Hi,

I'm try'ing to restore an image from vth1550 using this instructions:

Dahua IPC EASY unbricking / recovery over TFTP

A successor of Dahua IPC unbricking / recovery over serial UART and TFTP I recommend you to read through the above thread first. If your camera still has a working bootloader (assume it does) then you can flash it easily, because: The camera tries to download a file called...
ipcamtalk.com ipcamtalk.com

In tftp server shows in a loop:

Nov 10 00:25:57 calvin in.tftpd[1298227]: Client ::ffff:192.168.1.108 finished upgrade_info_7db780a713a4.txt

Nov 10 00:29:14 calvin in.tftpd[1299548]: Client ::ffff:192.168.1.108 finished user-x.cramfs.img

and in a network capture, I can see it failing because a non existing file:

00:36:12.598013 IP 192.168.1.108.3280 > 192.168.254.254.69: 48 RRQ "web-x.cramfs.img" octet timeout 5 blksize 1468

In my firmware I don't have web-x.cramfs.img...

I only have this:

-rw-r--r--. 1 root root 176192 nov 10 00:25 data-x.cramfs.img
-rw-r--r--. 1 root root 260304 nov 10 00:25 dm365_ubl_boot_16M.bin.img

I already try'ed others, but non with web-x. Can someone help me, point me an direction?

Best Regards,

If someone can help.....
 
Off course, a VTH does not have a web server on it, so web-x.cramfs.img is defintely wrong.
How does you commands.txt look like and what's the software image you want to flash on your VTH?
 
Command file must contain only needed filenames.
In order not to guess what is happening, connect to the console and everything will be easier there.
Need full log start from your device.
 
if you need full 16mb image it exist for our version General_VTH151X_Eng_SIP_V4.300.0000000.8.R.20190316

Click to expand...

I've an image for VTH that have web-x.cramfs.img... but can be a wrong image...

Right now I've this commands.txt:

run dr
run du
run dd
run dk
tftp 0x82000000 pd-x.cramfs.img; flwrite
tftp 0x82000000 .FLASHING_DONE_STOP_TFTP_NOW
sleep 5

And finish successfully, but the vth doesn't show anything...

with this commands.txt i wrote the:

romfs-x.cramfs.img
user-x.cramfs.img
data-x.cramfs.img
kernel-x.cramfs.img
pd-x.cramfs.img

The only image (in bin file) that I don't wrote is : gui-x.cramfs.img I don't know how to pass the commands.txt to wrote that....

Thank you very much,

In a vth device, can you send me a link how I can connect to console? I only find to VTO...

Try to get Console.log - either via ncat or via UART.
It's hard to figure out what went wrong if you do not have the log.
