Dahua IPC EASY unbricking / recovery over TFTP

kuzco said:
I have a successful connection via UART and TFTP, but each "run" commands ends up with an error message: "[ERR0002:]The img header be changed!"

Have compared the BL, and have seen that the old version was:
"U-Boot 2010.06-svn5354 (Jan 31 2018 - 21:02:02)"
now the new has:
U-Boot 2010.06-svn6470 (Dec 11 2018 - 16:27:39)
Click to expand...

While I can't help (yet) what you are dealing with is that newer firmwares past 2019, maybe 2020, are signed. I am told by a reliable source that the partition structure may be changed.

I am in the same position as you. Downgrade attempts (I used serial and tftp to flash each file in the extracted firmware.bin) result in the error you received.

I did not attempt to flash the bootloader, however I now believe this to be necessary. When you flash firmware with the new bootloader I believe it is verifying the signature of some or part of the partition header. So its doubtful to me whether you can downgrade without getting access to the flash chip directly. I don't know (yet) how to disable those checks or if there is some way access to the flash rom from the PCb(s). and not flashing through the existing bootloader. Hopefully I am wrong.

If you succeed please tell!! If I find a way I'll post here.

Good luck

Does anybody know which IPC is running a processor=HI3516CV300 and mem=128M ?
Thanks.

Update: I know that I have the wrong uBoot, so that I do get this error message:
mboot type error, quit upgrade! ImageName=hisi3516cv300-nand, imageName=ssc325-spinand, svn_version=0x2fdb
So again, does anybody know which IPC is running a processor=HI3516CV300 and mem=128M ?

Recovered my IPC-HDBW5231E-ZE!
Saved my day and camera! Trickie thing I needed to pay attention to is to unpack by 7zip the .bin firmware and paste it into /root.
Wireshark is also a very handy tip, off course with an external switch in between and no direct connection.

I just bought a T5442T-ZE from Andy to match another camera I bought last year. It came with an older firmware and needed to upgrade it to match my other camera. Before Wittaj says another OCD case, I don't upgrade unless there is a reason and the reason was the SmartIR and a few other things (which is why I bought the same camera). ;) My other camera is also on the same firmware I wanted to upgrade to.

Camera was defaulted and firmware applied using the web GUI. The webpage eventually timed out and never came back. I went to check the camera and now its on 192.168.1.251 and not accessible. Tried resetting using the button all ways to Sunday (power on, power off, 10 seconds, 30 seconds, 1 minutes, 2 minutes, etc) nothing worked.

Found this thread and I'm getting the following error:

root\failed.txt, File not found or No Access

Even though I'm connecting successfully I tried both direct connect and using a dummy switch no other devices (camera and PC only).

If my understanding is correct, the command.txt file should contain the files listed and in the order of the "Install" file found in the firmware.

Here is the contents of install file from the firmware I got from Andy's site just yesterday (EmpireTech IPC-HX5XXX-Volt_MultiLang_NP_Stream3_V2.840.15OG00D.0.R.220818.bin):

{
"Commands" : [
"burn dhboot.bin.img bootloader",
"burn kernel_min.img kernel_min",
"burn romfs_min-x.squashfs.img romfs_min",
"burn kernel.img kernel",
"burn partition-x.cramfs.img partition",
"burn romfs-x.squashfs.img rootfs",
"burn custom-x.squashfs.img custom",
"burn firmware-x.squashfs.img firmware"
],
"Devices" : [
[ "IPC-HX3XXX", "1.00" ]
],
"Vendor" : "General"
}
/IPC_RestoreDefault

Now there was no custom-x.squashfs.img in the bin file which was strange, I found the thread where Looney posted the same version firmware and compared and it also did not have the custom-x.squashfs.img file. I tried with my commands with both the custom-x.squashfs.img file in there (even though I thought it would fail) and without. It didn't matter.

Since the file didn't exist I did not add it to my latest commands.txt file.

Here is my commands.txt file:
tftp dhboot.bin.img; flwrite
tftp kernel_min.img; flwrite
tftp romfs_min-x.squashfs.img; flwrite

tftp romfs-x.squashfs.img; flwrite

Here is my upgrade_info_7db780a713a4.txt file generated from the commands.bat file:

Here is the output from my TFTPServer.bat command:

I did increase the timeout in the ini file from 60 to 500 but when I ran it again it said timeout was 255 (I guess that is the max). Rerunning again didn't change the result so didn't include that capture (this post will be long enough as is.

Here is the Console.bat output which nothing appeared in until the TFTPServer.bat finished running:

I did have a wireshark running but forgot to save it for the last run. Of course I just realized that as I'm trying to attach it. :banghead: I did capture the first run when I had custom-x.squashfs.img file in the commands. It is attached if that helps. I can run this again and capture it if it will help. I'd do it now but I've spent countless hours trying to fix this and need to get out office before I go insane.

Since my eyes are exhausted looking at this, can anyone see something I am doing wrong or missed? It's still communicating (although on 192.168.1.251 and not 192.168.1.108) so it's not completely dead.

Thanks in advance.

Status update.

After reading the messages again I ended up adding a blank files to root called "failed.txt" and "success.txt" and got further along. I never get the "FLASHING_DONE_STOP_TFTP_NOW" message and it seems to start the process over again. From the console output I see that:

cmd:(sleep 5) is not support!

so I guess it is not waiting the 5 seconds and going right back into the loop.

I also read all the threads again and changed the order of the img files in the command file and removed the dhboot.bin.img from the list.

Here were the last to command files I tried:

Commands attempt 14:
tftp romfs_min-x.squashfs.img; flwrite
tftp romfs-x.squashfs.img; flwrite
tftp kernel_min.img; flwrite
tftp kernel.img; flwrite
tftp partition-x.cramfs.img; flwrite
tftp sign.img; flwrite
tftp check.img; flwrite
tftp .FLASHING_DONE_STOP_TFTP_NOW
sleep 5

Commands attempt 14 console output:
There was an error on the sign.img so removed it for the next attempt (15)

I didn't save the upgrade since it's basically the same as attempt 14 (goes into a loop)

Unfortunately I still don't have a working camera but I think I am getting closer. Hopefully someone has an idea.
 
Hi!

Camera SD6AL245U-HNI-IR PTZ got suddenly into a boot loop.

Whilt TFTP'ing I got in the log:

[SKIP]
erase : 38%
erase : 39%
erase : 39%Skip bad block 0x02bc0000
erase : 40%
erase : 41%
[SKIP]
write : 40%
write : 41%
write : 42%Skip bad block 0x02bc0000
write : 42%
write : 43%
[SKIP]

Does this mean, that camera's storage is dead?

Camera is still in the boot loop.

Hey, everybody.
I got a DH-IPC-HFW4433F-ZSA camera.

изображение_viber_2024-08-12_14-37-21-793.jpg

Received it in a state of not booting.
I managed to download the firmware DH_IPC-HX4XXX-Eos_Chn_PN_Stream3_V2.680.0000000.46.R.231027.bin via tftp.

The camera started up, I can access its web interface (only in Chinese) or configure it via SmartPSS.

I can add the camera to the Dahua recorder (Europe) on the old firmware of the recorder.
I can NOT add a camera to Dahua (Europe) on the new firmware of the recorder 4+....

Is there any broken firmware for this camera, so that it works with Dahua recorders (not Chinese) with firmware version 4+...??

Hey gang!

I have an Amcrest IP8M-T2499EW that seemed to have kicked the bucket after a few months of operating, and I stumbled across this thread hoping to try and salvage it. I was able to get serial comms working and confirmed that the U-boot was working properly, but I am unable to get any ethernet communication to/from the camera. The Amcrest IP scanner (or IP Config) tool didn't work, and no real communications were ever picked up by Wireshark. However, every time the unit powered up, there would be a flurry of Wireshark activity which makes me think it is sending something, but I was never able to ping the unit, nor was I able to ping my computer from the serial console of the camera. To be clear, I had the unit powered on my bench using a lab supply, and then connected directly to the laptop's USB->Ethernet adapter.

As a hail mary, set up the TFTP server as documented in this post, but the camera only ever said something to the effect of "too many attempts" when trying to connect, and the TFTP script/server never indicated it "heard" anything from the camera. I also connected an ethernet tester (one of the Amazon style cheapies) and it seemed to indicate the cabling was OK. Rudimentary multimeter checks (just ohming) didn't indicate any opens or high-resistance on the ethernet isolation transformer's windings.

Any of you folks experienced something similar? Or have any ideas where to go from here?

On my side, i am trying to unbrick my VTH2621.

Looks like the dr, dk, etc... are not set on this device...

Hi, i'm trying to unbrick my VTH5221D intercom internal unit - i've taken all those steps from the first post and nothing moves after i click on TFTPSever.bat (listening on: 192.168.254.254:69 is the last line).
I've plugged the unit directly into my laptop's ethernet and set the IP to:
General:
IP: 192.168.1.1.
Subnet: 255.255.255.0
Advanced:
added IP: 192.168.254.254 and subnet: 255.255.0.0.

Downloaded scripts and unpacked the firmware (image) General_VTH52X1D_Eng_P_SIP_V4.300.0000000.4.R.20190319 to root folder of the downloaded Dahua_TFTPBackup folder. (attached root pic)
Then i'm not sure if i have to change the original commands.txt file? I player around with it and changed it in notepad++ but to no different result. Can somebody let me know what commands exactly do i need to put in, based on my root folder images?

After i saved commands.txt file i ran commands.bat file, tftpserver.bat and consolde.bat. Then i plugged in power cable into the vth unit.

What step did i mess up? Perhaps just the commands.txt file isn't appropriate for my device?

Kindly help.

Thanks!
