As far as I know, nobody's figured out how to use the TFTP setup to unbrick a Dahua camera. Their tech support people can do it, but nobody's had much luck getting anything out of them either.
Be sure to keep us posted on your progress!
Yo! Check it out! If it becomes well documented, and it works, this guy's a hero...
Yes this method works. With some difficulty, but I also restored my dead camera IPC HFW2100.
The myth about the invincibility of the DAHUA destroyed!!!
