Why I can't change my phone language from Spanish (M?xico) to Spanish (Spain)?

[Windows Central Question]

I'm from M?xico, and I just acquired a 920, wich, in my country, ain't got the Denim upgrade, so I just have the preview for developers. Even then, Cortana is able to work in Spain (switch language to Spanish (Spain) and region settings to Spain), and well, I had it in my 635 just switching those things, but, it looks like I can't change my phone's language from Spanish (M?xico)... I actually tried with the recovery tool, erasing everything and reinstalling the OS, but, even then, I can't do it, it remains the same... It would be great if someone in here could help me, please :/

Not sure if this helps you but in Settings > language > you can add languages but the language you want to use on your phone has to be on the top of the list.
So if Spain (Mexico) is on the top of the list and Spain (Spain) on the second place tap Spain (Spain), a pull down menu will come, and push "move up" till it is on the top of the list.

I think ita something about LTA CV ROMS, try hard reset and set everything in English and update when all updates are installed try to change the language to Spanish, if this doesn't work install, a rom from some operator like movistar that already have denim

Thanks, but I did both... Harrie-S, that is what I did the first time, and after the reboot, it remains on Spanish (M?xico)
Kean5326, I did the hard reset, even tried with the NSU and the recovery tool, and it was both useless... I saw the last time I checked the list of available countrys and carriers for Denim, and there was no one available in M?xico for 920 :/
Thank you both for the answers
