Hello
I only used my Hantek 2D72 a few times, and now it`s completely dead. Tried different batteries and cables, but no success. All updates installed. [Bought from Banggood]
Any suggestions?

Tnx

This seems to be a fairly common problem with this devices, the solution given by Hantek is to re-flash the firmware via a serial interface existant on the board (although I think it might be an easier solution but I need to test it).

The link from the thread above with the files and instructions has expired, wait a bit that someone from Hantek will repost it to you, or try to email them directly.

1: Amy, can you please supply the correct files and instructions how to connect?

2: Does this affects the calibration of the unit?

Tnx

Apparently Hantek's support is too busy...

Fortunately, I've saved I copy of the files with instructions just in case I ever needed. You can find it in this link: https://fil.email/VNBbJBoI

May I ask what you have done, and then the device can not boot?
If you bought it before September 2019, you can refer to the attachment uploaded by oasj2yeehbqo1 to program arm1 and arm2.

Thank you for OASJ2YSeeEhBQo1's answer.

HI, I bricked my Hantek while trying to update the firmware too.

From the advice on the forums, I used prolific USB to TTL cable (with older driver 3.20.0) to connect and upload the USB_Bootloader_v2.0.bin file and it is working again!

This video was very helpful;

If you want you can try another way while you wait, it won't make things worse anyway... Try this: (considering you already tried the steps given in this thread https://www.eediscuss.com/forum. ... 14930&fromuid=26055)

1- Install the Dfuse driver, available in the same file I posted in my last post.
2- Download this file: https://fil.email/8MTsdbSA (it is the last version of the FPGA and FW)
3- Extract it to the folder: C:\Program Files (x86)\Hantek2xx2\AutoUpgrate (I'm considering you have the Hantek2xx2 software already installed in your computer, if not, install it first) - Remove any other .dfu and .bin files in the folder, if any. Keep the file names as it is, don't change it.
4- Connect the device to yours computer's USB. Keep F1 button pressed and power on the oscilloscope, wait about 2 seconds and you should see the Run/Stop button flashing. The device is now in programming mode
5- Run the program HT2000Update.exe (it is in the folder: C:\Program Files (x86)\Hantek2xx2\AutoUpgrate)
6- Select the option "local files" and then "start". Wait the process to complete. This should re-flash the device's memory.


You might need to restore the default settings of the oscilloscope for it to work properlly.
