I just purchased Windows 7, again so I can unlock my Mi Mix 2. I believe I own it a few times from way back buying different computers throughout the years but I couldn't locate anything that would pass verify on Microsoft site when I tried to download it to make a bootable windows USB. When I put in the key code on my current laptop they replied and told me I would have to get ahold of the manufacturer because it came with the computer which is true but what a major pain in the ars! This is my only complaint about my Xiaomi phone. When it comes to Android across the board I believe the go to default setup is and should be Linux. It was cheap for a official legal key code for windows 7. Now to make a bootable USB and wipe my laptop and unlock my bootloader then wipe it again and reinstall Linux. Yay.
I vote that we should have the simple "fastboot oem unlock" type command to unlock Xiaomi devices. Hopefully some day they go that route. I really dislike windows. 🤯
Oh well anyone having the same issue check out windows 7 on eBay there's some real official cheap packages available.
