⚡️ Flashing the Fydetab Duo

Here is a step-by-step guide for flashing a new OS onto your Fydetab Duo.

Getting Started

Before you begin, make sure your device is ready and that you have all the necessary tools at hand. We will guide you through the process of entering Loader Mode, checking the device status, and flashing the new OS image.

Step 1: Prepare Your Device

1. Ensure the device is powered off
   Before connecting your Fydetab Duo to your computer, make sure it has been shut down completely.

2. Connect your Fydetab Duo to your computer
   Use a USB Type-C cable to connect the device to the computer you'll use for the OS flash.

   note

   Due to an oversight by our factory supplier, the Type-C cable that comes with the Fydetab Duo doesn’t support data transfer. Please use a different Type-C cable that can handle data transfers.

Step 2: Enter Loader/Maskrom Mode

Follow these steps to enter Loader Mode, or Maskrom Mode if necessary:

1. Hold the Volume Up button (vol+)
   Press and hold the vol+ button on your device.

2. Press the Power button briefly
   While holding the vol+ button, press the power button for 0.5 to 1 second.

3. Release both buttons simultaneously
   This should put the device into Loader Mode.

   tip

   If releasing the buttons simultaneously does not work, try releasing the power button first, followed by the vol+ button.

4. (Windows Only) Switch to Maskrom Mode
   Use the RockdevTool to switch to Maskrom Mode if necessary (see the Windows section below for details).
   
   

Step 3: Check the Status

Once the device is in Loader Mode, your computer should be able to detect it. The screen will display an image indicating that the device is in Loader Mode.

note

On devices with first-generation firmware, the LED will remain off, and the screen will stay completely dark. This is normal.

Step 3: Flash the image
