WARNING!Before you update the firmware on your Hantek DSO2x1x, you may want to consider the following:
1. Some firmware updates have been shown to cause various annoying problems and decrease the stability of the DSO internal software.
2. The firmware update process can for various reasons fail, leaving your DSO in an unusable state (i.e. "bricked").
3. In principle, it is always possible to "unbrick" a "bricked" Hantek DSO2x1x, but it's better not to "brick" it in the first place.
4. Before you get started on any firmware update, take a picture of your DSO "system information" screen.
5. Last but not least, remember the old adage: "If it breaks, you get to keep the pieces."
This is the firmware update procedure described in the Hantek DSO2000 series User Manual:
2.14.1. Update Firmware
This series of oscilloscope can upgrade the software by the USB flash disc, which needs about 5 minutes.
The firmware is upgraded by the following steps:
1. Plug the USB flash disc in which a firmware program is saved in USB Host interface on the front panel of the oscilloscope.
2. Press [Utility] button to skip to the Utility menu.
3. Press Update -> Update Firmware softkey.
4. Select the file and press Multifunctional Knob to confirm. Then press Start updating softkey to update the firmware.
5. Reboot the machine after finishing upgrading, and the software version is upgraded. The oscilloscope should be
self-corrected once after upgrading.
At present there are two repositories for Hantek DSO2000 series firmware updates:

As of June 2021, there is no single firmware update that will reportedly work perfectly on all Hantek DSO2000 Series models.
List here the firmware updates available and recommendations.
