How to Install a developer ROM in Xiaomi Mi3

Here We are going to discuss about installing a developer ROM in Xiaomi Mi3.

You have to download the developer ROM from their official website here
(source MIUI.COM. You can download many ROMs available for the popular devices from the link).

You just have to download the developer rom by click on the first download link.

Now you have to copy the downloaded ROM file to the 'downloaded_rom' folder of the SD card. If the downlaoded ROM is a newer version, then you don't have to wipe the data, but if the ROM that you have downloaded is older version, then you will have to wipe the data.(The phone will automatically detect and inform you if it is a newer version).

Open the updater on the launcher and then select installation file.
Now select the ROM which you want to flash and click update now.

That's it , updation will start and you will have the New ROM installed.
