As many of you know, Xiaomi has different variants of MIUI. Among them we find the Global and European ROM, as well as China, each of them in order to comply with the different regional regulations and legislation.

But it does not finish here. In addition, there are also other variants not developed by Xiaomi but by mobile operators., which usually customize the MIUI interface, as well as its internal settings for mobile coverage.

Unfortunately, these different ROMs developed by mobile operators (Telcel, Vodafone, etc) do not usually follow the same Xiaomi deployment plan, going at their own pace or even being totally abandoned a few months after its launch.

How to know if your Xiaomi has a carrier ROM

To find out if your Xiaomi, Redmi or POCO has an official MIUI ROM or instead, one developed by a mobile operator, we just have to go into its settings and verify the version number of MIUI. To do this we will follow these steps:

  1. Go to Settings > About phone
  2. Once inside we will only have to look at the version of MIUI

Once we have located the MIUI version, it will be enough to look at the last two letters. These indicate the developer of the ROM:

  • XM: Developed by Xiaomi
  • CT: Developed by Telcel
  • OR:Orange
  • FV: Vodafone

In this way, if our version of MIUI ends in “XM” we can be sure that we have installed the official MIUI ROM developed by Xiaomi. However, if the last letters are different, the ROM is from a carrier so we will not receive the official updates and it will be worth changing the ROM.
