2. MicroSD card (minimum 8GB)
3. Firmware file (.img format) compatible with your device model
4. USB cable

Step 4: Power On Device and Enter Recovery Mode

* Continue holding the Volume Down button until the device enters recovery mode (which may take a few seconds).

Step 5: Navigate Recovery Menu

* Use the Volume Up and Down buttons to navigate the recovery menu.

Step 6: Locate Firmware File
