I have read the thread and others quite a few times and haven't seen anything to answer my problem. I admit i am not the best when it comes to doing this kind of stuff that's why i have come to this board hoping someone with knowledge could help me. I would not have got this far without the information from this thread. So if anyone can help please do. Thanks

Sorry, but when I look at your posts, I guess you did not even understand how it is supposed to work.
Your bootloader does not even try to download anything.

I'm not very tech savvy. So do this mean the camera cannot be fixed? Your help and knowledge would be much appreciated

I see. We dont even know what device it is. There is by far too many questions open: cam type, fw you are tryin to flash, pc setup, network setup, ... Your setup is for sure not as it should be.
As I said, pls. read the tread again - I am convinced you did not understand it, sorry.

The issue has been resolved! Thank you for your forum. Helped to install the high version and then return the old one. It's working.

That's a great post, well done and thanks for sharing!
If / when I get a Dahua camera (not convinced I'll get good functionality with Hikvision NVRs) I suspect it will come in very useful.
Dahua have included / retained a lot of useful functionality in their U-boot, unlike Hikvision who strip it to an almost useless state in pursuit of their 'let's make using our products difficult for our knowledgeable customers' stupid strategy.
can you tell me your contact information I need your help ?

Easy recovery without serial: Dahua IPC EASY unbricking / recovery over TFTP

Hello,

I broke my camera by accident while messing with the firmware and had to recover it.
Since I am not the only one that this has happened to and will probably not stay the last one: Here is a simple tutorial on how to unbrick your Dahua IP camera.

Warning: The cameras serial port is 3.3 Volts, do not try to use RS232 which is 12 Volts!!

For this you need:
  • A broken camera with the bootloader still working - assume it is working if you don't know.
    • If you know it is not working, look *here* and don't be afraid to ask
  • A serial UART device, such as:
    • Raspberry Pi or any other microcontroller/devboard with UART
    • USB to serial converter: These can be bought for *very* cheap from china:
    • Connection Settings:
      • Baud Rate: 115200
      • Parity: None
      • Bits: 8
      • Stopbits: 1
      • Flow control: None
      • (CR/LF Auto)
  • Working firmware.bin for your device, use the chinese one if you aren't sure!
  • A TFTP server
    • You should be able to figure this out by using Google.
First of all you have to locate the RX (receive) and TX (transmit) pins on your camera:
On my IPC-HFW4431M camera (and probably all other generation 3/Eos cameras) they can be found very easily:
For other cameras this page on the Dahua wiki should prove useful: ResetIPCamera - Dahua Wiki
On most devices the serial port consists of 4 pins/pinheads which are made up of VCC,GND,RX,TX.
You can connect the GND (Ground, -) of your dongle to the metal casing of your camera.
VCC (+) should not be connected.

You can identify the TX (transmit) pin of your camera by connecting it (press wire against pin) with the RX pin of your serial device.
Though be aware that some dongles swap the labels like so:
Dongle says RX, but it is actually TX of the dongle and wants to be connected with RX of the other device.
If you power up your camera and see text scrolling down your terminal you have found the right pin, keep trying if you don't ^^

Now put a brick on your * key with your terminal window in focus.
Try to find the RX (receive) pin of the camera and connect it with the TX pin of your dongle.
Power up the camera, wait a second, if you see the following message you have succeeded:

Use setenv to adjust the network settings:
  • ipaddr -> The IP address of the camera
    • setenv ipaddr 192.168.1.108
  • gatewayip -> The IP address of your networks gateway (router)
    • setenv gatewayip 192.168.1.1
  • netmask -> The netmask/subnet of your network
    • setenv netmask 255.255.255.0
  • servip -> The IP address of your computer (that runs the TFTP server)
    • setenv serverip 192.168.1.4
You can test the connection to your PC by runing ping $serverip
Code:
> ping $serverip
ETH0: PHY(phyaddr=-1, rmii) link UP: DUPLEX=FULL : SPEED=100M
MAC:   00-12-34-56-78-91
Using gmac device
host 192.168.1.4 is alive
(Okay actually I don't even know if Windows will reply to pings by default - so I guess you can ignore this for now)

Extract the firmware image for your camera somewhere, use some ZIP program like 7zip. It might complain about invalid ZIP file (since Dahua changes the ZIP header from PK to DH) you can either fix the ZIP with a HEX editor or use another program to unzip it.

Start the TFTP server and point it to the files you have extracted from the firmware image.

And now for the final part: Flashing the firmware!
I'll flash following partitions in order:
  • romfs (root linux filesystem with busybox)
  • kernel (The holy Linux Kernel)
  • user (Dahuas programs and kernel modules)
  • web (Webinterface)
  • partition ("Partition table" - text files which describe the layout on the flash chip)
  • custom (Language files)
Do not flash the bootloader! There is no need to and when you fuck that up recovering is a lot harder.

Run following commands one after eachother:
Code:
run dr
run dk
run du
run dw
run dp
run dc

Example output:
Code:
> run dr

You can run save if you want to save the environment variables you have set (ipaddr, servip, ..).

Run boot to boot the camera :)
Congratulations!
(If you just read this for fun and do not have a bricked camera I still suggest you to buy a serial UART dongle, they're cheaper than most snacks and you can save lots of devices with it!)
(If this helped you and you have some spare for a student: paypal.me/BotoX)
I have a broken camera ,and I fogot where I place , so I use a good hdw4433c-a to test , but when connected with serial port , it displays more information , how I interrupt it . as follows:

Привет родимые!
Проблема с DVR Dahua DHI-NVR2104-S2 2016 года выпуска.
Во время загрузки висит на Логотип Dahua затем через 2 минуты уходит в перезагрузку и так постоянно.
Подключение к USB-TTL, и вот что он мне дал:

Никаких проблем нет с этим уже давно, читай форум и инструкции по восстановлению или сбросу конфигов.
Остановить загрузку
Дальше
setenv dh_keyboard 0
saveenv
reset
Увидишь причину падения и работу watchdog
А дальше помодульное восстановление или через update.img, специальный файл.
Прошивки все доступны, как и русскоязычные форумы, а то тут админы и некоторые начнут ворчать, что ты бы еще на клингонском бы написал и т.п., .. ;)

Thanks friend! Tell me at least what topics to read to restore it?
