Troubleshooting
Player Fails to Power On or Charge
Cause: Using a fast charger (exceeding 5V-2A or 30W) can put the player into protection mode, preventing it from powering on or charging.
Solution:
- Charge the player with a standard 5V/1A charger or via a USB cable connected to a computer for at least 20 minutes.
- While still connected to power, press and hold the Volume "+" button and the Power button simultaneously for approximately 10-15 seconds until the screen lights up. This should enter forced recovery mode.
- Use the Volume "-" button to navigate and select "Factory Reset Mode".
- Press the Power button to confirm. The player will restart and return to normal operation.
- For all subsequent charging, always use a 5V/1A charger or a computer's USB port.
Player Cannot Be Powered On After Long-Term Non-Use or Full Battery Drain
Solution: Connect the charger to the device. Do NOT attempt to power it on immediately. Wait until the screen displays the charging indicator and the battery level reaches 5% or above before turning it on. Attempting to power on with insufficient charge may prevent the player from starting.
