[HOW TO FLASH] how to flash Protek 9900 LX

To flash the Protek 9900 LX, the process remains consistent with the LX series, utilizing a Broadcom-based bootloader. Success depends entirely on the correct folder hierarchy on your USB drive.

Preparation

1. USB Drive: Use a USB 2.0 stick (ideally 8GB or smaller) formatted to FAT32.

2. Download Image: Ensure the firmware is specifically for the Protek 9900 LX.

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 stick.

   • Structure: USB Stick -> protek -> 9900lx -> (image files: 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 rear USB port.

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

4. Initiate Flash:

   • Watch the front panel display.

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

5. Wait: The display will show “Flashing” or “Loading”. Do not interrupt the power during this time.

6. Complete: The box will reboot automatically. When the setup wizard appears on your TV, the flash is successful.

Quick Troubleshooting

• Folder Name: Double-check that the subfolder is exactly 9900lx. If the files are loose in the protek folder, the box will not find them.

• Automatic Flash (Force): If the front button is unresponsive, open the 9900lx folder on your USB, find the file noforce, and rename it to force. This will automate the process upon startup.

• USB Pickiness: Older Broadcom receivers are notoriously picky about USB sticks. If the box boots to its old image, try an older, slower USB 2.0 drive.
