- Fixing Boot Loops: Best solution if your phone is stuck on the “Redmi” or “Mi” logo.

- Removing Screen Locks: Easily bypass forgotten patterns, PINs, or passwords.
- System Stability: Clean out deep system bugs that a factory reset cannot reach.
Essential Pre-requisites
Before you begin the process, please ensure you complete these preparations:
- Battery Level: Maintain at least 60% charge to prevent an accidental shutdown.
- Data Backup: Because this process erases everything, secure your photos and contacts to a PC or Cloud.
- USB Cable: Also, use a high-quality or original Type-C cable for data integrity.
- Drivers: Your computer requires the correct Qualcomm and Xiaomi drivers. You can obtain the Latest Mobile USB Drivers here.
- Flashing Tool: Finally, access the official Mi Flash Tool Setup here to execute the process.
Step-by-Step Installation Guide

- Extraction: Unzip the firmware package to your desktop. However, make sure the folder path does not contain any spaces.
- Fastboot Mode: Power off your phone. Then, hold the Volume Down + Power buttons until the Fastboot bunny icon appears.
- Connect to PC: Connect your Redmi 12 5G to the computer using your USB cable.
- Launch Mi Flash Tool: Open the tool, click “Select,” and navigate to your extracted “sky” firmware folder.

Frequently Asked Questions (FAQ)
Q: Will this flash file work on the Poco M6 Pro 5G?

Q: Is the April 2026 security update safe to install manually?
A: Yes. Consequently, installing it via Fastboot is often safer than an OTA update if you are currently facing system bugs.
Q: What if I get an “Anti-Rollback” error?
