Troubleshooting Hantek 2D72


Customer Consultation

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.

Será necessário atualizar a memória flash para que ele possa fazer o boot novamente.

The pcb board of this model 2d72 not the same as previous models. (2d42 and others)
I need the location of the points on the pcb of this model where rx, tx and gnd are located so that I can reinstall the flash memory.
To then use the UART interface and then use the ARM1 software.
I tested the procedure sent by Amy, but it did not work and the led remains red and the unit does not turn on.
