i have a doubt...i was in original miui 9 global before...must i install the original chinese rom to get the best compatibility with this amazing eu build? i ask that because every time im on TWRP and i flash new EU builds there is an error and look like anything is flashed, but at the end when i reboot the phone the builds are flashed.Download the rom using pc, reboot your phone to TWRP, plug to pc, you can access your internal storage thus you can copy the rom to your phone.
