Dahua IPC EASY unbricking / recovery over TFTP

I have a problem in my sd59225u-hni after installing all the firmware with this method I can't install the ptz part
 
Goodmorning everyone,
I am desperate.
They hacked my nvr dahua.
I found the password reset tool and entered another password, the problem is that the serial number has become 000000000000000000 !!!
Now I can't log in to the cloud anymore.
Help.
 
Thanks. Used the tools and guide (after some modifications) to unbrick my QSEE NVR. Basically you setup the FTP server on your computer and extract the firmware .img files in there. Use the Commands.bat file to create the .txt file that the NVR is looking for to run commands and when the NVR boots it will look for your FTP server and file and run the commands. You can also find the file it is looking for if you console in with a null modem cable. For the NVR I removed all other commands and left just the TFTP part and was able to transfer the file firmware. Rebooted and everything is working now. Pretty simple process after understanding what it is doing.


Again, Thanks!

So I tried to convert my Amcrest IP8M-T2499EW to Dahua IPC-HDW4831EM-ASE
I used firmware DH_IPC-HX4XXX-Eos_EngFraSpaRus_PN_Stream3_V2.420.0000.22.R.20161209.zip


This was what I got after 1st attempt:
Client 192.168.1.251:1425 root\failed.txt, File not found or No Access

I logged into camera web interface and reset to "Factory defaults"
After reboot I got this:

All subsequent attempts ended up with this:

And I can no longer log into web interface
Bricked it.
 
Good afternoon, I'm trying to revive a vto2111d-wp. I wanted to update the firmware using Conftool (then I realized that I had to do it through VDP).
The update failed and the computer did not start anymore.
I read all the forum pages and I can't make it work,
Try the Duvel method, TheDude comments ...
The only thing I get is
starting TFTP ...

Getting the hang of it
Try reset VDP many time & possible request from vdp will catched by PC.
I saw many trouble situation when fry use this way.
Find TTL2USB adatper.

Good afternoon, buy the USB ttl, I already have it connected, and what it throws on the console is:

What are the modules that I should install? sorry so many questions but now that I have console management I would not want to break it
 
Working !!!!! Run line by line from the console and lift perfectly.

run dw
run dp
run dc
tftp 0x82000000 .FLASHING_DONE_STOP_TFTP_NOW
sleep 5

I enclose images in case anyone needs:
red cable pin 1 rx from pcb to tx from usb ttl
yellow pin 2 tx cable from pcb to usb ttl rx
black gnd cable

All thanks to iTuneDVR, thank you very much, greetings from Argentina!
