Maybe I don't understand you. Do not confuse xiaomi.eu ROM with Global EU (EEA) ROM.
I don't understand what you want more. I already answered you that the ROM with A12 was released and even gave a direct link to download the ROM.
Then you are not using xiaomi.eu custom ROM and you are on the wrong website. This is a custom ROM forum.
If you want the official ROM, go to the Xiaomi website. https://c.mi.com/global/
