Hi all, I recently bought a ELEGOO Conqueror Robot Tank kit that came with a ESP32-S3 camera module, and I am having a lot of problems trying to reflash the stock code back onto it after I tried editing it as per the pdf instructions (the instructions in the code are contrary to what the code itself says, there are two different codes for the camera in one downloaded folder but the large zip file with all the code just has one, etc). In my attempts to reflash the chip, I've installed the EspRFTestTool and the Flash Download Tool as well as ESP-IDF to figure out what is going on.
Trying to upload any Arduino sketch:
Sketch uses 2100651 bytes (66%) of program storage space. Maximum is 3145728 bytes.
Global variables use 53544 bytes (16%) of dynamic memory, leaving 274136 bytes for local variables. Maximum is 327680 bytes.

So basically, esp-idf gives me working flashed code but I want to figure out why I can't upload stuff using esptool and the Arduino IDE. I've done every single troubleshooting step I can think of, I've changed cables, changed computers, disconnected the camera completely from the rest of the tank robot, pressed/held/spammed Boot and Reset buttons, tried different combinations of DIO/QIO and 40mhz and 80mhz for flashing, I'm honestly kind of stuck at this point. Is there something obvious that I'm missing? I will gladly share any additional info if needed. Thanks in advance.
