In this comprehensive tutorial, we will guide you through the process of flashing the E9 Pro miner using an SD card. This tutorial is specifically tailored for Windows users. By following these steps, you will be able to upgrade your E9 Pro firmware to mine either ETC or ETHW. Please ensure you select the firmware that aligns with your mining preferences.

Tools Needed

To proceed with the flashing process, make sure you have the following tools ready:

  1. Hardware: Computer (with a Windows operating system), TF card reader, and a TF card.
  2. Software: Decompression tool (we recommend WINRAR) and the E9 Pro card flash firmware.

Steps to flash your E9 Pro

Step 1: Downloading the Firmware To begin, download the appropriate E9 Pro card flash firmware for your desired mining coin from the provided link: [Insert hyperlink to the firmware download page]

Step 2: Creating the TF Card

  1. Unzip the downloaded firmware file by right-clicking on it and selecting “Unzip File” using your decompression tool (e.g., WINRAR).
  2. A dialog box will appear after the file is unzipped. Click “Confirm” to proceed.
  3. Once unzipped, you will see a folder with the same name as the zip package. This folder contains the necessary files for flashing the E9 Pro miner.
  4. Insert the TF Card and Format it
  5. Insert the TF card into the card reader and connect the card reader to a USB port on your computer.
  6. Your computer will detect the new device and assign it a disk letter corresponding to the TF card.
  7. Format the TF card to the FAT32 file system by locating the disk corresponding to the TF card, right-clicking on it, and selecting “Format.”
  8. In the formatting dialog box, choose FAT32 as the file system and click “Start” to initiate the formatting process.
    • Note: Formatting will erase all data on the TF card. If you have important data, back it up before proceeding.
  9. Copying Files to the TF Card
  10. Open the folder containing the unzipped files from Step 2.
  11. Select all the files inside the folder and copy them.
  12. Paste the copied files into the root directory of the TF card.
  13. Verifying TF Card Contents Before proceeding with the flashing process, confirm that the TF card contains the correct files. Verify the file names, sizes, and number of files.
  14. Flashing the E9 Pro Miner
  15. Power off the mining machine by disconnecting all power cables.
  16. Insert the TF card that has been prepared into the miner.
  17. Power on the mining machine by reconnecting all power cables.
  18. Monitoring the Flashing Process
  19. After powering on, observe the indicator lights on the miner.
    • The double-light network port light should remain steady.
    • The double light will turn off, and after approximately 50 seconds, the green light will remain steady.
    • Once the green light remains steady, the flashing process is complete.
  20. Completing the Process
  21. Power off the mining machine and carefully remove the TF card. Press the card inward, and it will partially pop out, allowing you to remove it safely.
  22. After removing the TF card, power on the control board and boot up the miner.
  23. Log in to the miner’s background interface to verify if the firmware version matches the card-swiped firmware.
