Update : How to Flash Windows 10 ROM on Mi 4, Download link included.
Windows ROM for Xiaomi Mi 4 was available for developer some months ago that could be downloaded following a certain process, but they removed it later. Since that time Windows ROM for Mi 4 is in rumor, but it has been confirmed officially now.
Xiaomi Founder and CEO, Lei Jun has officially confirmed that Windows 10 ROM for Xiaomi Mi 4 will be released on 3 December. Once Windows 10 ROM is released, we expect it to be available on http://en.miui.com/download-240.html, and then users can download and flash it. We have not heard anything about other models, they may release later if users like it.
So if you want to try Windows 10 on your Mi 4, get ready for this. Windows Phones are not as popular as Android. However, Users would love to try for sure, but most of them are expected to go back to Android Platform. MIUI is Xiaomi’s official OS based on Android, and it comes with more customize options, and there are millions of apps that are available for Android devices. So it would be tough for Android users to continue using Windows 10 OS, but it’s good to give it a try.
