[HOW TO FLASH] how to flash AX MULTIBOX Twin

The AX Multibox Twin is a versatile 4K receiver powered by a HiSilicon chipset. Because it is a “Multibox,” it is designed specifically for multibooting, allowing you to have different images (like OpenATV, OpenHDF, etc.) stored in different internal slots.

Step 1: USB Preparation

• Format: The USB drive must be formatted to FAT32. (HiSilicon boxes are notoriously picky; a small USB 2.0 drive is often the most reliable).

• Folder Structure: When you unzip your image (e.g., OpenATV 7.x), you will see a folder named ax.

• Target Path: Inside the ax folder, there must be a subfolder named multiboxtwin.

  • Path check: USB_DRIVE:\ax\multiboxtwin\

  • Crucial Files: You should see appcfg.bin, boot.img, fastboot.bin, kernel.bin, recovery.img, and rootfs.tar.bz2.

Step 2: The Flashing Procedure

1. Power Down: Turn off the AX Multibox Twin using the physical power switch at the back.

2. Insert USB: Plug the drive into the side USB port.

3. Boot & Trigger:

   • Switch the rear power toggle to ON.

   • Immediately press and hold the Power Button on the front panel (or the Reset button depending on your hardware revision).

   • Once the front display shows “UPDT” or “Flsh,” release the button.

4. Wait for Progress: The receiver will begin the flash. You can monitor the progress on your TV screen via HDMI. This usually takes 3–5 minutes.

5. Reboot: Once the process is finished, the box will automatically reboot into the Setup Wizard. Remove the USB drive during the reboot.
