Dahua IPC EASY unbricking / recovery over TFTP

Help?

Thanks, how does one construct the upgrade file for the following, see attached

It's for an empiretech IPC-T5442T-ZE

I successfully flashed:
kernel.img
romfs-x.squashfs.img
partition-x.cramfs.img
firmware-x.squashfs.img

But the problem still persists, no ip and some sort of boot loop.

Must I included additional imgs file besides these?

I'm getting an error anytime I try to write the check.img or sign.img files. Still stuck in boot loop on SD-49225-HN. I have tried a 2018 and 2021 firmware file. I am successfully serving over tftp and writing all the other files but it dies at the end. states in console "0mdo not find BOOT_IMG_NAME!" then "Erasing Update Flag Partition". Any ideas or different files I need?
 
Here is a link:

Make sure you know exactly what to do, or you could end up making a potentially fatal mistake. For example trying to flash a bootloader on a camera that is already booting correctly. If it's not perfectly clear, I wrote some additional details here:
 
Step 2, download this archive which has all the necessary tools (TFTP server, upgrade_info tool, netcat for console log):

To make things simpler I have prepared and tested a package for Eos cameras using my latest modded firmware:

I played with those over 5 years ago! Before selling the camera on eBay.
I think the attached may be what you are looking for.

Thanks @alastairstevenson ! this is already a step forward; do you also have the Dahua_TFTPBackup.zip archive with commands.bat etc? otherwise I cannot perform this update via TFTP since it is looking for that upgrade_info_7db780a713a4.txt file which I do not know how to generate
 
Helo everyone, my first post.

I have a problem with my DVR Dahua nvr5432-16p-4ks2 . I made an update to DH_NVR5XXX-4KS2_MultiLang_V4.002.0000000.6 with didn't worked. ( Certainly i have an English version from China )
My DVR is lopped in rebooting, only a firmware screen is showed and reboted quickly after.

I tried to upload an older firmware to dvr by tftp, and everything seems working but... the problem is that the dvr keep reboot, even when the upload is started (check screen please).

Is there a solution to stop the dvr from rebooting every ~3 minutes ?

Stop bootload. Try enter
wd_disable

If not try use other run template to update short part

Use tftp32 for more quick download

Use printenv 1st or use saveenv to store setting and no need waste time to enter each time params. Just run ...

Try ;)
 
help
printenv


#this enable log
setenv dh_keyboard 0
saveenv

ypu need unpack firmware and put this files near firmware
use short command

run up - is common update
run ... - is part update

you can also use
tftp 0x82000000 filename.ext; flwrite
 
Hello, I am trying to restart a dahua IPC-HFW3441T-Z IP camera by TFTP server with the firmware DH_IPC-HX3XXX-Taurus_MultiLang_PN_Stream3_V3.120.0000000.18.R.230301 downloaded from the dahua site and edited with HxD but I have the error message in tftp Failed.txt window: file not found

I think my commands are wrong, does anyone have an indication of the commands to use? the printenv() does not work.

THANKS.

Used this guide to restore my Dahua IPC HDW5541H-ASE-PV camera. The problem was that when the camera was updated via the Internet, the firmware was incorrect and after that the camera was always rebooting. I used this instruction for recovery and made a video for others, here is the link - . Maybe it will help someone
