The update bumps the software version to V12.0.4.0.PEFCNXM. As a China-exclusive ROM, it is currently being rolled out in China.

But thanks to the awesome community the Redmi S2/Y2 ‘s MIUI V12.0.4.0.PEFCNXM China ROM is made available for download, so anyone who wants to flash the ROM manually on Redmi S2/Y2 can do that.

FYI, the current update is a Chinese Stable ROM which means only those devices running on a China ROM, will get the update via OTA. Otherwise, you have to install it manually. The update is based on Android 10.

You can manually check the software update on your device whether it’s available on your device or not. Head over to the device Settings –> About Phone –> Check for Software Update. The update will be rolled out globally in an incremental manner and it should take some time to appear on all the units.
