I've just did a vanilla install with CM-10.2-20131104-NIGHTLY on stock slot over SS 3.63.
Well, aparently it's gotta work because it's running the CyanogenMod splash screen. However it's taking too long to finish the first boot, so I don't really know if it's really going to happen or not. I hope it really can happen.
5min later: realized I forgot to do a factory reset after flash it over stock moto 4.1.2 --' Trying again.
Conclusion: Working in stock slot.
Moto X (XT1058)
Samsung Galaxy Tab 7" Plus (GT-P6210)
