Notes

The correct method to enter FEL Mode (on some Allwinner devices): Disconnect the device from the charger or USB cable. Press and hold the "Volume Up" button — firmly and continuously. While keeping the volume button pressed, connect the device to the computer using a USB cable. After connecting, press the Power button several short times (3-5 times) without releasing the volume button. Wait a few moments until the computer recognizes the device
