For Downloading Fastboot Rom you've to check these things that if your device is Global Variant then you've to download Latest Global Beta Rom, if your device is Chinese Variant then you've to download Latest China Beta Rom . If you flash Global Rom in Chinese variant it won't boot with locked bootloader. So make sure your device variant and then download rom.

Now extract the Rom (check if the ROM file suffix is '.tgz'. If it is '.gz', please rename it to '.tgz'). Select the Rom Folder in Mi Flash Tool (Make sure there is no space in the rom address if there rename all folders with an underspace (_). The address should like this, C:\Users\Akib\Desktop\whyred_global_images_8.7.12_20180712.0000.00_8.1_global

After doing this check the option 'clean all' at bottom of the tool. Then Flash it. When it will successfully flashed, connect your battery, cover the back shell and power on device. It should boot up. :)

Part Two - How to get rid of Fake Global Rom/Custom MIUI Rom, Fake Unlock

How to check if your device has fake global rom? Go to About Phone Rom Version. If you see the version is something like this xx.xx.xx.xx.xx.xx then your device has fake global rom. Official Rom should like this xx.xx.xx.xx That means in official rom version there is only four section of numbers and three dots. Also do search in Google and check that version is official or fake! In Fake Rom you will not recieve any OTA Updates. Or even you cannot unlock your bootloader, because there is a fake unlock installed. To check go to Developer Options of your device and see Mi Unlock Status, it will see Unlocked, but if you check through fastboot command 'fastboot oem device-info'. it will say locked.


So how to get rid of it? Do what is said in Part One carefully. Now you have official rom installed. You can recieve OTA updates and also unlock your bootloader now!
