Hello, i have bricked HDBW4431R-Z. Bootloader crash. Havent any open ports. Only ping. I flashed directly flash 25q128 with dump from another camera: HDBW4431M-I2, now camera working but both cameras use same MAC address, and in HDBW4431R-Z lose zoon/focus function.
Do you have backup dump from this camera? HDBW4431R-Z
