I have 4 bricked devices based on HI3516DV300.
NAND flash: MX35LF1GE4AB.
Old partition layout: boot 2MB, kernel 5MB, rootfs 34MB, data 87MB.
Hardware: two IMX327 sensors, LCD display, many other peripherals (wiegand, alarms, usb, mic, speakers, rs485).
U-boot is alive and working over UART0.
The device was originally SIP-AC703, but for years we used it as an IP camera.
The manufacturer has no firmware backups.
I can provide extra info if needed and I'm ready to test.
