Roborock S5. Error "Access denied"

[Luckasas]

Hello,
I have installed valetudo in a Roborock S5. I've tried to access Map but always show "Error loading map data". I've also tried Map reset but it shows "Error".
The log is this:

That's the firmwares region lock triggering because it's a CN unit.

How can I change firmware lock?
