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

echarlus

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.

Hi thanks a lot for the info.
One question regarding the TTL to USB device, should I get one using  3.3V or 5V signals ? I see both model exist ...
Thanks

You should use 3.3V.

Hello,
I've tried to follow the procedure described in "rogram Arm1" but the Flash Loader demonstrator keeps on saying that there is no response from the target (I see a brief led flashing on the USB to TTL board).
I've checked that I've installed the proper drivers for the USB to serial device and this part seems to be working ok (device is detected, USB port is created).
I did put a jumper between the 2 pins as described and then I plug in the USB cable in the computer.
the Flash loader states "Verify the boot mode configuration" and the flash protection status (see screenshot); I've only set the jumper, is there anything else to do on the scope (hit a combination of keys to start it in the proper mode ? I've tried power+F1 with no success).
Thanks for any advice ... I'm quite stuck here

Connect RX to TX and connect TX to RX

Thanks for the hint (I should have thought of that ...) unfortunately it did not solve my problem. Still the same error from the software (I still have a led flashing briefly on the USB to TTL device and that's it).
Any other hint I could try ?

Hi,
I finally managed to flash the device, my problem was caused by vmware ...
I managed to get a PC with native Windows and it finally worked....
Thanks for your help !
