DSO4072C rollback firmware version.

Magician

Hi, after I did upgrade my DSO4072C up to latest FW, oscilloscope become very slow to respond on   settings changes. Especially on encoders, I have to rotate knobs slowly, othewise it's missed  steps or change settings in wrong direction. Here the question, How I can roll-back firmware to PREVIOUS version? Now oscilloscope generates an error message, saying FW is an older version than it has already installed. But what if I want to restore older version ?

hi,Hantek's oscilloscope does not support version rollback upgrade temporarily.
but you can supply me the software edition number for DSO4072C, and we can help you solve this problem.

2. Dear sir,
   
3. Please press "Utility->system information" and give me a picture to study.
   
4. The encoders slow response, means that the encoder is broken.
