Hi!
On my Mi 5X installed "MIUI 10.2 by xiaomi.eu 8.11.1 Beta".
Now i try to install this rom via TWRP, but it is not successful.
There is message, that this ROM is for "tiffany", but my system is "".
When I bought this smartphone, there was installed AndroidOne and it was named "tissot" (i don't remember exactly, on the box written MI5X), so i was change it to "tiffany", unblock bootloader and after it successfuly install ROM from xiaomi.eu.
A long time i don't update rom via "Updater" application, and now i can't do it ((
Later i will see via adb what version it show now ("tiffany" or something another).
Maybe i need to install an earlier version, and after it try to install 9.3.28?
