How to unlock Mi Account on Xiaomi Redmi Note 4X: Full Guide 2026

A forgotten Mi Account password, a used Xiaomi Redmi Note 4X with a tied account, or a sudden lock after resetting are familiar to many Xiaomi smartphone owners. The device becomes a brick: you can’t log in, use apps, or even perform a factory reset. The reason lies in Xiaomi’s security policy, which links the device to a Mi Account account at the firmware level.

In this article, we will discuss all the current ways to unlock for Redmi Note 4X (codenamed mido), including official methods through Xiaomi support and alternative solutions for cases where standard options do not work. It is important to understand that some methods require technical skills, and improper actions can lead to complete data loss or damage to the bootloader. We will describe each step in detail, indicate the risks and give recommendations for preparation.

Why is Redmi Note 4X blocked from Mi Account?

The Mi Account lock on the Redmi Note 4X works in three main cases:

• 🔒 Resetting settings via Recovery or Fastboot without detachment of the account.The system requires you to enter the username / password of the previous owner.
• 📱 Previous owner can block the phone through Xiaomi Cloud services.
• 🔄 Update the firmware with the transition to a newer version MIUI, where protection measures are strengthened (e.g., c) MIUI 9 MIUI 12+).

Technically, the lock is implemented through Factory Reset Protection (FRP), similar to protection on Android devices of other brands. However, Xiaomi has a feature: even after a reset via Fastboot (fastboot erase userdata command), the system can request Mi Account data if the Find Device function was previously activated.

The Redmi Note 4X is complicated by the fact that it was released in 2017 and does not support modern unlock methods through the Xiaomi Unlock Tool (the official tool for unlocking the bootloader), which means that many universal instructions from the Internet simply will not work.
