[HOW TO FLASH] how to flash Protek 4K X2

To flash the Protek 4K X2, you are working with a Broadcom-based 4K receiver. The process is very straightforward, provided you use the correct folder naming convention, which is the most common pitfall for this specific model.

Preparation

1. USB Drive: Use a high-quality USB 2.0 or 3.0 stick (8GB or less is recommended) formatted to FAT32.

2. Download Image: Get the latest firmware (OpenATV, OpenHDF, etc.) specifically for the Protek 4K X2.

3. Extract Files: Unzip the file on your PC. You will see a folder named protek.

4. Copy to USB: Transfer the entire protek folder to the root of the USB drive.

   • Structure: USB Stick -> protek -> 4kx2 -> (image files: kernel.bin, rootfs.bin, etc.).

The Flashing Process

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

2. Insert USB: Plug the USB stick into one of the USB ports (the side port is often faster to recognize during boot).

3. Power On: Flip the rear power switch to ON.

4. Initiate Flash: * Watch the front panel LED or the TV screen.

   • When you see the prompt “Update?” or “Press Power”, press the Standby/Power button on the front panel immediately.

5. Wait: The LED will blink or the screen will show a progress bar. Do not turn off the power until the box finishes and reboots itself.

6. Complete: Once the setup wizard appears, you can safely remove the USB stick.

Quick Tips for Protek 4K X2

• Folder Name Check: Ensure the subfolder inside protek is exactly 4kx2. If it is renamed or missing, the bootloader will skip the update.

• The “Force” Method: If you find it difficult to time the button press, open the 4kx2 folder on your USB, find the file noforce, and rename it to force. The receiver will then flash automatically upon power-up.

• USB Selection: If the box boots normally to the old image, try a different USB port or a different USB stick brand.
