Thanks for your answer Pav,

i have already done these steps but for me it doesn't work.
i have done all the steps one more time and i have taken some pics :

the Hantek software is at latest version :




The driver Dfu is installated :




But there is a mistake when i run autoupdater; nothing happens ! only the same text again and again.

I press and hold F1, but the lower right corner (play / pause) light never flash.

the only light that flash is the power button when i plug usb

i have tried many time, one time no pressing F1, one time pressing and hold F1 and pressing and hold on/off button, ... but it's always the same result.




i have read on this forum that when update firmware fail, the device is brick, do you think it could be that ?

I have tested twice, with the batteries, in this case the power button stay always on. Without the batteries, the power button is blinking. In the two case, with the hantek soft or with the dfu, the isddvice doesn't appear. When i try to force an rescue update with the hantek soft it display the device is connected with no end, and nothing else, nothing happen.
