In this period of break that the MIUI development team will allow by virtue of the festivities of the autumn festival, good news is coming for the owners of the range mice Xiaomi Mi 8 and Xiaomi Mi Mix 2S that through the ROM released by the team xiaomi.eu allows you to enjoy the thrill of Android 9.0 Pie on both Chinese flagships. In particular, the ROM goes to the version 8.9.13, derived from China Stable / Developer but with sSupport native to the Italian language and above all integrated Google services instead eliminating the superfluous Chinese applications for our latitudes and tech habits.
Currently, the Global Beta for both terminals is officially present, but probably someone prefers not to wait for the release of the Global Stable or simply is better at the level of performance dictated by the ROM provided by xiaomi.eu. Recall that it Xiaomi Mi 8 suffers from the problem of anti-rollback while the 2S Mi Mix is exempt (at the moment).
If you want to check the rollback index of your smartphone, here is the procedure to follow:
Turn off your smartphone and restart it in Fastboot mode
Enter the command fastboot getvar anti
In response, you will get a number, which indicates the rollback index of the terminal. Alternatively, if the answer is empty, it means that your phone does not yet have the Anti-Rollback system
However, it should also be noted that the anti-rollback problem involves only MIUI romstherefore no problem with Custom ROMs like LineageOS etc ..
