DSO3254A will not start with Windows app

PlusPlus

The USB device is detected, but with an invalid firmware version.  Note that when the device is plugged into the PC, only the Power stays on.  How can I fix this?

PlusPlus

I have already done this and the results are the same.  The software does not find the USB device.

PlusPlus

Is there a way to reset the unit to factory settings or to reprogram the firmware?

PlusPlus

The "Utility-Factory Setup" option is part of the Windows application which will not work because (as stated previously) the USB device is not found.

The IO Libraries suite install correctly and as of today, the DSO3254A is no longer detected at all when it is plugged into my PC.  Please note that I also own a DSO3254, which works perfectly.  It is only the 3254A which stopped working last week.  Note that I have also tried installing everything on another Windows 10 PC without success.  In both cases, the DSO3254 works fine, but the DSO3254A is not detected at all when plugged in.

The attached images show what the IO Libraries Connection Expert displays for my DSO3254A and the resulting error in the DSO3000A Windows application.

My DSO3254A is only about six months old.  Is it still under warranty?  Since none of the advice provided here has solved my problem, how would I go about getting the unit repaired?

PlusPlus

Yes, I would!  I just sent an email to you.

Many thanks to huhai_1000 (caiyijun@hantek.com) for sending me the tools and directions for re-initializing my DSO3254A.  It is now working perfectly!
Thank you and best regards.

This was finally fixed after seeing this thread with a newer release of the DSO3254a firmware than was sent to me in 2019.  Happy to finally revive what had become a dead piece of test equipment, but disappointed that it took so long to get a solution.
