Hello. When flashing it is important to charge the batteries and use the laptop then there will be less problems. Try updating again by turning on boot mode by holding down the F1 key and pressing the power button. If it does not help, then just flashing through the programmer directly. I didn’t write in more detail because if not skillful actions can damage the device, it is used for programming STM ST-Link Utility

Thank you for the message, could you please send info in regards to flashing through the programmer directly. It is my only choice since the F1/Power combination does not work. Also the PC does not recognize the device. Thank You!

Thank you very much! I followed your instructions precisely but unfortunately I cannot connect to the device. I used USB to TTL module with no luck.
Your help is much appreciated. Have a great day!

Hello, during the firmware update 2D42 I had the same problem (the process was interrupted and the device is no longer turned on). F1 / Power combination does not work. Can you please tell me how to restore the device?

Author: amy Time: 2019-3-26 16:55
Connect the scope to your computer, open Dfuse Demo. In Device frame, will "STM Device in Dfu Mode" be displayed?

If there is, please update again and keep the USB cable line not moving at the same time.

Device 2D42 does not turn on, it is impossible to transfer to the programming mode. Previously there was an interrupted procedure for updating the firmware.

Hi Amy.

Received some days ago a brand new 2d42. it was not with the last fw version so I decided to update it using DfuSe Demo package and HantekHTX2019110801.dfu.

I Uploaded the dfu file under "Upload Action" instead of using the "Upgrade" section. I noticed that as at the of the loading phase the scope did not reboot.
So I retried using the right section of DfuSe (Upgrade), but right after pressing the Upgrade button, it hangs in "Erasing Phase". After a bunch of minutes (more than 15) it was always there.

I had to detach it from the PC, but now it won't power-on any more.
I have found the software and instructions you provided, so I will try to follow them and make the scope revive.I will give you a feedback on that.

Just a couple of questions:- about USB-to-Serial adapter, should it be a 5V or a 3.3V ?
- do I have to connect power through the USB-C cable while connecting the USB-to-serial cable ?

Thank you in advance.

USB-to-Serial adapter should be 3.3V.
If you use usb-c cable to connect the scope to computer, you don't need to connect VCC connector of USB-to-Serial adapter.

Sorry to bother you but, there is something strange.
Done what you suggested through usb-to-serial cable worked but, after that, I wanted to repeat the update to the latest firmware.
Tried through DfuSeDemo, and got the same problem as before, so it hangs in "Erasing Phase".

I then unbrick newly the scope through the procedure. It worked again ok, but why I cannot upgrade to the latest firmware ?
I tried the DfuSe upgrade with older versions of the fw and with those images all went ok. Only the last fw version won't upload.
Is there a specific reason why ?

I noticed the last fw is 513KB, while the older ones are not more than the half. Could be that with my previous wrong action I have "broken" something within the flash memory ? Is there something I can do to solve this issue ?

Thank you in advance.

Understood. Fw dfu file is 513K as it was overwritten with the "Upload Action" I made.
So, it is not the right dfu file that should instead be around 220KB.

Author: Marceloo Time: 2020-7-7 08:28
hi, I was able to reset the oscilloscope by reading the procedure that is in the forum, but I want to clarify that it only worked for me when I connected the vcc (3.3v) pin to the board, without that pin connected the software did not detect the oscilloscope.

Author: Marceloo Time: 2020-7-7 09:27
Can you tell me what is the latest firmware for the 2D42? Thank you

Author: amy Time: 2020-7-10 08:28
Please scan the QR code on the back of the oscilloscope to download the software and install.
Now run the software and click "Help->Checkupdate" to update as prompted.

Please remove the batteries and only use the power adapter for power supply. Can the oscilloscope be turned on?
