Hello,
I'm having problems with a RIGOL DS 1064B oscilloscope, I upgraded to a newer version. After this upgrade the oscilloscope does not work anymore and the USB ports are no longer active). So on the USB ports I can no longer try anything to downgrade.
Please if you have a software version for flash memory S29GL064N90TFI04 for this type of oscilloscope, I mention that the hardware version is DB4.5.
After this upgrade it shows me software version 012.01.00.04.01, I don't remember well but it seems like the version it had before was 02 or 03.
I can rewrite the firmware with the programmer in the flash memory S29GL064N90TFI04.
Thanks to those who can help me, from the bottom of my heart.
