Repeat each of the above steps for each of the.* VERY IMPORTANT This must be done between each. Close down the entire XTCOM_UTIL program, and unplug the USB.Click on 'Download' and wait for the flashing to complete.bin file to flash, and configure the correct destination address as in the readme.txt file ( For Example: boot_v1.1.bin 0x00000) Hit API TEST -> (4) Flash Image Download in the menu.If you don't, then make sure your connections are correct, and perhaps try swapping the RX and TX pins around. You should receive a notification about success before hitting 20 times. The 'Try to connect times: ' message should increment a few times as the utility tries to contact the module. You should receive a notification saying 'Operation Succeeded!' Configure the settings to whatever COM port you are using, and 9600 baud rate.Power everything by plugging into USB port.bin files to, which I will duplicate here for reference boot_v1.1.bin->0x00000 bin files, an executable named XTCOM_UTIL.exe and also a readme.txt file containing the addresses to flash each of the. Inside the esp_flasher.zip file, you will find a couple of. You will need to unplug and re-plug the USB cable 4 times during the process, so make sure you can reach it easily Flashing the firmware В¶ After all the upgrades have been loaded, it needs to be disconnected) GPIO0 to ground (for the duration of firmware upgrading.If ESP8266 is flashed with Arduino program to access GPIO pins, then the existing firmware of ESP8266 will be completely erased and Arduino code will be uploaded to that module.

If it doesn't work, try swapping them around) Before installing the new firmware into ESP8266, we can check the current firmware version of ESP8266 module by using Arduino IDE serial monitor.

TXD to RX, RXD to TX (this may depend on the USBSerial board you are using.

You need to hookup these pins from the ESP8266 to your USBSerial board:

You can download all the required files in this ZIP file esp_flasher.zipДЄbove is a pin out diagram for the ESP8266 Module This flow provides a tool for managing Over The Air firmware updates for ESP8266 Wifi SoC modules running the Arduino.

If your USBSerial device enumerates to a higher port number than that, you will have to change it via Device Manager in Windows.

The firmware updating software only works on COM ports 1-6.

It allows easy plugging into a breadboard, which then allows me to hookup the pins of the ESP8266 module via jumper wires to the corresponding pins on the USBSerial board.

You will need some form of USB to Serial converter that allows operation at 3.3V.

You will need a Windows PC for this update.

It worked for me, and may work for you, but I take no responsibility if your ESP8266 module stops working after attempting this. Note that this information has been cobbled together from multiple websites and the official Espressif AT Github Repository.
