It’s really been a wonderful news for OnePlus 3/3T owners. If you were using Xiaomi device and recently got upgraded to OnePlus 3/3T (and miss the sweet MIUI), you could easily install MIUI 9 based custom ROM on your device. You might know, installing custom ROMs require root access and a custom recovery installed. In case if your OnePlus 3/3T isn’t rooted yet, do that first.

I have already covered several guides to manually update OnePlus 3/3T versions to various OxygenOS builds (including the latest releases) and you may refer it for flashing the stock OS if you wish to. However, in this tutorial, I will be guiding you update OnePlus 3 to MIUI 9, running on Android Nougat 7.1.

MIUI 9 ROM for OnePlus 3/3T: Pre-requisites

  • Keep your data safe. Backup everything before performing such developmental tasks.
  • Your OnePlus 3/3T should be rooted and installed and custom recovery.
  • Maintain more than 50% battery juice on your device to prevent power failure while installing ROM, which may cause device bricking.

The ROM is currently in alpha stage and which means, it might have a few bugs for daily usage. If you want a stable ROM, either stick with your current OxygenOS version or wait till the developers release an update for this MIUI 9 ROM.
