    Dahua IPC EASY unbricking / recovery over TFTP

    That I cannot help with..... if it is a China market device than yes a very good possibility English firmware will not work. I have no idea on what might as I do not have one of those. I would assume the Dahua Config Tool, you should have this as it gives quick confirmation if a device is active...

    Dahua IPC EASY unbricking / recovery over TFTP

    That seems like a normal way for it to finish. Leave the device powered. Once it gets to that point you can exit the dos windows so it does not try to do the same process all over again. Wait for up to 5 minutes as the device will be loading the new firmware and re-starting on its own. After a...

    Dahua IPC EASY unbricking / recovery over TFTP

    Hard telling why it is failing without a serial console connection. You can always try not using the single file update.img method. That would mean update the commands.txt file, run the commands.bat which updates the other file. Then put the appropriate individual firmware img files in the root...

    Dahua IPC EASY unbricking / recovery over TFTP

    If it accepted the update.img file than it might be installing the firmware. It does take a few minutes to load it all.

    Dahua IPC EASY unbricking / recovery over TFTP

    Correct.... the .108 ip will only be active for a few seconds. Unless it finds the TFTP server, gets the file and starts downloading the firmware in which case it will be active for a bit longer. One critical element for this easy method is that your neworking must be configured correctly so...

    Dahua IPC EASY unbricking / recovery over TFTP

    I have no idea of a VTO has an actual connector..... every other Dahua camera I have looked at does not. They all have the row of 4 holes on the board that you see beside the led toward the upper edge of the board. That is the serial connection. You have to either get a set of leads with little...

    Dahua IPC EASY unbricking / recovery over TFTP

    I would try it this way myself. I'm not familiar with the tftp the pd-x file as no device I have uses a command like that and I do not have a VTO camera. I do not know that the run dd command is or does. I'd remove it. run dc run dr run du run dw run dk run dt run pd tftp 0x82000000...

    Dahua IPC EASY unbricking / recovery over TFTP

    Run up would be used only if you have an update.img file. If you do have that then you do not need to use any of the others as update.img internally contains all of the other files. There will also be some files when a firmware is extracted that are not needed or used in this method like the...

    Dahua IPC EASY unbricking / recovery over TFTP

    I also posted this similarly in the other thread.... You are getting two very different methods confused here. 1 - there is the method of using a TTL serial cable and connecting to a device. This is where you manually type in commands at the devices boot prompt in a console window. That method...

    Dahua IPC unbricking / recovery over serial UART and TFTP

    You only use the run commands for the files your particular firmware has. There are other commands because some devices have different files. Remove the run commands for any files you do not have as well as the pd-x.cramfs line. One special one is if you have a update.img file than use ONLY that...

    Dahua IPC EASY unbricking / recovery over TFTP

    Okay using the method you started with. After you update the commands.txt file you are then also running the commands.bat file too right? That is required to update the upgrade_info_7db780a713a4.txt file. It does look like in the short time that it is indeed finding the TFTP server (your...

    Dahua IPC EASY unbricking / recovery over TFTP

    Ah - actually I just realized this. The "commands" file update method is using a network connection. With a direct serial connection you need to use a terminal program like Putty and just type the commands directly into the console which is a totally different method of accessing and updating a...

    Help identifying model/firmware

    Since Impath Networks appears to be gone you have no way to get firmware from them. If you can find a correct firmware file for the camera you would extract it and potentially determine exactly what it is and what the correct newer firmware might be for it. As old as the firmware is, there is a...

    Dahua IPC EASY unbricking / recovery over TFTP

    It looks like you only have 2 pins connected on the serial connection when you need 3. There should be a ground pin, a TX (transmit) pin, and a RX (receive) pin. If you have an update.img file for the device then use that. Your commands.txt file should be run up tftp 0x82000000...

    Help unbricking a Dahua NVR with TFTP and serial connection.

    Yes - that is exactly what it will do. Tested it too on mine. :) I have no idea why they configure it with the pins swapped but my guess is they have some sort of programming system that they use in the factory that needs it.

    Help unbricking a Dahua NVR with TFTP and serial connection.

    Forgot to update... it was exactly as I thought it would be. Just disconnect the serial connector on the board inside. With the flat side of the connector facing you as shown in the photos, you just need to swap the middle and right wires. You can see the little tab that sticks up which retains...

    Starvis versus non-starvis CMOS

    I think it is not so much as directly which one is considered better. It is more which one is considered better for a particular use.

    If it never reaches the cloud then you configured something on your router/firewall to block it from making the outgoing connection to the Amazon AWS servers.

    Review-Dahua IPC-A46 4mp indoor PT cam.

    The common thread for "cloud" and IoT (internet of things) devices goes across many products like home automation stuff as well. Start looking for a HA controller that is 100% locally run with its own built in web server and you will find that your choices are slim but "cloud" connected and...

    Help unbricking a Dahua NVR with TFTP and serial connection.

    I work with a lot of industrial equipment as well as networking hardware that almost all have serial console access for things and it just seems that true hardware USB ports always seem to be far more reliable than software driver emulated ports. So I've always used a Dell Precision pro...

    Review-Dahua IPC-A46 4mp indoor PT cam.

    On the one I have I have been unable to get my NVR-5216-4KS2 NVR to display the A46. SmartPSS picks it up just fine. I also have loaded the new firmware on the A46 so I do not have any web access to it. I tried the method to put the web UI back on it from another thread and it bricked it but I...

    Dahua IPC unbricking / recovery over serial UART and TFTP

    On all firmware since from what I read, sometime in 2016 or 2017, the firmware is signed. You would need to decompress the archive, easy, then make your changes, then decompress the file, then generate a new CRC checksum, than use the CRC checksum along with a 2048 bit key to sign the file. This...

    Help unbricking a Dahua NVR with TFTP and serial connection.

    I know on mine, last years model 5216-4KS2 you MUST use a null-modem serial cable. It is just a regular cable, no TTL adapter. My computer does have a real serial port as well which might help. I've had problems using some of the USB add on ones in the past for stuff like this. I used the Dahua...

    Dahua DHI-NVR4208-8P - how to downgrade firmware

    I think once you change to signed firmware you cannot revert to old unsigned firmware (which also has a LOT of security bugs, backdoors, etc). New does too but at least most are fixed. I think you might be able to manually do it using a serial cable though.

    Help me to prevent buying Reolink... Source for Lorex in Europe

    Depending on the Lorex kit you get you can also cross flash the NVR to Dahua firmware, at least for some models anyways. Found another thread on that here the other day and it was the same one I got. Did it on the one I bought and it worked great and enabled more features. Kinda tricky and had...

    Dahua IPC EASY unbricking / recovery over TFTP

    I used this yesterday to work on another model camera and learned a few things. The Commands.txt file for one. I was changing it with notepad and that kept putting a space or something at the very end. Whenever you change Commands.txt you then need to run Commands.bat. Commands.bat generates a...
