Xiaomi’s smartphone firmware is a controversial topic, with some updating at the first notice, others ignoring new MIUI versions for years for fear of losing stability. Meanwhile, the right firmware can both revive an old device and turn a new flagship into a “brick.” Why does the manufacturer regularly release updates, and should they be trusted?
In this article, we will discuss the real reasons why Xiaomi firmware can be useful (or vice versa – harmful), what types of updates are available, and how not to run into pitfalls. Spoiler: not always the new version of MIUI is better than the old one, and sometimes a rollback to the previous release is the only way to return the device to work.
1. Why Xiaomi is releasing new firmware: the official version vs reality
According to Xiaomi, each new firmware is designed to improve the user experience, and press releases have included phrases like “performance optimization,” “expanded security features,” and “innovation capabilities,” but in practice, the motives are far more prosaic:
The real reasons for the MIUI updates are:
- 🔒 Closing vulnerabilities – critical bugs in Android or Xiaomi proprietary components are often exploited by hackers. Updates close these holes, but not always in a timely manner.
- 📱 Support for new devices – firmware for flagships (for example, Xiaomi 14 or Redmi Note 13 Pro)+) Often contain drivers for fresh hardware, which are not in the old versions.
- 💰 Monetization - new versions MIUI Often add ads to system applications or integrate paid services (for example, Mi Cloud Pro).
- 📊 Data Collection – Updates can extend telemetry collection capabilities (even if you have disabled it in your settings).
Fun fact: Xiaomi often releases firmware labeled "stable" that actually contain critical bugs. For example, in MIUI 14.0.4 for Poco F5, users complained en masse about overheating of the processor and fast battery discharge. The manufacturer fixed the problem only after 3 months.
⚠️ Note: If your smartphone is more than 3 years old (e.g. 2020 Redmi Note 9), updates MIUI This is due to Xiaomi’s policy of encouraging the purchase of new devices.
2.7 Real Pros of Updating Your Firmware (When Justified)
Despite the risks, in most cases, firmware is beneficial, and here are specific situations where the update is definitely needed:
| Reason for updating | What gives the user | Example (model + version of MIUI) |
|---|---|---|
| Correction of critical bugs | Removes freezes, reboots, sensor problems | Xiaomi 12T on MIUI 13.0.8 → Fixed black screen bug after call |
| Support for new communication standards | Adds 5G, VoLTE, Wi-Fi 6E | Redmi Note 11 Pro on MIUI 14.0.2 → VoNR support (voice on 5G) |
| Optimizing the battery | Reduces the charge consumption in standby mode | Poco X5 Pro on MIUI 14.0.3 → Work time has increased by 15% |
| New camera features | Adds shooting modes, improves photo processing | Xiaomi 13 Ultra on the MIUI 14.0.6 → Dolby Vision is now available. HDR video |
| Security | Closing vulnerabilities in Android and MIUI | All devices on MIUI 14+ → CVE-2023-2129 vulnerability patched |
Important: If your smartphone is in the MIUI beta program (for example, through Mi Pilot), you will get new features 2-3 months earlier than others, but the risk of running into unstable firmware increases by 5 times.
3. When firmware is harmful: 5 cases when it is not worth updating
The new MIUI version is not always better than the previous one, but here are the situations where the update can make the smartphone worse:
- 🔋 Older devices (released before 2020) – firmware for them is often poorly optimized. For example, the Redmi Note 8 Pro after upgrading to the newest device MIUI 13 started warming up and braking.
- 🎮 Game smartphones (Black Shark, Poco F series) - new versions MIUI You can remove game chips (such as physical triggers on Black Shark 5).
- 🔒 Custom firmware – if you’re using xiaomi.eu or PixelExperience, the official update may block the bootloader.
- 📱 Regional restrictions - firmware for the global version (MIUI Global may remove features only available in China (e.g. Super Wallpapers).
- ⚡ Unlocked bootloader - update via OTA It can lead to a breech (complete loss of performance).
Example: Xiaomi Mi 11 user upgraded from MIUI 12.5 to MIUI 13.0.1 and lost support for LDAC (codec for high-quality Bluetooth audio), the function was returned only through a rollback to the old firmware.
⚠️ Note: If you use Xiaomi with an unlocked bootloader and Magisk installed (for root rights), never upgrade through OTA. First, download the full Fastboot or Recovery package and manually run through the Mi Flash Tool.

4. Types of firmware Xiaomi: which one to choose?
Xiaomi offers several types of firmware, and not all of them are suitable for the average user.
| Type of firmware | For whom? | Pluses | Cons |
|---|---|---|---|
| Stable (stable) | Regular users | Less bugs, time-tested | New features appear later. |
| Beta (beta) | Enthusiasts, testers | New features first | May contain critical bugs |
| Global vs China | Depends on the region. | Global – Google support, China – more MIUI features | China without Google services, Global may not support some chips |
| Custom (xiaomi.eu, PixelExperience) | Advanced users | More customization, no advertising | Could break warranty, risk bric |
Tip: If you’re not sure which firmware to choose, check out the feedback on the forums (4PDA, XDA Developers) for your model. For example, for the Redmi Note 12 Pro+, users often recommend xiaomi.eu instead of the official Global due to the lack of advertising and additional features.
Make a backup of data (via Mi Cloud or TWRP)
Check the battery charge (at least 50%)
Download the correct firmware version (for your model and region)
Disable antivirus (can block firmware files)
Have a USB and PC cable on hand (in case of problems)

5. How to update the firmware safely: step-by-step instructions
If you decide to upgrade, follow this algorithm to minimize the risks:
- Check the current version of MIUI: Go to Settings → About Phone → MIUI version. Remember the current build (e.g. V14.0.3.0.TKCCNXM).
- Select the method of updating: 📲 OTA (airborne, the easiest, but not always safe way, suitable for official firmware. 💻 Through Recovery – if you have an unlocked bootloader or custom recovery (TWRP). ⚡ Fastboot – for full flashing (requires PC and Mi Flash Tool).
Download the firmware.
Official firmware is taken on the Xiaomi website (choose your model and region!). For custom - verified sources (4PDA, XDA).
Install the update
For OTA: Settings → System Update → Select a file.
For Recovery: Reboot to Recovery (Power + Vol+), select Install → Select ZIP.
If after the update, the smartphone got stuck on the Xiaomi logo (bootloop), try:
- Wait 10-15 minutes (sometimes the first download is long).
- Reset to factory settings via Recovery (Wipe Data).
- Switch back to Fastboot.
If the problem hasn’t gone away after 2-3 days, try rolling back or flashing a custom core (e.g., FrancoKernel for Poco F4).
