Hack Rigol DS1074Z-S PLUS

[ElettroFabio]

Hello, I'm new to the forum and start right away with the excuse for my bad English. However, I have recently bought the DS1074Z Rigol S-Plus and the first thing I immediately tried to unlock all options with this guide:
but inserting the codes generated by "Rigup" oscilloscope I shows: Invalid License!
Any of you have the solution to this problem?

Any of you have the solution to this problem?

The plus models can't be hacked with simple unlock codes.

This is the thread where people are trying to hack them (with limited success)
