Last week Xiaomi released an OTA update (build MIUI v6.5.4.0 LXIMICD) for Mi 4i smartphone to fix the overheating issue, but it was stopped immediately due to certain issues. Now the company has released a new update (version LXIMICD) by correcting all issues and the OTA (over-the-air) update has started rolling out to all Mi 4i phones in India.

In this guide, we show you how to update Xiaomi Mi 4i to the new firmware MIUI v6.5.5.0 (LXIMICD) manually. The update will fix the overheating issue in Mi 4i. If you have not received the OTA notification for some reasons (it will take some times to reach on your phone), read on to know where to download the firmware and how to install it manually on your Mi 4i.



Although the Mi 4i is a lower spec variant of the original Mi 4 for India, it is a great device with 1.7GHz Snapdragon 615 octa-core prcessor, 2GB RAM, 5-inch (1920×1080 pixels) IPS OGS display, 16GB internal memory and a 3,120mAh battery with quick charge support.
