How to Install MIUI 9 on OnePlus 3/3T [Custom ROM]

Download MIUI 9 ROM for OnePlus 3/3T. Now manually upgrade your phone to the latest MIUI version with this custom ROM. Step-by-step guide.

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.

  1. Download the ROM (MIUI9_OP3x_Hito_7.8.6_alpha.zip) from the above download section.
  2. Copy the same to your phone’s internal memory. (Do not extract them)
  3. Now reboot your device to the custom recovery (TWRP Preferred). For this, use the hardware key combinations after switching off your phone.
  4. Once your device is booted into the recovery, clear cache, data, Dalvik and system.
  5. Now choose the copied MIUI 9 ROM file and flash.
  6. Once you flashed the ROM, clear cache and Dalvik again.
  7. Reboot system.

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.
