Xiaomi Mi6 users can actually update to the beta version of Android Oreo thanks to the new Global Beta ROM based on the latest version of the operating system.
Xiaomi has released the first beta version of Android Oreo for the flagship Xiaomi Mi6. We are talking about the Global Beta ROM in the version 8.1.11: in case you don’t know, it is the beta version of the international ROM with Google services installed. If you have the MIUI 9 Global Stable ROM and want to taste the latest version of the operating system on your Xiaomi device, you will have to switch to another ROM first.
To upgrade your handset to its first beta of Android Oreo from the Global Stable ROM, you have to upgrade it to the MIUI 9 Global Beta ROM v7.12.14 based on Android Nougat. Only then you will be able to install the Android Oreo beta successfully. Once you updated to v7.12.14, you will receive an OTA notification which will automatically update your device. If you are not an expert and you do not know how to flash a ROM, follow the link at the end of the article and you will head to a detailed guide for your Xiaomi Mi6.
