4. Firmware Installation and Update

4.1 Preparation for Installing Bixbit Firmware

Install the latest version of WhatsMinerTool. Using outdated versions may cause issues during firmware installation.

• Download the BiXBiT Firmware archive and extract its contents into a separate folder
• Check the control board model and the version (release date) of the currently installed firmware. This can be done using WhatsMinerTool:
  
  or by viewing it in the Status → Overview tab in the ASIC web interface:
  
• To install the firmware, select the appropriate option depending on the control board model (CB) and the current factory firmware version:

Important:
The firmware installation method, as well as the firmware files selected during installation, are determined by the control board model and the current firmware version, not by the miner model itself.

Installing firmware via an SD card completely resets all device settings, deletes logs, and removes traces of custom firmware. This allows you to resolve issues caused by incorrectly installed firmware or incorrect user settings.

Recommendation before sending a device for warranty service:
If custom firmware was installed on the device, be sure to reinstall the factory firmware via an SD card. This will remove all traces of third-party software and reduce the risk of warranty service denial. The use of custom firmware is an official ground for refusing warranty repairs.

4.2.1. Procedure for Control Boards H3, H6, or H6OS with Firmware Versions before 2025

Launch WhatsMinerTool and set the scanning range to include the IP address of the device on which the firmware will be installed. Start the scan and make sure the device appears in the list.

• Step 1: Click [Upgrade].
• Step 2: Click [Select File].
• Step 3: In the pop-up window, select the file Whatsminer-ALL-Models_X.X.X.X.bin from the archive you previously downloaded and extracted (X.X.X.X is the firmware version).
• Step 4: Confirm the file selection by clicking [Open].
• Step 5: Check the box to the left of the IP address of the device whose firmware you want to update. You can select multiple devices if they have compatible control board models and firmware versions.
• Step 6: Click [Start Upgrade] to begin the update process. In the dialog box that appears, click [OK].
  If the update is successful, the Status column next to the device’s IP address will display “Success”. The device will then reboot automatically. After the reboot, open the device’s web interface. If the installation was successful, you will see changes in the interface.

4.2.2. Procedure for Control Boards H3, H6, or H6OS with Firmware Version 2025 and later

If the device has a control board H3, H6, or H6OS with firmware version 2025, before installing the BiXBiT firmware, you must first install an older factory firmware version (prior to 2025). The steps are as follows:

• Stage 1. Preparation for Installation:
  1. Step 1: Go to WhatsMiner Firmware Download, under the "SD-card flashing program" section, select the section corresponding to the control board model installed on your device, download the firmware archive, and extract its contents into a separate folder.
     
  2. Step 2: Prepare an SD card: It is recommended to use an SD card with a capacity of 2–16 GB. Fully format the SD card using the default FAT32 file system (detailed instructions for manual SD card formatting are described in Section 4.3, “Formatting the SD Card”).
  3. Step 3: Using the PhoenixCard program (the program folder is included in the firmware archive), write the “.img” image of the downloaded factory firmware to the SD card (detailed instructions for writing a firmware image to an SD card are described in Section 4.3.2).
• Stage 2. Flashing the ASIC with the Factory Firmware via SD Card:
  1. Step 1: Before inserting the SD card, disconnect the power cable and wait until all indicators stop blinking completely.
  2. Step 2: Insert the SD card and reconnect the power cable.
  3. Step 3: After the flashing process is complete, only the green indicator will be lit. Wait a few seconds, then disconnect the power cable again.
  4. Step 4: Ensure all indicators are completely off, then remove the SD card.
  5. Step 5: Reconnect the power supply.
• Stage 3. Installing the BiXBiT Firmware:
  After rolling back the factory firmware to an older version, launch WhatsMinerTool, set the scanning range to include the IP address of the device for firmware installation, start the scan, and ensure the device appears in the list.
  1. Step 1: Click [Upgrade].
  2. Step 2: Click [Select File].
  3. Step 3: In the pop-up window, select the file “Whatsminer-ALL-Models_X.X.X.X.bin” from the archive you previously downloaded and extracted (X.X.X.X is the firmware version).
  4. Step 4: Confirm the file selection by clicking [Open].
  5. Step 5: Check the box to the left of the IP address of the device whose firmware you want to update. You can select multiple devices if they have compatible control board models and firmware versions corresponding to this section.
  6. Step 6: Click [Start Upgrade] to start the update process. In the dialog box that appears, click [OK]. When the Status column next to the device shows Success, the update has been completed successfully. The device will then reboot automatically. After the reboot, open the device’s web interface. If the installation was successful, you will notice changes in the web interface.
