New Hantek DSO2X1X models?
DavidAlfa:
You got it! Should be it. What else if not?
Damaged FPGA? Strange, but go figure.
Maybe they called them "LemonTrees" because they didn't pass QA and GoWin didn't want to its name there.
Joemega:
...sorry for my bad english...
Maybe, your problem is the same like mine DSO2D10 after a few month: suddenly shortcut in one of rotary encoder case (GND) to the inner encoder PCB.
It's blocking the data lines.
Mine repair was simple: teardown the encoder case, a little tape to isolate.
Search this video in YouTube: "Hantek DSO5202P: Knobs/Encoders Not Working Repair"
Maybe helping you...

Hello experts!
I got a DSO2D15 and I started making backups. First I used Backup_Builder so now I have all the files it produced. Then I made a safety backup with Dsoflash and it produced the 135168kB file. Then at the first power cycle the problems started. Serial and Hardware in system information show "undefined", so i tried to update them using the file "dso3kb_CN2318029043950_Model.upk", but I got an error:
Updated failed! Error code is -2
I tried also the USB fix update, the latest update from Hantek site, the full update I have got from Backup_Builder, even do_other_update without any script (just to test if it runs), all throw immediately the same error:
Updated failed! Error code is -2
I also tried the "Default setup" key, nothing changed.
Also tried in the Keysight Connection Expert console
PRIVate:SET:PCB "003.002.001.000.000.000.000.001"
error:
! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)
and
PRIVate:SET:SERIal CN2318029043950
! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)
however, the command:
PRIVate:FACTORY:RESET
reboots the scope, but returns error
-> PRIVate:FACTORY:RESET
! VI_ERROR_IO: I/O error
Visa ErrorCode: 0xBFFF003E (-1073807298)
What is weird is that after every power cycle the scope seems to forget some of the settings (if I disable the sound, it comes back at next power on); or if I save the settings in the internal memory it says it was done ok, but when I recall them it say "Recall failed".
Before making backups the system info showed (it looks to me that there are the latest versions of software and firmware):
Model: DSO2D15
Serial CN2318029043950
Software 1.0.3.0.0(230327.00)
Hardware 003.002.001.000.000.000.000.001
Firmware 3205
So my question is: is it any way to get back the update functionality? and as a bonus to set the serial and hardware fields?
Best regards,
Ionut
DavidAlfa:
That's really weird. Try platform-tools then restoring your backupbuilder backup.
Or restoring the entire dsoflash backup.
IonutL:
It doesn't work. Platform-tools ends in error:
