To be expected when it's not listed in NVR4XXX-4KS2

I think the idea is that you develop / extend and contribute the mod-kit config files as the firmware develops.
As originally posted by @cor35vet :
Code: 
from .config import *

DAHUA_FILES = OrderedDict([
    ("Install.lua", {
        "required": True,
        "type": DAHUA_TYPE.Plain
    }),
    ("u-boot.bin.img", {
        "required": True,
        "type": DAHUA_TYPE.Plain,
        "size": 0x00300000
    }),
    ("uImage.img", {
        "required": True,
        "type": DAHUA_TYPE.Plain,

    }),
    ("romfs-x.squashfs.img", {
        "required": True,
        "type": DAHUA_TYPE.uImage | DAHUA_TYPE.SquashFS,

    }),
    ("logo-x.squashfs.img", {
        "required": True,

    })

Even when you are success in modifying the firmware, there is no way to install it on the device. Latest firmware checks its folder by the checksum, and overall, the sign.img. So if you want to modify any file, you have to make a checksum again for that folder, and sign the firmware. As @cor35vet, it's impossible task.

However, if you have uart dongle, then it's a easy task to upgrade firmware :)

Need help after FW update on a VTH1550chw2

Hello friends,

After trying to flash a knew fw-update to my vth1550chw2 it remains with a black screen.

I the configtool the ip of the device vt1550chw2 is not lister anymore.

I guess I have to connect the device now with com or tftp..
The chw2 model is 2 wire model which receives power and data through these to wires only.

The device on the backside seems to be on because there are some led lights going on and off.

Does anyone has an idea how to get the old FW back on to the device?

Thank you very much!

cor35vet - After overcoming my fear of bricking them, I upgraded a small bunch of 4431M and 4431R-Z cameras from the 21R version to your 22R firmware. 100% success on the first try! As a career software person I think I have a feel for the talent, time, and effort that went into this, and want to pass on a big THANK YOU for doing such a good job and making it available. The upgrade has given me two main things: (1) All the 4431 cameras play nice with the NVR now, and (2) I don't have to play games any more switching versions of the web components (which are "hugely" different between the 21R and 22R versions). Since you're a student, I'm assuming your age and can say that you remind me of myself 50 years ago in the age of the IBM 1620, PDP-8, PDP-10, etc. What you're learning from this effort is likely more valuable than anything from the classroom.

Not sure why do you want to upgrade firmware for a camera which has already supported multiple languages. From the link of seller, I believe the camera firmware is newer than the one in first post.

Is it possible to disable auto focus with this firmware hack? Having issues with LPR and focus creeping at night.
 
hello i have a ip cam brand as IPC c35
Is it a good idea to view the http API through unpacking the firmware? Which partition should I look for for cgi-bin?
Thanks
 
Bought 6 IPC-HDW4233C-A cameras. Four of them came with the firmware in English (and able to select between French, Russian and Spanish). The last two were from another vendor because they had the different lens sizes I needed; but they came with the firmware in Chinese, with no other options to change to. Is there anyway to extract the firmware from one of the multilanguage ones to update the firmware in the last two which show in Chinese?

They all show the same info:

Multilanguage ones:
Device TypeIPC-HDW4233C-A-V2
System Version2.622.0000000.6.R, Build Date: 2017-10-17
WEB Version3.2.1.506361
ONVIF Version16.12(V2.4.0.485616)

Chinese ones:
设备类型IPC-HDW4233C-A-V2
系统版本2.622.0000000.6.R, Build Date: 2017-10-17
WEB版本3.2.1.506361
ONVIF版本16.12(V2.4.0.485616)

Hallo, after installing linux system Ubuntu in a virtualbox, I got the script running. Was my first time using linux and commands out of my dreambox.

So I have one question: Is it possible to extract the firmware of a dahua indoor station VTH1510CH or 1550CH. I want to change the language of the buttons. I tried to decrypt with VTO2000A but it doesn't work correct...I can't open the decryptet files an a lot of error messages.
 
Hello Cor35vet,
Can you mod this firmware? Is for the DH-NVR4208
DH_NVR4xxx_Chn_P_V3.205.0000000.0.R.171013.bin

Thanks!
