[HOW TO FLASH] how to flash PULSe 4K

To flash the PULSe 4K (the full-sized version of the Mini), you are using a high-performance HiSilicon-based receiver. Like the Mini, it uses a Recovery Menu system that allows for “Multibooting,” meaning you can install multiple images into different slots.

Preparation

1. USB Drive: Use a USB 2.0 or 3.0 stick formatted to FAT32.

2. Download Image: Ensure you have the firmware specifically for the PULSe 4K (not the Mini).

3. Extract Files: Unzip the archive. You should see a folder named pulse4k.

4. Copy to USB: Place the entire pulse4k folder in the root of the USB drive.

   • Structure: USB Stick -> pulse4k -> (files: imageversion, kernel.bin, rootfs.bin, etc.).

The Flashing Process

1. Power Down: Turn off the receiver using the physical power switch at the rear.

2. Insert USB: Plug the USB stick into the front USB port (behind the flap) or the rear port.

3. Initiate Recovery Mode:

   • Press and hold the Standby/Power button on the front panel.

   • While holding it, flip the rear power switch to ON.

4. Access Menu: * Keep holding the button until the Multiboot/Recovery Menu appears on your TV screen.

   • Use your remote to navigate to “Flash Recovery Image” (for a clean install) or “USB Multiboot Image Upgrade”.

5. Confirm Slot: Select which slot you want to flash the image into (usually Slot 1 for your main image).

6. Wait: The screen will show a progress bar. Do not turn off the power during this process.

7. Complete: Once finished, select “Boot” from the menu or allow it to reboot automatically.

Quick Tips

• Front vs. Rear: While both ports work, the front USB port is generally more reliable for initial bootloader recognition.

• Slot Management: Because this box has 4 slots, you can keep your old stable image in Slot 1 and test new ones in Slot 2.
