I went to update the firmware to the new version htx2021090901. And now it no longer works and does not connect the USB port. Only the red light on the on key is blinking. What procedure should I do? Is there any technical assistance here in Brazil that works with the brand?
Please refer to the video to operate(use the power adapter to supply power, press F1 and hold on, and press power button), and check whether the indicator light in the lower right corner flashes red and green.
