Gentleman,
I’m looking for some help with my Dahua VTH2421FB indoor monitor. Unfortunately, a wrong firmware was flashed, and now the device is bricked and no longer boots.
I have already tried to recover it via the serial interface (TTL). However, I’ve hit a wall: I can see the boot log (showing the version, chip type, and some basic info), but I cannot get a command prompt or a "stop autoboot" sequence to work. It seems the bootloader is either locked or corrupted to a point where it doesn't accept input.
Does anyone happen to have a full dump firmware for the VTH2421FB? I am prepared to flash the chip directly using an EEPROM programmer (Xgecu t48), but I lack the correct image file
