Did you get an original colour tray or just one of the many "generic coloured" ones available on eBay ? If the first I would be very grateful if you could share the sourceI'm waiting for the double tray to arrive and I'll try the European rum. If it does not work, I will flash Xiaomi.eu rom. I have this setting in my Mi10 with stock rom. This is single sim version.
Thanks,
Axel
