## Flashing
|
|
|
|
To flash ESP32-S3 devices like the T-Watch, you typically need to place them in Espressif's firmware download mode. Use the "1200bps reset" button in the web flasher to do this. If this method does not work for any reason, you can follow the manual process below.
|
|
|
|
:::warning
|
|
|
|
Do not proceed unless an antenna is connected to avoid possible damage to the device's radio.
|
|
|
|
:::
|
|
|
|
The following process will manually place the device into the Espressif Firmware Download mode:
|
|
|
|
1. Ensure the device is powered off by pressing and holding the crown button.
|
|
2. Remove the device's back cover.
|
|
3. Locate and press and hold the boot button.
|
|
|
|
|
|
|
|
4. While holding the boot button, press the crown button once to turn the device on.
|
|
5. After 2-3 seconds, release the BOOT button.
|
|
|
|
With the device now in the Espressif Firmware Download mode, you can proceed with flashing using one of the supported flashing methods. It's generally recommended to use the [Web Flasher](https://flasher.meshtastic.org/). You can select "T Watch S3" from the device drop-down.
