Interesting. Now, I've 262hrs to go. I guess it's possible that if I reset the device to factory and then clean install the miui 10 global beta ROM, I might just be able to unlock it afterwards. But if it goes sideways, it might reset the timer back to 360hrs. Damn... Not a good idea at all.
I think that you do not have to wait anymore with miui10, I read something like that in the changelog
