Title: Startup problem with DSO4004C Series
Customer Consultation:
Hello,
Specifications of my device are:
200 MHz bandwith, built in function generator.
The device is over 3 years old. Since yesterday the system does not boot anymore.
At startup I get a screen like this:
file:///C:/Users/Tina/AppData/Roaming/Foxmail7/Temp-12340-20230116074704/Attach/X6svNm7naedWF40V(01-16-08-23-03).png
I tried options F1, F2 and F3 several times without success.
I also managed to open the Oscilloscope and connect my PC to the serial interface (at 115200 kbaud 8n1).
I added the startup log to this email that I get at startup over the serial interface on my PC.
Is it possible to get the latest recover*.up recovery file from you ?
I also downloaded the latest firmware from your website (dso4kb_20211207.upk).
Is it possible to install/flash this firmware over the serial interface ? - If yes, please tell me how to do this.
I can connect to my USB Stick through the serial Interface when the USB stick is inserted in the oscilloscope.
I also have a litte bit of knowledge in using the linux console.
Thanks in advance your your help.

Please refer to the document to recover the backup system from SD card.
If there is no SD card, please try to contact your seller to repair it.

Hello,
Can you please help me with the SD card firmware so I can repair my oscilloscope? It had crashed and no picture on the screen, and looks like it cannot boot anymore. I cannot update the firmware because I see nothing on the screen. Serial number: CN1838002002099. Please send me the recovery SD card content so I can repair it. Thank you so much
