## Flashing Factory Image You can flash [factory images](https://github.com/skot/ESP-Miner/releases) to your Bitaxe using generic ESP32 flashing tools such as the [esptool-js website](https://espressif.github.io/esptool-js/) - Power up your bitaxe via the barrel connector - attach your bitaxe USB to your computer - open of the [esptool-js website](https://espressif.github.io/esptool-js/) in Chrome - Under the `Program` heading set the baudrate to 921600 (this should be the default) - click Connect - Chrome will popup a window asking you which serial port you weant to connect to. - on Mac and Linux the correct serial port will have something similar to `usbmodem1434401` in the name - on PC it will prolly be one of those COM ports. Good luck. - Select the proper serial port and then click connect - Once the ESP Tool has connected to your Bitaxe over serial, Set the Flash Address to `0x0` - Under File click "Choose File" and select the [factory image](https://github.com/skot/ESP-Miner/releases) you want to flash. it's called something like `esp-miner-factory-400-v2.1.5d.bin` Be sure to use the image with the same version number as your Bitaxe (400 in this case) - Down below click the "Program" button - Wait paitiently. - Keep waiting until the console on ESP Tool says "Leaving..." - If you are _sure_ you have seen ESP Tool say "Leaving..." then you're bitaxe might restart. - If you bitaxe hasn't restarted, you can press the RESET button on the bitaxe - The self test should run. this can take a second. You'll need to press the RESET button on the bitaxe once the self test has passed.
