Two weeks ago I ordered at the company batronix an mso5074, which software version 01.01.04.04 on it. After reading through pages 20 to 47 I was confident enough to install the patched firmware. With that the oscilloscope has now all features enabled.
On general remark though about this oscilloscpe, which has nothing to do with the patch, is that the input impedance cannot be switched to 50Ohms. The option is greyed out. Standard is 1MOhm. And we would need to use external feed through terminators to realize this. If someone would need this, the option would be to go for the MSO7000 Series. I have not seen anywhere if someone was able to patch that oscilloscope as well with success.
