Unlocking Xiaomi smartphones with 4PDA: a complete guide with risks and solutions

Unlocking the bootloader on Xiaomi smartphones is a must for installing custom firmware, obtaining root rights or restoring bricks. The 4PDA Forum remains the main Russian-language resource where the current instructions, firmware and tools for this procedure are collected. However, since 2026, unlocking rules have been tightened: the company requires binding to Mi Account, waiting 7-30 days and complying with strict conditions. In this article, we will discuss legal and informal methods of unlocking through 4PDA, the risks of blocking an account, as well as alternative solutions for models that are no longer officially supported.

It is important to understand: the procedure is different for devices on Qualcomm and Mediatek, and also depends on the version. MIUI (global, Chinese, EEA). Nana 4PDA There are often workarounds for new constraints, but they require technical training. If you're a beginner, start with the official method, even if it takes longer.

• 🔹 Up-to-date firmware: users quickly upload the latest versions of Fastboot and Recovery firmware, including those that have not yet appeared on official Xiaomi servers.
• 🔹 Bypass solutions: here you can find unlock methods for devices with a locked Mi Account or a lost password (for example, through the use of a password). SP Flash Tool for Mediatek).
• 🔹 Support for older models: even for smartphones released 5+ years ago (for example, Redmi Note) 4X or Mi 5, on 4PDA work instructions.

However, there are downsides to this approach: First, some “circumvent” methods can lead to a Mi Account block without recovery — especially if leaks of Xiaomi’s internal tools are used. Second, there are outdated guides on the forum (for example, for MIUI 10, when the procedure was simpler).
