I spent the last two weeks getting to know everything about these cameras and this thread will capture all this information. It will take me several weeks to document all the information so please be patient.

There are a variety of problems that I will try my best to explain and share the possible solutions. I have gotten pretty comfortable with these cameras and have purposely bricked them to various degrees of severity just to validate the recovery process. Most people “brick” their cameras trying to upgrade the firmware. This is not a serious issue and it can be corrected very easily. The camera runs an upgrade service on port 3800. The configTool always shows a default port of 37777 but this is not an issue as it can do the upgrade on port 3800 anyway. Change your port to 3800 and use a firmware file lsted below and you are back in business.

I will keep updating this post as I get more time to write all the details around recovery. I will also post links to over 40+ firmware files that and which cameras they will work with. It will take me a bit of time to capture all this information, so please be patient.

 How to Download and Prepare Firmware

This guide will show how to download and prepare the firmware file for a Dahua device.

Firmware files for Dahua devices can be found at Firmware by Device or the specific product page for the device

Firmware is typical provided in a ZIP file, a compressed file format

This file will contain the actual firmware file, which needs to be extracted from the ZIP file in preparation for the upgrade

Unbricking your Dahua IP camera (Tips, Tricks & Firmware)

BRICKED CAMERA? How can you tell?

There are several types of “BRICKED” camera conditions and they have varying levels of severity and also varying levels of complexity for recovery. Most are simple and caused by bad firmware uploads. The worst will require a full rebuild of the partitions which load the kernel, software and all other data.

1. The first step in identifying the severity of your issue is to determine what still working on your camera. In order to do that, lets remove as many variables as possible to the troubleshooting process. If possible, connect the camera ethernet and PC ethernet on it’s own switch and make sure that no vlan tagging is enabled on the switch.

Next, you need to figure out if the IP address is still reacheable. Ping the last known ip address. The default address for most cameras is 192.168.1.108.

If you don’t know it you can use the arp/ping method to configure which adds as startic arp entry to a new ip address. (This feature is enabled on the camera by default)

2. Once you have a pingable IP, you need to know what services are still active on the camera. This can be done with a simple port scanner. I have added a link to below in tools.

3. Run the port scanner and record which ports are still open. In many cases port 23 and port 3800 will still be open. If this is your situation, it is a very simple fix. If no ports are open, you will need to do a full image load which is more complex.

The typical ports that you would see are:

23 – Telnet access

80 – Web User interface

443 – SSL

554 – Real time streaming port

3800 – Upgrade Deamon

5000 – UPnP

37777 – TCP Video streaming

37778 – UDP Video Streaming

42323 – Real time remote runner

Plus a whole bunch more of UDP ports and more TCP ports

REPAIR WITH PORT 3800

Download a step by step guide (DAHUA IP Camera Recovery v1.0.pdf) with screen prints @ http://tinyurl.com/lbl3up7

1A. If port 3800 is open you can connect with the Dahua Config tool (link below in tools). I tdefault to port 37777 but change it to 3800 as this port where the upgrade daemon is listening. Port 37777 is a redirect but it won’t work if your firmware has failed.

Launch the config tool and click on login button. Type the IP address , username and password then port 3800.

Open a know working firmware file and upload to the camera.

1B. If port 3800 is not open, go to the next step to enable port 3800.

2. If you have telnet access, you can login with putty. Link to putty below in tools. The default Web UI password is admin / admin.

In older firmware the telnet account is root / vizxv

In newer firmware the telnet account is admin / 7ujMko0+”web UI password” —> 7ujmko0admin

Once connected you can execute a ps command to see running processes. /usr/sbin/upgraded process is what listens on port 3800 for the firmware binary file.

There is also another copy in /var/tmp/

A useful tip for watching the upgrade process is to kill the “upgraded” process that is running and re-launch it in the foreground to watch the upgrade.

Here you can see each partition being loaded wit the individual img files. I will write a quick how to on loading each one individually at a later time.

If you chose a valid firmware file, you will be back in working order. If you still have problems, repeat with another firmware file till you have a valid file. The IPC-HFW4300S-V2 is not natively compatible with all other 4300S firmware. I am in the process of writing a how to that explains how to over come this issue.

UNBRICK WITH UBOOT via SERIAL

NOTE: This section is coming soon… I’m gathering all the images I need for various camera types

OTHER USEFUL INFORMATION (to be sorted later)

The firmware consists of several images that are loaded into various partitions in flash in a UBI file system. You can load each partition separately if needed. More on this later…. (I’ll put a guide together on flashing and recovering partitions)

Once you telnet into the camera, there are number of useful binaries in the user shell that can help correct and diagnose some of the problems people are experiencing. One of the helpful steps is to kill the /var/tmp/upgraded process and run it in the foreground so you can see what is going on and easily capture error messaged. The /var/tmp/upgraded process is what opens the port 3800 and allows you to connect to the camera with the config tool if your web services have failed. There is also another copy in usr/sbin/.

Also, in there is a command to reset all the parameters back to factory defaults (username, password, ip address back to 192.168.1.108 etc.) This can be accomplished with /sbin/clearparam.

Another issue that people run into is the constant reboot issue. This can be caused by a failed process. The main application which provides all the camera capabilities (web interface, streaming, etc.) is /usr/bin/sonia. This process is what makes most firmware different from version to version (sort of). There are also changes to the web partition which contains the web server pages that /usr/bin sonia hosts on port 80. The sonia process is invoked by a shell script in init.d and if the process is killed, the camera reboots after a few minutes. This has cause many people issues when trying to “unbrick” the camera since you only have a few minutes between reboots.

To stop the reboots you can update the flash. There is a parameter called appauto that tells the camera to auto start /us/bin/sonia. If you want the camera to start and not invoke the shell script that launches sonia, you need to set appauto to 0. This will stop the camera from rebooting when sonia is not running.

This cam be accomplished by running ‘/sbin/appauto 0’. To turn it back on, just run /sbin/appauto 1. This writes the boot parameter in flash that the kernel reads before starting the process. You can check the current status of the appauto bootparameter with ‘cat /proc/dahua/bootpara’ It will only show what the parameter was when you booted up, so if you changes it you need to reboot to see the change in /proc/dahua/bootpara.

Realtime streaming URL – rtsp://192.168.1.108/cam/realmonitor?channel=1&subtype=0&proto=Onvif

You can change the subtype to 1 for the secondary stream also you can add user:password@ in front of the IP address if you have the permissions set requiring it.

You can use the HTTP API to configure some parameters that are not yet in the web UI. For instance, another member discovered he could enable NFS through the web UI in addition to the local SD card. This config is not possible through the web interface as you need to pick one or the other.

These documents details the API of Dahua video products (links provided to some of the versions below). Programmers or users can access and configure Dahua video products through the API. Every setting of the camera is available through the API whereas only a small number are available through the WEB interface. The document with version 1.10 is available with firmware version 2.0 and above. This document with version 1.20, 1.21, 1.22, 1.23,1.24,1,25,1,26,1,27,1,28 is available with firmware 2.210 and above.This document with version 1. 29 ,1.30, 1.31, 1.32, 1.33, 1.34, 1.35,

1.36 is available with firmware 2.210 and above.This document with version 1.37 is available with firmware 2.212, 2.4 and above.

I have also done a bit of testing around the tftp process that is invoked in u-boot that looks for upgrade_info_7db780a713a4.txt and failed.txt. I think with a little more work, I’ll figure out if there is a recovery method using tftp without serial access. This would be necessary if you lose telnet access and need to rebuild the kernel partition that hosts telnetd.

I will also post the bare metal img files when I get some time which contain the firmware and all the img files including the update.img that can be used for serial recovery.

I have just started the process of uploading firmware… There are much more to come as well as many more camera models.

Also if you have any you want to share please PM me what you have and where I can link them to this thread.

Thanks to Euly for sharing firmware files!

IMPORTANT NOTE FOR IPC-HFW4300S-V2 CAMERAS

The new camera appears to have differences (a few that I already found) that makes some of the general firmware incompatible with them. I have found a workaround, but it is complex. I will try to summarize it in a separate thread in the following weeks. I will also repackage the newest firmware files in versions that will work for the V2 cameras. Stay tuned! In the meantime, you can use General_IPC-HX5(4)XXX_Eng_N_V2.210.0000.21.R.20140613.bin or the PAL equivalent to recover your camera.

Well, that’s all I have time to share for now, but I’ll do my best to put together a comprehensive guide to the inner workings of these cameras and a guide to unbrick in any failed software situation.

Thanks and take care.

DDNS stands for Dynamic Domain Name System. The main advantage for DDNS is If you have a dynamic ip address, (where your address can change monthly by your ISP if not static) the DDNS service will track and update with your new IP address automatically. So no matter what your numeric IP address is, your DDNS address will work even if your numeric IP address changes.

Prerequisites

• The device must be connected to the Internet, please check if the connection works properly.

• Please confirm Internet access port is open and default port to open is: 80, 554,37777. To modify default port, please refer to DDNS User’s Manual.

• The default username and password are admin/admin. You should change your password at first login.

• DDNS management website: www.DahuaDDNS.com
