You Need to Install the Visual C++ Redistributable Packages.
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?
Somebody has this firmware and upload ??

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:

Power outage during firmware update - Hdw5231rp-z
As my luck would have it, this morning I was in the middle of updating firmware on an older 2MP starlight turret and the power went out a few seconds into the process. The progress bar showed little to no progress when this happened. Now I'm unable to communicate with it; it always times out...
I am trying to upgrade the firmware on an IPC-HDW4431C-A; does anyone know how to get these ZIP files? The links are dead :\ or maybe if someone has them, they could please re-upload them? Thanks!

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

Here you go...
Worked like a charm! (only stupid Windows networking issues to overcome to get TFTP working)
Thanks @alastairstevenson, @Vettester and the OP user!

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 ?
Thanks

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

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
