How to unlock Xiaomi Redmi via emergency call if you forget your password: Step-by-step guide

The forgotten password on Xiaomi Redmi is a situation that one in five users encounter. Especially frustrating when there is no computer to reset via the Mi Flash Tool, and access to data is urgent. One of the little-known but working methods is the use of the emergency call feature. This method is suitable for most Redmi models based on MIUI 12-14, including the Redmi Note 10/11/12, Redmi 9/10 and newer devices.

It is important to understand that the method with an emergency call is not an official unlock function. This is the exploitation of a vulnerability in the MIUI firmware that allows you to bypass the lock screen through the system menu. Xiaomi regularly closes such loopholes in updates, so the method may stop working after installing the latest version of the software. If your phone has been updated in the last 2-3 months, first check the alternative methods at the end of the article.

Before you start, consider that not all Redmi models support this trick: Snapdragon 8xx chips (like the Redmi K50) or the latest flagships often have enhanced protection. But budget and mid-end devices (Redmi Note 8 Pro, Redmi 9A) unlock this way 70% of the time. If you don't, don't despair: there are backup options in the article.
