Update the firmware of Hantek2D72/2D42/2C72/2C42

Sebastien

The firmware update procedure is not working for me.

Pushing F1 + Power. Waiting for the play/pause button to flash.
Asfter that I plug the USB cable.
The power button is red. Play/Stop button is doing a color sequence and after that the scope is starting automatically...
One of my friend have the same scope and when we do the exact same thing it's working on his model.
Not on mine.

Any Idea?

My model  is 2D72
Serial : CN19010072001385

why is that a 30-year-old fluke multimeter is 5x  faster than this hantek on DMM mode reading Resistance is very slow &  IT TAKES FOREVER TO READ A CAPACITOR VALUE !!!

Can this be fixed with a firmware update ???

Sir, I think your oscilloscope doesn't have a signal source.
It was our fault.  Label model and in ...

Hi the seller on Aliexpress won't replace it because
the protection time has expired.

Method 1:
First turn off the scope and connect the scope to your computer.
Press F1 and power button at the same time until the indicator in the lower right corner flickers.
Can oscilloscopes stay in DFU mode?

Method 2:
Remove the two batteries.
Press F1 and connect the scope to your computer at the same time.
Can oscilloscopes stay in DFU mode?

Sorry, the measurement rate is determined by hardware. Can't be improved by firmware.

Hello,
I've received a new 2D42 yesterday and it was working fine. I've tried to upgrade firmware by following the instructions found on this forum (using firmware and update tool from this page http://hantek.com/en/ProductDetail_1_13174.html, updating using Windows 10) and the update failed right after the flash was erased (see screenshot).

Now the device is dead and cannot start anymore (not even in DFUse mode ...)
Any way to recover and unbrick it ?
Thanks in advance for your help.
