanks for the input alastairstevenson.

Yea, I set the IP to the same address.

I turned off the firewalls and nothing changed:

There is a networking problem.
Are both devices wired to a switch or router?

Why don't you just use the normal IP addresses on your network?
No need to match what the usual tftp updater process would use.

Maybe also try a normal tftp server such as the 32 bit one from jounin.net
 
Ok I figured out what was

I figured out what was wrong. I had the cat5 from the laptop plugged into the back of the nvr (because that what I was used to). I unplugged it and plugged it into the same switch. Not it completes the process reboot and goes back the upgrade prompt. I this because I have the wrong firmware version? I dowloaded v 3.1.0 from the US site. Which one is the newest one I can use or should I use for my DS-7608NI-E2?

The rollback block disallows installation of firmware versions older than the newest that has been attempted, whether it was successful or not.
Another of Hikvision's ways to show how they respect their customers.

Do you know what version was previously loaded?
Ideally that should be the first to try.

There is a good selection here :

DOWNLOAD EU PORTAL

No, what I meant and maybe didn't say it clearly was that the first firmware to try reloading would be the same one that had been already loaded.
Don't just jump to trying newer versions as that makes the rollback block even worse.

The file that I have just says v3. I'm pretty sure I got it from the US site last week (the site says v3.4.96, I'm pretty sure its that one). I take it I should try v3.4.96 from the EU Portal first, hoping that works or v.3.4.97 since it stops at v3.4.98? It's not possible to load an older firmware?

This all started because I needed to reset my password. When I called in to Hikvision after the corrupted firmware update, they said I should've moved from one firmware to the next one progressively and not skip. Is that true?
 
Hello,
I have one DVR DS-7216HQHI-K1/A . I want to default all the configuration but I can't do it from software, monitor or IE.

I want to upgrade it via serial.

I had tried with command "update", after reboot nothings change.
