ESP32-CAM (ESP32-S) connectivity issue

[Lemandros]

Hello,

I recently bought 2 ESP32-CAMs. One of them seems to be broken. I have attempted to run the camera web server example from Arduino, as well as attempted to flash a custom version of micropython with a camera package. I am using an FT232RL to connect to my computers. Identical steps, different outcomes. One of the 2 flashes to micropython correctly, and I have gotten it to work just fine with multiple cameras. The other, however, returns a timeout error during the upload of firmware. Dependent on the baud rate, the upload stops around 3-5% (always on 0x00005000) and times out. See my attached screenshot. In Arduino, I can see the various console prints it performs when connecting in normal mode or in flashing mode. It doesn't print any garbled characters there, so clearly it is functioning up to a point.
Does this seem fixable, or is it a hardware issue? Thank you in advance!

It might be broken. One other potential explanation for that screen is that you hit the reset button when the ESP32 was already being written to.

Are there any software tools for deeper diagnosis? I definitely did not press the reset button during the upload.
