Loader can get unpacking file firmware
dhboot.bin
dhboot-min.bin
DH_IPC-HX4XXX-Eos_Eng_P_Stream3_V2.420.0000.22.R.20161209.bin

But how to reflash? With briked dump i have only ping. No open ports. I scanned with port scanner. No telnet/ssh. How to compile this bins to flashing to SPI?

how would you like to use the image of spi flash?
wanted to use the programmer?
you have already received the data from the chip 25Q128, send me, I'll see what happened with the bootloader.

Loader is healthy
you can connect a console program and a ttl usb adapter
and restore the ip camera
follow the thread on the forum Dahua IPC unbricking / recovery over serial UART and TFTP
I looked at the firmware that is available in your image and can assert...
This ip camera Chinese, for the domestic market. you need to use the appropriate firmware from the Chinese website update.
