Download the combined.bin file- B. Connect the development board to the computer through a reliable Type-C cable, then click the BOOT button, and then click Reset- C. You can open ESP Web Flasher【Web flashing is convenient! Manual likes!!! ], click serial port connect, select update bin firmware file, program to burn firmware Install, Repair, or Update UF2 Bootloader Latest version: 0.16.0 The UF2 bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. If a UF2 bootloader is installed, you can check its version by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FTHRS2BOOT, MAGTAGBOOT, HOUSEBOOT, etc.) It is not necessary to reinstall a UF2 bootloader unless a BOOT drive is not visible when in UF2 bootloader mode, or you know of a problem with your current UF2 bootloader. If a UF2 bootloader has never been installed on the board, or the UF2 bootloader was removed by erasing or overwriting the flash, the UF2 bootloader must be installed in order to flash .uf2 files onto the board. .bin files can be uploaded without a UF2 bootloader, using the [ESP Web Flasher](https://adafruit.github.io/Adafruit_WebSerial_ESPTool/) or esptool.py. Note: update.uf2 files are not currently working on ESP32-S2 or ESP32-S3 boards. Important: this will erase previously flashed firmware and sketches from the board, but needs to be perfomed only once. The instructions here are general. We recommend you consult the manufacturer's board documentation for detailed instructions, which may be different. Unzip to find the file combined.bin. Place board in bootloader mode:Plug board into a USB port on your computer using a data/sync cable. Make sure it is the only board plugged in, and that a charge-only cable is not being used.Press and hold down the BOOT or 0 button.Press and release the RESET or RST button.Release the BOOT button. Upload combined.bin (Google Chrome 89 or newer):Open [ESP Web Flasher](https://adafruit.github.io/Adafruit_WebSerial_ESPTool/) in a new window/tab.Select 460800 Baud from the pull-down menu (top-right).Click Connect (top-right).Select the COM or Serial port from the pop-up window.After successful connection, click Erase.After successful erase, click any Choose a file..., then locate and select the combined.bin file unzipped earlier.After successfully choosing combined.bin click Program.After the TinyUF2 firmware update is complete, press the RESET button on the board. A new drive BOOT should be visible in your file browser. After installing the UF2 bootloader, enter the bootloader by double-clicking the reset button. On boards with an RGB status LED, tap reset once, wait for the LED to turn purple, and tap again before the purple goes away. On other boards, consult the board documentation. After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated.Then you will need to load or reload CircuitPython using the .uf2 file. Source: [https://circuitpython.org/board/adafruit_feather_esp32s3_tft/](https://circuitpython.org/board/adafruit_feather_esp32s3_tft/) - On boards with Adafruit factory firmware, you can follow the steps below to flash the CiruitPython firmware. #Flashing ciruitpython UF2 firmware - Download the prepared firmware UF2 file: adafruit-circuitpython-adafruit_feather_esp32s3_tft-en_GB-8.2.3.uf2 - Connect the USB Type-C data cable to the computer, double-click the RST button, and [FTTRS3BOOT] will appear in My Computer - Note: After clicking RST for the first time, when the LED turns purple, click the RST button again until the LED turns solid green. <ignore_js_op> <img style="cursor:pointer;" id="aimg_725415" aid="725415" src="/bbs/static/image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '0')" zoomfile="//bbs.eeworld.com.cn/data/attachment/forum/202308/21/112623fsdj5nqjigjgspq4.png" file="//bbs.eeworld.com.cn/data/attachment/forum/202308/21/112623fsdj5nqjigjgspq4.png" inpost="1" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" /> <div class="tip tip_4 aimg_tip" id="aimg_725415_menu" style="position: absolute;

The OP is so lucky to get the goods. We are all going to the end of November and we may forget about it by then.
