Firmware dump for Hi3516ev200 8M SPI + IMX307 sensor

[nh1980ro]

Hi,

Please help me with a dump of the SPI for IPCAM HI3516EV200 with IMX307 sensor (1080P/ 2MP Sony), SD card and WiFi.
I connected the camera through UART to my desktop.
I can write OpenIPC on it, but I would like to put back the 'original' firmware, because it was easier to use.

I remember that the original firmware had version: V20.1.23.6.x_2019.... but I can try to write on it any firmware dump that was built for HI3516ev200 with IMX307. Maybe it works...
I am planning to write only the SPI image from 0x40000 to 0x800000 (without U-Boot), so I do not brick it for good.

The details of my camera SPI are:

SPI Nor(cs 0) ID: 0x20 0x70 0x17
Block:64KB Chip:8MB Name:"XM25QH64AHIG"

Oh, I forgot to mention, that I do not have the original firmware dump, because first I managed to brick the camera when I tried to update it through some firmware update tool, via ETH, and only then I bought a UARTtoUSB stick and 'wired' the camera's port.
