ESP32-S3 Hardware ROM Bootloader Recovery Mode

If your device fails to connect, becomes unresponsive (bricked), or repeatedly bootloops after a customized binary update, follow these steps to manually force the ESP32-S3 microcontroller to load its internal hardware ROM bootloader sequence:

1

Hold the Boot Button

Locate the miniature, physical BOOT button built onto the GhostChip board. Press and hold it down firmly.

2

Connect USB Power

While continuing to hold down the BOOT button, plug the USB connector directly into the computer's USB port.

3

Release and Flash

Release the physical BOOT button. The ESP32-S3 is now running in hardware bootloader ROM mode. Click the Connect Device button above to start flashing.
